This plant has strong adaptability and can grow on sandy soil, thin hillside soil, black soil, and clay. It is native to India and Pakistan. It was widely planted in India about 3500 years ago. At present, cultivated Vigna radiata is widely distributed in tropical and subtropical regions around the world. Its main exporters are China and Myanmar.
This plant is very popular in East Asia, the Indian subcontinent, Southeast Asia, and the Middle East. Some desserts, wines, and beverages contain it. Its seeds are commonly used fillings for Chinese moon cakes.
After autumn, people gather mature seeds of Vigna radiata, remove their impurities, wash them with water, dry them in the sun, use them directly, or grind them into powder, and make them into Chinese herbal medicines.
