In Oriental Medicine, health is the ability of a person to respond appropriately to a wide variety of challenges. Disease represents a failure to adapt to these challenges, be they weather changes, emotional stress, migraines, or other daily stressors. Your mind and body are a system in a continuous process of transformation. Your thoughts and emotions are as much a part of this process as are your tissues and blood in producing Qi (chee), life's animating force and substance.
