I realize this has worked for a lot of people, but I now think it is very dangerous. First of all, once you realize you have a kidney stone, remember that you do not know the size of it, where its lodged, or what you're dealing with. That is unless you get scans to find out. I currently do not have health insurance, and so a month ago when I was in the worst main of my life - vomiting, having what felt to be birth contractions, screaming in 10 pain for a month straight. The ER turned me down. Let's not go there as to why. Basically, I live in a small town where the hospital is completely incompetent.. I was on my own to figure out what to do because of nowhere to get help.
I tried the olive oil/lemon method, as I was fairly certain that what I was facing was stones. What happened is it dislodged and re-lodged somewhere else, got stuck, and put me in life-threatening pain. There were mornings I think I left my body, ready to die.. Gray/white as a ghost and unable to get up. After dealing with the incompetence of the ER once, I wasn't going to do it again.. The lemon juice/olive oil made my condition SO MUCH worse.. I simply can't recommend moving something around with oil when you have no idea where it's going to re-lodge or go. It may not always channel out of your body smoothly.
Finally, I read that magnesium was powerful at breaking up calcium-rich stones. After 1-2 weeks of taking magnesium (CALM brand) powder (stirred into 12 ounces of water twice daily), the pain diminished, and finally, a PEA (maybe larger) sized stone was released. More pieces came throughout the week. Now I'm healthier than ever.
USE MAGNESIUM to break up the stone, not Olive oil/lemon juice.
