Donguibogam 東醫寶鑑

治太陽證入裏, 煩渴而小便不利. 澤瀉 二錢半, 赤茯苓ㆍ白朮ㆍ猪苓 各一錢半, 肉桂 五分. 右爲末, 每二錢, 白湯調下. 或剉作一貼, 水煎服. ○傷寒汗後亡津, 但渴欲飮水者, 邪在裏也. 然上焦虛燥, 或飮水不散而反吐出, 爲水逆證; 或飮水雖多而小便不利者, 皆裏熱未實, 不能消水故爾. 五苓散的藥也. 《入門》

Translation

Treats the taiyang pattern entering the interior, with vexing thirst and inhibited urination. Alisma, 2 don 5 fun; red poria, atractylodes and polyporus, 1 don 5 fun each; cinnamon bark, 5 fun. Powder, and take 2 don stirred into plain hot water; or cut up, make one packet and decoct in water. ○ Where the fluids have been lost after sweating in cold damage and there is only thirst with a wish to drink water, the evil is in the interior. But if the upper burner is empty and dry, or the water drunk does not disperse and is instead vomited back, this is the water counterflow pattern; or if much water is drunk and yet the urine remains inhibited, in all these cases the interior heat has not yet become repletion and so cannot consume the water. Five-Ingredient Poria Powder is the apt medicine. — Immun 入門 (Donguibogam · Han, upper)

Clinical commentary 臨床

Thirst and inhibited urination together are the signature, and the paradox they present is the whole point of the formula: the patient is thirsty because the water they have is in the wrong place, not because they lack it. Drinking more makes the vomiting worse, which is the water counterflow the commentary describes. Four draining drugs plus five fun of cinnamon bark — a tenth of the formula, and indispensable, because the water will not move until something warms the qi that is supposed to move it. — Eui Young (Justin) Chung, L.Ac., Dipl. O.M.
