does barberry interact with clopidogrel or metoprolol....I also have bile reflux and limited on medications because of clopidogrel and ended up in ER a month ago because of esophagus. My digestive tract bothers me in several ways and do not have a good diet due to multiple food allergies, foods I can't have due to health issues; I have 2 stents in my heart and high triglycerides and have begun using a sugar blocker several weeks ago...at doctors approval of course.
