Parasites can live in any organ in the human body - including the kidneys and bladder. Also - when cleansing - toxins can come out of every bodily fluid - mostly in the feces and urine - but also in sweat, tears, vaginal fluid, semen, etc.
Keep hydrated to help flush out the toxins and dead parasites better and faster. I would also recommend that you do the Kidney Cleanse after your HUMAWORM is done just to cleanse and repair your kidneys and bladder after all this hard work they have done.
