Wormwood has been used for year to to eliminate intestinal worms, including pinworms, roundworms and tapeworms. Pinworms are the most common worm infection in the U.S. with pinworm eggs spread directly from person to person. It’s best used in dried form, which contains little, if any, thujone. To make an infusion, follow this wormwood tea recipe: * Steep a half teaspoon to one teaspoon of dried or fresh wormwood in one cup of boiling water for 12 minutes * It’s important that you use no more than one teaspoon of the leaves as they’re very strong and bitter. Longer steep time will make for a stronger wormwood tea, but also a more bitter tea.
