A herbaceous subshrub of the Asteraceae family cultivated for its anthelmintic properties. Also called Semen Cina. It grows to about 70cm tall, with woody stems at the base, alternate leaves, deeply pinnately lobed twice, linear, blunt lobes, and hairy, gray-green color. The stems branch at the top and produce small spike-like flower heads, with yellow glandular dots on the involucre. It flowers in late summer. The buds just before blooming are called Chinese wormseeds (English names: wormseed, levant wormseed). Dried wormseed contains about 2% santonin, and is used as an anthelmintic for roundworms.
