History: Artemesia vulgaris was named for Greek goddess Artemis, and was introduced to North America in the 1800’s for a variety of medicinal purposes. It is currently considered to be invasive in most parts of the US and Canada. In traditional Chinese medicine, its dried leaves are burned on the skin to stimulate acupuncture points for treatment of rheumatism and was also used for correcting the position of breech births. In traditional European medicine, a tea made from its leaves was used to treat epilepsy, menstrual, menopausal and gastrointestinal problems and to increase the flow of urine and stimulate the appetite. It has also been used for centuries to repel insects, especially moths, from gardens. An infusion of the leaves and flowering tops has been used in the treatment of nervous and spasmodic affections, sterility, asthma and diseases of the brain. The plant also plays an extensive role in witchcraft practices and continues to be used in a variety of European and Asian cuisines. In Japan, the young leaves are used as a potherb and its dried leaves and flowering tops are steeped into tea. Its cooked leaves is said to aid in digestion of fatty foods. It was used to flavor beer before hops took over that role. Its pollen is an allergen and can be a major cause of fall hay fever.
