Can attest to that! On my daughter's advice, I got oil of oregano. She said to put a drop under the tongue to ward off a cold. My mouth felt like it was on fire, but the cold never developed. Since then I've diluted it, and it works very well. Also, the smell is very strong. I've kept it wrapped in a sealed freezer bag, and put it in a jar.
