Nopal Cactus Powder is the best thing that has happened to me for as long as I can remember! It reduced my arthritic knee pain level within one day, and in two days, the pain was gone! My husband had severe pain in his foot and the doctor wanted to prescribe topical and oral medications, and a cortisone shot. I said NO! Two days on Nopal Cactus Powder, he was walking normal. No limp! After raving about the product to co-workers, I ordered 5 bags. They love it, and are telling their friends and families. The senior citizens in my Bible History class heard me rave and this 5 bag order in going to class Friday. I even took a bag to my Chiropractor, who has an arthritic father. I'm promoting this product like I am on commission! A blast is going to all my email and Facebook buddies. Praise the Lord for Nopal Cactus Powder! Thanks Z Natural Foods!
