In the early twentieth century, Chinese cultural and political modernizers worked to eliminate traditional practices as backward and unscientific. Traditional practitioners then selected elements of philosophy and practice and organized them into what they called "Chinese medicine". In the 1950s, the Chinese government sought to revive traditional medicine (including legalizing previously banned practices) and sponsored the integration of TCM and Western medicine, and in the

Ancient history

Scholars in the history of medicine in China distinguish its doctrines and practice from those of present-day TCM. J. A. Jewell and S. M. Hillier state that the term "Traditional Chinese Medicine" became an established term due to the work of Dr. Kan-Wen Ma, a Western-trained medical doctor who was persecuted during the Cultural Revolution and immigrated to Britain, joining the University of London's

criticizes attempts to treat medicine and medical practices in traditional China as if they were a single system. Instead, he says, there were 2,000 years of "medical system in turmoil" and speaks of a "myth of an unchanging medical tradition". He urges that "Traditional medicine translated purely into terms of modern medicine becomes partly nonsensical, partly irrelevant, and partly mistaken; that is also true the other way around, a point easily overlooked." TJ Hinrichs observes that people in modern Western societies divide healing practices into biomedicine for the body, psychology for the mind, and religion for the spirit, but these distinctions are inadequate to describe medical concepts among Chinese historically and to a considerable degree today.
The medical anthropologist Charles Leslie writes that Chinese, Greco-Arabic, and Indian traditional medicines were all grounded in systems of correspondence that aligned the organization of society, the universe, and the human body and other forms of life into an "all-embracing order of things". Each of these traditional systems was organized with such qualities as heat and cold, wet and dry, light and darkness, qualities that also align the seasons, compass directions, and the human cycle of birth, growth, and death. They provided, Leslie continued, a "comprehensive way of conceiving patterns that ran through all of nature," and they "served as a classificatory and mnemonic device to observe health problems and to reflect upon, store, and recover empirical knowledge," but they were also "subject to stultifying theoretical elaboration, self-deception, and dogma

Though the Shang did not have a concept of "medicine" as distinct from other health practices, their oracular inscriptions on bones and tortoise shells refer to illnesses that affected the Shang royal family: eye disorders, toothaches, bloated abdomen, and such. Shang elites usually attributed them to curses sent by their ancestors. There is currently no evidence that the Shang nobility used herbal remedies.

Post-Han dynasty
In the centuries that followed, several shorter books tried to summarize or systematize the contents of the ''Yellow Emperor's Inner Canon''. The ''Canon of Problems'' (probably second century CE) tried to reconcile divergent doctrines from the ''Inner Canon'' and developed a complete medical system centered on needling therapy. The ''AB Canon of Acupuncture and Moxibustion'' (''Zhenjiu jiayi jing'' , compiled by Huangfu Mi sometime between 256 and 282 CE) assembled a consistent body of doctrines concerning acupuncture; whereas the ''Canon of the Pulse'' (''Maijing'' ; c. 280) presented itself as a "comprehensive handbook of diagnostics and therapy."

Modern history
Chinese communities under colonial rule
Chinese communities living in colonial port cities were influenced by the diverse cultures they encountered, which also led to evolving understandings of medical practices where Chinese forms of medicine were combined with Western medical knowledge. For example, the Tung Wah Hospital was established in Hong Kong in 1869 based on the widespread rejection of Western medicine for pre-existing medical practices, although Western medicine would still be practiced in the hospital alongside Chinese medicinal practices. The Tung Wah Hospital was likely connected to another Chinese medical institution, the Kwong Wai Shiu Hospital of Singapore, which had previous community links to Tung Wah, was established for similar reasons and also provided both Western and Chinese medical care. By 1935, English-language newspapers in Colonial Singapore already used the term "Traditional Chinese Medicine" to label Chinese ethnic medical practices.

(1966–1976) the CCP and the government emphasized modernity, cultural identity and China's social and economic reconstruction and contrasted them to the colonial and feudal past. The government established a grassroots health care system as a step in the search for a new national identity and tried to revitalize traditional medicine and made large investments in traditional medicine to try to develop affordable medical care and public health facilities. The Ministry of Health directed health care throughout China and established primary care units. Chinese physicians trained in Western medicine were required to learn traditional medicine, while traditional healers received training in modern methods. This strategy aimed to integrate modern medical concepts and methods and revitalize appropriate aspects of traditional medicine. Therefore, traditional Chinese medicine was re-created in response to Western medicine.
In 1968, the CCP supported a new system of health care delivery for rural areas. Villages were assigned a barefoot doctor
Barefoot doctors () were healthcare providers who underwent basic medical training and worked in rural villages in China. They included farmers, folk healers, rural healthcare providers, and recent middle or secondary school graduates who receiv ...
(a medical staff with basic medical skills and knowledge to deal with minor illnesses) responsible for basic medical care. The medical staff combined the values of traditional China with modern methods to provide health and medical care to poor farmers in remote rural areas. The barefoot doctors became a symbol of the Cultural Revolution, for the introduction of modern medicine into villages where traditional Chinese medicine services were used. The barefoot doctor system represents a hybrid of modern and traditional Chinese medicine (, usually translated "Integrative Chinese Medicine"), a guiding principle that has far outlived the barefoot doctor system. Nathan Sivin's 1987 translation of ''Revised Outline of Chinese Medicine: For Western-medicine practitioners to learn Chinese medicine'' (; 1972) serves as a good, though outdated, example of this principle in practice.

In 1841, the British government of Hong Kong issued an announcement pledging to govern Hong Kong residents in accordance with all the original rituals, customs and private legal property rights. As traditional Chinese medicine had always been used in China, the use of traditional Chinese medicine was not regulated.
The establishment in 1870 of the Tung Wah Hospital was the first use of Chinese medicine for the treatment in Chinese hospitals providing free medical services. As the promotion of Western medicine by the British government started from 1940, Western medicine started being popular among Hong Kong population. In 1959, Hong Kong had researched the use of traditional Chinese medicine to replace Western medicine.
Historiography of Chinese medicine
Historians have noted two key aspects of Chinese medical history: understanding conceptual differences when translating the term , and observing the history from the perspective of cosmology
Cosmology () is a branch of physics and metaphysics dealing with the nature of the universe, the cosmos. The term ''cosmology'' was first used in English in 1656 in Thomas Blount's ''Glossographia'', with the meaning of "a speaking of the wo ...
rather than biology.
In Chinese classical texts, the term is the closest historical translation to the English word "body" because it sometimes refers to the physical human body in terms of being weighed or measured, but the term is to be understood as an "ensemble of functions" encompassing both the human psyche and emotions. This concept of the human body is opposed to the European duality of a separate mind and body. It is critical for scholars to understand the fundamental differences in concepts of the body in order to connect the medical theory of the classics to the "human organism" it is explaining.
Chinese scholars established a correlation between the cosmos and the "human organism". The basic components of cosmology, qi, yin yang and the Five Phase theory, were used to explain health and disease in texts such as ''Huangdi neijing
' (), literally the ''Inner Canon of the Yellow Emperor'' or ''Esoteric Scripture of the Yellow Emperor'', is an ancient Chinese medical text or group of texts that has been treated as a fundamental doctrinal source for Chinese medicine for mo ...

