[YEA] I am a regular reader of earth clinic and am very grateful for all the information. I am thankful that I am able to contribute to this forum. I recently discovered Oil of Oregano (100% vegetarian). My internet search revealed that Oil of oregano was used to sterilize surgical utensils back in the 1950's and has been found to be useful in fighting infections that are resistant to penicillin. It is also said to be useful in treating sinus infections, bladder infections, candida and lung infections.
