Clinical commentary 臨床

Qian Yi's again, and the tradition's standing formula for a hot cough — two barks that cool the lung, and licorice. White is the lung's colour, and 瀉白 drains it as 瀉靑 drained the liver and 瀉黃 the spleen. Still prescribed for bronchitis, often with the six additions. — Eui Young (Justin) Chung, L.Ac., Dipl. O.M.
