I have had RA for 18 yrs. and used numerous joint and muscle products and this, for me, has been the best.
It is called"Natures Kiss" herbal rub. They make several other sorts and are used by cyclists. Chaffe rub is one
It is not cheap but so are many of the other joint ease products and doesn't stink.
I do not have any financial interest in this. Search google. Mine is in a purple pot.
