A tincture is an alcoholic solution of a non-volatile substance (for example, tincture of iodine).
“Very uniform and reliable tinctures may be made of most indigenous plants, by procuring the part to be employed, at the proper season, while it is green and fresh, bruising it well, and covering it with good strong whiskey, or with alcohol diluted with one part of water to three of alcohol, corking tightly, and letting it stand about fourteen days, when the tincture may be filtered or poured off from the drugs, and will be ready for use. Prepared in this imperfect manner, they will be found to be much more reliable than any of the fluid extracts found in the drug-stores. An excess of the crude drug should be used in preparing the tincture to insure a perfect saturation of the alcohol with its active principles.”
