How does rubbing alcohol soothe muscles?
I always thought it was just to prevent infection on the surface of the skin, but I read my bottle today and it claims it soothes muscles. How can it do that?
its a rubefacient - it causes small blood vessels in the skin to dilate. Most muscle aches aren't directly in the muscle, but in the fascia directly beneath the skin - idea being that helping the circulation to the skin might help the layer underneath. If it is alcohol with wintergreen in it (usually it is green) then the wintergreen is a topical analgesic (pain relieving medication)
