Tinctura Cinchona. Edin. Tinctura Lancifoli;e Cik-CHONiE. Dub. Tincture of Lance-leaved Cinchona.

" Take of cinchona bark in powder, four ounces; proofspirit, two ■pounds and a half, (two pints, Dub.) Digest forseven days, and filter through paper."

Although this tincture contains the active principles of cin-chona bark in considerable quantity, yet, from the nature ofthe vehicle, it cannot be given in sufficiently large doses toproduce the beneficial effects of the bark in substance; it istherefore used chiefly as an adjunct to the infusion or decoc-tion. The dose is from f5j. to f5iv.

Tinctu'ra Cincho'n^ Ammoniata. Lond. AmmoniatedTincture of Bark.

" Take of lance-leaved cinchona bark powdered, fourounces ,• aromatic spirit of ammonia, two pints. Macerate forten days, and filter."

This is the formula of 1787, which was rejected withoutany proper reason in 1809. It is extremely useful in dyspepticcomplaints attended with much acidity.

TINCTU'RA CINCHO'NiE COMPOS'ITA. 1 Lond.Edin. Dub. Compound Tincture of Cinchona.

" Take of lance-leaved cinchona bark powdered, two ounces ;dried orange-peel, one ounce and a half; (half an ounce, Dub.)Virginian snake-root bruised, three drachms; saffron, a drachm;cochineal in powder, two scruples; proof spirit, twenty fluidounces. Macerate for fourteen (seven Edin.) days, and filter."

This tincture is more grateful than the former; and althoughit contains less cinchona, yet the addition of the other ingre-dients renders it more useful both as a stomachic and a febrifuge.It is the same as the celebrated tincture of Huxham 3 , whogenerally gave it in intermittents and low nervous fevers, indiluted wine or any proper vehicle, with ten or fifteen drops ofelixir of vitriol, (aromatic sulphuric acid, Edin.) The dose isfrom t'5j. to f5iij. or more in intermittents.
