I have hormonal acne (cystic/whitehe on chin) at ovulation and before period. is vitex harmful to take? will it help acne? any other recommendations?

Unpredictable effect: As with many herbals, the actions and risks are incompletely understood and good studies are lacking. Vitex could potentially interact with a number of medications including the birth control pill and should not be taken when pregnant or breast feeding. While it might possibly help acne, you might want to consult a dermatologist. If its an option, birth control pills will often help acne.
