Clinical commentary 臨床

Dongyuan's thermal rule made into its purest instrument — the hot meal gets the two yellows, with bupleurum and cimicifuga lifting the lid the heat has pressed down. Mung-bean sized, like all the chapter's coolers: small pills for hot problems. — Eui Young (Justin) Chung, L.Ac., Dipl. O.M.
