Viagra helps flowers

The pill, which helps in erection problems, prolong the life of cut flowers, scientists have discovered. One milligram is enough to keep the plants fresh a week more than usual.

One tablet contains 50 milligrams, which scientists say could double room life.

The pill contains a nitrogen oxide, which slows the withering of the plants. In humans, the same substance relaxes the smooth muscles of blood vessels, thus facilitating the flow of blood and so assist the erection.

Aspirin also prolongs the life of the flowers, but Viagra is more effective, so scientists are planning to develop “horticulture version” of the drug.
