Eating watermelon delivers Viagra-like effects to the blood vessels in the body and may even increase libido, according to the research of Bhimu Patil, director of Texas A&M's Fruit and Vegetable Improvement Center.
Watermelons have naturally occurring nutrients that can produce healthy reactions in the body. One of those nutrients is citrulline, which is converted to arginine through reactions initiated by enzymes. Arginine is a compound known to improve blood circulation throughout the entire body.
While there are many psychological and physiological problems that can cause impotence, extra nitric oxide could help those who need increased blood flow, which would also help treat angina, high blood pressure and other cardiovascular problems.
“Watermelon may not be as organ specific as Viagra,” Patil said, “but it’s a great way to relax blood vessels without any drug side-effects.”
