Does Black Cohosh Interact with Medications?

Is there any interaction between black cohosh and thyroid or cholesterol medicines? I am having hot flashes that increasing in number and intensity. I would like to try something herbal before going to an estrogen medication.

There are no known interactions between drugs and black cohosh. For more information on herbs for hot flashes, please see our website www.richters.com. Choose "Q&A" from the main menu, then enter "hot flash" for the search. For information on menopause, enter "menopaus" for the search.
