Reading the bitterness
Liangcha (cooling tea) is a collective term for herbal drinks of the Lingnan region (southern China, including Guangdong and Guangxi) made by decocting or infusing plant materials not limited to the Chinese tea plant (Camellia sinensis) in water. An ethnobotanical survey of 12 sociolinguistic groups and 300 people in Lingnan conducted from 2010 to 2012 recorded it as a drink made by extracting diverse parts, including leaves, fruits, flowers, bark, seeds, and roots, from one or more species in water. Because the subjects covered as many as 238 taxa, the term does not refer to a single recipe. The same survey states that gathering and cultivating liangcha have cultural and economic value and that its consumption has become part of Lingnan regional culture and lifestyle. How bitterness is softened and discussed is also part of the region’s liangcha culture.
The art of preparing liangcha was registered in 2006 as a traditional craft belonging to Guangdong Province in the first group of China’s national-level intangible cultural heritage. However, this registration indicates cultural status and does not guarantee the safety or effects on the body of individual products. It has also been recorded that producers and distributors of market products began adding sweeteners to soften bitter flavors, but their types and amounts, and how much bitterness they actually suppressed, have not been measured. A cultural article posted on the Guangzhou municipal government website in 2023 introduces local elders’ account that liangcha bitterness is divided roughly into three grades, with higher grades having heavier flavor and darker color, but this is not a standardized scale and has not been confirmed by a reproducible survey.
