Ashwagandha
''Withania somnifera'', known commonly as ashwagandha, is an evergreen shrub in the Solanaceae family that is native to the Middle East and North Africa, other African regions, southern Europe, and Indian subcontinent. Several other species in the genus '' Withania'' are morphologically similar. Common names include Indian ginseng and winter cherry. ''W. somnifera'' is a short shrub 35–75 cm tall with tomentose branches, dull green elliptic leaves up to 10–12 cm long, small green bell-shaped flowers, and orange-red ripe fruit. The Latin species name ''somnifera'' means “ sleep-inducing,” while the name ashwagandha combines the Sanskrit words for “horse” and “smell,” referring to the root’s strong horse-like odor. It is cultivated mainly in dry regions of India and nearby countries like Nepal, Sri Lanka, China, and Yemen, preferring dry, stony soil with sun to partial shade, and is propagated from seeds in early spring or greenwood cuttings later. It is affe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ayurveda
Ayurveda (; ) is an alternative medicine system with historical roots in the Indian subcontinent. It is heavily practised throughout India and Nepal, where as much as 80% of the population report using ayurveda. The theory and practice of ayurveda is pseudoscientific and toxic metals including lead and Mercury (element), mercury are used as ingredients in many ayurvedic medicines. Ayurveda therapies have varied and evolved over more than two millennia. Therapies include herbal medicines, Dieting#Detox, special diets, Meditation#Hinduism, meditation, yoga, massage, Laxative#Historical and health fraud uses, laxatives, Enema#Alternative medicine, enemas, and medical oils. Ayurvedic preparations are typically based on complex herbal compounds, minerals, and metal substances (perhaps under the influence of early Indian alchemy or ''rasashastra''). Ancient ayurveda texts also taught surgical techniques, including rhinoplasty, lithotomy, sutures, cataract surgery, and the extraction ...

Carl Linnaeus
Carl Linnaeus (23 May 1707 – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné,#Blunt, Blunt (2004), p. 171. was a Swedish biologist and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern Taxonomy (biology), taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was the son of a curate and was born in Råshult, in the countryside of Småland, southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alkaloid
Alkaloids are a broad class of natural product, naturally occurring organic compounds that contain at least one nitrogen atom. Some synthetic compounds of similar structure may also be termed alkaloids. Alkaloids are produced by a large variety of organisms including bacteria, fungus, fungi, Medicinal plant, plants, and animals. They can be purified from crude extracts of these organisms by acid-base extraction, or solvent extractions followed by silica-gel column chromatography. Alkaloids have a wide range of pharmacology, pharmacological activities including antimalarial medication, antimalarial (e.g. quinine), asthma, antiasthma (e.g. ephedrine), chemotherapy, anticancer (e.g. omacetaxine mepesuccinate, homoharringtonine), cholinomimetic (e.g. galantamine), vasodilation, vasodilatory (e.g. vincamine), Antiarrhythmic agent, antiarrhythmic (e.g. quinidine), analgesic (e.g. morphine), antibacterial (e.g. chelerythrine), and anti-diabetic, antihyperglycemic activities (e.g. berb ...

Panax Ginseng
''Panax ginseng'', ginseng, also known as Asian ginseng, Chinese ginseng or Korean ginseng, is a species of plant whose root is the original source of ginseng. It is a perennial plant that grows in the mountains of East Asia. It is mainly cultivated in China, Korea, Russia, and Japan. ''P. ginseng'' is an herbaceous perennial plant, 30–60 cm tall, with palmately compound leaves, serrated leaflets, a terminal umbel of 30–50 flowers, red round fruits, and kidney-shaped seeds. ''P. ginseng'' is primarily cultivated in Korea. While all Korea, South Korean ginseng is ''P. ginseng'', ginseng production in China encompasses both ''P. ginseng'' and South China ginseng (''Panax notoginseng''). It may cause side effects or interact with various medications and conditions. Names ''Panax ginseng'' is called ''Rénshēn'' ( or or ; ) in Mandarin Chinese, Mandarin (Chinese), ''Insam'' () in Korean language, Korean, ''Nhân Sâm'' in Vietnamese Language, Vietnamese and ''Ninjin'' () i ...

