Ipomoea Purga
''Ipomoea purga'' is a species of flowering plant in the genus ''Ipomoea''. It is commonly referred to as jalap and is probably also the source of the John the Conqueror root. Description ''Ipomoea purga'' is described as a vine that can reach heights of . When fresh, the root is black externally, white and milky within, and varies in size according to its age. It has heart shaped leaves and purple trumpet like flowers. ''Ipomoea purga'' is rather difficult to break down, but if triturated with cream of tartar, sugar of milk, or other hard salts, the process of pulverization is much easier, and the powder rendered much finer. When in powder form in order to ingest, the color is a pale grayish brown. ''Ipomoea purga'' is native to Mexico and it is naturalized in other parts of the neotropics. Discovery ''Ipomoea purga'' was encountered by Spanish conquistadores during the conquest of Mexico. It was introduced to Europe in 1565 as a medical herb used to treat an array of illnesse ...

Ipomoea
''Ipomoea'' () is the largest genus in the plant family Convolvulaceae, with over 600 species. It is a large and diverse group, with common names including morning glory, water convolvulus or water spinach, sweet potato, bindweed, moonflower, etc. The genus occurs throughout the tropical and subtropical regions of the world, and comprises annual and perennial herbaceous plants, lianas, shrubs, and small trees; most of the species are twining climbing plants. Their most widespread common name is morning glory, but some species in related genera bear that same common name and some ''Ipomoea'' species are known by different common names. Those formerly separated in ''Calonyction'' (Greek "good" and , , , "night") are called moonflowers. The name ''Ipomoea'' is derived from the Greek , (, ), meaning "woodworm", and (), meaning "resembling". It refers to their twining habit. Uses and ecology Human uses of ''Ipomoea'' include: *Most species have spectacular, colorful ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jalap
Jalap is a cathartic drug, largely obsolete in Western medicine, consisting of the tuberous roots of ''Ipomoea purga'', a convolvulaceous plant growing on the eastern declivities of the Sierra Madre Oriental of Mexico at an elevation of above sea level, more especially about the neighbourhood of Chiconquiaco on the eastern slope of the Cofre de Perote in the state of Veracruz. Jalap has been known in Europe since the beginning of the 17th century, and derives its name from the city of Xalapa in Mexico, near which it grows, but its botanical source was not accurately determined until 1829, when Dr. J. R. Coxe of Philadelphia published a description. The ordinary drug is distinguished in commerce as Vera Cruz jalap, from the name of the port whence it is shipped. Jalap has been cultivated for many years in India, chiefly at Ootacamund, and grows there as easily as a yam, often producing clusters of tubers weighing over 9 lb; but these, as they differ in appearance from the commer ...

John The Conqueror
John the Conqueror, also known as High John de Conqueror, John, Jack, and many other folk variants, is a folk hero from African-American folklore. He is associated with the roots of ''Ipomoea purga'', the John the Conqueror root or John the Conqueroo, to which magical powers are ascribed in American folklore, especially among the hoodoo tradition of folk magic. Muddy Waters mentions him as Johnny Cocheroo in the songs "Mannish Boy" and "I'm Your Hoochie Coochie Man". In "Mannish Boy", the line is "I think I'll go down/To old Kansas too/I'm gonna bring back my second cousin/That little Johnny Conqueroo" and in "I'm Your Hoochie Coochie Man", it is called "John De Conquer Blue". Folk hero Sometimes, John is an African prince (son of a king of Congo), said to have ridden a giant crow called "Old Familiar." He was sold as a slave in the Americas. Despite his enslavement, his spirit was never broken. He survived in folklore as a reluctant folk hero, a sort of trickster figure, be ...

