The tried far infrared in my amethyst bio mat,Profession mat recommended by My acupuncturist had wanted to try hers on me and we finally did. I was pain free for an hour and then more and more time. My husband said if that gave me even an hour of pain free a day it was worth it to get a personal loan and get one. It is by the Richway Company. It helps my back, legs, arms, bursitis, kept my shingles at bay and they were very mild,that was a goodness. Even my dog lays on it for the arthritis in her front limbs. It has been a miracle for me and I advise it for everyone. The Richway Company Biomats and has been around for a long time. Check it out.
It has changed my live and can't say enough good things about them, mine specifically also has 30lbs. of amethyst in it. Never thought I could be pain free for hours now.
