Traditional Chinese medicine analyzes pathological factors on the basis
of clinical manifestation of symptoms and signs. These disease-causing
factors can be triggered by external influences such as variation of
weather, irregular food intake, stress, lack of physical activity, and
traumatic injuries. Internal (or emotional) factors can also cause
disease. There are seven main emotions: joy or excitement, anger,
sadness, worry, grief, fear and fright. Therefore, no two illnesses are
ever the same because each person's internal and external influences
interacting together create a disorder specific to the individual. This
is a very different view from the practice of Western medicine. In
most cases, Western medicine treats the body, mind and external factors
separately and does not necessarily view them as interdependent parts.
For example, an Ophthalmologist treats only an eye problem. A Chinese
doctor will look at an eye problem and ask "how is your liver?"