Ginsenoside
Ginsenosides or panaxosides are a class of natural product steroid glycosides and triterpene saponins. Compounds in this family are found almost exclusively in the plant genus ''Panax'' (ginseng), which has a long history of use in traditional medicine that has led to the study of pharmacological effects of ginseng compounds. As a class, ginsenosides exhibit a large variety of subtle and difficult-to-characterize biological effects when studied in isolation. Ginsenosides can be isolated from various parts of the plant, though typically from the roots, and can be purified by column chromatography. The chemical profiles of ''Panax'' species are distinct; although Asian ginseng, ''Panax ginseng'', has been most widely studied due to its use in traditional Chinese medicine, there are ginsenosides unique to American ginseng (''Panax quinquefolius'') and Japanese ginseng (''Panax japonicus''). Ginsenoside content also varies significantly due to environmental effects. The leaves and stem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Withanolide
Withanolides are a group of at least 300 naturally occurring steroids built on an ergostane skeleton. They occur as secondary metabolites primarily in genera of the Nightshade family, for example in the tomatillo. Structurally, withanolides consist of a steroid backbone bound to a lactone or one of its derivatives; they are produced via oxidation of steroids. It remains unknown to what end withanolides are produced; they may act as a deterrent for feeding insect larvae and other herbivores. Genera within the nightshade family that produce withanolides include: ''Datura'', ''Iochroma'', ''Lycium'', '' Nicandra'', ''Physalis'', '' Salpichroa'', ''Solanum'', '' Mandragora'', '' Withania'', and '' Jaborosa''. No withanolide has been discovered in ''Nicotiana'' to date. Examples Withaferin A, the first withanolide to be isolated, was found in winter cherry (''Withania somnifera'') and ''Acnistus arborescens''. Salpichrolides A, B and G (isolated from '' Salpichroa origanifo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phytochemical
Phytochemicals are naturally-occurring chemicals present in or extracted from plants. Some phytochemicals are nutrients for the plant, while others are metabolites produced to enhance plant survivability and reproduction. The fields of extracting phytochemicals for manufactured products or applying scientific methods to study phytochemical properties are called ''phytochemistry''. An individual who uses phytochemicals in food chemistry manufacturing or research is a ''phytochemist''. Phytochemicals without a nutrient definition have no confirmed biological activities or proven health benefits when consumed in plant foods. Once phytochemicals in a food enter the digestion process, the fate of individual phytochemicals in the body is unknown due to extensive metabolism of the food in the gastrointestinal tract, producing phytochemical metabolites with different biological properties from those of the parent compound that may have been tested in vitro. Further, the bioavaila ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Evidence-based Medicine
Evidence-based medicine (EBM) is "the conscientious, explicit and judicious use of current best evidence in making decisions about the care of individual patients. It means integrating individual clinical expertise with the best available external clinical evidence from systematic research." The aim of EBM is to integrate the experience of the clinician, the values of the patient, and the best available scientific information to guide decision-making about clinical management. The term was originally used to describe an approach to teaching the practice of medicine and improving decisions by individual physicians about individual patients. The EBM Pyramid is a tool that helps in visualizing the hierarchy of evidence in medicine, from least authoritative, like expert opinions, to most authoritative, like systematic reviews. Adoption of evidence-based medicine is necessary in a human Rights-based approach to development, rights-based approach to public health and a precondition ...

Extract
An extract (essence) is a substance made by extracting a part of a raw material, often by using a solvent such as ethanol, oil or water. Extracts may be sold as tinctures or absolutes or dried and powdered. The aromatic principles of many spices, nuts, herbs, fruits, etc., and some flowers, are marketed as extracts, among the best known of true extracts being almond, cinnamon, cloves, ginger, lemon, nutmeg, orange, peppermint, pistachio, rose, spearmint, vanilla, violet, rum, and wintergreen. Extraction techniques Most natural essences are obtained by extracting the essential oil from the feedstock, such as blossoms, fruit, and roots, or from intact plants through multiple techniques and methods: * Expression ( juicing, pressing) involves physical extraction material from feedstock, used when the oil is plentiful and easily obtained from materials such as citrus peels, olives, and grapes. * Absorption (steeping, decoction). Extraction is done by soak ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dietary Supplement
A dietary supplement is a manufactured product intended to supplement a person's diet by taking a pill (pharmacy), pill, capsule (pharmacy), capsule, tablet (pharmacy), tablet, powder, or liquid. A supplement can provide nutrients either extracted from food sources, or that are synthetic (to increase the quantity of their consumption). The classes of nutrient compounds in supplements include vitamins, Dietary mineral, minerals, Dietary fiber, fiber, fatty acids, and amino acids. Dietary supplements can also contain substances that have not been confirmed as being essential to life, and so are not ''nutrients'' per se, but are marketed as having a beneficial biological effect, such as plant pigments or polyphenols. Animals can also be a source of supplement ingredients, such as collagen from chickens or fish for example. These are also sold individually and in combination, and may be combined with nutrient ingredients. The European Commission has also established harmonize ...

Secondary Metabolite
Secondary metabolites, also called ''specialised metabolites'', ''secondary products'', or ''natural products'', are organic compounds produced by any lifeform, e.g. bacteria, archaea, fungi, animals, or plants, which are not directly involved in the normal cell growth, growth, Biological development, development, or reproduction of the organism. Instead, they generally mediate ecological biological interaction, interactions, which may produce a Natural selection, selective advantage for the organism by increasing its survivability or fecundity. Specific secondary metabolites are often restricted to a narrow set of species within a phylogenetic group. Secondary metabolites often play an important role in plant defense against herbivory and other interspecies defenses. Humans use secondary metabolites as medicines, flavourings, pigments, and recreational drugs. The term secondary metabolite was first coined by Albrecht Kossel, the 1910 Nobel Prize laureate for medicine and physio ...
