Query: Seriously, this stuff is magic.

I have rheumatoid arthritis, and my pain medication doesn't quite cut it. I picked up a jar of this stuff and it's like magic! I rub a tiny film on the aching joint and the pain is nearly instantly gone. Depending on the intensity of the ache, sometimes a dull ache is left behind, but it's a huge relief from the crippling arthritis pain.The scent of the product is something like chai tea mixed with a bit of menthol. I was worried a bit at first that people would think I smelled weird, but I've come to like the scent, and my friends have assured me it doesn't smell bad. Also, it's not greasy. The balm has a redish tint to it, so I rub it into my skin until the tint is gone and it's like my skin absorbs it. There's no grease or film left behind to rub off onto clothes or anything else.I can't believe how quickly and how well this stuff works. I now keep the jar in my purse to use whenever I need it, and I'll continue to buy this product.
