Cassia seed extract is obtained from the mature seeds of Cassia obtusifolia or Cassia tora (Jue Ming Zi) through aqueous-ethanol extraction. The extract is rich in anthraquinone compounds including chrysophanol, emodin, obtusin, and aurantio-obtusin.
In traditional Chinese medicine, cassia seeds are used to clear liver heat and improve visual acuity. Modern research confirms hepatoprotective, mild laxative, hypolipidemic, and antioxidant properties. Commercially, the extract is applied in eye health supplements, liver support formulations, and herbal tea blends.
