干姜（一两） 附子（一枚，生用，去皮，破成八片）
以上两味药。用水三升。煮取一升。去渣，一次性服下。
经过攻下法治疗后，又发汗。白天烦躁不能入睡，夜间却安静。不呕吐，不口渴，没有表证。脉象沉微。身体没有大热。
干姜附子汤主治。按：攻下之后则阴气盛而阳气已虚，再发汗以发散其阳，则虚阳扰乱，所以白天烦躁不能入睡。夜间安静，并非吉兆。只是因为入夜后纯阴当令，衰弱的阳气想要躁动扰乱却无力做到。此法不用甘草，比四逆汤更为峻烈。取其直接破除阴霾，恢复阳气。必须审察无呕吐、口渴、表证，脉象沉微，身体无大热的情况，那么烦躁确为虚阳扰乱所致的烦躁，才可以主治以此方，以免误用。
独自在阴分中自我治疗的孤阴，在阳分中自我扰乱的孤阳。所以用姜、附辅助阳气以配伍阴气。
干姜附子汤原方。加葱白四茎。煎服方法照前。
少阴病下利，白通汤主治。按：少阴病下利，肾中真阳，将要随着下利而亡失。所以用姜、附温补肾阳，而加葱白以升举下陷的真阳。
白通汤原方。加人尿五合。猪胆汁一合。用水三升。煮取一升。去渣。纳入猪胆汁和人尿调和使相得。分两次温服。
少阴病下利脉微者，给予白通汤。下利不止，四肢厥冷，无脉，干呕心烦者，白通加猪胆汁汤主治。
按：少阴病下利，治疗用白通汤，药物本无误。正是因为阴气太盛，与辛热之药格拒不相入。所以加人尿、猪胆汁作为向导，与通脉四逆加猪胆汁汤同义。服药后脉象突然暴出的，是被药力所逼迫，而阳气将泄露无余，仍然主死。脉象微微续接才是正气逐渐恢复，所以可生。
Shengjiang (Radix Zingiberis Preparata, one tael) Fuzi (Radix Aconiti Lateralis Preparata, one piece, used raw, skin removed, broken into eight pieces)
The above two herbs. Boil with three sheng of water. Decoct to obtain one sheng. Remove the dregs and take in a single dose.
After undergoing purgation, sweating was induced again. During the day, there is restlessness and inability to sleep; at night, it is quiet. There is no vomiting, no thirst, and no exterior syndrome. The pulse is deep and faint. The body has no significant heat.
Ganjiang Fuzi Tang (Dried Ginger and Aconite Decoction) is indicated. Note: After purgation, Yin pathogen becomes excessive while Yang Qi is already deficient. Inducing sweating again disperses the remaining Yang, causing deficient Yang to become chaotic, hence the daytime restlessness and insomnia. Nighttime quietness is not an auspicious sign. It merely occurs because pure Yin dominates at night, and the weakened Yang lacks the strength to cause agitation. This formula omits Gancao (Radix Glycyrrhizae Uralensis), making it more potent than Sini Tang (Four Reversal Decoction). Its purpose is to directly break through Yin cold and restore Yang Qi. One must carefully verify the absence of vomiting, thirst, or exterior syndrome, along with a deep, faint pulse and no significant body heat. Only then can the restlessness be confirmed as caused by chaotic deficient Yang, allowing for the safe use of this formula without error.
Solitary Yin self-regulates within the Yin aspect; solitary Yang agitates within the Yang aspect. Therefore, Jiang (Zingiberis Rhizoma) and Fu (Aconiti Radix) are used to assist Yang Qi to harmonize with Yin.
Ganjiang Fuzi Tang (Dried Ginger and Aconite Decoction) original formula. Add four stems of Congbai (Scallion White). Decoct and administer as previously described.
Shaoyin disease (Lesser Yin Disease) with diarrhea is treated with Baitong Tang (White Passage Decoction). Note: In Shaoyin diarrhea, the True Yang of the Kidney is on the verge of exhaustion due to the loss of fluids. Therefore, Jiang and Fu are used to warm the Kidney, while Congbai is added to raise the sinking True Yang.
Baitong Tang (White Passage Decoction) original formula. Add five he of Renao (Human Urine) and one he of Zhuchidan (Porcine Bile). Boil with three sheng of water. Decoct to obtain one sheng. Remove the dregs. Mix in the Zhuchidan and Renao until well combined. Divide into two doses and take warm.
In Shaoyin disease with diarrhea and a faint pulse, administer Baitong Tang (White Passage Decoction). If diarrhea persists, accompanied by cold extremities, absence of pulse, dry retching, and irritability, Baitong Jia Zhuchidan Tang (White Passage Decoction plus Porcine Bile) is indicated.
Note: For Shaoyin diarrhea, using Baitong Tang is pharmacologically correct. However, if Yin pathogen is excessively severe, it may reject the acrid-hot herbs due to incompatibility (Ge Ju). Therefore, Renao and Zhuchidan are added as guides, following the same principle as Tongmai Sini Jia Zhuchidan Tang (Pulse-Returning Four Reversal Decoction plus Porcine Bile). If the pulse suddenly emerges violently after taking the decoction, it indicates that the medicinal force has forced the Yang Qi to leak out completely, which still predicts death. If the pulse gradually returns, it signifies the gradual recovery of Zheng Qi (Upright Qi), indicating survival.
