Iāve been amazed at the instant relief Iāve gotten from this salve. My left arch is quite collapsed and my ankle has been bothering me quite a bit lately, so I decided to try the sample sized Strains & Sprains salve on it. Wow! Instant relief! It lasts for hours, too, so Iāve only needed to use the salve three times a day. I ordered a 2 ounce salve and and loving the relief Iām getting.
