Yes on some injuries it does create heat.
But I'm not sure the "taste" is a contact issue.
I never wear gloves and never get the "taste". But I was born without the sense of smell. So I wonder is it a contact or is it a strong aroma.
It works great and for people too. Sunday tore the ligaments in my hand with 2 compound fractures. Have used DMSO for 4 days swealing gone 90% use of hand,BEST thing pain free-Well can feel no pain/pressure/feelings really.
Not one for being sidelined with an injury. Probably the "crazy" event rider in me.
Before everyone jumps on me, I'm sure its causeing other issues, so does everything else in life.
Quit smoking-so maybe this is my bad habit.
