What is a symptom associated with LU Dryness?

The symptom associated with LU (Lung) Dryness is indeed characterized by night sweats and a red tongue with no coat. In Traditional Chinese Medicine, Lung Dryness is often indicated by symptoms that suggest a deficiency of body fluids, leading to dryness in the lung tissue.

Night sweats highlight the body's struggle to maintain moisture, which is often associated with yin deficiency conditions, frequently linked to lung dryness. A red tongue with no coating indicates heat and dryness in the body, reflecting a lack of nourishing fluids. This combination of symptoms is typical for conditions involving lung dryness or yin deficiency affecting the lungs, illustrating the struggle of the lung system in maintaining hydration and balance.

The other choices present symptoms that do not align with the characteristic patterns of Lung Dryness. For instance, a wet cough and phlegm indicate excess conditions, not dryness. A heavy chest and dizziness are often related to phlegm accumulation or Qi stagnation, while a sore throat with thick mucus suggests the presence of phlegm and heat, further deviating from the dryness pattern.
