The secret to boosting your libido could be as simple as adding a bit of spice to your sex life—literally, according to Aussie research cited by The Courier-Mail Tuesday.

A study by Brisbane-based company Applied Science and Nutrition, in conjunction with the University of Queensland's medical school, found men taking the herb fenugreek can boost their sex drive by at least a quarter.

The trial involved 60 healthy men aged 25-52 taking a 600ml extract of the bean-like plant, which is often used in Indian curries, twice a day for six weeks.

Their libido levels were monitored to assess any changes after three and six weeks. After six weeks, their scores had soared by an average of 16.1 to 20.6—a 28 percent rise. A second group of men took dummy pills and saw their scores fall.
