Wind in nature is the primary exogonous pathogenic factor in causing disease...Wind in nature blows in gusts and is characterized by rapid changes.Disorders caused by pathogenic wind,therefore,are marked by migratory symptoms,rapid changes,and abrupt onset of disease...Moving pathogenic wind in the body can cause dizziness,vertigo,fermitus,convulsions,and opisthotonos.Examples are tetanus and deviation of the mouth and eyes with spasm of the facial muscles. Observation of the eyes: The liver opens into the eye and the essential qi of the five yin and six yang organs all goes up into the eyes...Upward, straight forward or sideways staring of the eye is mostly caused by disturbance of liver wind.
