I read that they are also anti-parasitic, but that they are also useful in detox:

"Metaline is an ensemble of pumpkin seeds, okra, rhubarb root, capsicum, peppermint and dulse. It is designed to clear metals from the system and decrease our toxic load by increasing the body’s eliminating abilities. Capsicum, rhubarb and okra support healthy intestinal function while dulse and pumpkin seeds assist the drawing qualities of the urinary system. Peppermint may improve bile flow, which is one of the liver’s detoxification mechanisms."
