From Essential Prescriptions of the Golden Cabinet (金匮要略 jīn guì yào lüè, huáng dǎn mài zhèng bìng zhì). Jaundice characterized by a blackish facial complexion. Black jaundice arises in persistent jaundice as a result of liver-kidney debilitation and stasis turbidity causing internal obstruction. The body is yellow and lusterless, while the eyes and face are blackish. There is anguish in the heart, dry skin that is insensitive to scratching, black stool, bladder tension (smaller abdominal distension and fullness), heat in the underside of the feet, and a weak floating pulse. In severe cases, the abdomen is distended as if containing water, the face is puffy, and pain in the spine prevents the patient from standing erect.
Medicinal therapy: Treat by supporting right and supplementing the liver and kidney, supported by attacking evil and transforming stasis. Niter and Alum Powder (硝石矾石散xiāo shí fán shí sǎn) can be combined with liver-kidney–enriching medicinals.
