[Deqi(qi arrival) theory in ancient TCM books]

Acupuncturists in all ages emphasize deqi(qi arrival). We arranged and analyzed contents on deqi and qi arrival electronic texts in 1156 ancient medical books through Chinese Medical Code, the major electronic series of books on TCM, with medical classics as well as acupuncture-moxibustion and tuina parts as the emphasis. It is found that deqi is a standard for traditional acupuncture effect evaluation. Meanwhile, it acts on regulating body cold, heat, insufficiency and excess, guiding reinforce-reducing manipulation, determining needle depth, retaining and withdrawing, as well as prognosis, etc. Deqi takes the priority in clinical and scientific research.
