mention the factor responsible for fall in popularity of tincture
Answers
Explanation:
tincture is typically an extract of plant or animal material dissolved in ethanol (ethyl alcohol). Solvent concentrations of 25–60% are common, but may run as high as 90%.[1] In chemistry, a tincture is a solution that has ethanol as its solvent. In herbal medicine, alcoholic tinctures are made with various ethanol concentrations, 20% being the most common.[1]
Other solvents for producing tinctures include vinegar, glycerol (also called glycerine), diethyl ether and propylene glycol, not all of which can be used for internal consumption. Ethanol has the advantage of being an excellent solvent for both acidic and basic (alkaline) constituents. A tincture using glycerine is called a glycerite. Glycerine is generally a poorer solvent than ethanol. Vinegar, being acidic, is a better solvent for obtaining alkaloids but a poorer solvent for acidic components. For individuals who choose not to ingest alcohol, non-alcoholic extracts offer an alternative for preparations meant to be taken internally.
Low volatility substances such as iodine and mercurochrome can also be turned into tinctures.
Factor responsible for fall in popularity of tincture:
- Tincture is the medicine prepared by dissolving drug in alcohol.
- Tincture of iodine is very common, iodine tincture, or weak iodine solution is applied as antiseptic.
- The plant or animal extract is made to dissolve in the solution which is tincture. Hence the solution is called tincture.
- It contains 2–7% of elemental iodine, along with the "potassium iodide or sodium iodide", that has dissolved in the "mixture of ethanol and water".
- Tincture solutions are also characterized by the alcohol presence.
