It’s best used in dried form, which contains little, if any, thujone. To make a wormwood infusion or tea, steep a half teaspoon to one teaspoon of dried or fresh wormwood in one cup of boiling water for five to 15 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 tea, but also a more bitter tea. Wormwood should be taken unsweetened to have the best effect, but you can counter the bitterness by adding dried peppermint or anise.
