Recently the drug flibanserin from Boehringer Ingelheim, nicknamed the "pink Viagra," designed to boost sex drive in women — the latest attempt by the drug industry to find a female equivalent to Viagra — failed in two studies. The drug was aimed at premenopausal women with lack of sexual desire, a market that drug companies have been targeting for more than a decade since the blockbuster success of Viagra in men. The search for so-called "female Viagra," has proved elusive though, with many drugs abandoned after showing poor results. Fortunately, there are several natural herbs and combinations that can improve a woman's desire. Some of these include muira puama, maca, mucuna pruriens, tribulus terrestris, tongkat ali and Passion Rx. The over the counter hormones DHEA and pregnenolone can be used for brief periods to increase libido.
