Simple (pharmacology)
A herbal is a book containing the names and descriptions of plants, usually with information on their medicinal, Herbal tonic, tonic, culinary, toxic, hallucinatory, aromatic, or Magic (paranormal), magical powers, and the legends associated with them.Arber, p. 14. A herbal may also classify the plants it describes, may give recipes for Extract, herbal extracts, tinctures, or potions, and sometimes include mineral and animal medicaments in addition to those obtained from plants. Herbals were often illustrated to assist plant identification.Anderson, p. 2. Herbals were among the first literature produced in Ancient Egypt, China, India, and Europe as the medical wisdom of the day accumulated by Herbalism, herbalists, apothecary, apothecaries and physicians. Herbals were also among the first books to be printed in both China and Europe. In Western Europe herbals flourished for two centuries following the introduction of moveable type (c. 1470–1670). In the late 17th century, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dioscorides De Materia Medica Byzantium 15th Century
Pedanius Dioscorides (, ; 40–90 AD), "the father of pharmacognosy", was a Greek physician, pharmacologist, botanist, and author of (in the original , , both meaning "On Medical Material") , a 5-volume Greek encyclopedic pharmacopeia on herbal medicine and related medicinal substances, that was widely read for more than 1,500 years. For almost two millennia Dioscorides was regarded as the most prominent writer on plants and plant drugs. Life A native of Anazarbus, Cilicia, Asia Minor, Dioscorides likely studied medicine nearby at the school in Tarsus, which had a pharmacological emphasis, and he dedicated his medical books to Laecanius Arius, a medical practitioner there. Though he writes he lived a "soldier's life" or "soldier-like life", his pharmacopeia refers almost solely to plants found in the Greek-speaking eastern Mediterranean, making it likely that he served in campaigns, or travelled in a civilian capacity, less widely as supposed. The name Pedanius is Roman, su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herbalism
Herbal medicine (also called herbalism, phytomedicine or phytotherapy) is the study of pharmacognosy and the use of medicinal plants, which are a basis of traditional medicine. Scientific evidence for the effectiveness of many herbal treatments remains limited, prompting ongoing regulatory evaluation and research into their safety and efficacy. Standards for purity or dosage are generally not provided. The scope of herbal medicine sometimes includes fungi, fungal and bee products, as well as Dietary mineral, minerals, Exoskeleton, shells and certain animal parts. Paraherbalism is the Pseudoscience, pseudoscientific use of plant or animal extracts as medicine, relying on unproven beliefs about the safety and effectiveness of minimally processed natural substances. Herbal medicine has been used since at least the Paleolithic era, with written records from ancient Sumer, Egypt, Greece, China, and India documenting its development and application over millennia.

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] |
Aromatherapy
Aromatherapy is a practice based on the use of aromatic materials, including essential oils and other aroma compounds, with claims for improving psychological well-being. It is used as a complementary therapy or as a form of alternative medicine, and typically is used via inhalation and not by ingestion. Fragrances used in aromatherapy are not approved as prescription drugs in the United States. Although there is insufficient medical evidence that aromatherapy can prevent, treat or cure any disease, aromatherapy is used by some people with diseases, such as cancer, to provide general well-being and relief from pain, nausea or stress. People may use blends of essential oils as a topical application, massage, inhalation, or water immersion. Essential oils comprise hundreds to thousands of aromatic constituents, like terpinoids and phenylpropanoids, and to sufficiently research the pharmacological effects of essential oil constituents, each isolated constituent in the sele ...

Homeopathy
Homeopathy or homoeopathy is a pseudoscientific system of alternative medicine. It was conceived in 1796 by the German physician Samuel Hahnemann. Its practitioners, called homeopaths or homeopathic physicians, believe that a substance that causes symptoms of a disease in healthy people can cure similar symptoms in sick people; this doctrine is called ''similia similibus curentur'', or "like cures like". Homeopathic preparations are termed ''remedies'' and are made using homeopathic dilution. In this process, the selected substance is repeatedly diluted until the final product is chemically indistinguishable from the diluent. Often not even a single molecule of the original substance can be expected to remain in the product. Between each dilution homeopaths may hit and/or shake the product, claiming this makes the diluent "remember" the original substance after its removal. Practitioners claim that such preparations, upon oral intake, can treat or cure disease. All relevant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Western World
The Western world, also known as the West, primarily refers to various nations and state (polity), states in Western Europe, Northern America, and Australasia; with some debate as to whether those in Eastern Europe and Latin America also constitute the West. The Western world likewise is called the Occident () in contrast to the Eastern world known as the Orient (). Definitions of the "Western world" vary according to context and perspectives; the West is an evolving concept made up of cultural, political, and economic synergy among diverse groups of people, and not a rigid region with fixed borders and members. Some historians contend that a linear development of the West can be traced from Greco-Roman world, Ancient Greece and Rome, while others argue that such a projection constructs a false genealogy. A geographical concept of the West started to take shape in the 4th century CE when Constantine the Great, Constantine, the first Christian Roman emperor, divided the Roman Em ...

