JA′LAP. Syn. Jalapæ radix, Jalapa, B. P. (Ph. L. & D.) Convolvuli jalapæ radix (Ph. E.), L. The dried tubercles of the Exogonium purga, I. jalapa—(Royle.) Jalap is a powerful stimulant and drastic purgative, producing copious liquid stools; but when judiciously administered, both safe and efficacious. It appears to be intermediate in its action between aloes and scammony.—Dose, 10 to 30 gr., in powder; in constipation, cerebral affections, dropsies, obstructed menstruation,
worms, &c. Owing to its irritant properties, its use is contra-indicated in inflammatory affections of the alimentary canal, and after surgical operations connected with the abdomen and pelvis. It is usually administered in combination with sulphate of potassa or bitartrate of potassa and ginger; with mercurials, as the case may indicate. The powder is very generally adulterated.
