Ren Shen (Ginseng Radix), Bai Zhu (Atractylodis Rhizoma), Gan Cao (Licorice Radix et Rhizoma, prepared with honey), Gan Jiang (Zingiberis Rhizoma).
The above ingredients are divided into equal parts, processed with refined honey to make pills, where each liang of powder forms five pills. They can be taken by dissolving in warm water or decocted in water for oral administration. If treatment is delayed after the onset, the condition becomes urgent.
In more critical cases where there is no sweating, Fuzi Ganjiang Gancao Tang (Aconite, Dried Ginger, and Licorice Decoction) is suitable. If spontaneous sweating occurs, Fuzi Baizhu Gancao Tang (Aconite, Atractylodes, and Licorice Decoction) is suitable. Based on the pulse and syndrome, one may select Si Ni Tang (Frigid Extremities Decoction), Zhen Wu Tang (True Warrior Decoction), Tong Mai Si Ni Tang (Pulse-Resuscitating Frigid Extremities Decoction), etc., for treatment. The use of Fu Zi (Aconiti Lateralis Radix Praeparata) is a last resort. If the body and four limbs are hot and not cold, or if Jue Ni (cold reversal/extremity coldness) occurs, Fu Zi should not be used. Therefore, Li Zhong Tang/Wan (Regulate the Middle Decoction/Pill) includes the concept of "Si Shun" (Four Smoothnesses). "Li Zhong" refers to regulating the middle jiao. "Si Shun" means the hands and feet remain naturally warm without Jue Ni. If the acute condition is neglected, it becomes even more critical.

In Yin syndromes, when Yang Qi dissipates from within, taking warming and hot herbs may cause extreme restlessness (Fan Zao) and thirst with a desire to drink, which indicates that sweating is about to occur. If people do not understand this, they mistakenly consider it a Heat syndrome! If heat rushes upward to the chest, and after taking warming and hot herbs, the restlessness slightly subsides and there is no desire to drink, it indicates that the Middle Jiao has harmonized. If physicians recognize this, continuing the medication will lead to recovery. In the first scenario, if there was no restlessness at the beginning but restlessness appears after medication, the pulse should be floating, excess, and large, indicating abundant Yang Qi. If the hands and feet are warm, survival is likely; if the floating pulse is deficient and small, it indicates Yang Qi scattering, and Jue Ni leads to death. In the second scenario, if there was restlessness at the beginning but it ceases after medication, the deep pulse should be excess and large, indicating the return of Yang Qi. If the hands and feet are warm, survival is likely; if the deep pulse is deficient and small, it indicates the extinction of Yang Qi, and Jue Ni leads to death. For these two syndromes, if taking warming and hot herbs fails to replenish or restore Yang Qi, the Classics state: this is due to the lack of Fire (Kidney Yang deficiency).
Question: Why does the pulse become large after purgation?
Answer: It is logical for the pulse to become small after purgation. A small pulse still allows for survival, and recovery is easier. Zhang Zhongjing stated: If the pulse becomes large after purgation, it indicates deficiency, and Yang Qi is about to scatter and change. If physicians fail to recognize this and purge again, Qi will diminish, resulting in a severe Yin Cold syndrome! There are also cases of Yin restlessness with continuous fever, extreme thirst desiring cold drinks, heat rushing to the chest, and fire blazing upward alone, which signifies the exhaustion of Yang Qi. Because Yin cold pervades the whole body, only a remnant of fire remains in the chest, allowing Yin to dominate unchecked, forcing this situation. This is consistent with the logic of a large pulse after purgation. A large pulse after purgation shows no other heat signs; Yin restlessness with fever presents only with a small pulse! One case reveals the pulse but not the symptoms; the other reveals the symptoms but not the pulse. Furthermore, the Classics state: Diarrhea with a large pulse indicates deficiency, caused by forced purgation. If the pulse is floating and革 (Ge/Pounding Bamboo), accompanied by borborygmus (intestinal rumbling), it belongs to Dang Gui Si Ni Tang (Angelica Sinensis Resuscitating the Extremities Decoction). Ge pulse indicates cold; the combination of cold and deficiency causes borborygmus.
If sweating fails to resolve the disease and chills worsen, it is due to deficiency, treated by Shao Yao Gan Cao Fu Zi Tang (Peony, Licorice, and Aconite Decoction). If sweating or purgation fails to resolve the disease and restlessness ensues, it is treated by Fu Ling Si Ni Tang (Poria Resuscitating the Extremities Decoction). After sweating and purgation, if there is daytime restlessness preventing sleep but quietness at night, without vomiting, thirst, or exterior syndrome, with a deep and faint pulse and no significant body heat, it is treated by Gan Jiang Fu Zi Tang (Dried Ginger and Aconite Decoction).