Biological Classification
In biology, taxonomy () is the scientific study of naming, defining ( circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa (singular: taxon), and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, having developed a ranked system known as Linnaean taxonomy for categorizing organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transformed into a system of modern biological classification intended to reflect the evolutionary relationships among organisms, ...

Flora (publication)
A Flora is a book or other work which describes the plant species occurring in an area or time period, often with the aim of allowing identification. The term is usually capitalized to distinguish it from the use of "flora" to mean the plants rather than their descriptions. Some classic and modern Floras are listed below. Traditionally Floras are books, but some are now published on CD-ROM or websites. The area that a Flora covers can be either geographically or politically defined. Floras usually require some specialist botanical knowledge to use with any effectiveness. A Flora often contains diagnostic keys. Often these are ''dichotomous'' keys, which require the user to repeatedly examine a plant, and decide which one of two alternatives given in the Flora best applies to the plant. Floras produced at a local or regional level rarely contain identification keys. Instead they aim to impart more detailed understanding of the local status and distribution of that area's plants. ...

Botany
Botany, also called plant science, is the branch of natural science and biology studying plants, especially Plant anatomy, their anatomy, Plant taxonomy, taxonomy, and Plant ecology, ecology. A botanist or plant scientist is a scientist who specialises in this field. "Plant" and "botany" may be defined more narrowly to include only land plants and their study, which is also known as phytology. Phytologists or botanists (in the strict sense) study approximately 410,000 species of Embryophyte, land plants, including some 391,000 species of vascular plants (of which approximately 369,000 are flowering plants) and approximately 20,000 bryophytes. Botany originated as history of herbalism#Prehistory, prehistoric herbalism to identify and later cultivate plants that were edible, poisonous, and medicinal, making it one of the first endeavours of human investigation. Medieval physic gardens, often attached to Monastery, monasteries, contained plants possibly having medicinal benefit. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pharmacology
Pharmacology is the science of drugs and medications, including a substance's origin, composition, pharmacokinetics, pharmacodynamics, therapeutic use, and toxicology. More specifically, it is the study of the interactions that occur between a living organism and chemicals that affect normal or abnormal biochemical function. If substances have medicinal properties, they are considered pharmaceuticals. The field encompasses drug composition and properties, functions, sources, synthesis and drug design, molecular and cellular mechanisms, organ/systems mechanisms, signal transduction/cellular communication, molecular diagnostics, interactions, chemical biology, therapy, and medical applications and antipathogenic capabilities. The two main areas of pharmacology are pharmacodynamics and pharmacokinetics. Pharmacodynamics studies the effects of a drug on biological systems, and pharmacokinetics studies the effects of biological systems on a drug. In broad terms, pharmacod ...

Toxicology
Toxicology is a scientific discipline, overlapping with biology, chemistry, pharmacology, and medicine, that involves the study of the adverse effects of chemical substances on living organisms and the practice of diagnosing and treating exposures to toxins and toxicants. The relationship between dose and its effects on the exposed organism is of high significance in toxicology. Factors that influence chemical toxicity include the dosage, duration of exposure (whether it is acute or chronic), route of exposure, species, age, sex, and environment. Toxicologists are experts on poisons and poisoning. There is a movement for evidence-based toxicology as part of the larger movement towards evidence-based practices. Toxicology is currently contributing to the field of cancer research, since some toxins can be used as drugs for killing tumor cells. One prime example of this is ribosome-inactivating proteins, tested in the treatment of leukemia. The word ''toxicology'' () ...
