This little miracle worker is WONDERFUL! I have bad knees and I'm on a prescription from the doctor. When my job requires me to be on my feet for hours, my knees will be killing me. I tried this just to see what would happen. INSTANT HAPPINESS happened. It took a lot of the pain away so that I could do my job. It's not greasy or messy. It doesn't stink. I can feel my knees hours later and know that the salve is still on and working. If I don't feel the salve (the salve feels dry by the way when I touch my knees) I know I need to add more. I use it twice a day -morning and night when I know I'm going to be on my feet a lot. I even took this little baby on vacation with me. We do a lot of walking on vacation. It's small so it easily fits in your purse or even your pocket. I'm so glad I found out about Prairie Star!
