When I feel the need
When I feel the need to cleanse I turn to CNP. I have gallstones sometimes. I have used the Gallbladder, Liver and Colon cleanse. Being comprised of liquid supplements, these are gentle. Note they are effective. About day 3 you should stay near the bathroom. Be sure to use digestive enzymes to aid food breakdown and milk thistle is a natural binder. The liquid Chanca Piedra is my mainstay for maintenance.
