The Tucson Acupuncture and Chinese Herbs logo is a Chinese character for Ben Shen, meaning "rooted in Spirit." The concept that all of acupuncture's laws first must be rooted in spirit is based on the ancient document of the Yellow Emperor's classic text, Chapter 8, Ling Shu (Spiritual Pivot) circa 2600 B.C. This is the foundation of acupuncture at Tucson Acupuncture and Chinese Herbs.
