問曰：脉有陰陽者，何謂也？答曰：凡脉大、浮、數、動、滑，此名陽也；脉沉、濇、弱、弦、微，此名陰也。凡陰病見陽脉者生，陽病見陰脉者死。
问曰：脉有阴阳者，何谓也？答曰：凡脉大、浮、数、动、滑，此名阳也；脉沉、涩、弱、弦、微，此名阴也。凡阴病见阳脉者生，阳病见阴脉者死。

The Master asked: “The pulse has yin and yang — what does that mean?” The answer: “When the pulse is large, floating, rapid, moving or slippery, it is named yang; when it is deep, astringent, weak, wiry or faint, it is named yin. In yin disease, seeing a yang pulse, the patient lives; in yang disease, seeing a yin pulse, the patient dies.”

寸口脉浮而大，浮爲虚，大爲實，在尺爲關，在寸爲格，關則不得小便，格則吐逆。
寸口脉浮而大，浮为虚，大为实，在尺为关，在寸为格，关则不得小便，格则吐逆。

When the inch mouth pulse is floating and large: the floating is vacuity, the large is repletion. At the cubit it makes a closing, at the inch a barrier. Closing, no urine passes; barring, there is vomiting.
大之兩面最須留意：寸口「大爲實」，太陽誤汗後「大則爲虚」。同形而異義，以有無胃氣、曾否發汗别之。
問曰：證象陽旦，按法治之而增劇，厥逆，咽中乾，兩脛拘急而讝語。師曰：言夜半手足當温，兩脚當伸。後如師言，何以知此？答曰：寸口脉浮而大，浮則爲風，大則爲虚。風則生微熱，虚則兩脛攣。病證象桂枝，因加附子參其間，增桂令汗出，附子温經，亡陽故也。厥逆，咽中乾，煩燥，陽明内結，讝語煩亂，更飲甘草乾薑湯。夜半陽氣還，兩足當熱，脛尚微拘急，重與芍藥甘草湯，爾乃脛伸，以承氣湯微溏，則止其讝語，故知病可愈。
问曰：证象阳旦，按法治之而增剧，厥逆，咽中干，两胫拘急而谵语。师曰：言夜半手足当温，两脚当伸。后如师言，何以知此？答曰：寸口脉浮而大，浮则为风，大则为虚。风则生微热，虚则两胫挛。病证象桂枝，因加附子参其间，增桂令汗出，附子温经，亡阳故也。厥逆，咽中干，烦燥，阳明内结，谵语烦乱，更饮甘草干姜汤。夜半阳气还，两足当热，胫尚微拘急，重与芍药甘草汤，尔乃胫伸，以承气汤微溏，则止其谵语，故知病可愈。

Question: the signs resemble yangdan; treating by the rule only made it worse — cold limbs, a dry throat, cramped calves and delirious speech. The master said: by midnight the hands and feet will be warm and the legs will straighten. It turned out as he said. How could he know? Answer: the cunkou pulse is floating and large; floating means wind, large means emptiness. Wind engenders faint heat, emptiness cramps the calves. The signs resemble the Cinnamon Twig pattern, but aconite was added in between and cinnamon increased to make sweat come out; aconite warms the channels, so the yang was lost. Cold limbs, dry throat, restlessness, yangming binding within, delirious and confused speech: again drink Liquorice and Dried Ginger Decoction. At midnight the yang returns, both feet grow hot, the calves are still slightly cramped; give Peony and Liquorice Decoction again and the calves straighten; with the Qi-Settling Decoction a slight looseness stops the delirium. Thus one knows the illness can be cured.

服桂枝湯，大汗出，脉洪大者，與桂枝湯如前法。若形如瘧，日再發者，汗出必解，宜桂枝二麻黃一湯。

After Cinnamon Twig Decoction, with heavy sweating and a surging, large pulse, give Cinnamon Twig again as before. If the pattern is malaria-like with two attacks a day, sweat will surely resolve it: Cinnamon Twig Two and Ephedra One Decoction is fitting.

問曰：脉病欲知愈未愈者，何以别之？答曰：寸口、關上、尺中三處，大小、浮沉、遲數同等，雖有寒熱不解者，此脉陰陽爲和平，雖劇當愈。

Asked: “In pulse illness, how does one tell whether recovery has come?” The answer: “When at cunkou, the bar and the cubit the three positions are equal in large and small, floating and deep, slow and rapid, then even if cold and fever are not yet resolved, the yin and yang of the pulse are at peace, and however severe the illness, it will recover.”
