This way of diagnosis is made by reviewing and summarizing a disease, and then identifying an organ disharmony as final conclusion. Differentiation of organ disharmony is based on the functional and pathological manifestations of organs, as well as the interrelationships between the organs. Since organ disharmonies involve in a variety of diseases, differentiation of organ disharmony becomes the basic for clinical diagnosis, and usually used together with other diagnostic methods.
In western medicine, the body’s organs are explained in terms of their anatomical structure and physiological functions. However, in Traditional Chinese Medicine (TCM), the approach is quite different. Organs are considered functional units of the body. Therefore, what is typically thought of as an organ has a much broader meaning and application in TCM. An organ’s anatomical structure is not as important as its yin yang properties or relationships with other organs. Chinese medicine recognizes five yin organs (heart, liver, spleen, lung & kidney) and six yang organs (gall bladder, stomach, small intestine, large intestine, bladder and triple burner), also known as “zang” and “fu” organs respectively. See article on “Understanding the Body’s Organ from a TCM Perspective.”

Zang-organs & fu-organs in TCM
Disorders in organs may be due to organs themselves, or it may result by a broken relationship between the organs. Therefore, the health of the organs is identified according to their unique physiological functions. Problems arising in the five “yin” or “zang” organs tend to be more serious. Below are a brief description of the main syndromes attributed to each of the organs.
Disharmonies of heart and small intestine
Disharmonies of liver and gall bladder
Disharmonies of spleen and stomach
Disharmonies of lung and large intestine
Disharmonies of kidney and bladder
