Was it Concor COR 2.5 mg? If so, please read on. Yes, you can use Vinpoven, Concor, berberine and black cumin oil as long as the oil and all other medications/preparations are taken at an interval of each other. About 1-2 hours of interval between individual preparations and the oil will be fully sufficient and will protect against interactions. Please remember to wash down your medications with water, besides, there is no reason to worry.
