Hi LaPopessa,
Please have a look at www (dot) drugdigest (dot) org. (I could probably post a link, as it doesn't appear to sell anything, but since it is sponsored by Express Scripts it might be against posting guidelines. As a moderator I'd then have to remove it and quote the posting guidelines to myself

)
This is a really great reference site IMO, not only for looking up direct information on drugs and herbals, but it also has a terrific drug and herbal interaction 'checker'. You can select the medications you're already taking, and plug in any you're considering, to see what the known risks are with the combination.
My own personal feeling is against the use of herbal supplements. Admittedly I am conservative when it comes to experimentation with my health. But I just do not have confidence in the safety of these supplements because the FDA does not regulate them. Not that I believe the FDA to be foolproof! But since herbal supplements are not considered 'drugs', there is no standardization for strength, dosage, or even requiring the same chemical compound. One bottle may simply be ineffective while another bottle may give side effects, perhaps serious ones.
If, after checking the site above for information and using the 'interaction checker', you do wish to try a supplement, please check with your doctor first. No internet site, including this one, can ever be a substitute for your own care provider, who knows you and your medical history.
Blessings,
