It is said that if you rub banana peel on your teeth for about two minutes every day, minerals in the banana peel (such as potassium, magnesium and manganese) can be absorbed by the teeth, making them noticeably whiter.
Banana peels can treat skin bug bites and other skin problems such as psoriasis, all you need to do is rub the inside of the banana peel directly on the irritated area.
Banana peel will also soothe the inflammation and irritation of acne. Rub the inside of the peel directly on your face for about five minutes, then wet your face with warm water. You should repeat this three times a day until your skin improves.
