Did you know: 'Gentlemen's medicine' Viagra was born just because of an accident?

Viagra - the name was so familiar that even though it was not used, it was heard. However, this kind of "medicine for men" has an odd birth.

Medications to relieve angina . "medicine"

Born in 1998, so far, Viagra is still the super-money making machine of the pharmaceutical company Pfizer. According to a report, only in 2012, Viagra's revenue reached $ 2 billion.

The most unexpected thing is, Pfizer has never had any intention of manufacturing (or "impotent" ).

Viagra - the most famous medicine god of men.

Pfizer researchers are currently testing a batch of medicine to treat angina . They want a drug that can relax blood vessels. However, this test quickly brought disappointment, when users responded that they had side effects in an extremely . difficult way to say.

That is, the gentlemen fall into the "12h" state after taking the medicine.

Later tests showed that this batch of drugs has the ability to inhibit the production of an enzyme that weakens an erection. It means that after taking the medicine, you will not be able to "leak" until the medicine is no longer effective.

After that, Pfizer changed the name of the medicine into the drug , and the drug quickly became extremely popular among the public.

Before 1998, no medicine was available to treat erectile dysfunction.

Before Viagra was released in 1998, there was never a single medicine that could cure erectile dysfunction. The less fortunate can only improve the situation by injecting drugs directly, or having surgery for . permanent erection.

In short, thanks to the failure of that year of angina medicine, now that the eyebrow has an option, Viagra has become one of the most widely consumed drugs in the world.

"Medicine" is not just for that!

Viagra is not only the end of men but also the "hero" in the plant kingdom. The most shocking evidence of the effect of Viagra on plants comes from Ya'acov Leshem, an Iranian scientist who specializes in flower research.

He had a hunch that Viagra would have the same miraculous effect on plants, so he put some medicine in the vase. As a result, he found that flowers keep freshness longer than usual.

"The flowers look fresh, the color and the softness last longer,"said Leshem.

In a similar conclusion, Professor Steven Neill at the University of West England in Bristol said: "The global water shortage will be a major environmental problem in this century, so anything improves efficiency. The use of water in plants becomes attractive ".
