Lung meridian (Taiyin Lung meridian) (LU (used as point abbreviation in acupuncture charts))

“Lung yin nourishment pathway” refers to a principle in Traditional Chinese Medicine describing the circulation of vital energy (Qi) along the Lung meridian, where the balance and sufficiency of ‘Lung yin’ (moistening and cooling functional energy) is necessary for healthy breathing, moisture regulation, and immune defense. The Lung meridian runs from the chest internally down the arm, ending at the thumb, and is treated via acupuncture points to address respiratory symptoms, fluid regulation issues, or emotional imbalances. This is a channel-based concept without a direct molecular correlate, and is not considered a receptor, enzyme, or molecular target in Western medicine. The phrase does not map to any known molecular structure, pharmacological target, or scientific abbreviation in biomedical science.
