[33 fl℥, 391♏]. Mix alcohol and water in the proportion of seven hundred and fifty cubic centimeters (750 Cc.) [25 fl℥, 173♏] of alcohol to two hundred and fifty cubic centimeters (250 Cc.) [8 fl℥, 218♏] of water. Moisten the powder with one hundred cubic centimeters (100 Cc.) [3 fl℥, 183♏] of the menstruum, and macerate for 24 hours; then pack it firmly in a cylindrical percolator, and gradually pour menstruum upon it, until one thousand cubic centimeters (1000 Cc.) [33 fl℥, 391♏] of tincture are obtained"—(U. S. P.). Tincture of valerian depends, for its color, upon the condition of the valerian employed. Its color is either brown or red-brown, and, when added to water, it renders the latter turbid. The odor and taste of valerian is well preserved.
