Tinctures alcoholic solutions

Tincture- alcoholic solution of active constituents of vegetable drugs. 

Medical Usage. Isopropyl alcohol is also used as an antiseptic and disinfectant for home, hospital, and industry (see Disinfectants and antiseptics). It is about twice as effective as ethyl alcohol in these appHcations (153,154). Rubbing alcohol, a popular 70 vol % isopropyl alcohol-in-water mixture, exemplifies the medicinal use of isopropyl alcohol. Other examples include 30 vol % isopropyl alcohol solutions for medicinal liniments, tinctures of green soap, scalp tonics, and tincture of mercurophen. It is contained in pharmaceuticals, eg, local anesthetics, tincture of iodine, and bathing solutions for surgical sutures and dressings. Over 200 uses of isopropyl alcohol have been tabulated (2). 

Tinctures are alcoholic solutions that are prepared by treating natural raw materials with ethanol or ethanol-water mixtures. They can also be obtained by dissolving other extracts in these solvents. Tinctures are sometimes called infusions. 

By Alcoholic Solution.—The extraction of odors by means of alcohol from scented fats, will be more fully explained under the head of Extraits. The Editor will here limit himself to the description of essences and tinctures. 

You are probably familiar with the 2% alcoholic solution of iodine known as tincture of iodine. It is found in almost every home medicine cabinet and is used as a disinfectant for wounds. Iodine has many other uses — in photography and in the preparation of various medicines and dyes. 

Iodine is necessary for the proper function of the thyroid gland in humans. Dietary deficiencies can be avoided by the occasional consumption of seafood or by using iodized salt, which combines common table salt (NaCl) with potassium iodide (KI). Iodine is a useful antiseptic, either as tincture of iodine (an alcohol solution of I2), or as an aqueous solution of provi-done iodine (Betadine). see also Halogens Inorganic Chemistry.

Iodine is not used as widely as the other halogens. A 50 percent (by mass) alcohol solution of iodine, known as tincture of iodine, is used medicinally as an antiseptic. Iodine is an essential constituent of the thyroid hormone thyroxine ... 

Tincture Alcohol/hydroalcohol solutions derived from botanicals where the concentration of the herbal product generally remains very low. 

A food extract, such as a lemon extract, is really not a chemical extraction but consists of the essential oils that are mechanically pressed out of lemon skin and then kept in a 45% solution of alcohol. A drug extract is called a tincture. Tinctures are usually alcohol solutions and are liquid-solid extractions. Examples are the tincture of iodine, oil of wintergreen, oil of clove, and oil of peppermint. Cosmetic extracts such as ambergris, musk, castor, and benzoin, are called essences and are used to make perfumes. 

Tincture A solution of medical substance in alcohol. Also a dye product. Tincture of galls Tannin extracted from galls. 

Valepotriates are unstable compounds they are thermolabile and decompose under acidic or alkaline conditions, as well as in alcoholic solutions. After hydrolysis valeric and isovaleric acids are found among other compounds. The main decomposition products of the valepotriates are the yellow-coloured baldrinals (baldrinal (47), homobaldrinal (48)). The baldrinals are chemically reactive and may subsequently form polymers. Although valepotriates were once thought to be the active ingredients, these compounds are chemically unstable and are not found in teas and tinctures. Instead their degraded products, baldrinals, are... 

Medicinal tinctures are solutions involving an animal, vegetable, or chemical substance or extract dissolved in alcohol or alcohol and water. For example, tincture of iodine is a preparation of iodine and sodium iodide in diluted ethanol used as a topical anti-infective. 

For use in perfume oils either an alcoholic solution (C. tincture) is prepared or crude C. is extracted with a suitable solvent such as ethanol or acetone. The product (C. absolute) is a viscous, gray to gray-brown mass with a strong animal, musk-like, slightly fecal odor. 

TINCTURES. Alcoholic or hydroalcoholic solutions usually containing the active principles of botanicals in comparatively low concentrations. They are generally prepared either by maceration or percolation or by dilution of their corresponding fluid extracts or native extracts. The strengths of tinctures are generally 1 0.1 or 1 0.2 TNF-a.

Iodine as such finds few uses but a solution in alcohol and water, also containing potassium iodide ( tincture of iodine was commonly used as an antiseptic for cuts and wounds, but had rather an irritant action. Iodoform (triiodomethane), CHI3, is also an antiseptic, but newer compounds of iodine are now in use. Silver iodide, like silver bromide, is extensively used in the photographic industry. 

Disinfection destroys pathogenic organisms. This procedure can render an object safe for use. Disinfectants include solutions of hypochlorites, tinctures of iodine or iodophores, phenoHc derivatives, quaternary ammonium salts, ethyl alcohol, formaldehyde, glutaraldehyde, and hydrogen peroxide (see Disinfectants AND antiseptics). Effective use of disinfected materials must be judged by properly trained personnel. 

Iodine. Iodine has been important for many years, primarily as an antiseptic (see Iodine and iodine compounds). In the American Civil War physicians used it to treat battie wounds. Elemental iodine is not very soluble in water, but dissolves readily when sodium iodide is added, forming triiodide + I I Iodine may thus be used as an aqueous solution but it has generally been used as a tincture of 2% iodine in 70% alcohol. Tests on... 

Of the four halogens, iodine is the weakest oxidizing agent. Tincture of iodine, a 10% solution of I2 in alcohol, is sometimes used as an antiseptic. Hospitals most often use a product called povidone-iodine, a quite powerful iodine-containing antiseptic and disinfectant, which can be diluted with water to the desired strength. These applications of molecular iodine should not delude you into thinking that the solid is harmless. On the contrary, if I2(s) is allowed to remain in contact with your skin, it can cause painful bums that are slow to heal. 

Iodine is the least reactive of the elements in the halogen group 17. Most people associate iodine with the dark-brown color of the tincture of iodine used as an antiseptic for minor skin abrasions and cuts. A tincture is a 50% solution of iodine in alcohol. Although it is still used, iodine is no longer the antibiotic of choice for small skin wounds. Since iodine is a poison that kills bacteria, iodine tablets are often used by campers and others to purify water that is taken from outdoor streams. 

Tincture. An alcoholic or hydroalcoholic solution prepared from biological substances or from chemical substances.
