Phlegm (traditional Chinese medicine theory)

Phlegm in traditional Chinese medicine is a core pathological factor arising from impaired fluid metabolism, typically linked to Spleen dysfunction and accumulation of dampness. Phlegm encompasses both visible forms (e.g., expectorated mucus) and invisible forms that may present as lumps, nodules, mental disorders, or circulatory disturbances. While "phlegm" in biomedicine refers to airway secretions, TCM phlegm includes diverse bodily manifestations not directly mapped to a molecular entity. Treatment focuses on correcting imbalances through herbs, acupuncture, diet, and lifestyle. Phlegm is not a therapeutic or druggable target in biomedical terms but remains a key diagnostic and treatment consideration in TCM. In summary: Phlegm (TCM) is a conceptual, not molecular, entity; it cannot be classified as a receptor, enzyme, transporter, or other conventional therapeutic target. It is best understood as a symbolic or syndromic description unique to the diagnostic framework of TCM.
