the so-called herbal tea refers to the Chinese herbal medicine which is cold in nature and can dispel the internal heat of the human body, so as to eliminate the summer heat in the human body or treat the sore throat and other diseases caused by dryness in winter. Eating hot pot, crayfish, spicy fish and barbecue, many people always turn their attention to herbal tea at the same time when they encounter food that may cause internal fire to rise. The general function of herbal tea is to clear away heat and toxic materials, clear lung, moisten dryness and relieve summer heat. For Cantonese, herbal tea can be said to be "life comes from water and health comes from herbal tea". The herbs used in making herbal tea can effectively remove toxins from human body, improve human immunity, resist infection of bacteria and viruses, balance yin and yang, and soften skin. In addition to clearing away heat and toxic materials, herbal tea can also remove dampness, promote fluid production, clear fire, improve eyesight, dissipate stagnation, reduce swelling, etc. It can also treat red eyes, headache, dizziness, tinnitus, furuncle, swelling and hypertension, and can be used as a cool drink in summer.

Another saying is that herbal tea is a general term for the liquid part of cooked Chinese medicine in Guangdong and Guangxi. Compared with some traditional Chinese medicine teas aimed at specific diseases, herbal tea generally refers to traditional Chinese medicine that can be drunk by ordinary people with the efficacy of clearing away heat and reducing internal heat.

Herbal tea is not tea, but a decoction made from Chinese herbal medicines. Herbal tea is not necessarily cold, but it is better to drink hot, and the most representative one is spot sand herbal tea.

In fact, herbal tea is the most effective and direct way to get rid of summer heat and internal heat. Some experts even predict that herbal tea is expected to become the only national beverage in China that can compete with Coca-Cola.
