The Fei –Shen
relationship is mainly reflected in Qi movement, water metabolism, and the mutual supplementation of Yin-fluid.
Fei regulates water circulation, and Shen
regulates water metabolism. Fei
regulates respiration, and Shen
regulates the reception of air energy. Shen
and Fei
can contribute to the condition of “the Shen
failing to accept the fresh Qi”
, which manifests as breathlessness, cough, or asthma. Fei
and Shen
cooperate to metabolize water.
Clinically, deficient Fei -Yin and deficient Shen
-Yin often occur simultaneously, with symptoms that include a dry throat at night, a dry cough, night sweats, a feverish sensation of the palms and soles, and so on.
