About
癀 is a phono-semantic compound used in medical and veterinary terminology to denote jaundice or a severe epidemic disease, particularly in draft animals like cattle and horses. Its structure features the semantic radical 疒, meaning sickness, which establishes its pathological category. Enclosed within this radical is the phonetic component 黃 (huáng, yellow), which provides the pronunciation and reinforces the semantic clue of yellowing skin and eyes typical of jaundice. The character functions as a specific diagnostic label in historical texts, focused entirely on physical pathology.
