Dryness
Dryness is the main pathogenic factor in autumn. Its characteristics
are as follows:
Pathogenic dryness is apt to consume yin, especially body fluids
Clinical manifestations are dryness of the mouth, lips and nose, dryness of the tongue, dry, rough and chapped skin, dry stool, etc.
Pathogenic dryness is liable to injure the lung
The lung is considered a tender organ which prefers moisture, cleanliness, and descent. If pathogenic dryness attacks the body from the mouth and nose, the yin fluid of the lung is likely to be consumed. It may lead to the dysfunction of dispersion and descent, and manifest as dry cough with scanty sputum, sticky mucus causing difficult expectoration, or bloody sputum, etc.
Commonly seen syndromes caused by pathogenic dryness are cool dryness and warm dryness.
Main clinical manifestations of cool dryness: fever, aversion to cold, headache, no sweating, dryness of the mouth and nose, dry skin, cough with scanty or no sputum, dry white and thin tongue coating.
The symptoms of cool dryness are similar to symptoms caused by exogenous pathogenic cold, but are accompanied with the symptoms of body fluid insufficiency.
Main clinical manifestations of warm dryness: fever, mild aversion to wind and cold, headache, scanty perspiration, dry cough, or cough with a small amount of sticky sputum, dry skin, thirst, irritability, red tongue tip and sides, and dry scanty tongue coating. The warm dryness syndrome is similar to the mild heat syndrome, indicating that the body fluid is exhausted.
