The cleansing link at the top will provide some information. Barefoot Herbalist sells a Kidney Cleanser. Others may sell something as well. At different times, I used dried parsley (for tea), fresh Watermelon and ground Celery seeds (tea). The dried parsley was, by far, the best for me. I'm going to do another one after I complete my 7 day Liver Flush (eggs, lime, and oo).
