I don't know about a cure but I know Renavive works. It's all natural and contains Celery seed extract as well as chanca piedra among many other effective ingredients for kidney stones. A friend of mine had extremely painful kidney stones and took this product. I know it helped him with the pain and it also broke the stone down and flushed it out of his system. My friend swears by this product. I think the site is http://www.renavive.com
but you can just google renavive if I'm wrong. Good luck with your stones...
