SYNONYM: Extract of cotton-root bark.

Preparation.—Exhaust the recent inner bark of the root of the cotton plant, in small pieces, with water, a sufficient quantity, proceeding in the same manner as explained for the preparation of Aqueous Extracts, on page 758. The pilular extract should be placed in small jars, and kept well covered, to prevent, as much as possible, any loss of its virtues. Unless made of the recent root it will be inert, and even then it is a question as to whether the heat of concentration does not materially affect the product.

Medical Uses and Dosage.—Extract of cotton-root bark is emmenagogue and abortifacient. It will be found useful in amenorrhoea and dysmenorrhoea, combined with belladonna and quinine. The dose is from 1 to 5 or 10 grains, 3 times a day (J. King).
