Conditions such as erectile dysfunction are treated with synthetic drugs, including sildenafil (commonly sold as Viagra) and tadalafil (Cialis)—but these drugs can produce negative side effects such as headache, muscle pain and blurred vision, and can have dangerous interactions with other medications. They also do not increase libido.
Marcone and master's student John Melnyk examined hundreds of studies on commonly used consumable aphrodisiacs to investigate claims of sexual enhancement, either psychological and physiological—results of their study appeared in the journal Food Research International. Here's what they found:
Ginseng, saffron and yohimbine, a natural chemical from yohimbe trees in West Africa, improved human sexual function.
Wine and chocolate, improved sexual function, but their amorous effects are likely psychological.
Spanish fly and Bufo toad—while purported to be sexually enhancing, they produced the opposite result and can even be toxic.