are the changing factors in cosmology, with '' qi'' as the vital force or energy of life. The Five Phase theory ('' Wuxing'') of the Han dynasty contains the elements wood, fire, earth, metal, and water. By understanding medicine from a cosmology perspective, historians better understand Chinese medical and social classifications such as gender, which was defined by a domination or remission of yang in terms of yin.
These two distinctions are imperative when analyzing the history of traditional Chinese medical science.
A majority of Chinese medical history written after the classical canons comes in the form of primary source case studies where academic physicians record the illness of a particular person and the healing techniques used, as well as their effectiveness. Historians have noted that Chinese scholars wrote these studies instead of "books of prescriptions or advice manuals;" in their historical and environmental understanding, no two illnesses were alike so the healing strategies of the practitioner was unique every time to the specific diagnosis of the patient. Medical case studies existed throughout Chinese history, but "individually authored and published case history" was a prominent creation of the Ming dynasty. An example such case studies would be the literati physician, Cheng Congzhou, collection of 93 cases published in 1644.

Many distinguish traditional medicine in historical China from the more recent traditional Chinese medicine (TCM), which took elements from traditional texts and practices to construct a systematic body. Paul Unschuld, for instance, sees a "departure of TCM from its historical origins." What is called "Traditional Chinese Medicine" and practiced today in China and the West is not thousands of years old, but recently constructed using selected traditional terms, some of which have been taken out of context, some badly misunderstood. He has criticized Chinese and Western popular books for selective use of evidence, choosing only those works or parts of historical works that seem to lead to modern medicine, ignoring those elements that do not now seem to be effective.

TCM has also been controversial within China. In 2006, the Chinese philosopher Zhang Gongyao triggered a national debate with an article entitled "Farewell to Traditional Chinese Medicine", arguing that TCM was a pseudoscience that should be abolished in public healthcare and academia. The Chinese government took the stance that TCM is a science and continued to encourage its development.

Philosophical background
Traditional Chinese medicine (TCM) is a broad range of medicine practices sharing common concepts which have been developed in China and are based on a tradition of more than 2,000 years, including various forms of herbal medicine

Traditional Chinese Medicine: An Introduction
It is primarily used as a complementary alternative medicine approach. TCM is widely used in China and it is also used in the West. Its philosophy is based on Yinyangism (i.e., the combination of Five Phases theory with Yin–Yang theory), which was later absorbed by Daoism
Taoism or Daoism (, ) is a diverse philosophical and religious tradition indigenous to China, emphasizing harmony with the Tao ( zh, p=dào, w=tao4). With a range of meaning in Chinese philosophy, translations of Tao include 'way', 'road', ...

Yin and yang
Yin and yang are ancient Chinese deductive reasoning concepts used within Chinese medical diagnosis which can be traced back to the Shang dynasty
The Shang dynasty (), also known as the Yin dynasty (), was a Chinese royal dynasty that ruled in the Yellow River valley during the second millennium BC, traditionally succeeding the Xia dynasty and followed by the Western Zhou d ...

"A General Introduction to Traditional Chinese Medicine"
Science Press. (1600–1100 BCE). They represent two abstract and complementary aspects that every phenomenon in the universe can be divided into. Primordial analogies for these aspects are the sun-facing (yang) and the shady (yin) side of a hill. Two other commonly used representational allegories of yin and yang are water and fire. In the yin–yang theory, detailed attributions are made regarding the yin or yang character of things:
The concept of yin and yang is also applicable to the human body; for example, the upper part of the body and the back are assigned to yang, while the lower part of the body is believed to have the yin character. Yin and yang characterization also extends to the various body functions, and – more importantly – to disease symptoms (e.g., cold and heat sensations are assumed to be yin and yang symptoms, respectively). Thus, yin and yang of the body are seen as phenomena whose lack (or over-abundance) comes with characteristic symptom combinations:
* Yin vacuity (also termed "vacuity-heat"): heat sensations, possible sweating at night, insomnia, dry pharynx, dry mouth, dark urine, and a "fine" and rapid pulse.[Kaptchuck, Ted J. (2000)]
"The Web That Has No Weaver"
2nd edition. Contemporary Books.
* Yang vacuity ("vacuity-cold"): aversion to cold, cold limbs, bright white complexion, long voidings of clear urine, diarrhea, pale and enlarged tongue, and a slightly weak, slow and fine pulse.
TCM also identifies drugs believed to treat these specific symptom combinations, i.e., to reinforce yin and yang.
Strict rules are identified to apply to the relationships between the Five Phases

in terms of sequence, of acting on each other, of counteraction, etc. All these aspects of Five Phases theory constitute the basis of the zàng-fǔ concept, and thus have great influence regarding the TCM model of the body. Five Phase theory is also applied in diagnosis and therapy.
Correspondences between the body and the universe have historically not only been seen in terms of the Five Elements, but also of the "Great Numbers" ( zh, labels=no, c=大數 , p=dà shū) For example, the number of acu-points has at times been seen to be 365, corresponding with the number of days in a year; and the number of main meridians–12–has been seen as corresponding with the number of rivers flowing through the ancient Chinese empire.[''"There are 365 days in the year, while humans have 365 joints r acu-points.. There are 12 channel rivers across the land, while humans have 12 channel"'', A Study of Daoist Acupuncture & Moxibustion, Cheng-Tsai Liu, Liu Zheng-Cai, Ka Hua, p. 40]
Model of the body
TCM "holds that the body's vital energy (''chi'' or ''qi'') circulates through channels, called '' Meridian (Chinese medicine), jingluo'' ("meridians and collaterals"), that have branches connected to bodily organs and functions." Its view of the human body is only marginally concerned with anatomical structures, but focuses primarily on the body's ''functions'' (such as digestion, breathing, temperature maintenance, etc.):
These functions are aggregated and then associated with a primary functional entity – for instance, nourishment of the tissues and maintenance of their moisture are seen as connected functions, and the entity postulated to be responsible for these functions is xiě (blood). These functional entities thus constitute ''concepts'' rather than something with biochemical or anatomical properties.[Ross, Jeremy (1984)]
"Zang Fu, the organ systems of traditional Chinese medicine"
Elsevier. First edition 1984. pp. 12–13. "For example, he termXue is used rather than Blood, since the latter implies the blood of Western medicine, with its precise parameters of biochemistry and histology. Although Xue and blood share some common attributes, fundamentally, Xue is a different concept."
The primary functional entities used by traditional Chinese medicine are qì, xuě, the five zàng organs, the six fǔ organs, and the meridians which extend through the organ systems. These are all theoretically interconnected: each zàng organ is paired with a fǔ organ, which are nourished by the blood and concentrate qi for a particular function, with meridians being extensions of those functional systems throughout the body.

