Action And Therapeutics Of Pomegranate

Pomegranate is a powerful astringent, and the decoction B. P., 1 to 5; dose, 1/2 to 2 fl. oz.; 15. to 60. c.c may be used as a gargle for a sore throat. In large doses it is emetic and purgative. It is an anthelmintic for the tapeworm. It is so disagreeable that it is rarely used, but if employed the decoction may be given every hour for four hours before breakfast. A purge should be administered the night before and a few hours after breakfast. Pelletierine dose of tannate, (not official), 3 to 6 gr.; .20 to .40 gm. is the active anthelmintic principle, and is said to be very efficient for killing the common tapeworm. Large doses of pelletierine given to animals act like curare.
