Dr Clark has a kidney cleanse which works very well to get rid of kidney stones as well, but you have to cook it into a tea that you drink for 2 weeks.
I would put each serving in a zipplock small screw on container and put into the freezer.
I would take out each days use and let thaw and drink.

My mom has had a 35cm cyst on her kidney for years and once I got her D levels up and used Serrapeptase, the cyst shrunk 4mm in 3 months. I think the vitamin D is what is really shrinking it.
She had nodules in her lungs and all of them shrunk 4mm as well.
