Vervain

verbena officinalis l.

Safety & Contraindications

Class 2b, without stating the reason, perhaps rosmarinic acid refers to gonadotropic and lactagogue activity. CAN notes no toxicity or side effects for vervain itself, but adds that high doses of verbenalin can cause CNS paralysis, convulsions, and stupor. Excessive doses may interfere with blood pressure and hormone therapy. Reportedly abortifacient and oxytocic, it should not be taken in pregnancy. Excessive use should be avoided.
