Modern Research

Studies confirm Ipomoea purga’s powerful laxative and anthelmintic effects, but its use is restricted due to its potency and potential side effects.

Jalap remains a historically significant herb, primarily used for its strong purgative and detoxifying effects, but requires professional guidance due to its potency.
