197. Hydrangea, N.F.

Botanical name: 

197. HYDRANGEA, N.F.—The root of Hydran'gea arbores'cens Linné. (See Conspectus.) Habitat: United States. It consists of several bent, branched roots, arising from a thick, knotty head, or, as usually seen, of pieces of these roots cut up into various lengths. The rather thick, light gray, or pale brown bark is longitudinally ridged and covered with rust-colored patches, and separates easily from the tough, white, tasteless wood; wood-wedges long, narrow; odorless; taste of bark sweetish, afterward pungent. Used as a diuretic and as an antilithic in those cases where there is an alkalinity of the urine and a tendency toward the deposition of phosphatic calculi. Dose: 30 to 60 gr. (2 to 4 Gm.).
