Mugwort is a plant native to Europe, Asia, and Africa. The parts that grow above the ground and the root are used to make medicine.
Chemicals in mugwort might have anti-inflammatory effects. It also contains a chemical called thujone, which might stimulate the uterus.
People use mugwort for anxiety, irregular periods, colic, insomnia, and many other conditions, but there is no good scientific evidence to support these uses.
Don't confuse mugwort with plants with similar common names, including Artemisia herba-alba, tarragon, wormseed, and wormwood. These are not the same.
