[Crude drugs for curing internal injury (NeiShang) caused by improper diet or fatigue in "NeiWaiShangBianHuoLun" and "PiWeiLun"].

In "NeiWaiShangBianHuoLun," written by LiGao in the 13th century, internal injury (NeiShang) caused by emotional strain, improper diet and overwork was compared against external injury (WaiShang) caused by exogenous pathogenic factors. A combination of Aurantii Fructus Immaturus and A tractylodis Rhizoma is used for treating the feeling of stuffiness and fullness in the gastric region (Pi) due to improper diet. For treatment of general debility and lassitude due to emotional strain, improper diet and overwork, BuzhongYiqiTang was invented, in which the combination of Ginseng and Astragali Radix is used to activate and reinforce the Qi-deficiency of PiWei (vital energy or digestive function). LiGao recommended the combination of Bupleuri Radix and Cimicifugae Rhizoma for treating loose tissues due to Qi-deficiency, and to assist drugs for replenishing Qi such as Ginseng and Astragali Radix. These uses of crude drugs for curing internal injury (NeiShang) may be useful for treating modern deficiency syndrome in weak children with atopic disposition and persons with postoperative complications.

[Use of crude drugs in "PiWeiLun" in comparison to those used in "NeiWaiShangBianHuoLun".].

PiWeiLun (Hi-i-ron in Japanese) is a traditional Chinese medical formulary written in the 13th century that discusses endogenous disease. For curing endogenous diseases (Naisho) caused by functional deficiency of pi- and wei qi (Hi-I-Ki-Kyo), PiWeiLun was recommended for QingShuYiQi-Tang (Seisho-ekki-to), Ban-XiaBaiZhuTianMaTang (Hange-byakuju-tsu-tenma-to) and BuZhongYiQiTang (Ho-chu-ekki-to), which are described in NeiWaiShangBianHuoLun (Naigaisho-benwa-ku-ron).A characteristic of PiWeiLun is that it discusses combining the use of Phellodendri Cortex with sweet Qi-tonics (Hoki-yaku) as Ginseng and Atractylodis Macrocephalae Rhizome for improving false heat syndrome (Kyo-netsu) due to yin-deficiency (In-kyo). In PiWeiLun Cimicifugae Rhizome, Angelicae Radux and Atractylodes Rhizome are more frequently used than in NeiWaiShangBianHuoLun.The use of drugs presented in PiWeiLun may be useful to devise new crude drug formulations good for modern deficiency syndrome experienced by persons having post-operative complications.
