Tincture of Myyrh really works. Just 1 or 2 drops on a cotton bud or q tip will heal the Canker Sore. Myyrh must be reapplied several times to be effective. How do I know this, because I have used Myyrh on Canker Sores for about 25 years. Tincture of Myyrh must be 100% natural. This can be purchased in a Pharmacy that sells Natural Products, or your local Health/Natural Food Store.
