2. (Ammoniated; Unguentum aconiti ammoniatum—Turnbull.) Ammoniated extract of aconite, 1 part; lard, 3 parts. In neuralgia, paralysis, old rheumatic affections, &c. The use of the above preparations of aconite requires the greatest caution. They
are intended as substitutes for OINTMENT OF ACONITINE, a still more dangerous preparation.
Ointment of Acon′itine. Syn. Unguentum aconitinæ, L. Prep. 1. (Dr Garrod.) Pure aconitine, 1 gr.; lard, 1 dr.; mix by careful trituration.
2. (Dr Turnbull.) Aconitine, 2 gr.; rectified spirit, 6 or 7 drops; triturate together, then add of lard, 1 dr., and mix well.
3. (B. P.) Aconitia (aconitine), 8 gr.; rectified spirit, 1⁄2 dr.; dissolve and add lard, 1 oz.; mix.
Use, &c. As a topical benumber in neuralgic affections, rheumatic pains, &c. Its application generally occasions considerable tingling, and sometimes redness of the part to which it is applied, followed by temporary loss of sensation in the skin and the cessation of the pain. For slight cases Dr Paris formerly employed only 1 gr. to the oz. Owing to the intensely poisonous nature of aconitine, this ointment must be both prepared and used with great caution, and must never be applied to an abraded surface. It is seldom employed, owing to its extreme costliness. See Aconitia, and above.
