Chlorodyne
Chlorodyne was one of the best known patent medicines sold in the British Isles. It was invented in the 19th century by a Dr. John Collis Browne, a doctor in the British Indian Army; its original purpose was in the treatment of cholera. Browne sold his formula to the pharmacist John Thistlewood Davenport, who advertised it widely, as a treatment for cholera, diarrhea, insomnia, neuralgia, migraines, etc. As its principal ingredients were a mixture of laudanum (an alcoholic solution of opium), tincture of cannabis, and chloroform, it readily lived up to its claims of relieving pain, as a sedative, and for the treatment of diarrhea. Imitations Chlorodyne sold extremely well for many years; as its active ingredients were well known, local chemists' shops would also make up cheaper generic versions for sale to their customers. Here is an example of such a generic formulation, from ''Materia Medica'' by William Hale-White & A.H. Douthwaite, 21st edition (1932): "Tinctura Chlorofor ...

Sorbitol
Sorbitol (), less commonly known as glucitol (), is a sugar alcohol with a sweet taste which the human body metabolizes slowly. It can be obtained by reduction of glucose, which changes the converted aldehyde group (−CHO) to a primary alcohol group (−CH2OH). Most sorbitol is made from potato starch, but it is also found in nature, for example in apples, pears, peaches, and prunes. It is converted to fructose by sorbitol-6-phosphate 2-dehydrogenase. Sorbitol is an isomer of mannitol, another sugar alcohol; the two differ only in the orientation of the hydroxyl group on carbon 2.Kearsley, M. W.; Deis, R. C. Sorbitol and Mannitol. In Sweeteners and Sugar Alternatives in Food Technology; Ames: Oxford, 2006; pp 249-249-261. While similar, the two sugar alcohols have very different sources in nature, melting points, and uses. As an over-the-counter drug, sorbitol is used as a laxative to treat constipation. Synthesis Sorbitol may be synthesised via a glucose reduction react ...

Hypromellose
Hypromellose ( INN), short for hydroxypropyl methylcellulose (HPMC), is a semisynthetic, inert, viscoelastic polymer used in eye drops, as well as an excipient and controlled-delivery component in oral medicaments, found in a variety of commercial products. As a food additive, hypromellose is an emulsifier, thickening and suspending agent, and an alternative to animal gelatin. Its Codex Alimentarius code (E number) is E464. Chemistry Hypromellose is a solid, and is a slightly off-white to beige powder in appearance and may be formed into granules. The compound forms colloids when dissolved in water. This non-toxic ingredient is combustible and can react vigorously with oxidizing agents. Hypromellose in an aqueous solution, like methylcellulose, exhibits a thermal gelation property. That is, when the solution heats up to a critical temperature, the solution congeals into a non-flowable but semi-flexible mass. Typically, this critical (congealing) temperature is inversely re ...

Citric Acid
Citric acid is an organic compound with the chemical formula HOC(CO2H)(CH2CO2H)2. It is a colorless weak organic acid. It occurs naturally in citrus fruits. In biochemistry, it is an intermediate in the citric acid cycle, which occurs in the metabolism of all aerobic organisms. More than two million tons of citric acid are manufactured every year. It is used widely as an acidifier, as a flavoring, and a chelating agent. A citrate is a derivative of citric acid; that is, the salts, esters, and the polyatomic anion found in solution. An example of the former, a salt is trisodium citrate; an ester is triethyl citrate. When part of a salt, the formula of the citrate anion is written as or . Natural occurrence and industrial production Citric acid occurs in a variety of fruits and vegetables, most notably citrus fruits. Lemons and limes have particularly high concentrations of the acid; it can constitute as much as 8% of the dry weight of these fruits (about 47 g ...

