I've already been through a bottle of chanca piedra it didn't help with the stone I have stuck at all. I am now trying something called stone-free and am thinking about trying the Celery seed tea. I can't find Watermelon with seeds locally which is frustrating since I do like watermelon. I am drinking about 15 glasses of water a day plus a couple of glasses of apple juice with the robert gray Colon Cleanse program. No luck yet but the kidney stone has become much more annoying in the last three days so I am hoping that means it is moving its way out. I feel sort of trapped in the house, I feel like I have to urinate every waking minute of the day, whether I actually need to or not. If anyone has any other ideas for breaking a stone that's caught in the urinary tract I'm open to suggestion.
