Which of the following is NOT a sign of Yin deficiency?

Yin deficiency in Traditional Chinese Medicine (TCM) generally manifests through symptoms that indicate a lack of cooling and moistening resources in the body. Signs of Yin deficiency often include dryness, heat sensations, and an increase in metabolic activity, which can lead to various discomforts.

Dry throat is a characteristic sign of Yin deficiency, reflecting insufficient fluids and nourishment in the body. Night sweats are also commonly associated with this condition, as the internal heat generated by the deficient Yin can lead to sweating, particularly during sleep. Frequent urination can be a sign of Yin deficiency as well, as it may indicate an imbalance where the body is unable to retain fluids properly.

In contrast, clear and copious urine is typically not associated with Yin deficiency. Instead, it is more indicative of a condition where there is excess Yang or an accumulation of fluids that are not being transformed properly. This symptom might suggest a different underlying pathology, such as a Yang deficiency or issues related to the spleen or kidneys. Thus, clear and copious urine stands apart as not being a sign of Yin deficiency.
