Principle of qi as the absolute energy of all phenomena in TCM

Qi: The Supreme Energy
Chinese medicine is founded on the principle of qi as the absolute energy of all phenomena. The characteristics of qi are ephemerality, activity, constant change, and warmth. It forms the basis for all organic life, meaning people, animals, and plants, as well as for all inorganic substances, such as minerals. In life, qi is expressed both specifically and generally. Generally, one who is youthful and energetic exudes abundant qi, but qi wanes with age, exposing one to accompanying infirmities, weaknesses, and degenerative symptoms. It is in this area of health maintenance and longevity that Chinese herbalism, with its highly evolved concept of tonics, can prove a very positive asset. Specifically, qi is expressed in the strength of the individual organs, including respiration, nerve force, reproductive power, and digestion. The qi of plants is perceived in their growth, odor, flavor, texture, and color. Minerals have a slower qi that undergoes transformation and change almost imperceptibly over great periods of time.

From the Chinese perspective, the fundamental principle of health and healing is dependent on qi flow and removing its blockage. This is accomplished with all of the Chinese healing modalities, including the science of herbalism and dietetics (which use the various textures and flavors to stimulate organic processes), acupuncture, Chinese massage (tui’na) and exercise, such as qi gong and tai chi. In contrast, Western herbalism and dietetics are primarily based on micronutrients and biochemical constituents. Chinese herbalism and dietetics more obviously use both energetic responses, classifying herbs and foods "organolepti-cally," according to their flavors, energies, textures, and colors. Today, these are considered along with the various quantifiable components, such as protein, carbohydrate, fats, vitamins, and minerals, according to individual indications. The immune system is also seen as a form of qi that it can be negatively influenced by pollution, bad diet, physical and emotional stress, and other factors. This eventually becomes the underlying cause for disease.
