The Chinese herbal tea or cold tea is a drink concocted from medicinal herbals to ease the summer heat in human's body or sore throat caused by the dry winter.

Drinking herbal tea is an age-old custom in Guangdong province, Guangxi Zhuang autonomous region, Hongkong and Macao Special Administrative Regions, where the climates are damp and hot and people living there easily suffer from excessive internal heat. In order to repel internal humidity and heat, people collect herbs which can clear away heat and dampness from mountains and valleys to concoct into herb tea.
