《武威漢代醫簡》簡42-43記「治魯氏青行解解腹方」一則，有關「行解」 一詞之訓釋，過去學者多有討論，然卻意見紛紜：王輝以為「行」為步行、散步之意，「行解」乃指通過步行的方式使藥性得以發泄，從而驅除體內寒熱邪毒；而杜勇認為「行解」為「不以發汗為目的」的治療傷寒的一種方法；此外，日本學者赤堀昭氏釋「行解」為「漸解」，有逐漸痊癒之意；段禎亦訓 「行解」 中之 「行」 相當於現代漢語之 「就」，「行解」即「即解」。
然而，倘若細察古籍文獻，「行」於醫典中時可作為「利（痢）」之量詞，而「行清」一詞亦時見。因此，本文疑方劑中之「行解」乃是一種治療方法，主要是透過大、小便之排泄，排出體內之病邪，以達解表散寒之療效。

A prescription titled“zhi lushiqing xingjie jiefu fang＂(治魯氏青行
解解腹) was found in the medical manuscripts unearthed from Wuwei,
Gansu province. Regarding the meaning of“xingjie＂(行解), although
several discussions had already been made, there still exists a wide spectrum
of opinion among scholars. For example, Wang Hui interpreted the word
“xing＂(行) as“taking a walk,” and “xingjie＂therefore means to exert
drug efficacy and cleanse toxic fever and chills out of body through walking.
Du Yong defined“xingjie＂as the treatment for exogenous febrile disease
without the aid of perspiration. Akabori Hiroshi, a Japanese scholar,
explained “xingjie” as the process of “gradual relief” from diseases. Duan
Jing also interpreted the character “xing” in “xingjie” with modern Chinese
word “jiu＂(就) and“xingjie＂thus refers to“relieve immediately.＂
However, with a more detailed analysis in ancient Chinese texts, we
could find the word“xing＂was used as classifiers of“li＂(痢 means
“dysentery”) in traditional medical literature. This paper hence considers
“xingjie＂should be a therapy aiming to relieve superficies and dispel cold
and to drive body’s sickness out through the excretion of feces or urine.
