Sambucus Canadensis, American Elder. The recent flowers in warm infusion are diaphoretic and stimulant; the cold infusion, diuretic. The ec. tr. is made from the green inner bark. The eclectics esteem it in edametous skin diseases and in depraved deposits and watery infiltration. Ten drop doses are employed as an alterative. Very large doses are hydragogue cathartic and emetic. The ec. tr., in I5 to 30 I. doses, is safe and effective in dropsy, most markedly so in post-scarlatinal dropsy. The f.e. (flowers) is given in doses of 0 to 2 f3.