Naturalisation (biology)
Naturalisation (or naturalization) is the ecological phenomenon through which a species, taxon, or population of exotic (as opposed to native) origin integrates into a given ecosystem, becoming capable of reproducing and growing in it, and proceeds to disseminate spontaneously. In some instances, the presence of a species in a given ecosystem is so ancient that it cannot be presupposed whether it is native or introduced. Generally, any introduced species may (in the wild) either go extinct or naturalise in its new environment. Some populations do not sustain themselves reproductively, but exist because of continued influx from elsewhere. Such a non-sustaining population, or the individuals within it, are said to be adventive. Cultivated plants are a major source of adventive populations. The above refers to ''naturalize'' as an intransitive verb, as in, "The species naturalized". In North America it is common to use ''naturalize'' as a transitive verb, as in, "City staff nat ...

Cathartic
In medicine, a cathartic is a substance that ''accelerates'' defecation. This is similar to a laxative, which is a substance that ''eases'' defecation, usually by softening feces. It is possible for a substance to be both a laxative and a cathartic. However, agents such as psyllium seed husks increase the bulk of the feces. Cathartics such as sorbitol, magnesium citrate, magnesium sulfate, or sodium sulfate were previously used as a form of gastrointestinal decontamination following poisoning via ingestion. They are no longer routinely recommended for poisonings. High-dose cathartics may be an effective means of ridding the lower gastrointestinal tract of toxins; however, they carry a risk of electrolyte imbalances and dehydration. Catharsis can be an effect of pesticide poisonings, such as with elemental sulfur Sulfur (or sulphur in British English) is a chemical element with the symbol S and atomic number 16. It is abundant, multivalent and nonmetallic. Under normal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diarrhea
Diarrhea, also spelled diarrhoea, is the condition of having at least three loose, liquid, or watery bowel movements each day. It often lasts for a few days and can result in dehydration due to fluid loss. Signs of dehydration often begin with loss of the normal stretchiness of the skin and irritable behaviour. This can progress to decreased urination, loss of skin color, a fast heart rate, and a decrease in responsiveness as it becomes more severe. Loose but non-watery stools in babies who are exclusively breastfed, however, are normal. The most common cause is an infection of the intestines due to either a virus, bacterium, or parasite—a condition also known as gastroenteritis. These infections are often acquired from food or water that has been contaminated by feces, or directly from another person who is infected. The three types of diarrhea are: short duration watery diarrhea, short duration bloody diarrhea, and persistent diarrhea (lasting more than two weeks, w ...

Ethanol
Ethanol (abbr. EtOH; also called ethyl alcohol, grain alcohol, drinking alcohol, or simply alcohol) is an organic compound. It is an Alcohol (chemistry), alcohol with the chemical formula . Its formula can be also written as or (an ethyl group linked to a hydroxyl group). Ethanol is a Volatility (chemistry), volatile, Combustibility and flammability, flammable, colorless liquid with a characteristic wine-like odor and pungent taste. It is a psychoactive recreational drug, the active ingredient in alcoholic drinks. Ethanol is naturally produced by the fermentation process of Carbohydrate, sugars by yeasts or via Petrochemistry, petrochemical processes such as ethylene hydration. It has medical applications as an antiseptic and disinfectant. It is used as a chemical solvent and in the Chemical synthesis, synthesis of organic compounds, and as a Alcohol fuel, fuel source. Ethanol also can be dehydrated to make ethylene, an important chemical feedstock. As of 2006, world produ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diethyl Ether
Diethyl ether, or simply ether, is an organic compound in the ether class with the formula , sometimes abbreviated as (see Pseudoelement symbols). It is a colourless, highly volatile, sweet-smelling ("ethereal odour"), extremely flammable liquid. It is commonly used as a solvent in laboratories and as a starting fluid for some engines. It was formerly used as a general anesthetic, until non-flammable drugs were developed, such as halothane. It has been used as a recreational drug to cause intoxication. Production Most diethyl ether is produced as a byproduct of the vapor-phase hydration of ethylene to make ethanol. This process uses solid-supported phosphoric acid catalysts and can be adjusted to make more ether if the need arises. Vapor-phase dehydration of ethanol over some alumina catalysts can give diethyl ether yields of up to 95%. Diethyl ether can be prepared both in laboratories and on an industrial scale by the acid ether synthesis. Ethanol is mixed with a stro ...
