Is the coffee property "cold" or "hot"? Chinese medicine doctor answers
First of all, according to the theory of Chinese medicine, is coffee cold? Still hot and dry? There is a saying on the internet that coffee beans are taken from the fruit of coffee trees, which are red, belong to fire, enter the heart, and are bitter, and flow into the large intestine. Looking for China's traditional classics, I found that coffee is slightly bitter, astringent and flat according to the definition of traditional Chinese medicine. However, depending on the baking method and temperature of coffee beans, even adding ice water to make iced coffee or heating to make hot coffee, the properties of coffee will be different. So it's hard to jump to a conclusion that coffee is "cold" or "hot".
