Kidney Stones For some things, the zapper is not the right solution. I take a modified kidney herb tea daily. About 18 years ago, I was hospitalized for a kidney stone issue. I have not had such problems since, and I have been taking that tea. My wife makes it using only hydrangea root (see page 549 in Hulda’s book “The Cure For All Diseases”. Hulda also reports that the zapper does not reach into the gut, and for that herbs are still needed. There is also a liver cleanse recommended in the book, which purges gallstones, rather than using the common western medical approach of a surgical removal of the gall bladder.
