Combining lime with Viagra can make men sharp between the sheets.
A new study has revealed that men who sucked the juice of two limes made the love drug up to four times more potent and say that the citrus cocktail will get males performing in minutes compared to the usual half-hour.
Experts claim that the lime helps to increase levels of nitric oxide which enables better blood flow after an experiment was conducted on rats.
The lime-flavoured rodents were getting randy within 15 seconds, compared to over a minute for other rats and the juiced-up creatures also got frisky with twice the amount of females.
Lead researcher Ayokunle Ademosun, of the Federal University of Technology in Akure, Nigeria, said it is the first study to show that citrus fruit can help beat impotence.
