Many plants are believed to be natural aphrodisiacs:

" Kilham focuses on 10 hot plants (see box) he says can restore desire, function and response, though other herbalists have their own favorites.
He met with traditional herbalists and medical researchers in such countries as Malaysia, Africa, Russia and China.

Some of the plant substances he touts have been subjected to scientific scrutiny, but he says proof for most lies in their safe use by "millions" of people over centuries.
That view is echoed by Mark Blumenthal, executive director and founder of the American Botanical Council in Austin, Texas, an independent nonprofit organization that researches and provides education about herbs.

"The overall bottom line is there is a growing body of both scientific research on animal and human level that continue to support the traditional, historical and empirical data that shows some of the herbal formulas can be useful," Blumenthal says."
