Artemisia Douglasiana

Scientific Summary

Artemisia douglasiana is a perennial, aromatic shrub whose leaves and dried herb are traditionally ground into a tea or tincture. It is mainly used to help reduce fever, ease digestive troubles such as indigestion and flatulence, and calm coughs or mild respiratory congestion. Because the plant contains volatile oils—including thujone—a high dose or prolonged use can irritate the digestive tract, strain the liver, and may interact with anticoagulants; it is advisable to use it sparingly and to avoid use during pregnancy.
