The Chemistry
Artemisia herba-alba oil is a complex mixture of monoterpenes and sesquiterpenes, including camphor, 1,8-cineole, and alpha-thujone. These compounds are responsible for its distinctive aroma and therapeutic properties. The oil is typically extracted via steam distillation of the aerial parts of the plant. Chirality is relevant as some constituents like thujone exist in enantiomeric forms with different biological activities.
