Bananas are not a phytotherapeutic agent, but a foodstuff. Originally from Asia, bananas are also cultivated in Africa, America, India, Colombia, Ecuador, Honduras and Costa Rica and require a subtropical to tropical climate.
Bananas are important as a food because of their mineral and nutrient content, as a quick source of energy, fructose, glucose, potassium and magnesium, but also because of their allergenic potential, see cross-reaction, allergy syndrome, oral.
Bananas are also popular in baby food, as a smoothie or as an emergency substitute for hypoglycaemia - ripe bananas are preferable here.
