Yin and Yang Functions

  • Yin is the material basis for Yang
  • Yang is the functional manifestation of Yin
  • An excess of yang implies a deficiency of Yin and vice versa. This is the general characteristic of acute conditions
  • In chronic conditions, a deficiency of one aspect does not always cause an excess of the opposite
  • In extreme chronic conditions there is usually a deficiency of both Yin and Yang. It is almost  impossible to see a case of an excess simultaneously of both Yin and Yang. In case of deficiency of both Yin and Yang, tonifying either aspect will benefit the opposite aspect.

The Functions of Yin

It Cools: By virtue of its fluidity the Yin cools the body, therefore an even temperature is maintained when the Yin and Yang is in harmony

Nourishes: This aspect of Yin, in the form of Ying Qi, supplies the nourishment to the meridians (the body fluids and blood nourish at all levels.)

Provides rest (inactivity): When this nature is in balance with the Yang, it enables us to use our energy better, recover easily from fatigue and preserve a good quality of life for a long time. When this nature is not in harmony, hyperactivity will exist and stagnation can develop.

The Functions of Yang

Warms: Warms the body

Transforms (Change): All transformation of energy relies on Yang. This is usually provided by its nature to warm.

Protects: It’s nature is to defend the body against external pathogens. This is provided in the form of Wei Qi (Defensive or Guardian Qi.)

Moves: Body Fluids and Blood are dependent on th movement of Yang Qi.

Holds: Even though the nature of Yang is to move, Yang also has the the nature to hold Blood, Body Fluids, and Organs in their proper place.
