Thank you so much for taking the time to respond with more info and the links. I have never looked up the tongue map so that was pretty interesting. I have been using the Braggs ACV almost daily for several years after reading the Braggs ACV book. As I was reading your post, I was also sipping on some hot lemon ginger tea with honey that I made from fresh ingredients. Time to get off the computer and read my coconut oil book while I use the castor oil pack.
