What is Qi? Qi in TCM Acupuncture Theory - TCM Theory
Qi, pronounced "chee", means energy. You may see it spelled "Chi" or even "Ki" in Japanese, but they all carry the same meaning. Qi is the energy of the body, of the meridians, of food, of the universe. While it may seem a nebulous topic there are refined theories regarding the different types of Qi within the body, the creation and actions of Qi and, consequently, ways to determine where imbalances may arise.

Basic Types of Qi
Within the body there are two basic types of Qi. Congenital Qi is the Qi that we are born with. It is essentially limited and the quality and amount of this Qi represents our basic constitution. Acquired Qi, on the other hand, is derived from the foods we eat and the air that we breath. The quality of acquired Qi depends on our lifestyle habits such as food quality, balance of emotions, physical exercise and so on. The details regarding these two basic types of Qi are below:
- Congenital Qi
- Acquired Qi
Map of the Creation of Qi
The graphic below describes the processes which take place within the body to produce the various types of Qi. If you click on a particular box it will take you to the next section where each type of Qi is described in full detail.
Detailed Types of Qi
While we use the word Qi to mean energy, it is clear from the Chinese medical theories that there are many aspects and differentations of Qi. Different types of Qi vary in how they are used by the body and what imbalances are caused by a deficiency. For example, Jing deficiency in children may present with signs of slow growth and poor mental development, whereas, a person with a deficiency of Wei Qi may experience frequent colds and/or infections.
The various types of Qi and their corresponding sources, functions, distributions and relevance are described below:
- Jing (Essence)
- Derived from parents, supplemented by Acquired Qi (Gu Qi & Wei Qi).
- Responsible for growth, reproduction and development.
- Stored mainly in the Kidneys.
- Weak Jing in children may lead to poor bone development, slow learning a/or poor concentration.
- Weak Jing in the elderly may lead to deafness, osteoporosis a/or unclear thinking.
- Yuan Qi (Original Qi)
- Derived from Jing.
- Promotes and stimulates functional activities of organs.
- Provides the foundation/catalyst for the production of Zhen Qi.

Deficiencies in Yuan Qi may lead to poor development of Acquired Qi.
- Gu Qi (Essence of Food and Grain Qi)
- Originates from the action of the Spleen on the food in the Stomach.
- Combines with Kong Qi to form Zong Qi.

Functions of Qi in the Body
Generally speaking, the Qi serves several vital functions within the body. When imbalances arise, they are seen as disruptions in the functions of Qi. A prolapse, for example, is seen as a disruption in the ability of Qi to provide the raising and stabilizing function on a particular organ. In this case certain acupuncture points which have a strong lifting and stabilizing effect such as GV 20 may be used to help rebalance the body.
The main functions of Qi within the body are listed below:
- Catalyzing Functions: Qi assists in the formation and transformations within the body, for example the transformation of food into Qi and Blood
- Protecting Functions: Qi defends the body from external pathogens
- Raising and Stability Functions: Qi holds organs in their place, keeps Blood in the vessels, governs the removal of fluids
- Transporting Functions: Qi is the foundation of all movement and growth in the body.
- Warming Functions: Qi helps to control homeostasis and provides warmth for the body.
Qi Disharmonies with Signs and Symptoms
Qi has four main states of imbalance. These imbalances may effect many parts of the body at once or within a particular meridian, organ or area. Deficiency of Qi, for example, may effect the Lungs with symptoms of shortness of breath, the Stomach/Spleen with symptoms such as poor appetite and the body in general with symptoms of fatigue and weakness.
