Get natural pain relief with this very first product sold by J.R. Watkins in 1868. By removing all traces of artificial red coloring, we have successfully made this one of a kind pain reliever 96.5% natural! This formula puts all-natural camphor and capsicum to good use by stimulating nerve receptors that feel heat, masking the feeling of pain and relieving the discomfort of minor muscle aches, soreness and stiffness.
