Chinese medicine points out that mugwort leaf is not only a common vegetable, but also a practical medicine.

In order to cure diseases and ward off evil spirits, there is also the custom of eating mugwort leaves on March 3, hanging mugwort leaves at the door on May 5, and washing mugwort leaves with medicine bath.
