Durban - Far from being used widely in ancient Oriental medicine potions, horns from South African rhinos are now increasingly used to promote business deals or to ease the throbbing hangovers of rich, middle-aged men in Vietnam.
This is the surprising conclusion of a Vietnamese-born researcher at the Potchefstroom campus of North-West University.
Dr Dao Truong, who conducted a survey of more than 600 wealthy Vietnamese men in Hanoi and Ho Chi Minh City, found that 47% of the respondents admitted to using rhino horn for a variety of reasons.
The survey focused specifically on Vietnamese men with an income of more than the equivalent of R14 000 a month.
Nearly 90% were married and 99% had studied at university.
