There are many herbs that are used for cleansing the 2 million cells of each kidney. Many just make you urinate allot, these may not be too good if your full of calcium, etc.
When I read Dr. Clark's books and seen her kidney cleanse herb formula, I then looked at Dr. Chritopher's kidney formulas and they were pretty close, Christopher's being a little stronger. So I made Dr. Clark's formula in a formula, not a tea as she suggest, I didn't think anyhting of it. Then i find out that drclark.com never has reorders on this expensive bunch of herbs because no one likes making it the Dr. Clark method in daily tea for 6 weeks. The version I made in a 8 ounce bottle is quite potent even taste wise too, when taken 1 tsp, at bedtime, 6 days per week for 6 weeks, one bottle works perfect. It also has had many amazing results, everything from spurs dissolving to peeing of burning sand etc.
Dr. Clark made allot of herbs noted once again, you will notice that most formulas have similiar herbs. The reason some work and some don't usually is based on the doseage and if the herbs were any good in the first place. The people that own drclark.com has purchased my version of Dr. Clarks kidney cleanse tea for the past 5-6 years, yet sell the expensive herbs that must be made as tea. When an author makes a herb famous in the book, people don't like to change the way it is described to be made! I prefer to make it the easist and best tasteing if possible.
If people are poor, I tell them to just make parsley tea.
