Aphrodisiacs

Human pheromones, which still carry some weight in the field of love research, may actually create sexual interest. The word "pheromone" comes from the Greek words pherein and hormone, meaning "excitement carrier."

There is still evidence that smell is an important aspect of love (note the booming perfume industry). Researchers conducted an informal experiment using identical twins. Both twins sat at a bar for an evening, and one of them was sprayed with manufactured pheromones. The result was that the twin who got the pheromone boost was approached three times more often than the twin who didn't.

Ginseng is another long-touted aphrodisiac. Recently, the Journal of Urology reported, "the Mean International Index of Erectile Function scores were significantly higher in patients treated with Korean red ginseng than in those who received placebo."
