Chronoacupuncture

Chronoacupuncture involves stimulating specific key acupoints based on the theory of “Heavenly Stems and Earthly Branches” . It is a classic mode of acupuncture that can achieve human body harmonization by choosing specific acupoints by a precisely calculated period of time rather than syndrome differentiation. There are two types of Chronoacupuncture in clinical practice, one is Twelve Channels Chronoacupuncture also called ziwuliuzhu (子午流注) and the other is Eight Extra Channels Chronoacupuncture also called Ling Gui Ba Fa (靈龜八法) and both of which are calculating effective acupoints at particular moment so as to regulate twelve channels system and eight extra channels system respectively.
