Aphrodisiacs help Nigerian men keep multiple wives happy

KANO, Nigeria: Men trying to keep several wives happy and women competing with co-wives for their husbands' attentions have led to a boom in the sale of aphrodisiacs in predominantly Muslim northern Nigeria.

"Demand for sex stimulants has been unprecedented in the last four years," herbalist Sule Adamu said in his dingy office on the outskirts of Kano.

Adamu, who has 40 years in the business, reckons his clients, mostly men, have more than tripled in number since 2005.
