I have tried the Clark kidney cleanse twice. I did notice that my Body Odor was almost eliminated. I did not have to use deodorant daily. Maybe once or twice a week. I also noticed that the black floaters that I had in my eyes were gone. These were the only two things I noticed. I made and drank the tea for three weeks each time. I also did a parasite cleanse at the same time. Clark now recommends six weeks. I found the making of the tea a bit time consuming and messy. It was rather inexpensive to buy and most of the items were easy to find. I sometimes found it difficult to find fresh organic parsley.
You might want to look into trying Dr. Schulze 's kidney cleansing and detoxification program. I have found it easier to make and it probably is as effect as the Clark method. His method may cost a bit more. He uses some of the same herbs that Clark uses for her cleanse. You can read about the Schulze kidney 5 day kidney cleanse here on Curezone at //www.curezone.org/schulze/herbal_5day_kidney_cleanse.asp.
He uses a combination of herbs that come prepackaged along with Kidney/Bladder Tonic. Schulze also recommends that one do a Bowel Cleanse before doing the kidney cleanse.
