Common Names: Yarrow, Milfoil, Thousand Leaf.
Principal Constituents.—The bitter alkaloid achilleine (C20H38N2O15), achilleic acid (aconitic acid); a volatile oil, tannin, and potassium and calcium salts.
Preparation.—Specific Medicine Achillea. Dose, 5 to 30 drops.
Specific Indications.—Atony and relaxation of tissue, with free discharges; passive hemorrhage.
