This presentation offers an explanation of this enigmatic area of acupuncture. Its clinical uses and mastership offer the potential to rebalance the Zang-Fu organs directly and impact many complex chronic problems. Dr Butch Levy M.D has evolved from his initial medical training in primary care to a wholistic clinical practitioner. His current practice integrates this diverse background, bridging the East and West. He has also written and taught more extensively; teaching seminars on the Eight Extraordinary Vessels, The Art of Kampo and Integrative Oncology. This Lecture is part of the ICCM Meet project
