The plant is cultivated for its fruit, whose extract is nearly 300 times sweeter than sugar and has been used in China as a natural low-calorie sweetener for cooling drinks, and in traditional Chinese medicine to treat diabetes and obesity.

The plant is most prized for its sweet fruits, which are used for medicinal purposes and as a sweetener. The fruits are generally sold in dried form, and traditionally used in herbal tea or soup.
