It's about to hit US shores and promises to send a woman's libido into overdrive! It's not a pill or a potion, and there's no prescription needed. It is Scentuelle - a clear, floral scented patch worn on the wrist. Makers say it's different from anything else out there because it doesn't enter the bloodstream and works on the mind instead of the body. How? Women simply place the passion patch on their wrist and take a whiff every hour. Makers say there's a reaction in the brain to the combination of scents meant to mimic the reaction to dopamine, a feel-good chemical. A leading sex expert says there is research showing dopamine does play a role in a woman's sexual energy. But, is there science behind this sticker? You'll meet one woman who says it certainly got her motor running.
