Natural pain relief

Hello there,
I live in Montreal, Canada, but I'm originating from Romania, Eastern Europe, and in our country people use extensivly some salts and black mud against arthritis, articular pain, rheumatism. Those are pure natural products from untamed places, and it looks like they are producing a miraculous response in that process. As you probably know, using regular medication have important unfavorable side effects against vital organs as liver, kidney, and stomach, and they could even lead to a narcotic analgesic dependency.
Currently I'm on my way of importing a few samples, and if you wanna find out more about it, I will send you first all the info I've got, and then you can decide whether give it a try or not.

Health to you!
M
