In the《Jingui Yaolue》tradition, this formula is described for a yellowing pattern arising from sexual taxation (女勞): late-afternoon fever yet aversion to cold, a black forehead, hot soles, the whole body yellow with black stools — a "black 疸" (黑疸); the classics note that abdominal fullness made it hard to resolve.
