Xin regulates both Blood circulation and its volume, while Gan
stores Blood like a reservoir. The two viscera, therefore, coordinate Blood circulation. Xin
regulates the activities of the Spirit. Gan
regulates dredging and dispersing, which adjust emotional activities to maintain a balance of health. The two viscera, therefore, also coordinate mental and emotional activities.
Deficient Xin -Blood and Gan
-Blood often affect each other, leading to a pale complexion, palpitations, insomnia, blurred vision, and so on. The conscious mental activities of a person are controlled by Xin
and benefit from the smoothing function of Gan
. Xin
and Gan
often affect each other, as in the flaring-up of Fire of both viscera.
