Watermelon May Have Effects Similar to Viagra One of watermelon's ingredients triggers production of a chemical that works similar to Viagra. And the millions of watermelons being enjoyed across the nation this summer just might help men get their groove back.

In fact, the ingredient, citrulline, might not only treat erectile dysfunction but also help prevent it. In the body, citrulline is converted to arginine, an amino acid known to improve the heart and circulatory system and to boost the immune system. It helps erectile dysfunction by relaxing blood vessels, similar to Viagra's effect. Arginine boosts nitric oxide, which relaxes blood vessels, the same basic effect that Viagra has, to treat erectile dysfunction and maybe even prevent it.

The more research done on watermelons, the more we learn just how amazing a fruit it is in providing natural enhancers to the human body. Watermelon may not be as organ-specific as Viagra, but it’s a great way to relax blood vessels without any drug side effects. We’ve always known that watermelon is good for you, but the list of its very important healthful benefits grows longer with each study.
