Everything I have read, and experienced, has put herbs and other natural remedies on my no-no list.
They did work when I wasn't on medication. I took St. Johns Wort and Ginkgo Biloba, and it really did help, for a while. At times I think it was just in my mind (I do so hate that phrase "just in my mind") but... once I got on medication (zoloft, etc.) it was horrible! They cancelled each other out.
Now that I am back on my meds, on a regular basis, I've learned that just about everything cancels my meds out. Even vitamins! I've yet to find a good calcium supplement that doesn't reak havoc on me.
I truly think alternative medicine has its place, but... I pester my med doctor constantly about what I can and can not take with my medications. Luckily she loves me :)
I don't think I will ever understand why people don't ask their doctors first before trying something new. They may not agree with what you're considering, but they will tell you the pro's and con's of it. Most importantly they'll tell you the dangers. You're paying the doctors, make them work for you!
Sorry David, had to rant there. Got my soapbox out already! ;)
