"The last 5 days I have had tendinitis pain again in my left elbow. Hurt like crazy too. As I was towing my boat to the lake today to do some fishing I put 5 drops of birch oil on the elbow and rubbed it in real good. In 5 minutes no pain. After fishing for 7 hrs and catching 75 fish, I glanced at my arm as I was driving home and said out loud and laughed when I said, "HEY, THAT ELBOW HAS NOT HURT ONE BIT SINCE THE BIRCH TREATMENT!!!!!! From now on wherever I go the birch oil will be in my pocket. That's a promise. "
