Well, I went to the Vitamin Shoppe last night and got my bottle of Oregano Oil and forgot this one little tidbit of info you gave. Darn it! My bottle says "proprietary blend" on it. I put it on the spots last night. They tingled, but certainly not enough that I felt I had to remove it. I even did a second application before bed and I woke up looking no different. Now I'm on an online quest to find what you recommended in the first place.
