Indicated for Jueyin disease (Disease of the Jueyin channel) presenting with dry retching, vomiting of saliva and froth, and headache. It is also indicated for Shaoyin disease (Disease of the Shaoyin channel) presenting with vomiting and diarrhea, coldness of the hands and feet, and severe restlessness bordering on death.
When one desires to vomit upon eating grain, it belongs to Yangming disease (Disease of the Yangming channel), and Wuzhuyu Tang (Evodia Decoction) is indicated. If the condition worsens after taking the decoction, it indicates a location in the Upper Jiao (Upper Burner).
Wuzhuyu (Evodiae Fructus, 1 sheng, washed)
Renshen (Ginseng Radix et Rhizoma, 3 liang)
Shengjiang (Zingiberis Rhizoma Recens, 6 liang)
Dazao (Jujubae Fructus, 12 pieces)
The above four ingredients are boiled in 7 sheng of water until 2 sheng remains. The dregs are removed. Take 7 ge warm, three times a day.
Song says:
One sheng of Wuzhuyu and three liang of Renshen,
Six liang of Shengjiang to rescue from cold invasion.
Twelve Dazao govern the Middle Palace (Spleen/Stomach),
Seek relief for vomiting, diarrhea, headache, and restlessness.
Commentary by Wei (Chen Nianzu): The organs of Shaoyin rely on the water and grain from Yangming for nourishment and generation, and they intersect with the Central Earth (Spleen/Stomach). If there is upper vomiting and lower diarrhea, the Central Earth becomes severely deficient. When the Qi of Shaoyin fails to ascend and connect properly, it manifests as agitation; in severe cases, it leads to extreme restlessness bordering on death. This formula uses the large acrid and large warm nature of Wuzhuyu to rescue the nearly exhausted Yang Qi, assisted by the harmonious nature of Renshen to stabilize the Middle Qi. Shengjiang and Dazao harmonize the Stomach to circulate Qi and Blood to the four extremities. The physician, unwilling to sit idly by when facing seemingly incurable conditions, seeks treatment specifically through the Yangming Stomach. This achieves the miracle of finding life in a desperate situation. Therefore, this formula stands in parallel with Tongmai Sini Tang (Pulse-Returning Decoction) and Baitong Plus Porcine Bile Decoction. The Treatise states: "Those who desire to vomit upon eating grain belong to Yangming," treated with Wuzhuyu Tang. Wuzhuyu is the specialized herb for the Jueyin channel, yet its ability to warm the middle and dispel cold makes it applicable to all three Yin channels (Taiyin, Shaoyin, Jueyin). Assisted by Renshen, Shengjiang, and Dazao, it becomes a divine prescription for rescuing the failure of Stomach Yang. Hence, the ancient sages taught "to discuss the formula rather than individual herbs."
Indicated for Shaoyin disease presenting with diarrhea, sore throat, chest fullness, and irritability.
Zhufu (Porcis Cutis, 1 jin)
The above single ingredient is boiled in 1 dou of water until 5 sheng remains. The dregs are removed. Add 1 sheng of Baimit (White Honey) and 5 he of Baifen (White Powder/Rice Flour), boil until fragrant, mix well, and take warm in six divided doses.
Song says:
Boil one jin of Zhufu in one dou of water,
Reduce by half and discard the dregs.
Then add Baifen (Five he) and Baimit (One sheng),
Boil until fragrant and take.
Zhang Lingshao (Zhang Yinan) said: This formula, combined with the following four formulas, all utilize Shaoyin as the pivot to rotate internal and external aspects without cessation. Reversal leads to disease. Shaoyin has Fire above and Water below. When Water and Fire do not interact, the Spirit Mechanism cannot pivot, resulting in chest fullness. When the Spirit Mechanism is internally constrained, it results in irritability. The pig is an animal of Water; Zhufu (pig skin) is used because it can permeate the entire body, symbolizing both moving from inside out and outside in. Honey represents the flavor of Grain/Earth (Ji Se); Baifen is the essence of the five grains. Boiling until fragrant aims to use the aroma to assist the Central Earth in interacting Water and Fire, thereby rotating the pivot mechanism.
