About
疸 is a phono-semantic compound where the radical 疒 (sickness) forms a partial enclosure around the phonetic component 旦, which provides the pronunciation "dàn" (often pronounced "dǎn" in context). The character specifically means jaundice, a medical condition causing yellowing of the skin and eyes due to excess bilirubin. It most commonly appears in the compound 黄疸, meaning "jaundice". The sickness radical places it firmly within the medical domain, denoting a pathological bodily state.
