Fortunately, substances that do this are easily found. Psyllium, a type of soluble fiber, is an excellent intestinal cleanser. Because it is soluble it carries water and can help lubricate and loosen encrusted matter. It also absorbs other toxins and waste materials and escorts them out of the body. Psyllium, and other fibers, is an important part of any detoxification program.
Herbs are also important in detoxification.
Gentle, natural laxatives, such as cascara sagrada, soften caked food, making it easier to eliminate. Black walnut hulls also help do this, as well as having the extra advantage of being an antiparasitic. Marshmallow and shavegrass are classified as lithotriptics by herbalists, which mean that they dissolve and discharge urinary and gallbladder stones. Drinking a lot of water is also important. Water flushes toxins and waste from the body and transports nutrients to where they are needed.
