Query: A must have for your medical library!

I saw Brenda on a PBS show about gut solutions which I found to be very helpful in diagnosing my peri menopausal symptoms (which I then related to my Dr. who agreed with her suggestions/explanations). I immediately requested the book at my local library and found it so helpful that I purchased a used copy in good condition through Amazon.com.This book really is a must have for your home medical library. It's a great resource. I've been taking the probiotics purchased from Brendas company for seven months now and I am absolutely amazed that I have not had any other gastrointestinal issues since the first week I started taking them. I suffered for months before seeing this show and purchasing this book. I'm not usually one to rate "medical" items but I feel as though I've come across a miracle with this one!
