Garlic (allium sativum) is an herb that is so powerful and multifaceted as a healer, scientists have considered labeling it a drug. It has been used traditionally to treat a variety of parasites; for instance, garlic is so powerful that it can kill roundworm, pinworm, tapeworm, and hookworm. Garlic’s ability to kill these bothersome parasites have been confirmed by scientific studies and much research.
Dosage information: 2 or 3 raw cloves of garlic per day; or three 500 to 600 milligram capsules of powdered garlic per day (look for products that supply a daily dose of 4000 to 5000 micrograms of the active ingredient allicin).
Caution: Do not use if you have stomach irritation, if you will soon have surgery, or if you take the blood thinner warfarin. If you’re on insulin, check with your doctor, as garlic can lower blood-sugar levels.
Tip: Grapefruit seed extract can be helpful in fighting both bacterial and parasitic infections. It is made from the seed, pulp, and inner rind of grapefruit. Test-tube studies show that it inhibits the growth of giardia and amoebas. Dosage varies widely; follow the manufacturer’s instructions.
