The dried bark of Fraxinus sambucifolia, Lamarck, and Fraxinus americana, Linné (Nat. Ord. Oleaceae.) Forest trees of northern United States and Canada. Dose, 10 to 60 grains.
Common Names: 1. Black Ash, Elder-leaved Ash. 2. White Ash.

Principal Constituent.—A bitter alkaloid in minute quantity.
Preparation.—Specific Medicine Fraxinus. Dose, 10 to 60 drops.

Action and Therapy.—Probably of some value in uterine subinvolution, with pelvic heaviness and dragging pain, and soreness and headache at the vertex and occipital base of the skull. That it will cure uterine tumors, as has been claimed, is extremely doubtful and lacks sufficient proof to be given credence. Its relative, the White Ash, is said to be cathartic.
