Clinical commentary 臨床

A single drug and cold water. Rhubarb powdered fine and made into a paste is one of the few one-ingredient applications in the chapter, and the claim is modest and specific: 痛止, the pain stops. It is a claim that may well be true, and not for the reason the source gives. A cool wet paste on an inflamed, broken skin surface relieves pain by itself, and rhubarb's anthraquinones and tannins are mildly astringent and antibacterial. The same formula appears again in this chapter among the burn remedies, where the mechanism is the same. 凍瘡 at 2.14 covers both chilblains and true frostbite, which need opposite handling. For a chilblain whose skin has broken, this is a reasonable dressing. For a frozen extremity it is beside the point: rewarm in water at 37 to 39 degrees, do not rub, do not apply dry heat, and leave the question of what tissue is dead for the weeks it takes the line to declare itself. — Eui Young (Justin) Chung, L.Ac., Dipl.
