Magnesium salicylate
"I strongly recommend that everyone uses this product. I am a very skeptical person when it comes to putting anything in my body, which is why I am so paranoid when it comes to many products. DeWitt's Pain Reliever though is handled by a 100 year old company though and that gives me a sense of security. For the effectiveness of this product, I can't give it anything less than 5 out of 5 stars because it has become my new aspirin. I use it for headaches and soreness all the time!"
