A healthy liver produces enzymes that help break down fats, etc. They also help the digestive system function properly. Many natural foods contain things that help the liver do its job - there are also supplements that do this, but I don't know much about them. Here are the herbs in HUMAWORM that will help the liver produce enzymes: Cayenne, Ginger, Gentain, Milk Thistle, Burdock, Barberry and Cascara Sagrada.
