Mugwort: Benefits, Side Effects and Safety


Scientific name: Artemisia vulgaris Also called: mugwort, wild wormwood, felon herb, St. John’s plant, sailor’s tobacco

Mugwort is a plant found in many parts of the world. It has a long history of use in traditional medicine. Today, people use it for many different health concerns.

What is mugwort?

Mugwort is a plant native to Europe, Asia, and Africa. It now grows in North America as well. In the past, people used it for stomach and female health issues.

Today, companies sell it as a supplement for anxiety and sleep problems. They also sell it for high blood pressure and menstrual cramps. Some topical products use it for raised scars.

What are the benefits of mugwort?

Very little research exists on mugwort in people. We do not have enough evidence to know if it helps any health condition.

One small study looked at a lotion for raised scars. It contained mugwort and menthol. Because it had two ingredients, we do not know if mugwort helped.

What are the side effects of mugwort?

We do not have enough evidence to know if mugwort is safe. This applies to both oral and topical use. More studies are needed to understand its safety.

Always talk to your health care provider before using any herbal product. This is very important if you take other medicines.

The FDA does not approve dietary supplements before they are sold. Manufacturers are responsible for their own safety and labels. The FDA can only act if public health concerns arise.