''Qi''
''Qi'' is a polysemous
Polysemy ( or ; ) is the capacity for a sign (e.g. a symbol, morpheme, word, or phrase) to have multiple related meanings. For example, a word can have several word senses. Polysemy is distinct from '' monosemy'', where a word has a single meani ...
word that traditional Chinese medicine distinguishes as being able to transform into many different qualities of ''qi'' ( zh, s=气 , t=氣 , p=qì , labels=no). In a general sense, ''qi'' is something that is defined by five "cardinal functions":[. "" [Physiological functions of qi: 1.) Function of actuation ... 2.) Function of warming ... 3.) Function of defense ... 4.) Function of containment ... 5.) Function of transformation ...]]
# Actuation ( zh, t=推動 , s=推动 , p=tuīdòng , labels=no) – of all physical processes in the body, especially the circulation of all body fluids such as blood in their vessels. This includes actuation of the functions of the zang-fu organs and meridians.
# Warming ( zh, t=溫煦 , s=温煦 , p=wēnxù , labels=no) – the body, especially the limbs.
# Defense ( zh, c=防御 , p=fángyù , labels=no) – against Exogenous Pathogenic Factors
# Containment ( zh, t=固攝 , s=固摄 , p=gùshè , labels=no) – of body fluids, i.e., keeping blood, sweat, urine, semen, etc. from leakage or excessive emission.
# Inter-transformationel ( zh, t=氣化 , s=气化 , p=qìhuà , labels=no) – of food, drink, and breath into ''qi'', xue (blood), and jinye ("fluids"), and/or transformation of all of the latter into each other.
A lack of ''qi'' will be characterized especially by pale complexion, lassitude of spirit, lack of strength, spontaneous sweating, laziness to speak, non-digestion of food, shortness of breath (especially on exertion), and a pale and enlarged tongue.
''Qi'' is believed to be partially generated from food and drink, and partially from air (by breathing). Another considerable part of it is inherited from the parents and will be consumed in the course of life.
TCM uses special terms for ''qi'' running inside of the blood vessels and for qi that is distributed in the skin, muscles, and tissues between them. The former is called ''yingqi'' ( zh, s=营气 , t=營氣 , p=yíngqì , labels=no); its function is to complement xuè and its nature has a strong yin aspect (although ''qi'' in general is considered to be yang). The latter is called ''weiqi'' ( zh, t=衛氣 , s=卫气 , p=weìqì , labels=no); its main function is defence and it has pronounced yang nature.
''Qi'' is said to circulate in the meridians. Just as the ''qi'' held by each of the zang-fu organs, this is considered to be part of the 'principal' ''qi'' of the body., also known as "true" ''qi'' ( zh, t=真氣 , s=真气 , p=zhēnqì , labels=no) or "original" ''qi'' ( zh, t=原氣 , s=原气 , p=yuánqì , labels=no).
Xie
In contrast to the majority of other functional entities, or (, "blood") is correlated with a physical form – the red liquid running in the blood vessels. Its concept is, nevertheless, defined by its functions: nourishing all parts and tissues of the body, safeguarding an adequate degree of moisture, and sustaining and soothing both consciousness and sleep.
Typical symptoms of a lack of (usually termed "blood vacuity" []) are described as: Pale-white or withered-yellow complexion, dizziness, flowery vision, palpitations, insomnia, numbness of the extremities; pale tongue; "fine" pulse.
''Jinye''
Closely related to xuě are the ''jinye'' ( zh, c=津液 , p=jīnyè , labels=no, usually translated as "body fluids"), and just like xuě they are considered to be yin in nature, and defined first and foremost by the functions of nurturing and moisturizing the different structures of the body. Their other functions are to harmonize yin and yang, and to help with the secretion of waste products.[" [3.)

To highlight the fact that they are not equivalent to anatomical organs, their names are usually capitalized.
The ''zangs essential functions consist in production and storage of ''qi'' and xuě; they are said to regulate digestion, breathing, water metabolism, the musculoskeletal system, the skin, the sense organs, aging, emotional processes, and mental activity, among other structures and processes. The fǔ organs' main purpose is merely to transmit and digest ()[" [The Six Fu: gallbladder, stomach, small intestine, large intestine, bladder, sanjiao; "transmit and digest"] as seen at ] substances such as waste and food.
Since their concept was developed on the basis of Wǔ Xíng philosophy, each zàng is paired with a fǔ, and each zàng-fǔ pair is assigned to one of five elemental qualities (i.e., the Five Elements or Five Phases). These correspondences are stipulated as:

