Be reactive by accepting that parasites exist and that you probably have them. This means adopting an ongoing parasite cleansing program, not a one-time only cleansing program. Although natural and herbal remedies abounded in earlier times, drugs are now generally prescribed for parasites. Unfortunately, many drugs are not as effective as they once were. According to Louis Parrish, M.D., Flagyl, a first-line killer of protozoa, is only 5 percent effective.
Most drugs also come with a long list of side effects.
A more natural way to combat parasites is to use an herbal remedy. Dr. Weintraub agrees. Herbs have been used for centuries to treat parasites. Endogenous people have always used something local to help with whatever was bothering them. Some of these herbs include garlic, wormwood, yellow gentian, grapefruit seed extract, butternut, and black walnut.
