If you suffer from achy back pain, arthritis, tendonitis, fibromyalgia, etc....give 100% Tart Cherry Juice a try. Even if you are apprehensive to trying anything natural for pain, I think you will be pleasantly surprised! I am amazed at how much this juice helps to relieve my severe back pain. I only drink one large gulp a day. It must be 100% Tart Cherry, not the cherry fruit juice you find in the Welch's juice aisle. This will be found at a health food store or at your local grocery store in the organic section. I get mine at Trader Joes. Give it a whirl!
