I believe all the answers here are correct, but in regards to fitmom's comment, I would like to add this. In Minnesota, a doctor now can have their licence suspended for talking about natural remedies as opposed to either prescription or over the counter medications. Sounds stupid, but true. The bill was passed about a year and a half ago.
Drug companies have one of the biggest lobbiest groups in the nation. Is that not a shame. And with the side affects of most drugs, it has to make you wonder what is more important. The patient, or the drug companies wallet.
Of course, if you do decide on natural treatment, do check to make sure there are no contra-indications for possible side affects they may have with any prescription drugs you may be taking.
