a medicinal alcoholic preparation derived from raw vegetable matter. Tinctures are usually prepared by infusing the vegetable matter in ethyl alcohol or, less commonly, in a mixture of ethyl alcohol and medicinal ether. Another less common method involves dissolving an extract from the plant. Tinctures are classified as galenicals and are prescribed for internal use only.
