Kidney yin deficiency syndrome (KYDS) (KYDS)

Kidney yin deficiency syndrome (KYDS) is a fundamental pathological pattern in Traditional Chinese Medicine (TCM) characterized by the depletion of "Yin" essence, leading to a loss of moistening and cooling functions within the body (WHO International Standard Terminologies, 2007). It is clinically identified by symptoms such as night sweats, malar flush, dizziness, and a rapid, thin pulse (PMID: 31211314). Modern biomedical research suggests that KYDS is not a single molecular entity but a systemic state of dysregulation involving the neuroendocrine-immune (NEI) network and the hypothalamic-pituitary-adrenal (HPA) axis (PMID: 28655536). Therapeutic interventions, such as the herbal formula Liuwei Dihuang Wan, target this syndrome to restore homeostatic balance by modulating cortisol levels and inflammatory cytokines (PMID: 25635150). Consequently, KYDS serves as a diagnostic framework for treating various chronic conditions, including diabetes, hypertension, and menopausal symptoms, where it correlates with specific metabolic and hormonal imbalances (PMID: 30104553). Addressing this syndrome involves a multi-target approach that influences oxidative stress and metabolic regulation rather than a single receptor interaction.

Herbal interventions for this syndrome typically function by nourishing the Yin essence, clearing deficiency-derived heat, and modulating the hypothalamic-pituitary-adrenal (HPA) axis to restore systemic homeostasis (PMID: 28655536).
