庞安时云。尺寸俱沉细者。太阴受病也。当四五日。发其经布胃中。络于嗌。故腹满而嗌干。宜大承气汤下之。（郭
河南云。此即仲景辩太阴之说也。当详证而后可下。）
琥按上条论。仲景于序例中不言汤药。庞氏以腹满嗌干。的系太阴热证。故云。宜大承气汤。郭氏云。未可遽下
者。以其脉沉细。恐胃中未结实。琥又按伤寒例云。太阴受病。脉尺寸俱沉细。少阴受病。脉尺寸俱沉。厥阴受病。脉
尺寸俱微缓。凡言脉处。大都系叔和补入。兼之传写时。不无所误。以理论之。三阴经居里。脉皆当沉。岂有太阴少阴
脉既见沉。而厥阴更居于里。其脉反不言沉之理。今校正尺寸俱微缓者。当是太阴受病。尺寸俱沉细者。当是厥阴受病。
细字。乃弦字传写之误。尺寸俱沉。是少阴受病。无烦议耳。凡三阴证。宜用承气汤者。于沉脉中。必数而有力。惟太
阴脉微带缓。此为辩证最妙之法。
又云。伤寒脉浮缓。手足自温者。系在太阴云云。以脾家实腐秽当去故也。橘皮汤主之。
橘皮（一两） 生姜（二两）
细锉。水一升半。煎七合。去滓。分二服。稍热呷。未瘥。再作服。
琥按上主疗云云。即仲景原论也。仲景云。腐秽当自去。故无方治。今庞氏用橘皮汤者。内安太阴。去秽恶。扶

Pang Anshi stated: When both the cun (distal) and chi (proximal) pulses are deep and fine, it indicates that the Taiyin meridian is affected. Typically, on the fourth or fifth day of illness, the pathogen spreads along the meridian into the stomach and connects with the throat; therefore, abdominal fullness and dryness of the throat occur. It is appropriate to use Dachengqi Tang (Major Order the Qi Decoction) to purge and drain heat. (Guo Henan remarked: This refers to Zhang Zhongjing’s discussion on differentiating and treating Taiyin disease. One must carefully examine the signs and symptoms before employing purgation.)
Wang Hu commented: In the aforementioned clause, Zhang Zhongjing did not mention specific decoctions in the "General Principles" (Xu Li). Pang Anshi considered "abdominal fullness" and "dryness of the throat" as definitive signs of a Taiyin heat syndrome, hence stating that Dachengqi Tang is appropriate. Guo argued against immediate purgation because the pulse is deep and fine, suggesting that the stomach may not yet have formed solidified dryness-heat accumulation. Wang Hu further consulted the "Treatise on Cold Damage" (Shanghan Li), which records: For Taiyin disease, the cun and chi pulses are both deep and fine; for Shaoyin disease, they are both deep; for Jueyin disease, they are slightly slow and moderate. Most mentions of pulse patterns were likely added by Wang Shuhe, and errors inevitably occurred during transcription. Theoretically, since the Three Yin meridians are located internally, their pulses should all be deep. How could it be that if Taiyin and Shaoyin pulses are already deep, the Jueyin meridian, being even more internal, would not also be described as having a deep pulse? Upon correction, "cun and chi both slightly slow and moderate" should correspond to Taiyin disease; "cun and chi both deep and fine" should correspond to Jueyin disease. The character "fine" (xi) is a transcription error for "wiry" (xian); "cun and chi both deep" corresponds to Shaoyin disease, requiring no further debate. In cases of Three Yin syndromes where Chengqi Tang is indicated, the deep pulse must necessarily be rapid and forceful. Only in Taiyin disease does the pulse feature a slight slowness/moderation, which represents the subtle art of differentiation and treatment.
Pang Anshi further stated: In cold damage diseases, if the pulse is floating and slow, and the hands and feet are naturally warm, the disease is associated with Taiyin... This is because the Spleen's healthy qi is recovering, and the putrid filth should be expelled. In such cases, Chupi Tang (Tangerine Peel Decoction) should be administered.

Finely chop, add 1.5 sheng of water, boil down to 0.7 sheng, strain off the dregs, and divide into two doses. Drink while slightly warm. If symptoms do not resolve, prepare and administer another dose.
Wang Hu commented: The aforementioned therapeutic principles... originate from Zhang Zhongjing’s original treatise. Zhang Zhongjing stated: "Putrid filth should expel itself," thus providing no specific formula. Pang Anshi’s use of Chupi Tang aims to stabilize the Taiyin, eliminate filth, and support the righteous qi.
