"Valerian, in No. 40 powder, two hundred grammes [or 7 ounces av., 24 grains], to make one thousand mils [or 33 fluidounces, 6 ½ fluidrachms]. Prepare a Tincture by Type Process P, using a mixture of three volumes of alcohol and one volume of water as the menstruum." U. S.

The proportion of alcohol was increased in the U. S. 1890 tincture, to prevent precipitation, and this strength has been retained in the present revision. It is now three parts of alcohol to one part of water. The tincture possesses the properties of valerian, but cannot be given in some cases, so as to produce the full effects of the root, without stimulating too highly, in consequence of the large proportion of spirit. It deposits on standing a black, very cohesive precipitate, with starch, and a yellow extractive matter. (Meniere.)

Dose, one to four fluidrachms (3.75-15.0 mils).
