There is stiff competition for generic viagra and a stiffer one for Viagra. Researchers in a University at Texas have confirmed that watermelon does have erectile properties that are having water melon by men will help them get a harder erect organ. This news is better for those men suffering from erectile dysfunction. The nutrients present inside watermelon increases the sexual drive by stimulating the blood vessels. These nutrients are beta carotene, citrulline and phytonutrients such as lycopene. The benefits of individual nutrients are still going on but it is confirmed that watermelon which encompasses all these nutrients has a Viagra like effect. The chief researcher stated that the arginine boosted the release of nitric oxide essential for the relaxation of blood vessels which will aid the ED affected man. Regularly eating watermelon may also prevent erectile dysfunction for life. Hence we have a natural replacement for Viagra and generic viagra.

The weird competitor for both Viagra and generic viagra may be caterpillar fungus. It is a known aphrodisiac in Chinese medicine. It also goes by the name of Himalayan Viagra and has been always popular for the people dwelling in these mountainous regions. Apart from increasing libido and giving hardness to the male reproductive organ for coitus, the Chinese traditional medicine is also used against cancer and as a performance booster for athletes. This fungus is formed when the Ghost Moth species of caterpillar has a parasite infection and the caterpillars retreat underground where they get mummified. These mummified bodies are then harvested for their medicinal purposes. The demand for this medicine is so high that people are actually raking in the moolah. However the ecologists have raised concern over the over harvesting of these caterpillars as it is damaging the stability of the ecology.

What needs to be seen is how long Viagra and generic Viagra can outlast the natural and the weird replacements.