in modern medicine). However, there are few or no ancient works on it except for Fu Qingzhu's ''Fu Qingzhu Nu Ke'' (Fu Qingzhu's ''Gynecology''). In traditional China, as in many other cultures, the health and medicine of female bodies was less understood than that of male bodies. Women's bodies were often secondary to male bodies, since women were thought of as the weaker, sicklier sex.[Furth, Charlotte. ''A Flourishing Yin: Gender in China's Medical History, 960–1665''. Berkeley: University of California Press, 1999]
hdl.handle.net
In clinical encounters, women and men were treated differently. Diagnosing women was not as simple as diagnosing men. First, when a woman fell ill, an appropriate adult man was to call the doctor and remain present during the examination, for the woman could not be left alone with the male doctor. The physician would discuss the female's problems and diagnosis only through the male. However, in certain cases, when a woman dealt with complications of pregnancy or birth, older women assumed the role of the formal authority. Men in these situations would not have much power to interfere. Second, women were often silent about their issues with doctors due to the societal expectation of female modesty when a male figure was in the room. Third, patriarchal society also caused doctors to call women and children patients "the anonymous category of family members (''Jia Ren'') or household (''Ju Jia'')" in their journals. This anonymity and lack of conversation between the doctor and woman patient led to the inquiry diagnosis of the Four Diagnostic Methods being the most challenging. Doctors used a medical doll known as a Doctor's lady, on which female patients could indicate the location of their symptoms.
Cheng Maoxian (b. 1581), who practiced medicine in Yangzhou, described the difficulties doctors had with the norm of female modesty. One of his case studies was that of Fan Jisuo's teenage daughter, who could not be diagnosed because she was unwilling to speak about her symptoms, since the illness involved discharge from her intimate areas. As Cheng describes, there were four standard methods of diagnosis – looking, asking, listening and smelling and touching (for pulse-taking). To maintain some form of modesty, women would often stay hidden behind curtains and screens. The doctor was allowed to touch enough of her body to complete his examination, often just the pulse taking. This would lead to situations where the symptoms and the doctor's diagnosis did not agree and the doctor would have to ask to view more of the patient.
These social and cultural beliefs were often barriers to learning more about female health, with women themselves often being the most formidable barrier. Women were often uncomfortable talking about their illnesses, especially in front of the male chaperones that attended medical examinations. Women would choose to omit certain symptoms as a means of upholding their chastity and honor. One such example is the case in which a teenage girl was unable to be diagnosed because she failed to mention her symptom of vaginal discharge. Silence was their way of maintaining control in these situations, but it often came at the expense of their health and the advancement of female health and medicine. This silence and control were most obviously seen when the health problem was related to the core of Ming ''fuke'', or the sexual body. It was often in these diagnostic settings that women would choose silence. In addition, there would be a conflict between patient and doctor on the probability of her diagnosis. For example, a woman who thought herself to be past the point of child-bearing age, might not believe a doctor who diagnoses her as pregnant. This only resulted in more conflict.
Yin yang and gender
Yin and yang were critical to the understanding of women's bodies, but understood only in conjunction with male bodies. Yin and yang ruled the body, the body being a microcosm of the universe and the earth. In addition, gender in the body was understood as homologous, the two genders operating in synchronization. Gender was presumed to influence the movement of energy and a well-trained physician would be expected to read the pulse and be able to identify two dozen or more energy flows. Yin and yang concepts were applied to the feminine and masculine aspects of all bodies, implying that the differences between men and women begin at the level of this energy flow. According to ''Bequeathed Writings of Master Chu'' the male's yang pulse movement follows an ascending path in "compliance ith cosmic directionso that the cycle of circulation in the body and the Vital Gate are felt...The female's yin pulse movement follows a defending path against the direction of cosmic influences, so that the nadir and the Gate of Life are felt at the inch position of the left hand". In sum, classical medicine marked yin and yang as high and low on bodies which in turn would be labeled normal or abnormal and gendered either male or female.
Bodily functions could be categorized through systems, not organs. In many drawings and diagrams, the twelve channels and their visceral systems were organized by yin and yang, an organization that was identical in female and male bodies. Female and male bodies were no different on the plane of yin and yang. Their gendered differences were not acknowledged in diagrams of the human body. Medical texts such as the '' Yuzuan yizong jinjian'' were filled with illustrations of male bodies or androgynous bodies that did not display gendered characteristics.[Wu, Yi-Li, and . "The Gendered Medical Iconography of the Golden Mirror, Yuzuan Yizong Jinjian , 1742." In ''Imagining Chinese Medicine'', edited by Lo Vivienne, , Barrett Penelope, Dear David, Di Lu, , Reynolds Lois, Yang Dolly, and , 111–32. Leiden; Boston: Brill, 2018. .]
As in other cultures, fertility and menstruation dominate female health concerns. Since male and female bodies were governed by the same forces, traditional Chinese medicine did not recognize the womb as the place of reproduction. The abdominal cavity presented pathologies that were similar in both men and women, which included tumors, growths, hernias, and swellings of the genitals. The "master system", as Charlotte Furth calls it, is the kidney visceral system, which governed reproductive functions. Therefore, it was not the anatomical structures that allowed for pregnancy, but the difference in processes that allowed for the condition of pregnancy to occur.
Pregnancy
Traditional Chinese medicine's dealings with pregnancy are documented from at least the seventeenth century. According to Charlotte Furth, "a pregnancy (in the seventeenth century) as a known bodily experience emerged ..out of the liminality of menstrual irregularity, as uneasy digestion, and a sense of fullness". These symptoms were common among other illness as well, so the diagnosis of pregnancy often came late in the term. The ''Canon of the Pulse'', which described the use of pulse in diagnosis, stated that pregnancy was "a condition marked by symptoms of the disorder in one whose pulse is normal" or "where the pulse and symptoms do not agree". Women were often silent about suspected pregnancy, which led to many men not knowing that their wife or daughter was pregnant until complications arrived. Complications through the misdiagnosis and the woman's reluctance to speak often led to medically induced abortions. Cheng, Furth wrote, "was unapologetic about endangering a fetus when pregnancy risked a mother's well being". The method of abortion was the ingestion of certain herbs and foods. Disappointment at the loss of the fetus often led to family discord.
Postpartum
If the baby and mother survived the term of the pregnancy, childbirth was then the next step. The tools provided for birth were: towels to catch the blood, a container for the placenta, a pregnancy sash to support the belly, and an infant swaddling wrap. With these tools, the baby was born, cleaned, and swaddled; however, the mother was then immediately the focus of the doctor to replenish her ''qi''. In his writings, Cheng places a large amount of emphasis on the Four Diagnostic methods to deal with postpartum issues and instructs all physicians to "not neglect any f the four methods. The process of birthing was thought to deplete a woman's blood level and ''qi'' so the most common treatments for postpartum were food (commonly garlic and ginseng), medicine, and rest.[Cheng Maoxian. ''Yi'an'' (casebook). Dated 1633, but Xue Qinghu (1991) states that the original was printed in 1644] This process was followed up by a month check-in with the physician, a practice known as ''zuo yuezi''.
Infertility
Infertility, not very well understood, posed serious social and cultural repercussions. The seventh-century scholar Sun Simiao is often quoted: "those who have prescriptions for women's distinctiveness take their differences of pregnancy, childbirth and nternalbursting injuries as their basis." Even in contemporary ''fuke'' placing emphasis on reproductive functions, rather than the entire health of the woman, suggests that the main function of ''fuke'' is to produce children.
Once again, the kidney visceral system governs the "source ''Qi''", which governs the reproductive systems in both sexes. This source ''Qi'' was thought to "be slowly depleted through sexual activity, menstruation and childbirth." It was also understood that the depletion of source Qi could result from the movement of an external pathology that moved through the outer visceral systems before causing more permanent damage to the home of source Qi, the kidney system. In addition, the view that only very serious ailments ended in the damage of this system means that those who had trouble with their reproductive systems or fertility were seriously ill.
According to traditional Chinese medical texts, infertility can be summarized into different syndrome types. These were spleen and kidney depletion (yang depletion), liver and kidney depletion (yin depletion), blood depletion, phlegm damp, liver oppression, and damp heat. This is important because, while most other issues were complex in Chinese medical physiology, women's fertility issues were simple. Most syndrome types revolved around menstruation, or lack thereof. The patient was entrusted with recording not only the frequency, but also the "volume, color, consistency, and odor of menstrual flow." This placed responsibility of symptom recording on the patient, and was compounded by the earlier discussed issue of female chastity and honor. This meant that diagnosing female infertility was difficult, because the only symptoms that were recorded and monitored by the physician were the pulse and color of the tongue.
Concept of disease
In general, disease is perceived as a disharmony (or imbalance) in the functions or interactions of yin, yang, qi, xuĕ, zàng-fǔ, meridians etc. and/or of the interaction between the human body and the environment. Therapy is based on which "pattern of disharmony" can be identified. Thus, "pattern discrimination" is the most important step in TCM diagnosis. It is also known to be the most difficult aspect of practicing TCM.
To determine which pattern is at hand, practitioners will examine things like the color and shape of the tongue, the relative strength of pulse-points, the smell of the breath, the quality of breathing or the sound of the voice.["Tongue Diagnosis in Chinese Medicine", Giovanni Maciocia, Eastland Press; Revised edition (June 1995)] For example, depending on tongue and pulse conditions, a TCM practitioner might diagnose bleeding from the mouth and nose as: "Liver fire rushes upwards and scorches the Lung, injuring the blood vessels and giving rise to reckless pouring of blood from the mouth and nose." He might then go on to prescribe treatments designed to clear heat or supplement the Lung.
Disease entities
In TCM, a disease has two aspects: "bìng" and "zhèng".[Clavey, Steven (1995)]
"Fluid physiology and pathology in traditional Chinese medicine"
Elsevier. 2nd edition, 2003. The former is often translated as "disease entity", "disease category", "illness", or simply "diagnosis". The latter, and more important one, is usually translated as "pattern" (or sometimes also as "syndrome"). For example, the disease entity of a common cold might present with a pattern of wind-cold in one person, and with the pattern of wind-heat in another.
From a scientific point of view, most of the disease entities () listed by TCM constitute symptoms. Examples include headache, cough, abdominal pain, constipation etc.
Since therapy will not be chosen according to the disease entity but according to the pattern, two people with the same disease entity but different patterns will receive different therapy. Vice versa, people with similar patterns might receive similar therapy even if their disease entities are different. This is called ''yì bìng tóng zhì, tóng bìng yì zhì'' ().
Patterns
In TCM, "pattern" () refers to a "pattern of disharmony" or "functional disturbance" within the functional entities of which the TCM model of the body is composed. There are disharmony patterns of qi, xuě, the body fluids, the zàng-fǔ, and the meridians. They are ultimately defined by their symptoms and signs (i.e., for example, pulse and tongue findings).
In clinical practice, the identified pattern usually involves a combination of affected entities[Flaws, Bob (1990)]
"Sticking to the Point"
Blue Poppy Press. 10th Printing, 2007. (compare with typical examples of patterns). The concrete pattern identified should account for ''all'' the symptoms a person has.[Flaws, B. & Finney, D. (1996)]

