I found out about this product from my grandmother. My favorite is the green one. Which is hard to find these days.
I purchased this for my headaches and to use when my nose was stuffy.. When I had a headache or sinus issues, I would rub some on my forehead. It would help tremendously. It would burn a little, but boy did it help.
Also when my nose would be stuffy from sinuses, I would put a dab on a tissue and breathe in. It would clear up my sinuses where I could breathe again.
