《黄帝内经·灵枢·终始》
寸口脉大于人迎脉一倍的，是病在足厥阴肝经，治之当泻足厥阴肝经，而肝与胆相表里，肝实则胆虚，故当同补足少阳胆经。
所以日二取之者，太阳主胃，大富于谷气，故可日二取之也。
A Cunkou pulse greater than the Renying pulse by a factor of one indicates that the disease exists in the Liver Meridian of Foot Jueyin. The treatment should involve purging the Liver Meridian of Foot Jueyin. The liver and gallbladder are interlinked and interdependent. When the liver is full, the gallbladder is deficient. Thus, the Gallbladder Meridian of Foot Shaoyang should also be tonified.
