"Veratrum Viride in No. 60 powder, one hundred grammes [or 3 ounces av., 231 grains], to make one thousand mils [or 33 fluidounces, 6 ½ fluidrachms]. Prepare a Tincture by Type Process P, using alcohol 'as the menstruum." U. S.

The U. S. tincture of American hellebore of 1890 was of the same strength as Norwood's tincture, which was prepared by its author from fresh drug (240 grains for each fluidounce of alcohol), and was supposed to be saturated. The U. S. P. 1890 tincture was made from dried and powdered veratrum (40 Gm. in 100 mils strength) but was reduced by the U. S. P. VIII from 40 per cent. to 10 per cent. in order that it might conform with the recommendations of the Brussels Congress concerning potent tinctures (see Tinctures). This action has resulted in increasing the use of the fluid-extract, which is a better preparation. The U. S. P. IX has returned to the exclusive use of veratrum viride. Veratrum album was also recognized in the U. S. P. VIII.

Dose, of U. S. tincture, ten to thirty minims (0.6-1.8 mils).
