Methodology Analysis based on:  Encompassed from Science Citation Index (SCI)  Published between 1991 to 2002  Included keyword ‘herbal medicine’ Analysis parameter:  Yearly production (P) and publication distribution (P%)  Citation per Publication (CPP): total citation/total publication  Relative citation rata (RCR): CPP/total CPP  Country of origin of authors and corresponding authors  Language Reference 1.Choi DW, Kim JH, Cho SY, Kim DH, Chang SY (2002), Regulation and quality control of herbal drugs in Korea.