Six Excesses
The Six Excesses (, sometimes also translated as "Pathogenic Factors",[ p. 159] or "Six Pernicious Influences"; with the alternative term of , – "Six Evils" or "Six Devils") are allegorical terms used to describe disharmony patterns displaying certain typical symptoms. These symptoms resemble the effects of six climatic factors. In the allegory, these symptoms can occur because one or more of those climatic factors (called , "the six qi") were able to invade the body surface and to proceed to the interior. This is sometimes used to draw causal relationships (i.e., prior exposure to wind/cold/etc. is identified as the cause of a disease), while other authors explicitly deny a direct cause-effect relationship between weather conditions and disease, pointing out that the Six Excesses are primarily descriptions of a certain combination of symptoms translated into a pattern of disharmony. It is undisputed, though, that the Six Excesses can manifest inside the body without an external cause. In this case, they might be denoted "internal", e.g., "internal wind" or "internal fire (or heat)".
The Six Excesses and their characteristic clinical signs are:
# Wind (): rapid onset of symptoms, wandering location of symptoms, itching, nasal congestion, "floating" pulse; tremor, paralysis, convulsion.
# Cold (): cold sensations, aversion to cold, relief of symptoms by warmth, watery/clear excreta, severe pain, abdominal pain, contracture/hypertonicity of muscles, (slimy) white tongue fur, "deep"/"hidden" or "string-like" pulse, or slow pulse.
# Fire/Heat (): aversion to heat, high fever, thirst, concentrated urine, red face, red tongue, yellow tongue fur, rapid pulse. (Fire and heat are basically seen to be the same)
# Dampness (): sensation of heaviness, sensation of fullness, symptoms of Spleen dysfunction, greasy tongue fur, "slippery" pulse.
# Dryness (): dry cough, dry mouth, dry throat, dry lips, nosebleeds, dry skin, dry stools.
# Summerheat (): either heat or mixed damp-heat symptoms.
Six-Excesses-patterns can consist of only one or a combination of Excesses (e.g., wind-cold, wind-damp-heat). They can also transform from one into another.
Typical examples of patterns
For each of the functional entities (qi, xuĕ, zàng-fǔ, meridians etc.), typical disharmony patterns are recognized; for example: qi vacuity and qi stagnation in the case of qi; blood vacuity, blood stasis, and blood heat in the case of xuĕ; Spleen qi vacuity, Spleen yang vacuity, Spleen qi vacuity with down-bearing qi, Spleen qi vacuity with lack of blood containment, cold-damp invasion of the Spleen, damp-heat invasion of Spleen and Stomach in case of the Spleen zàng; wind/cold/damp invasion in the case of the meridians.
TCM gives detailed prescriptions of these patterns regarding their typical symptoms, mostly including characteristic tongue and/or pulse findings. For example:
* "Upflaming Liver fire" (): Headache, red face, reddened eyes, dry mouth, nosebleeds, constipation, dry or hard stools, profuse menstruation, sudden tinnitus
Tinnitus is a condition when a person hears a ringing sound or a different variety of sound when no corresponding external sound is present and other people cannot hear it. Nearly everyone experiences faint "normal tinnitus" in a completely ...
or deafness, vomiting of sour or bitter fluids, expectoration of blood, irascibility, impatience; red tongue with dry yellow fur; slippery and string-like pulse.
Eight principles of diagnosis
The process of determining which actual pattern is on hand is called (, usually translated as "pattern diagnosis", "pattern identification" or "pattern discrimination"). Generally, the first and most important step in pattern diagnosis is an evaluation of the present signs and symptoms on the basis of the "Eight Principles" (). These eight principles refer to four pairs of fundamental qualities of a disease: exterior/interior, heat/cold, vacuity/repletion, and yin/yang. Out of these, heat/cold and vacuity/repletion have the biggest clinical importance. The yin/yang quality, on the other side, has the smallest importance and is somewhat seen aside from the other three pairs, since it merely presents a general and vague conclusion regarding what other qualities are found. In detail, the Eight Principles refer to the following:
* ''Yin and yang'' are universal aspects all things can be classified under, this includes diseases in general as well as the Eight Principles' first three couples. For example, cold is identified to be a yin aspect, while heat is attributed to yang. Since descriptions of patterns in terms of yin and yang lack complexity and clinical practicality, though, patterns are usually not labeled this way anymore. Exceptions are vacuity-cold and repletion-heat patterns, who are sometimes referred to as "yin patterns" and "yang patterns" respectively.
* ''Exterior'' () refers to a disease manifesting in the superficial layers of the body – skin, hair, flesh, and meridians. It is characterized by aversion to cold and/or wind, headache, muscle ache, mild fever, a "floating" pulse, and a normal tongue appearance.
* ''Interior'' () refers to disease manifestation in the zàng-fǔ, or (in a wider sense) to any disease that can not be counted as exterior. There are no generalized characteristic symptoms of interior patterns, since they'll be determined by the affected zàng or fǔ entity.
* ''Cold'' () is generally characterized by aversion to cold, absence of thirst, and a white tongue fur. More detailed characterization depends on whether cold is coupled with vacuity or repletion.
* ''Heat'' () is characterized by an absence of aversion to cold, a red and painful throat, a dry tongue fur and a rapid and floating pulse if it falls together with an exterior pattern. In all other cases, symptoms depend on whether heat is coupled with vacuity or repletion.
* ''Deficiency'' (), can be further differentiated into deficiency of qi, xuě, yin and yang
Originating in Chinese philosophy, yin and yang (, ), also yinyang or yin-yang, is the concept of opposite cosmic principles or forces that interact, interconnect, and perpetuate each other. Yin and yang can be thought of as complementary an ...
, with all their respective characteristic symptoms. Yin deficiency can also cause "empty-heat".
* ''Excess'' () generally refers to any disease that cannot be identified as a deficient pattern, and usually indicates the presence of one of the Six Excesses, or a pattern of stagnation (of qi, xuě, etc.).[Tierra & Tierra 1998, p. 108] In a concurrent exterior pattern, excess is characterized by the absence of sweating.
After the fundamental nature of a disease in terms of the Eight Principles is determined, the investigation focuses on more specific aspects. By evaluating the present signs and symptoms against the background of typical disharmony patterns of the various entities, evidence is collected whether or how specific entities are affected. This evaluation can be done
# in respect of the meridians ()
# in respect of qi ()
# in respect of xuè ()
# in respect of the body fluids ()
# in respect of the zàng-fǔ () – very similar to this, though less specific, is disharmony pattern description in terms of the Five Elements [])
There are also three special pattern diagnosis systems used in case of febrile and infectious diseases only ("Six Channel system" or "six division pattern" []; "Wei Qi Ying Xue system" or "four division pattern" []; "San Jiao system" or "three burners pattern" []).
Considerations of disease causes
Although TCM and its concept of disease do not strongly differentiate between cause and effect,[Ross, Jeremy (1984]
"Zang Fu, the organ systems of traditional Chinese medicine"
Elsevier. First edition 1984. pattern discrimination can include considerations regarding the disease cause; this is called (, "disease-cause pattern discrimination").
There are three fundamental categories of disease causes () recognized:
# external causes: these include the Six Excesses and "Pestilential Qi".
# internal causes: the "Seven Affects" (, sometimes also translated as "Seven Emotions") – joy, anger, brooding, sorrow, fear, fright and grief. These are believed to be able to cause damage to the functions of the zàng-fú, especially of the Liver.
# non-external-non-internal causes: dietary irregularities (especially: too much raw, cold, spicy, fatty or sweet food; voracious eating; too much alcohol), fatigue, sexual intemperance, trauma, and parasites ().
Diagnostics
In TCM, there are five major diagnostic methods: inspection, auscultation, olfaction, inquiry, and palpation. These are grouped into what is known as the "Four pillars" of diagnosis, which are Inspection, Auscultation/ Olfaction, Inquiry, and Palpation ().
* Inspection focuses on the face and particularly on the tongue, including analysis of the tongue size, shape, tension, color and coating, and the absence or presence of teeth marks around the edge.
* Auscultation refers to listening for particular sounds (such as wheezing).
* Olfaction refers to attending to body odor.
* Inquiry focuses on the "seven inquiries", which involve asking the person about the regularity, severity, or other characteristics of: chills, fever, perspiration, appetite, thirst, taste, defecation, urination, pain, sleep, menses
Menstruation (also known as a period, among other colloquial terms) is the regular discharge of blood and Mucous membrane, mucosal tissue from the endometrium, inner lining of the uterus through the vagina. The menstrual cycle is characterized ...

