What fruit is a natural Viagra?
Watermelon: A natural form of Viagra?
Watermelon is a natural source of citrulline. Citrulline is an amino acid that may support better erections. Viagra works by increasing blood flow to the penis, allowing a man to more easily get an erection when he is aroused. Citrulline may do the same thing, although it works in a different way to Viagra.
