One other supplement to take is MSM. It is antifungal and antiparasitic.

Use raw garlic and chew it well before swallowing. Eat it after a large meal, and wash it down with plenty of water. Don't eat too much at once. One clove(section) after a large meal is plenty.

Garlic pills, especially deoderized ones are much less potent than raw garlic.