.
* Palpation which includes feeling the body for tender A-shi points, and the palpation of the wrist pulses as well as various other pulses, and palpation of the abdomen.
Tongue and pulse
Examination of the tongue and the pulse are among the principal diagnostic methods in TCM. Details of the tongue, including shape, size, color, texture, cracks, teeth marks, as well as tongue coating are all considered as part of tongue diagnosis. Various regions of the tongue's surface are believed to correspond to the zàng-fŭ organs. For example, redness on the tip of the tongue might indicate heat in the Heart, while redness on the sides of the tongue might indicate heat in the Liver.
Pulse palpation involves measuring the pulse both at a superficial and at a deep level at three different locations on the radial artery
In human anatomy, the radial artery is the main artery of the lateral aspect of the forearm.
Structure
The radial artery arises from the bifurcation of the brachial artery in the antecubital fossa. It runs distally on the anterior part of the ...
(''Cun, Guan, Chi'', located two fingerbreadths from the wrist crease, one fingerbreadth from the wrist crease, and right at the wrist crease, respectively, usually palpated with the index, middle and ring finger) of each arm, for a total of twelve pulses, all of which are thought to correspond with certain zàng-fŭ. The pulse is examined for several characteristics including rhythm, strength and volume, and described with qualities like "floating, slippery, bolstering-like, feeble, thready and quick"; each of these qualities indicates certain disease patterns. Learning TCM pulse diagnosis can take several years.
Herbal medicine
The term "herbal medicine" is somewhat misleading in that, while plant elements are by far the most commonly used substances in TCM, other, non-botanic substances are used as well: animal, human, fungi, and mineral products are also used. Thus, the term "medicinal" (instead of herb) may be used. A 2019 review of traditional herbal treatments found they are widely used but lacking in scientific evidence, and urged a more rigorous approach by which genuinely useful medicinals might be identified.
Raw materials
There are roughly 13,000 compounds used in China and over 100,000 TCM recipes recorded in the ancient literature. Plant elements and extracts are by far the most common elements used.[Foster, S. & Yue, C. (1992)]

Since TCM recognizes bear bile as a treatment compound, more than 12,000 asiatic black bears are held in bear farms. The bile is extracted through a permanent hole in the abdomen leading to the gall bladder, which can cause severe pain. This can lead to bears trying to kill themselves. As of 2012, approximately 10,000 bears are farmed in China for their bile. This practice has spurred public outcry across the country. The bile is collected from live bears via a surgical procedure. As of March 2020 bear bile as ingredient of ''Tan Re Qing'' injection remains on the list of remedies recommended for treatment of "severe cases" of COVID-19 by National Health Commission of China and the National Administration of Traditional Chinese Medicine.

