I purchased mine at the Vitamin Store, just remember to buy the correct Oregano that I mentioned in my post. It comes in a small bottle and it cost me around $19.00 for the stores brand name, but it goes a long way because it is strong. Also, you can try RG's medicated cream, it is excellent also. Buy both and try each, it won't hurt you and one of them or a combination of both may help. It is certainly worth a try to get some relief!!!! My Dad mixes a few drops of the Wild Oregano and RG's cream together and applies it to his head and it takes care of his oozing leasons which he has not found anything to heal them for 17 years until now. Let us know if it helps you. Donna
