Cleavers

galium aparine

Safety & Contraindications

Class 1. “Hazards and/or side effects not recorded for proper therapeutic dosages”. None known. Diabetics should use the expressed juice only with caution. Excessive use of cleavers should be avoided, especially during pregnancy. Lower arterial blood pressure in canines with no slowing of heart and no toxic effects. Like other iridoids, asperuloside is a mild laxative. It can be converted to prostanoid intermediates. I was surprised to find harmine, 1-hydroxydesoxypeganin, 8-hydroxy-2,3-dehydrodesoxypeganin, and protopine listed for this plant by the Herbal PDR. I am reluctant to enter them in my database without checking their original sources.
