Description

Artemisia argyi is an upright, greyish, herbaceous perennial about one metre tall, with short branches and a creeping rhizome. The stalked leaves are ovate, deeply divided and covered in small, oil-producing glands, pubescent above and densely white tomentose below. The lower leaves are about six centimetres long, bipinnate with wide lanceolate lobes and short teeth along the margins. The upper leaves are smaller and three-partite, and the bracteal leaves are simple, linear and lanceolate. The inflorescence is a narrow leafy panicle. The individual flowers are pale yellow, tubular, and clustered in spherical turned-down heads. The central flowers are bisexual while the marginal flowers are female. The petals are narrow and folded cylindrically and the bracts have a cobwebby pubescence. The whole plant is strongly aromatic.

Uses

• Wormwood leaves are gathered on a warm dry day in spring and summer when the plant is in flower and dried in the shade. In traditional Chinese medicine, they are considered to have bitter, pungent and warm properties and to be associated with the liver, spleen and kidney meridians.
• The leaves are used as an antiseptic, expectorant, febrifuge and styptic.
• A volatile oil can be extracted from the leaves and used in the treatment of asthma and bronchitis for which purpose it is sprayed onto the back of the throat and brings rapid relief.
