Artemisia cina
Artemisia cina, commonly known as santonica (zahr el shieh el -khorasani), Levant wormseed, and wormseed, is an Asian species of herbaceous perennial in the daisy family.[2][3] Its dried flowerheads are the source of the vermifugic drug santonin since ancient times.[4] 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. Dysphania ambrosioides is another plant with the common name wormseed, called epazote in Mexican cuisine.[5]

The plant is characterised by its spherical pollen grains, which are typical in the Asteraceae; a fibrous layer on anthers; lignified, elongated, hypodermal sclerids; and clusters of calcium oxalate crystals.
It is native to China, Pakistan, Russia, Turkistan, Kazakhstan, and Kyrgyzstan.[6]
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.[7]
