I just got my $40 jar of Purple Rub Pain Relief Cream in the mail and I couldn't slather it on my knee and new bruises fast enough. Cycledelic Neophyte had a jar of it at Dirtweek and let me use some of it after I crashed on my knee. I couldn't believe the difference in the reduction of stiffness and general ease of pain in the knee joint. The next morning I was knocking on hers/KelvinKDX's trailer door at 7 am begging for some more of that stuff to get me through the day! This stuff has emu oil in it, supposed to be very therapuetic. Its a little steep in price, but I think its worth it. Definitely a step or two above ben-gay and blue ice type creams.
I put some on a very deep truamatic bruise I have on my calf/shin. I've had this bruise for a couple of weeks and it started to break up the color and the swelling that were still present within a couple of days. I think KelvinKDX said he used it for his back trouble as well with positive effects.
