[Origin and application: "body schema" of acupuncture and moxibustion from the perspective of astrology and numerical arts].

The "body schema" of acupuncture and moxibustion is centered on the meridian system and represents a corporeal perspective of "heaven-connection", embodying the harmony between nature and humanity. It integrates the cyclic schema of the heavenly cycling, the meridian growth and decline schema of the <i>guaqi</i> theory, the twelve zodiac demarcation schema from astrological and astronomical studies, and the nine-palace and eight-trigrams schema of temporal and spatial locations. It presents the theoretical origins of the harmony between nature and humanity in acupuncture and moxibustion along with medical thoughts under the background of social concepts. The numerical arts of acupoint number and acupuncture-moxibustion quantity, those of acupuncture-moxibustion time and taboos, as well as the time-based acupuncture-moxibustion patterns, all of these thoroughly reflect the application of the body schema of acupuncture and moxibustion by early medical practitioners in ancient time. The study on the body philosophy in acupuncture and moxibustion should start from the original appearance of early classical acupuncture-moxibustion theory, trace the source of body philosophy of acupuncture and moxibustion, seek the truth of temporal body medicine, and perfect the body philosophy research of contemporary acupuncture and moxibustion, so as to improve the dual attributes of acupuncture and moxibustion in humanities and science.
