Western mugwort has several medicinal uses. It excites gastric juices and bile secretion. Therefore, it is useful in dyspeptic ailments accompanied by a lack of appetite, and in gastric atony. Its antispasmodic action helps alleviate pain caused by hepatic colic in gallstone cases. It has been used since ancient times to regulate menstruation in women who experience a difficult and painful period. In Mexico, the Huicholes drink juice made from the leaves to treat abdominal pain. The indigenous people of Quebec used the plants native to the area, Artemisia canadensis and A. ludoviciana, to prepare a stomachic and vermifuge infusion, as well as poultices used for treating burns. In Europe Artemisia was used as a powerful amulet against evil spells. The flowers and the leaves were also used to make perfume against demons.
