Three sets of Korea′s oldest medical book series titled ″Donguibogam″... have officially
become national treasures on Monday.
The Cultural Heritage Administration said the series， which literally means ″Mirror
of Eastern Medicine，″ was first compiled by a royal physician named Heo Jun... during
the Joseon Dynasty.
The three sets， that were promoted as national treasures， were part of the encyclopedia′s
first prints from the 17th century.
The entire 25－volume series of ″Donguibogam″... was listed on UNESCO′s Memory of the World
Register in 2009.
