Viagra, the drug designed to revive flagging sex lives, can also be used to give a new lease of life to flaccid flowers. A single milligram (50mg in a single tablet) of the impotence drug is all that is needed to give waning blooms an extra week of life.
Viagra contains nitric oxide, which slows down the dying process in plants. The same chemical relaxes the muscles in a man’s penis, allowing the blood rush which is how Viagra perks things up in men, too.
