Healing Properties and Warning

The jalap root contains several carbohydrates and two glycosides: jalapine and convolvuline, which are its active components. It has an intense purgative action, which is well tolerated and does not cause colic in low doses. Jalap is recommended when drastic action has to be exerted on the intestine. Not having a bad taste, it also has vermifuge and emmenagogue (stimulates menstruation) properties.

WARNING! Never take this plant for colitis (inflammation of the intestine), nor during pregnancy.
