I have just ordered the book "Oil of Oregano" by Dr. Cass Ingram, and I was able to look at several pages. One of the things that called my attention on the book is that there are imitations of oregano oil such as thyme oil and marjoram oil. These oil imitations are also label as oegano oil and they are toxic. So the question is what is the brand name you use? and how may time and how many drops per day you use? Also, how long have you been without an outbreak? Also, I think that for those of you that have tried oil of oregano without results is because you were using the imitations. Please let me know as soon as possible because I want to try it.
