Query: Sorry to say it did not work for us

This book promises many cures for many symptom, however in my and my son's case it just did not work. The first problem was sore throat which continued. Second problem we tried to cure was acne. My son tried using oregano oil under his tongue and as topical to the acne. All that did was make his acne really red and he actually broke out even more. He continued with it for two weeks and we gave up and brought acne-free product. I had only one pimple which was large, I also applied oregano oil on it. It became larger and really red. It has been over 2 months and that old pimple site still has a red mark on it. I have been really disappointed with his book and his product sorry to say I was really looking for a cure.
