Bananas are the fruit of Musa acuminata. Acuminata means long-pointed or tapering, not referring to the fruit, but to the flowers giving birth to the fruit.
The original banana has been cultivated and used since ancient times, even pre-dating the cultivation of rice. While the banana thrived in Africa, its origins are said to be of East Asia and Oceania.
Bananas can help cure or prevent hangovers. The main causes of hangovers are dehydration and depletion of potassium, both direct results of alcohol consumption.
Bananas are an excellent source of potassium (second only to the avocado) with over 450 mg. per one banana serving, as well as being high in magnesium, which can help relax those pounding blood vessels causing that nasty hangover headache.
