Tiger Balm contains Camphor and Menthol, which almost everything from Vicks Vapor Rub to Ben Gay all seem to have.
But Tiger Balm also constains Capsicium. Capsicium is a pepper plant, much like cayenne pepper.
I'd once read that cayenne pepper has, for thousands of years, been used to treat pain.
I once bought pepper spray for a back problem. It worked but the fumes were terrible. I forgot about it.
Becky's back has been crippling her.
Her stride was around 1 inch.
About 40 minutes after applying a Tiger Balm patch, she was moving around like nothing was wrong.
I'd guess the effects were either psychosomatic or from the tingling sensation that pepper causes on skin.
I always thought that tingling/stinging confuses the nerves.
For whatever reason, she is much better.
