It is said that herbal tea originated in Guangdong. Because it is located in Lingnan, the weather is hot and humid, and it is easy to get angry. Therefore, people adopt the concept of health preservation in traditional Chinese medicine, and boil water into tea with cool medicinal materials, which has the effects of clearing away heat and toxic materials, quenching thirst, removing fire and removing dampness, among which bitter herbal tea is also called bitter tea. Because herbal tea has the effect of relieving summer heat, it naturally spreads to the south where the climate is hot, to Hongkong, Macau, Taiwan Province, Malaysia, Singapore and other places.
