Watermelon can act like a natural Viagra in the body. Bhimu Patil, PhD, told WebMD that this is because of a nutrient called citrulline, which boosts nitric oxide and relaxes the blood vessels, mirroring the effects of drugs used to treat erectile dysfunction. And of course, women directly benefit too — any time increased circulation comes into the picture, we’re talking more energy and more pleasure-inducing endorphins.
