Overview
Wormwood is a perennial herb famous for its intensely bitter taste and aromatic silvery-green foliage. It is the key ingredient in absinthe liqueur and has been used medicinally for thousands of years. The plant contains thujone, a compound with neurotoxic potential at high doses, requiring careful use. It is one of the most powerful bitter digestive herbs in the herbal pharmacopoeia.
Traditional Use
Wormwood has been used medicinally since ancient Egypt, where it was mentioned in the Ebers Papyrus. Ancient Greeks and Romans used it for digestive complaints and as an antiparasitic. Medieval European herbalists valued it for expelling intestinal worms (giving it its name), stimulating digestion, and treating fevers. It was a key ingredient in traditional bitters and digestive liqueurs. The plant was also used in traditional Chinese medicine and Ayurveda for similar purposes.
Key Active Compounds
Thujone
A monoterpene ketone that is the primary active and toxic compound. Stimulates digestion in small doses but causes neurotoxicity and convulsions in large doses.
Absinthin
An intensely bitter sesquiterpene lactone that stimulates bile production, digestive secretions, and appetite.
Artabsin
A bitter compound with antiparasitic properties, contributing to wormwood's traditional use against intestinal parasites.
Flavonoids
Including artemetin and casticin, providing antioxidant and anti-inflammatory properties.
