"One particular kidney cleanse, the Watermelon Cleanse, maintains strong claims to rid the excruciatingly painful kidney stone in a day! "Watermelon juice, Watermelon itself and Watermelon seeds are all diuretic and disinfecting [Dr. Schultz]." Juice the whole watermelon including the seeds and rind. Watermelon rind has minerals and the seed is commonly known to be cleansing to the kidneys. Of course you don't have to sit in a bathtub to cleanse with watermelons, but I hear if one has kidney stones one just might. You might have watermelon for dinner, juice it, or fast on it for the day. Be creative, experiment and have some fun juicing. The "urinating fire" definitely provokes my interest to want to try it and see for myself and repeat it if I thought it was dong some good"
