Pathology of Yin and Yang


Yang Deficiency

In Yang Deficiency, the functions of Yin dominate. Yang is too weak, to fulfill its function and to restrain Yin. The resulting symptoms are either expression of the relative excess of Yin or of the weakness of Yang. Which symptoms appear, depends on the involved organs.
Because Qi is a part of Yang, Yang Deficiency contains always signs of Qi Deficiency. The essential difference lies in the Cold-signs that are evident in Yang Deficiency.

Pathogenesis of selected symptoms

Cold-sensations, cold extremities:
Cold signs develop, because the warming function can no longer sufficiently be fulfilled.

Copious, watery secretions (sputum, urine):
If Yang's holding function is weakened, excessive secretions are resulting (frequent urination). Further more is the Yang's function of transforming restricted, so that cloudy fluids manifests, which cannot be used by the body and these waste products are likely to be stored inappropriately.

Soft stools:
If Yang is deficient, Yin will moisten the body excessively.

No thirst, desire for warm drinks:
This is an expression of Yang Deficiency Cold.

Pale facial complexion:
An expression of insufficient Qi- and Blood-circulation.

Fatigue:
A sign of absent Yang activity.

The symptoms of Yang Deficiency appear, if a relative Yang Deficiency exists. Clinically it is important to determine which of the patients organs is affected by the deficiency. This question can be answered if one's differentiation is based on the organ specific symptoms.
Kidney, Lungs, Heart and Spleen are the organs in which Yang Deficiency is most likely to occur.