Menthol
Menthol is an organic compound, more specifically a monoterpenoid, made synthetically or obtained from the oils of corn mint, peppermint, or other mints. It is a waxy, clear or white crystalline substance, which is solid at room temperature and melts slightly above. The main form of menthol occurring in nature is (−)-menthol, which is assigned the (1''R'',2''S'',5''R'') configuration. Menthol has local anesthetic and counterirritant qualities, and it is widely used to relieve minor throat irritation. Menthol also acts as a weak κ-opioid receptor agonist. Structure Natural menthol exists as one pure stereoisomer, nearly always the (1''R'',2''S'',5''R'') form (bottom left corner of the diagram below). The eight possible stereoisomers are: : In the natural compound, the isopropyl group is in the '' trans'' orientation to both the methyl and hydroxyl groups. Thus, it can be drawn in any of the ways shown: : The (+)- and (−)- enantiomers of menthol are the most stab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tincture Of Cannabis
Tincture of cannabis, sometimes known as green dragon, is an alcoholic cannabis concentrate. The solubility of THC in ethanol is greater than 1 g/mL. Cannabis tinctures are used in the production of specific extracts, like nabiximols. History Cannabis tincture appeared in the United States Pharmacopoeia until 1942 (Australia 1977, UK 1970s). In the 20th century cannabis lost its appeal as a medicinal product, largely due to the development of apparently suitable alternatives, such as the hypodermic needle, water-soluble analgesics and synthetic hypnotics. A major concern of the regulatory authorities at that time was the widespread recreational use of cannabis. The pharmacological target for cannabis, the endocannabinoid system, has been researched since its discovery in the 1980s. Preparation The tincture is typically made by soaking the dried flowers of the female hemp plant (marijuana) in ethanol. The tetrahydrocannabinol (THC) and other cannabinoids dissolve into th ...

Benzoic Acid
Benzoic acid is a white (or colorless) solid organic compound with the formula , whose structure consists of a benzene ring () with a carboxyl () substituent. It is the simplest aromatic carboxylic acid. The name is derived from gum benzoin, which was for a long time its only source. Benzoic acid occurs naturally in many plants and serves as an intermediate in the biosynthesis of many secondary metabolites. Salts of benzoic acid are used as food preservatives. Benzoic acid is an important precursor for the industrial synthesis of many other organic substances. The salts and esters of benzoic acid are known as benzoates . History Benzoic acid was discovered in the sixteenth century. The dry distillation of gum benzoin was first described by Nostradamus (1556), and then by Alexius Pedemontanus (1560) and Blaise de Vigenère (1596). Justus von Liebig and Friedrich Wöhler determined the composition of benzoic acid. These latter also investigated how hippuric acid i ...

Ethanol
Ethanol (abbr. EtOH; also called ethyl alcohol, grain alcohol, drinking alcohol, or simply alcohol) is an organic compound. It is an alcohol with the chemical formula . Its formula can be also written as or (an ethyl group linked to a hydroxyl group). Ethanol is a volatile, 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 sugars by yeasts or via 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 synthesis of organic compounds, and as a fuel source. Ethanol also can be dehydrated to make ethylene, an important chemical feedstock. As of 2006, world production of ethanol was , coming mostly from Brazil and the U.S. Etymology ''Ethanol'' is the systematic name defined by the ...

Bedsit
A bedsit, bedsitter, or bed-sitting room is a form of accommodation common in some parts of the United Kingdom which consists of a single room per occupant with all occupants typically sharing a bathroom. Bedsits are included in a legal category of dwellings referred to as houses in multiple occupation (HMO). Bedsits arose from the subdivision of larger dwellings into low-cost accommodation at low conversion cost. In the UK, a growing desire for personal independence after World War II led to a reduced demand for traditional boarding houses with communal dining. Bedsits are often occupied by young single people, students, those unable to purchase their own properties, or those whose occupation is of a transitory nature; the cost is typically lower than for other types of property. Someone whose employment is a long distance from their home may sometimes rent a bedsit to reduce the cost and inconvenience of daily travel.
