What symptom is commonly associated with "Yin deficiency"?

Yin deficiency is characterized by an insufficient amount of the body's cooling and nourishing energies, leading to a state often associated with heat sensations. This condition can manifest as various symptoms, such as night sweats, dry mouth, increased thirst, and a feeling of warmth in the body, which reflect the imbalance and the lack of Yin that would normally help to keep Yang (the heat) in check. The presence of heat sensations indicates that the body is experiencing a deficiency in the cooling aspects of Yin, leading to an over-expenditure of Yang energy, resulting in an overall sense of heat within the body.

This understanding of Yin deficiency allows practitioners to diagnose and tailor treatments that restore the balance between Yin and Yang, addressing the root cause of the discomfort.
