Traditional Chinese medicine and Western medicine have very different perception on what an emotion is, where it originates from, and how to approach it if it becomes extreme.
Western medicine places the command of all physical and psychological behavior in the brain. The limbic system, a network of brain structures and pathways, is considered to be in charge of emotional behavior. The amygdala - one of the limbic system structures - plays role in experiencing intense positive or negative emotions such as anger, fear, or joy. Another structure - the hypothalamus – serves as a mediator between the brain and the body, and helps control metabolism, sleep, hunger, thirst, body temperature, and sexual behavior. It is the brain’s most direct link to the body glands that are active in emotions. The endocrine glands themselves influence behavior by secreting hormones into the bloodstream, bringing about a variety of physiological and psychological changes(1).
In traditional Chinese medicine the behaviour is not manifested by a single structure (the brain) but by the interaction of the internal organs' emotional aspects.
From TCM perspective an organ can be viewed to manifest biologically (the Yin and Yang aspect - the organ’s anatomy and physiology), vitally (the Qi aspect), and mentally/emotionally (the way the organ affects the emotionality of the person through the emotion associated with the organ). These different aspects are not independent from one another but are co-dependent and interrelated. If one aspect becomes imbalanced the others will also get affected. For example if the biochemistry of the Liver is impaired from alcohol abuse the Qi of the Liver will be stagnated (on a vital level), and anger will manifest (on emotional level) thus the vital and the mental/emotional aspects of the Liver will also be imbalanced. Vice versa – extreme long-term anger (the emotion of the Liver) can generate heat in the Liver, which will eventually consume the Yin of the Liver (substance/matter) thus affect the Liver’s biochemistry. So if a single aspect becomes chronically imbalanced the other attributes will eventually become imbalanced as well.
“Thus, in Chinese Medicine, body, mind and emotions are integrated whole with no beginning or end, in which the Internal Organs are the major sphere of influence.” (pg.129) (2)
