From the perspective of nutrition, banana is a kind of beneficial fruit rich in starch, but from the perspective of traditional Chinese medicine, banana is sweet and cold, which can clear away heat and moisten intestines and promote gastrointestinal peristalsis, but it is not suitable for people with spleen deficiency and diarrhea.

People with hemorrhoid bleeding and people with hot and restless fetus can eat raw banana meat.

But it is precisely because bananas are cold that people who are prone to deficiency and cold had better avoid them. For example, people with stomach cold (light mouth and bloating), deficiency cold (diarrhea and dizziness), nephritis (also deficiency cold) and swollen feet during pregnancy, it is best not to eat bananas raw. Banana meat can't be eaten unless it is cooked, and its coolness is reduced. As for colds and coughs, bananas are not edible, but it is acceptable to steam bananas before eating.

The folk prescription is more effective to treat chronic cough with banana stewed rock sugar; Cook wine with bananas as a diet. Modern medicine believes that banana can cure hypertension, because it is rich in potassium, which can balance the adverse effects of sodium and promote the growth of cells and tissues. Banana can be used to treat constipation because it can promote gastrointestinal peristalsis.

In short, people who are hot and dry can eat a banana a day, but if they are afraid of bananas catching cold, they can choose to eat banana (which has stronger laxative power) and imperial bananas.
