Query: Great for headaches, carpal tunnel, etc

This is one of those cases of truth in labeling. They call this stuff tiger balm for a reason. I first started using Tiger Balm at the recommendation of a friend after I was diagnosed with Carpal Tunnel Syndrome. Just a dab of the balm at the base of my thumb tamed a bit of the night-time pain. A touch of tiger balm on your temples will help with a headache. Be sure to wash your hands thoroughly before you touch your eyes, mouth, etc. This is strong stuff and it does burn sensitive skin.
