METHODS: Electronic database searches were con- ducted in the Chinese National Knowledge Infra- structure and VlP, and the Western databases, Pubmed, the National Science and Technology Li- brary, and the German Journal of Acupuncture, from 1990 to April, 2012. We also searched the doc- uments of international symposiums for auricular acupuncture points (AAPs). Keywords were "auricu- lar points", "auricular acupuncture points", "ear points", or "auriculotherapy" RESULTS: Basic and clinical research on AAPs was performed in China, the United States, France, andGermany. Clinical AAP research was done in Italy, Austria, Switzerland, Spain, the UK, Holland, Japan, Russia, and Africa. However, AAP research was not communicated internationally. The World Federa- tion of Acupuncture-Moxibustion Societies recom- mended international standard of auricular acu- puncture points (ISAAPs). Standardized nomencla- ture and locations of AAPs would provide a solid basis to draft an international standard organiza- tion. CONCLUSION: Experts need to find common points from different countries or regions, provide evidence of different ideas, and list the proposal as a recommendation for an international standard.展开更多
