The Model of Integration of Traditional Medicine with Modern Medicine in Hospitals of Traditional Medicine in Vietnam:Present Status and Prospective Plan

引用

Chinese Journal of Integrative Medicine 2008年第3期14卷 228-231页

作者： CHU Quoc truong National Hospital of Traditional Medicine HanoiVietnam

Vietnam has a 4000-year old traditional system of pharmaco-medicine which was founded during the Hung King era （2879-257 B.C.）. Vietnamese traditional medicine （TM） came from the society and was developed during the long years of living, working and struggling for existence among the Vietnamese people among 54 ethnic groups under extremely severe natural conditions, conflicts, and interaction with local neighboring nations such as China, Laos, Cambodia, india, etc. All of those form the foundations to shape the diversity, abundance and specialty of Vietnamese TM. Valuable experiences in TM have been transmitted from generation to generation, which is an important part of Vietnamese culture.
