Strychnos Nux-vomica Bark
''Strychnos'' is a genus of flowering plants, belonging to the family Loganiaceae (sometimes Strychnaceae). The genus includes about 200 accepted species of trees and lianas. The genus is widely distributed around the world's tropics and is noted for the presence of poisonous indole alkaloids in the roots, stems and leaves of various species. Among these alkaloids are the well-known and virulent poisons strychnine and curare. Etymology The name ''strychnos'' was applied by Pliny the Elder in his ''Natural History'' to ''Solanum nigrum''. The word is derived from the Ancient Greek στρύχνον (''strúkhnon'') – "acrid", "bitter". The meaning of the word ''strychnos'' was not fixed in Ancient Greece, where it could designate a variety of different plants having in common the property of toxicity. Distribution The genus has a pantropical distribution. Taxonomy The genus is divided into 12 sections, though it is conceded that the sections do not reflect evolution of the g ...

Medicinal Plants
Medicinal plants, also called medicinal herbs, have been discovered and used in traditional medicine practices since prehistoric times. Plants synthesize hundreds of chemical compounds for various functions, including Plant defense against herbivory, defense and protection against insects, fungi, Plant disease resistance, diseases, against parasites and herbivorous mammals. The earliest historical records of herbs are found from the Sumerian civilization, where hundreds of medicinal plants including opium are listed on clay tablets, . The Ebers Papyrus from ancient Egypt, , describes over 850 plant medicines. The Greek physician Pedanius Dioscorides, Dioscorides, who worked in the Roman army, documented over 1000 recipes for medicines using over 600 medicinal plants in , ; this formed the basis of pharmacopoeias for some 1500 years. Drug research sometimes makes use of ethnobotany to search for pharmacologically active substances, and this approach has yielded hundreds of use ...

Alternative Medicine
Alternative medicine refers to practices that aim to achieve the healing effects of conventional medicine, but that typically lack biological plausibility, testability, repeatability, or supporting evidence of effectiveness. Such practices are generally not part of evidence-based medicine. Unlike modern medicine, which employs the scientific method to test plausible therapies by way of Guidelines for human subject research, responsible and ethical clinical trials, producing repeatable evidence of either effect or of no effect, alternative therapies reside outside of mainstream medicine and do not originate from using the scientific method, but instead rely on testimonials, anecdotes, religion, tradition, superstition, belief in supernatural "Energy (esotericism), energies", pseudoscience, fallacy, errors in reasoning, propaganda, fraud, or other unscientific sources. Frequently used terms for relevant practices are New Age medicine, wikt:pseudo-medicine, pseudo-medicine, unortho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

HPLC
High-performance liquid chromatography (HPLC), formerly referred to as high-pressure liquid chromatography, is a technique in analytical chemistry used to separate, identify, and quantify specific components in mixtures. The mixtures can originate from food, chemicals, pharmaceuticals, biological, environmental and agriculture, etc., which have been dissolved into liquid solutions. It relies on high pressure pumps, which deliver mixtures of various solvents, called the mobile phase, which flows through the system, collecting the sample mixture on the way, delivering it into a cylinder, called the column, filled with solid particles, made of adsorbent material, called the stationary phase. Each component in the sample interacts differently with the adsorbent material, causing different migration rates for each component. These different rates lead to separation as the species flow out of the column into a specific detector such as UV detectors. The output of the detector is ...

Traditional Medicine
Traditional medicine (also known as indigenous medicine or folk medicine) refers to the knowledge, skills, and practices rooted in the cultural beliefs of various societies, especially Indigenous groups, used for maintaining health and treating illness. In some Asia, Asian and Africa, African countries, up to 80% of people rely on traditional medicine for primary health care. Traditional medicine includes systems like Ayurveda, traditional Chinese medicine, and Unani medicine, Unani. The World Health Organization supports their integration, but warns of potential risks and calls for more research on their safety and effectiveness. The use of medicinal herbs spans over 5,000 years, beginning with ancient civilizations like the Sumer, Sumerians, Ancient Egypt, Egyptians, Indian people, Indians, and Chinese people, Chinese, evolving through Ancient Greece, Greek, Ancient Rome, Roman, Islam, Islamic, and Middle Ages, medieval European traditions, and continuing into Colonial histo ...

Unani Medicine
Unani or Yunani medicine (Urdu: ''tibb yūnānī'') is Perso-Arabic traditional medicine as practiced in Muslim culture in South Asia and modern day Central Asia. Unani medicine is pseudoscientific. The term '' Yūnānī'' means 'Greek', referring to the fact that the Perso-Arabic system of medicine was based on the teachings of the Greek physicians Hippocrates and Galen. The Hellenistic origin of Unani medicine is still visible in its being based on the classical four humours: phlegm (), blood (''dam''), yellow bile (''ṣafrā'') and black bile (''saudā), but it has also been influenced by Indian and Chinese traditional systems. History Arab and Persian elaborations upon the Greek system of medicine by figures like Ibn Sina and al-Razi influenced the early development of Unani. Unani medicine interacted with Indian Buddhist medicine at the time of Alexander's invasion of India. There was a great exchange of knowledge at that time which is visible from the simi ...

Commission E
The German ''Commission E'' is a scientific advisory board of the Federal Institute for Drugs and Medical Devices formed in 1978. The commission gives scientific expertise for the approval of substances and products previously used in traditional, folk and herbal medicine. The commission became known beyond Germany in the 1990s for compiling and publishing 380 monographs evaluating the safety and efficacy of herbs for licensed medical prescribing in Germany. The monographs were published between 1984 and 1994 in the '' Bundesanzeiger''; they have not been updated since then but are still considered valid. A summary of the publications is available on the website of the commission; unofficial copies of the monographs are available at the ''Heilpflanzen-Welt Bibliothek''. The monographs are a collection of official documents compiled over nearly two decades by a committee composed of twenty four scientific experts that was set up in 1978 to evaluate the safety and efficacy of herbal m ...

American Cancer Society
The American Cancer Society (ACS) is a nationwide non-profit organization dedicated to eliminating cancer. The ACS publishes the journals ''Cancer'', '' CA: A Cancer Journal for Clinicians'' and '' Cancer Cytopathology''. History The society was founded on May 22, 1913, by ten physicians and five businessmen in New York City under the name "American Society for the Control of Cancer" (ASCC). The current name was adopted in 1944. At the time of founding, it was not considered appropriate to mention the word "cancer" in public and information concerning this illness was cloaked in a climate of fear and denial. The top item on the founders' agenda was to raise awareness of cancer, before any other progress could be made in funding research. Therefore, a frenetic writing campaign was undertaken to educate doctors, nurses, patients and family members about cancer. Articles were written for popular magazines and professional journals. The ASCC undertook to publish their own journal, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
