An aphrodisiac is a substance that increases sexual desire, sexual attraction, sexual pleasure, or sexual behavior. Substances range from a variety of plants, spices, foods, and synthetic chemicals. Natural aphrodisiacs like cannabis or cocaine are classified into plant-based and non-plant-based substances. There are non-naturally-occurring aphrodisiacs like MDMA and methamphetamine. Aphrodisiacs can be classified by their type of effects (i.e., psychological or physiological). Aphrodisiacs that contain hallucinogenic properties like Bufotenin have psychological effects on a person that can increase sexual desire and sexual pleasure. Aphrodisiacs that contain smooth muscle relaxing properties like yohimbine have physiological effects on a person that can affect hormone levels and increase blood flow. It is possible that the aphrodisiac effect of a substance is due to the placebo effect. Other substances that impede on areas that aphrodisiacs aim to enhance are classified as ana ...

Timbuktu Manuscripts
Timbuktu Manuscripts (or Tombouctou Manuscripts) is a blanket term for the large number of historically significant manuscripts that have been preserved for centuries in private households in Timbuktu, a city in northern Mali. The collections include manuscripts about art, medicine, philosophy, and science, as well as copies of the Quran. The number of manuscripts in the collections has been estimated as high as 700,000. The manuscripts are written in Arabic and local languages like Songhay and Tamasheq. The dates of the manuscripts range between the late 13th and the early 20th centuries (i.e., from the Islamisation of the Mali Empire until the decline of traditional education in French Sudan). Their subject matter ranges from scholarly works to short letters. After the decline of the Mali empire, the manuscripts were kept in the homes of Timbuktu locals, before research and digitisation efforts began in the 20th and 21st century. The manuscripts, and other cultural heritage i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horny Goat Weed
''Epimedium'', also known as barrenwort, bishop's hat, fairy wings, horny goat weed, or yin yang huo (), is a genus of flowering plants in the family (biology), family Berberidaceae. The majority of the species are endemic to China, with smaller numbers elsewhere in Asia, and a few in the Mediterranean region. ''Epimedium'' species are deciduous or evergreen Hardiness (plants), hardy perennials. The majority have four-parted "spider-like" flowers in spring. The species used as a dietary supplement is ''Epimedium grandiflorum''. It contains icariin, which is a weak PDE5 inhibitor ''in vitro''. Its clinical effects are unknown. There is little clinical evidence, but it is thought to have erectogenic properties and is found in some men's sexual health supplements. Description Species of ''Epimedium'' are herbaceous perennials, growing from an underground rhizome. Their growth habits are somewhat variable. Some have solitary stems, others have a "tufted" habit, with multiple ste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yohimbine
Yohimbine (), also known as quebrachine, is an indole alkaloid derived from the bark of the African tree ''Pausinystalia johimbe''; also from the bark of the unrelated South American tree ''Aspidosperma quebracho-blanco''. Yohimbine is an α2-adrenergic receptor antagonist, and has been used in a variety of research projects. It is a veterinary drug used to reverse sedation in dogs and deer. While yohimbine behaves as an aphrodisiac in some mammals, it does not do so in humans. It has been prescribed as a treatment for erectile dysfunction, although its reported clinical benefits were modest and it has largely been superseded by the PDE5 inhibitor class of drugs. Substances that have purported to be extracts from the yohimbe tree have been marketed as dietary supplements for various purposes, but they contain highly variable amounts of yohimbine, if any; no published scientific evidence supports their efficacy. Uses Yohimbine is a drug used in veterinary medicine to reverse th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ambrien
Ambergris ( or , la, ambra grisea, fro, ambre gris), ''ambergrease'', or grey amber is a solid, waxy, flammable substance of a dull grey or blackish colour produced in the digestive system of sperm whales. Freshly produced ambergris has a marine, fecal odor. It acquires a sweet, earthy scent as it ages, commonly likened to the fragrance of Isopropyl alcohol without the vaporous chemical astringency. Ambergris has been highly valued by perfume makers as a fixative that allows the scent to endure much longer, although it has been mostly replaced by synthetic ambroxide. Dogs are attracted to the smell of ambergris and are sometimes used by ambergris searchers. Etymology The word ''ambergris'' comes from the Old French "''ambre gris''" or "grey amber". The word "amber" comes from the same source, but it has been applied almost exclusively to fossilized tree resins from the Baltic region since the late 13th century in Europe. Furthermore, the word "amber" is derived from the Mid ... [...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". 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. Background, history and definition Medicine has a long history of scientific inquiry about the prevention, diagnosis, and treatment of human disease. The concept of a controlled clinical trial was first described in 1662 by Jan Baptist van Helmont in reference to the practice of bloodletting. Wrote Van Helmont: The first published report describing the conduct and results of a controlled clinical trial was by James Lind, a Scottish naval surgeon who conducted rese ...

Extract
An extract 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, absolutes or in powder form. 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 soaking material in a solvent, as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alcohol (drug)
Alcohol, sometimes referred to by the chemical name ''ethanol'', is a depressant, depressant drug that is the active ingredient in alcoholic drink, drinks such as beer, wine, and distilled spirits (hard liquor). It is one of the oldest and most commonly consumed recreational drugs, causing the characteristic effects of alcohol intoxication ("drunkenness"). Among other effects, alcohol produces happiness and euphoria, anxiolytic, decreased anxiety, increased sociability, sedation, impairment of cognitive, memory, motor control, motor, and sense, sensory function, and generalized depression of central nervous system (CNS) function. Ethanol is only one of several types of Alcohol (chemistry), alcohol, but it is the only type of alcohol that is found in alcoholic beverages or commonly used for recreational purposes; other alcohols such as methanol and isopropyl alcohol are significantly more toxicity, toxic.

Ginseng
Ginseng () is the root of plants in the genus ''Panax'', such as Korean ginseng ('' P. ginseng''), South China ginseng ('' P. notoginseng''), and American ginseng ('' P. quinquefolius''), typically characterized by the presence of ginsenosides and gintonin. Ginseng is most commonly used in the cuisines and medicines of China and Korea. Although ginseng has been used in traditional medicine over centuries, modern clinical research is inconclusive about its medical effectiveness. There is no substantial evidence that ginseng is effective for treating any medical condition, and in the United States, for example, its use has not been approved by the US Food and Drug Administration (FDA) as a prescription drug. Although ginseng is commonly sold as a dietary supplement, inconsistent manufacturing practices for supplements have led to analyses showing that ginseng products may be contaminated with toxic metals or unrelated filler compounds, and its excessive use may have adverse effec ...
