Lemon juice, parsley tea, celery tea and green tea are great for passing kidney stones.
I have kidney sand often and I have had kidney stones once before. I know how painful it is and that one can do anything to get rid of it. I was able to treat my kidney sand and stones with lemon juice, green tea and parsley.
When I start experiencing kidney pain, I take a large pot of clean water and boil it. I add washed fresh parsley and green tea in it and allow it to boil nicely. Afterward, I let this water cool and add fresh lemon juice before I drink it. I drink a large glass of it every morning and night. I also drink a lot of water throughout the day.
I usually pass kidney sand in under a week when I do this.
