Artemisia cina, commonly known as santonica (zahr el shieh el -khorasani), Levant wormseed, and wormseed, is an herbaceous perennial of the daisy family. Its dried flowerheads are the source of the vermifugic drug santonin since ancient times.[1] Its common names arise from its known ability to expel worms. The powder is grayish-green in colour with an aromatic odour and a bitter taste.

The plant is characterised by its spherical pollen grains, which are typical in the Asteraceae family, a fibrous layer on anthers, lignified, elongated, hypodermal sclerids, and clusters of calcium oxalate crystals.

It is native to China, Kazakhstan, and Kyrgyzstan.[2]

Biochemistry

In addition to santonin, the above-ground parts of the plant contain betaine, choline, tannins, pigments, and an essential oil. The essential oil is largely composed of 1,8-cineole, but contains a wide variety of other compounds as well.[3]
