I have been experimenting with the idea of using heat creams to aid in muscle recovery for some time now. The idea here is to generate heat to unrecovered muscle, increase blood flow and drive nutrients to the area quickly. I have been applying heat cream a couple of times a week to body parts that I happen to hit hard and definitely see an increase in recovery time and a decrease in DOMS. The only issue I see is that methyl salicylate , the active analgesic ingredient in heat creams, is toxic to the body.
Thoughts?
