Cantonese people don't drink herbal tea casually, but according to the season and your personal physique. It is most suitable to drink wet tea and five teas in summer. Autumn is chrysanthemum and Sydney tea. If you don't catch a cold in spring and summer, you don't need to drink herbal tea. Bansha and Shaxi herbal tea are drunk when you have a cold. You can also drink bamboo cane, carrots and horseshoe water at ordinary times. If you have a bad appetite, you can drink appetizing tea. There are many herbal tea shops in the street now, but they often add too much water and the tea is not strong. If you have time, you might as well do it yourself. Herbal tea granules and materials are sold in pharmacies and supermarkets.
