Lay out your problem and what you are trying to fix... its best to get to the root of the problem and not mask them with drugs and suppliments...
What are these herbal supplements used for? Since herbal supplements in general are not regulated by the FDA, I would be careful as they may or may not be 100% of what they say on the label. Because supplements are "natural" or herbal, they still are not without side effects or ingredients which you might be sensitive to or which might cause adverse reactions within your body.
