There are many options. Let the MD's handle that type of situation. Dr.'s don't often ask about herbs. I think an important point was brought up by the question of medications. Always tell all the doctors you are seeing about the things your other doctors are giving you.
Herbs are medicine.
This is complicated stuff. Herbs are usually safer than bio meds. There are over one million hospitalizations per year in the USA as a response to biomedical products. There can be potentiating effects between herbs and meds, or attenuating effects. But the action on the body is very different between biomed and herbs.
