Five Elements in Chinese Medicine
All internal organs are organized in Yin and Yang partnership. The solid organs, i.e. the Liver, the Heart, the Spleen, the Lung and the Kidney (some also count the pancreas) produce, transform, regulate and contain Qi and blood. They have solid structure and rather passive function therefore belong to Yin, as Yin represents the matter and structure.
The hollow organs, i.e. the Gall Bladder, the Small Intestine, the Large Intestine, the Urinary Bladder, the Stomach and the Triple Burner are responsible for the digestion, and the transportation of nutrients and waist. They have a hollow structure and an active function therefore belong to Yang, as Yang represents the function, the force, the warming principle in Chinese medicine.
Each of the Yin - Yang organ partnership corresponds to a certain element. The Liver and its partner organ the Gall Bladder correspond to the element Wood; the Heart and its partner organ the Small Intestine correspond to the element Fire; the Spleen and its partner organ the Stomach correspond to the element Earth; the Lung and its partner organ the Large Intestine correspond to Metal; the Kidney and its partner organ the Urinary Bladder correspond to Water.
The Five Elements are in a relationship with one another. For example Wood generates Fire, thus the Liver (Wood element) and the Heart (Fire element) are in "generating relationship", in which the vitality of the Liver maintains and supports the Heart and its functions. On the other hand Water extinguishes Fire, thus the Kidney (Water element) and the Heart (Fire element) are in "controlling relationship", in which the Kidney "controls" and restricts the Heart, etc.
It is common to assign pathology to an organ with the most typical symptom manifestation for that pathology, but in fact, the origin of the pathology might be in a completely different organ. This could be grasped through the generating and restricting relationships between the organ-elements. The pathological organ often “hides” behind the symptoms of an organ it is in a relationship with. For example chronic cough with phlegm is typical Lung symptom and conventional medicine would therefore treat the Lungs. The origin of the pathology, though, most likely hides in the Spleen/Stomach partnership. The Earth element (Spleen/Stomach) may be disbalanced because of bad eating habits, and may transfer this disbalance to the Metal element (Lung), with which it is in a generating relationship. While there would be some symptoms that may lead to the Spleen/Stomach pathology the main symptoms will still come from the Lung, making finding the root of the disease difficult. Thus the treatment may become merely symptomatic and the cause of the disease may worsen, as it has remained untreated.
If applied correctly the Five Elements theory may help to find the root of the disease, and treat the disease before it has damaged organ tissues and structures.
Here are the Five Elements relationships in a drawing for better comprehension.
Besides the Yin and Yang, and the Five Elements theories, there are also other concepts and principles in traditional Chinese medicine diagnosis, such as the Four Levels, the Six Stages, the Seven Emotions, the Eight Principles, etc. These will not be reviewed in this Project in order to keep things simple and help the general public grasp the basic Chinese medicine principles without confusion. An essential part of introduction to Chinese medicine, though, is the concept of Qi, which is reviewed in the Vitality chapter.
