Summary: Liángchá (凉茶), often translated as “cooling tea,” is a traditional Chinese herbal drink originating from Southern China. Despite its name, which literally means “cool tea,” it is not defined by its temperature but by its “cooling” properties according to Traditional Chinese Medicine (TCM). Typically a dark, bitter infusion of various herbs, liángchá is consumed to combat “internal heat” (上火, shànghuǒ) caused by diet, weather, or stress. It is a cornerstone of Cantonese health culture, available both in traditional herbalist shops and as a popular sweetened beverage in red cans, like Wanglaoji (王老吉).
