Preparation.—"Take of buchu leaves, in No. 20 powder, 2 ½ ounces (av.); proof-spirit, 1 pint (Imp.)"—(Br. Pharm., 1885). Prepare as directed under Tinctura Sennae. This produces a green-brown tincture, possessing the sensible properties of buchu. The reparation of the British Pharmacopoeia (1898) is similar, except that 4 ounces of the leaves are directed, and alcohol (60 per cent), a sufficient quantity to make 1 pint of tincture. (Modern shorthand: 1:4 60 %)
Action, Medical Uses, and Dosage.—(See Buchu.) This preparation is less eligible than the infusion. Dose, 1 to 3 fluid drachms, well diluted with water.
