May be good for sex – Citrulline is the special nutrient in watermelon that gives rise to arginine. One gram of watermelon flesh contains 1.5 mg of citrulline. When citrulline is converted to arginine, this can lead to the relaxation of the blood vessels, which is the same basic effect of drugs for erectile dysfunction like Viagra and Andros. Watermelon may not be as potent as these drugs, but it can still help the heart, brain and male sexual organ, too. And watermelon comes without the drug’s side effects.
5. Your source of alkaline water – The good news is that watermelon is made of 92% pure alkaline water. A lot has been said about the possible benefits of alkaline water. Compared to the acidic juices of oranges and pineapple (which may irritate people with ulcer and gastritis), watermelon is safe for your stomach.
6. Good for the mouth and digestive tract - Watermelon has health benefits for the whole digestive tract, starting from the mouth, esophagus, stomach and intestines. Watermelon can relieve the pain of people with singaw or mouth sores. Some experts claim that watermelon can also minimize bad breath. And as it goes down to the intestines, it can treat constipation and normalize your bowel movement.
