Watermelon, America’s all-time summer favorite, delivers more than just a juicy cool-down. According to a Texas A&M University study, the summer fruit may enhance libido in much the same way that Viagra does.

“The more we study watermelons, the more we realize just how amazing a fruit it is, in providing natural enhancers to the human body,” says Bhimu Patil, Ph.D., director of Texas A&M’s Fruit and Vegetable Improvement Center, in College Station. Bhimu and his fellow researchers have discovered that a special nutrient in watermelon, called citrulline, has the ability to relax blood vessels, similar to the action of common male sexual enhancement drugs.

How does it work? When consumed, the body converts the citrulline to arginine, an amino acid that works wonders on the heart and the circulation system by boosting nitric oxide, which in turn relaxes blood vessels, conferring basically the same effects Viagra does in the treatment of erectile dysfunction.  Although watermelon may not be as organ-specific as Viagra, it is still a great way to relax blood vessels. Even better, watermelon has none of the drug’s side effects.
