Kidney Yang

"Kidney Yang" is a Traditional Chinese Medicine (TCM) concept described as the "warming and motivating" force fundamental to the body's energy, metabolism, growth, and reproduction. It represents the active, functional power derived from the kidney organ system (in the TCM sense) and is seen as the root of vital fire (true yang, primordial yang, or minister fire), driving physiological activities throughout the body. Loss or deficiency of Kidney Yang manifests as fatigue, coldness, and metabolic decline according to TCM and is addressed by herbal formulas and lifestyle practices meant to "tonify" or "invigorate" Yang. There is no recognized molecular entity or receptor corresponding to "Kidney Yang" in modern biomedical science. In summary: **Kidney Yang** is a TCM physiological concept, *not* a drug target, receptor, protein, or gene, and does not fit the requirements for molecular target annotation.
