Insect tea, a wonderful work in the Chinese tea culture

Insect tea, listed in the “Compendium of Materia Medica” by Li Shizhen, is not only a traditional drink for the ethnic minority in southwest China, but also one of China's traditional export commodities. Insect tea is made of the feces of insects that feed on plants, and characterized by minimal dose, enjoyable tea flavor, few tea-residues, and superb transparency. Insect tea has been used to clear summer heat, protect the spleen and stomach, and facilitate digestion.