Traditional categorization
The traditional categorizations and classifications that can still be found today are:
* The classification according to the Four Natures (): hot, warm, cool, or cold (or, neutral in terms of temperature) and hot and warm herbs are used to treat cold
Cold is the presence of low temperature, especially in the atmosphere. In common usage, cold is often a subjectivity, subjective perception. A lower bound to temperature is absolute zero, defined as 0.00K on the Kelvin scale, an absolute t ...
diseases, while cool and cold herbs are used to treat heat diseases.
* The classification according to the Five Flavors, (, sometimes also translated as Five Tastes): acrid, sweet, bitter, sour, and salty. Substances may also have more than one flavor, or none (i.e., a "bland" flavor). Each of the Five Flavors corresponds to one of zàng organs, which in turn corresponds to one of the Five Phases
( zh, c=五行, p=wǔxíng), usually translated as Five Phases or Five Agents, is a fivefold conceptual scheme used in many traditional Chinese fields of study to explain a wide array of phenomena, including terrestrial and celestial rela ...
. A flavor implies certain properties and therapeutic actions of a substance; e.g., saltiness drains downward and softens hard masses, while sweetness is supplementing, harmonizing, and moistening.
* The classification according to the meridian – more precisely, the zàng-fu organ including its associated meridian – which can be expected to be primarily affected by a given compound.
* The categorization according to the specific function mainly include: exterior-releasing or exterior-resolving, heat-clearing, downward-draining, or precipitating wind-damp-dispelling, dampness-transforming, promoting the movement of water and percolating dampness or dampness-percolating, interior-warming, qi-regulating or qi-rectifying, dispersing food accumulation or food-dispersing, worm-expelling, stopping bleeding or blood- stanching, quickening the Blood and dispelling stasis or blood-quickening, transforming phlegm, stopping coughing and calming wheezing or phlegm-transforming and cough- and panting-suppressing, Spirit-quieting, calming the liver and expelling wind or liver-calming and wind-extinguishing orifice-opening supplementing which includes qi-supplementing, blood-nourishing, yin-enriching, and yang-fortifying, astriction-promoting or securing and astringing, vomiting-inducing, and substances for external application.[Xu, L. & Wang, W.

there were not enough good-quality trials of herbal therapies to allow their effectiveness to be determined. A high percentage of relevant studies on traditional Chinese medicine are in Chinese databases. Fifty percent of systematic reviews on TCM did not search Chinese databases, which could lead to a bias in the results. Many systematic reviews of TCM interventions published in Chinese journals are incomplete, some contained errors or were misleading.

Drug research
With an eye to the enormous Chinese market, pharmaceutical companies have explored creating new drugs from traditional remedies. The journal ''Nature'' commented that "claims made on behalf of an uncharted body of knowledge should be treated with the customary scepticism that is the bedrock of both science and medicine."
There was success in the 1970s, however, with the development of the antimalarial drug artemisinin

Safety
From the earliest records regarding the use of compounds to today, the toxicity of certain substances has been described in all Chinese materiae medicae. Since TCM has become more popular in the Western world, there are increasing concerns about the potential toxicity of many traditional Chinese plants, animal parts and minerals. Traditional Chinese herbal remedies are conveniently available from grocery stores in most Chinese neighborhoods; some of these items may contain toxic ingredients, are imported into the U.S. illegally, and are associated with claims of therapeutic benefit without evidence. For most compounds, efficacy and toxicity testing are based on traditional knowledge rather than laboratory analysis. The toxicity in some cases could be confirmed by modern research (i.e., in scorpion); in some cases it could not (i.e., in '' Curculigo''). Traditional herbal medicines can contain extremely toxic chemicals and heavy metals, and naturally occurring toxins, which can cause illness, exacerbate pre-existing poor health or result in death. Botanical misidentification of plants can cause toxic reactions in humans. The description of some plants used in TCM has changed, leading to unintended poisoning by using the wrong plants. A concern is also contaminated herbal medicines with microorganisms and fungal toxins, including aflatoxin

Acupuncture and moxibustion
Acupuncture is the insertion of needles into superficial structures of the body (skin, subcutaneous tissue, muscles) – usually at acupuncture points (acupoints) – and their subsequent manipulation; this aims at influencing the flow of qi. According to TCM it relieves pain
Pain is a distressing feeling often caused by intense or damaging Stimulus (physiology), stimuli. The International Association for the Study of Pain defines pain as "an unpleasant sense, sensory and emotional experience associated with, or res ...

Acupuncture is often accompanied by moxibustion – the Chinese characters for acupuncture () literally meaning "acupuncture-moxibustion" – which involves burning mugwort
Mugwort is a common name for several species of aromatic flowering plants in the genus '' Artemisia.'' In Europe, mugwort most often refers to the species '' Artemisia vulgaris'', or common mugwort. In East Asia the species '' Artemisia argyi'' ...

History
The society w ...
, "available scientific evidence does not support claims that moxibustion is effective in preventing or treating cancer or any other disease".
In electroacupuncture, an electric current is applied to the needles once they are inserted, to further stimulate the respective acupuncture points.
A recent historian of Chinese medicine remarked that it is "nicely ironic that the specialty of acupuncture – arguably the most questionable part of their medical heritage for most Chinese at the start of the twentieth century – has become the most marketable aspect of Chinese medicine." She found that acupuncture as we know it today has hardly been in existence for sixty years. Moreover, the fine, filiform needle we think of as the acupuncture needle today was not widely used a century ago. Present day acupuncture was developed in the 1930s and put into wide practice only as late as the 1960s.
Efficacy
A 2013 editorial in the American journal '' Anesthesia and Analgesia'' stated that acupuncture studies produced inconsistent results, (i.e. acupuncture relieved pain in some conditions but had no effect in other very similar conditions) which suggests the presence of false positive results. These may be caused by factors like biased study design, poor blinding, and the classification of electrified needles (a type of TENS) as a form of acupuncture. The inability to find consistent results despite more than 3,000 studies, the editorial continued, suggests that the treatment seems to be a placebo effect
A placebo ( ) can be roughly defined as a sham medical treatment. Common placebos include inert tablets (like sugar pills), inert injections (like saline), sham surgery, and other procedures.
Placebos are used in randomized clinical trials ...
and the existing equivocal positive results are the type of noise

one expects to see after a large number of studies are performed on an inert therapy. The editorial concluded that the best controlled studies showed a clear pattern, in which the outcome does not rely upon needle location or even needle insertion, and since "these variables are those that define acupuncture, the only sensible conclusion is that acupuncture does not work."
According to the US NIH National Cancer Institute, a review of 17,922 patients reported that real acupuncture relieved muscle and joint pain, caused by aromatase inhibitors, much better than sham acupuncture. Regarding cancer patients, the review hypothesized that acupuncture may cause physical responses in nerve cells, the pituitary gland, and the brain – releasing proteins, hormones, and chemicals that are proposed to affect blood pressure, body temperature, immune activity, and endorphin release.

