Tinctura Colchici Composita.—Compound Tincture of Colchicum.
Preparation.—Take of colchicum seed, in fine powder, 2 ounces; black cohosh root, in fine powder, 3 ounces; diluted alcohol, 2 pints, or a sufficient quantity. Form it into a tincture by maceration or percolation, and make 2 pints of tincture. Or, it may be made by adding together equal parts of the tinctures of colchicum seed and black cohosh root.
Action, Medical Uses, and Dosage.—This forms an excellent agent in inflammatory rheumatism and gout, and has proved a superior remedy in phlegmasia dolens, or the swelled leg of parturient women. The dose is from 10 to 60 drops, or more, as circumstances indicate, every 1, 2, 3, or 4 hours. Iodide of potassium, 15 grains to 1 ounce of the tincture, may frequently be added with advantage (J. King).
