Fructus momordicae, called Luohanguo in Chinese, is primarily grown in southern China's Guangxi Province, with the majority coming from the mountains of Guilin. In China, traditional Chinese doctors have used Luohanguo as an expectorant, to fight heat stroke, acute or chronic throat inflammation, aphonia, and chronic cough for centuries.

It has been reported that the residents who live near in Yongfu and Lingui Counties (of Guilin), are recognized as having an unusually high number of residents living to an age 100 years or more. Some people attribute this to the consumption of Luohanguo.

The dried fruit may be bought in almost all the Guilin markets. The outer surface of the dried fruit is round and smooth, dusty yellow-brown or dusty green-brown. It is covered with fine, soft hair. The fruit is covered by a hard but thin skin. The entire fruit, including the seeds, have a nice sweet flavor. Luohanguo is best steeped in tea.