and David Colquhoun said the results were of negligible clinical significance.[ Reply to: ]
A 2011 overview of Cochrane reviews found evidence that suggests acupuncture is effective for some but not all kinds of pain. A 2010 systematic review found that there is evidence "that acupuncture provides a short-term clinically relevant effect when compared with a waiting list control or when acupuncture is added to another intervention" in the treatment of chronic low back pain. Two review articles discussing the effectiveness of acupuncture, from 2008 and 2009, have concluded that there is not enough evidence to conclude that it is effective beyond the placebo effect.

Tui na
Tui na () is a form of massage, based on the assumptions of TCM, from which shiatsu is thought to have evolved. Techniques employed may include thumb presses, rubbing, percussion, and assisted stretching.
''Qigong''
Qìgōng () is a TCM system of exercise and meditation that combines regulated breathing, slow movement, and focused awareness, purportedly to cultivate and balance qi. One branch of qigong is qigong massage, in which the practitioner combines massage techniques with awareness of the acupuncture channels and points.
''Qi'' is air, breath, energy, or primordial life source that is neither matter or spirit. While ''Gong'' is a skillful movement, work, or exercise of the ''qi''.

Other therapies
Cupping
Cupping () is a type of Chinese massage, consisting of placing several glass "cups" (open spheres) on the body. A match is lit and placed inside the cup and then removed before placing the cup against the skin. As the air in the cup is heated, it expands, and after placing in the skin, cools, creating lower pressure inside the cup that allows the cup to stick to the skin via suction
Suction is the day-to-day term for the movement of gases or liquids along a pressure gradient with the implication that the movement occurs because the lower pressure pulls the gas or liquid. However, the forces acting in this case do not orig ...
. When combined with massage oil, the cups can be slid around the back, offering "reverse-pressure massage".
Gua sha
Gua sha () is abrading the skin with pieces of smooth jade, bone, animal tusks or horns or smooth stones; until red spots then bruising cover the area to which it is done. It is believed that this treatment is for almost any ailment. The red spots and bruising take three to ten days to heal, there is often some soreness in the area that has been treated.
Die-da
Diē-dǎ () or Dit Da, is a traditional Chinese bone-setting technique, usually practiced by martial artists who know aspects of Chinese medicine that apply to the treatment of trauma and injuries such as bone fractures, sprains, and bruises. Some of these specialists may also use or recommend other disciplines of Chinese medical therapies if serious injury is involved. Such practice of bone-setting () is not common in the West.
Chinese food therapy
The concepts ''yin'' and ''yang'' are associated with different classes of foods, and tradition considers it important to consume them in a balanced fashion. However, there is no scientific evidence supporting such claims, nor their implied notions.
Regulations
Many governments have enacted laws to regulate TCM practice.
Australia
From 1 July 2012 Chinese medicine practitioners must be registered under the national registration and accreditation scheme with the Chinese Medicine Board of Australia and meet the Board's Registration Standards, to practice in Australia.
Canada
TCM is regulated in five provinces in Canada: Alberta, British Columbia, Ontario, Quebec, and Newfoundland & Labrador.

was created in 1949, which then absorbed existing TCM management in 1986 with major changes in 1998.
China's National People's Congress Standing Committee passed the country's first law on TCM in 2016, which came into effect on 1 July 2017. The new law standardized TCM certifications by requiring TCM practitioners to (i) pass exams administered by provincial-level TCM authorities, and (ii) obtain recommendations from two certified practitioners. TCM products and services can be advertised only with approval from the local TCM authority.
Ready-to-use TCM preparations, also known as Chinese patent medicines, are regulated by the National Medical Products Administration (and its predecessor CFDA) similar to preparations used in modern medicine since 1984. The barrier for entry, however, is much lower than medications based on modern/non-TCM principles; the rules allow for omitting clinical testing in a variety of circumstances. As of 2025, the latest (2020) rules allow a simplified procedure for preparations derived from an approved list of "classic prescriptions".
The government-run healthcare system covers a number of TCM procedures and preparations. In 2021, a total of 7114.5 billion yuan went into healthcare, amounting for 6.59% of the year's national GDP. Of these, 1111.5 billion yuan went into covering costs associated with TCM preparations (0.97% of national GDP), with 592.4 billion yuan covering the actual medications.

government seldom interfered in the affairs of Chinese society, including with regard to regulations on the practice of TCM. There were a few TCM pharmacies in Macau during the colonial period. In 1994, the Portuguese Macau government published Decree-Law no. 53/94/M that officially started to regulate the TCM market. After the sovereign handover, the Macau S.A.R. government also published regulations on the practice of TCM. In 2000, Macau University of Science and Technology and Nanjing University of Traditional Chinese Medicine established the Macau College of Traditional Chinese Medicine to offer a degree course in Chinese medicine.
In 2022, a new law regulating TCM, Law no. 11/2021, came into effect. The same law also repealed Decree-Law no. 53/94/M.
Indonesia
All traditional medicines, including TCM, are regulated by Indonesian Minister of Health Regulation of 2013 on traditional medicine. Traditional medicine license (''Surat Izin Pengobatan Tradisional'' – SIPT) is granted to the practitioners whose methods are recognized as safe and may benefit health. The TCM clinics are registered but there is no explicit regulation for it. The only TCM method which is accepted by medical logic and is empirically proofed is acupuncture.[Cheta Nilawaty dan Rini Kustiati. 13 August 2012. TEMPO]

Japan
Under modern Japanese medical law, it is possible for doctors to perform acupuncture and massage, but because there is a separate law regarding acupuncture and massage, these treatments are mainly performed by massage therapists, acupuncturists, and moxibustion practitioners.
Korea
Under the Medical Service Act (), an oriental medical doctor, whose obligation is to administer oriental medical treatment and provide guidance for health based on oriental medicine, shall be treated in the same manner as a medical doctor or dentist.
The Korea Institute of Oriental Medicine is the top research center of TCM in Korea.
Malaysia
The Traditional and Complementary Medicine Bill was passed by parliament in 2012 establishing the Traditional and Complementary Medicine Council to register and regulate traditional and complementary medicine practitioners, including TCM practitioners as well as other traditional and complementary medicine practitioners such as those in traditional Malay medicine and traditional Indian medicine.
