Hello there,
I live in Canada, but I'm originating from Romania, Eastern Europe, and in our country people are using extensively some special salts and black mud to fight against arthritis, articulary pain, rheumatism. Those are pure natural products from untamed places, and it looks they are producing a miraculous effect in that process.
As you probably know, the use of regular medicine has often important unfavourable side effects against vital organs as the liver, kidneys, 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 want to find out more about it, I will send you all the infos I've got, and then you could decide whether giving a try or not.
Health to you!
M.
