Acidum Trichloraceticum (Acid. Trichloracet.), Trichloracetic Acid, U.S.P.—CCl3.COOH.
Colorless, deliquescent crystals with a slight characteristic odor. Miscible with water and with alcohol.
Action and Uses: Caustic, for the removal of warts and other skin blemishes. Used also as local hemostatic.
Aconitina (Aconitin.), Aconitine, U.S.P.—An alkaloid obtained from aconite.
A white, odorless powder. Very slightly soluble in water, soluble in alcohol (1:28) and in ether (1:65).
Action and Uses: Similar to those described under aconite. As several alkaloidal preparations of aconite, of varying activity, are sold under the name of aconitine, its use is not advisable.
Dosage: 0.15 mg. or 1/400 grain (U.S.P.).
Oleatum Aconitinae (Oleat. Aconitin.), Oleate of Aconitine, N.F.—Aconitine (2%) in oleic acid and olive oil.

*Aconitum (Aconit.), Aconite, U.S.P. (Monkshood, Aconite Root, Aconiti Tuber, P.I.).—A tuberous root, yielding about 0.5 per cent. of ether-soluble alkaloids; also assayed biologically. Physicians should specify preparations that have been assayed biologically, since the alkaloidal assay is not a reliable index of activity.
