As an X-ray tech for over 20 years I have filmed a gazillion kidney stone patients but never had them myself until one day...I passed 31 stones total but the last one (a huge stone at 6mm) sat stuck half way down my ureter causing severe pain and nausea for one week despite the medicines the ER doctor prescribed to get the stones to pass. I found this awesome product on-line and decided to give it a try. I took the pills at 4:30 PM and by 9 AM the next day I had finally passed the last stone! I continued to take a maintenance dose for the following week just to make sure all the stones were gone. No issues since. I love this stuff! It works and now I'm spreading the word to anyone who has ever had stones to help them pass them quickly! I've seen far too many people in immense pain in the hospital and unfortunately the medical society frowns on natural intervention. If you have stones...try it...save yourself the pain and frustration. This stuff works!
