You are in Member Communities . I cannot find much information anywhere about this, and I'm anxious that relatives and friends of mine who self-treat with herbs are going to get into trouble. Their pharmacists can't answer their questions. I also am concerned about people combining herbs with pharmaceutical medications. The common perception that herbs are completely safe worries me too.
Most herbs are very safe if used appropriately in recommended doses.
However, some herbs have very powerful effects in even small amounts, some are contraindicated in people with certain health conditions, and some should not be combined with prescription medications. There is limited information on combining specific herbs with other medications. Since herbs have just begun to have widespread use in this country and we have not yet had lots of experience with combining them with pharmaceutical drugs, I would expect there are interactions that we are not yet aware of. My general advice is to combine herbs with pharmaceutical medications only under a doctor's supervision. At the present time I have several specific cautions.
