A TCM "eye-nourishing" staple from Anhui’s cassia seed plantations—valued for its cassiaside content. It supports eye health and gentle digestion, making it a critical ingredient in dietary supplements (eye care, laxatives) and functional foods. 

Exported to Southeast Asia for eye and gut health products, its global demand grows 15% annually. 

China’s large-scale cultivation ensures stable supply, and its role in eye health will drive demand as digital eye strain rises.
