Description
Shrubby perennial with long thin leaves and tiny round tufts of flowers.
Habitat & Cultivation

Parts Used
Flower heads.
Constituents
Levant wormwood contains santonin (a sesquiterpene lactone), artemisin, and a volatile oil (with up to 80% cineole). Santonin is directly toxic to roundworms and, to a lesser extent, threadworms.
History & Folklore
Levant wormwood was known to the classical Greek world as a remedy for intestinal worms, and it has been used for this purpose ever since. Its active constituent, santonin, was first isolated in 1830, and is now more commonly employed than the plant itself.
Medicinal Actions & Uses
Used almost exclusively to expel worms, Levant wormwood is strongly bitter and aromatic and has a tonic and stimulant effect on digestion. The dried flower heads are occasionally mixed with honey to disguise their bitterness.
Cautions
Do not take during pregnancy. Use only under professional supervision, especially in the case of children under 12.
