Transformation

Transformation: the first and most fundamental function of Qi

Of the five functions attributed to Qi in Traditional Chinese Medicine, transformation is the most fundamental. It is the force that converts raw materials — food, drink and air — into the subtle and usable vital energy required by the body. Without transformation there would be no Gu Qi, no Blood, no Zhen Qi and no Wei Qi. Everything begins with the transforming action of Qi.

What is transformation?

Transformation is the ability of Qi to change substances from a coarser into a more refined state. Qi is Yang in nature — active, warm and moving — and it is precisely this Yang quality that makes transformation possible. Food and fluids, which are relatively coarse and material substances, require the activating force of Qi to be converted into subtler forms that the body can absorb and use.

This principle runs throughout TCM physiology. The health of the body depends on the quality of its transformation processes, and these processes in turn depend on the strength of the Qi of each organ involved.

Transformation by each organ

Each organ has its own specific transformational task. The Stomach receives food and "rots and ripens" it — a traditional description of the digestive process in which food is broken down and prepared for further processing. The Spleen extracts the essence of this processed food and transforms it into Gu Qi — Food Qi, which forms the basis for the other forms of Qi.

The Lung combines Gu Qi with inhaled air to form Zong Qi, which subsequently contributes to the formation of Zhen Qi — the refined Qi that circulates through the meridians. The Heart participates in the transformation of food-derived Qi into Blood. The Kidney transforms the fluids it receives and separates them into usable and excretable fractions. The Bladder performs Qi transformation of fluids in the formation and excretion of urine.

When transformation becomes impaired

When the transforming action of Qi becomes weak, characteristic pathological patterns may arise within TCM theory. Weak Spleen-Qi transformation may lead to insufficient Gu Qi production, poor digestion, tiredness and accumulation of Dampness. Weak Lung-Qi transformation may contribute to insufficient Zhen Qi and Wei Qi and is traditionally associated with susceptibility to external illness and a weak voice. Weak Kidney-Qi transformation may result in disturbances of fluid metabolism, such as oedema, urinary problems or impaired distribution of fluids.

In clinical TCM practice, identifying impaired transformation is therefore an important step in understanding many complex patterns. Treatment is directed at strengthening the Qi of the organ involved so that its transformational function can be supported.
