Yin Deficiency with Internal Heat

Insufficient yin fails to restrain yang, producing a pattern of deficient heat rather than excess heat.

Afternoon tidal fever, night sweating, dry throat, five-center heat, red tongue with scant coat, thin rapid pulse.

Afternoon tidal fever, night sweating, dry throat, five-center heat, red tongue with scant coat, thin rapid pulse.

Unlike excess heat, this pattern is usually chronic, weaker in intensity, and lacks forceful signs such as a thick yellow coat or marked constipation.

Heat signs do not automatically equal excess fire. If the heat is worse in the afternoon or at night and the tongue coat is scanty, think deficient heat first.
