Treat Shaoyin disease (Shaoyin syndrome), occurring two to three days or more after onset, characterized by vexation in the heart and inability to lie down.
Coptidis Rhizoma (Huanglian) four liang, Scutellariae Radix (Huangqin) one liang, Paeoniae Radix Alba (Shaoyao) two liang, Yolk of Chicken Egg (Jizihuang) two pieces, Euphorbiae Concretio (Ejiao) three liang. The above five herbs:
Boil the first three herbs in five sheng of water, reduce to two sheng, remove dregs, add Ejiao until completely melted, allow to cool slightly, add Yolk of Chicken Egg,
Stir well to mix, take seven ge warm, three times a day.
[Collected Notes] Ke Qin said: This is a Xixin Tang (Heart-Draining Decoction) formula for Shaoyin disease. Whenever Xixin methods are used, Huanglian and Huangqin are indispensable, but the guiding methods differ between Yin and Yang. When the disease is in the Three Yang meridians, with disharmony in the stomach leading to fullness and hardness below the heart, deficiency requires adding Ginseng Radix et Rhizoma (Renshen) and Glycyrrhizae Radix et Rhizoma Preparata (Gancao) to tonify, while excess requires Rhei Radix et Rhizoma (Dahuang) to purge. When the disease is in the Shaoyang meridian, presenting with vexation in the heart and inability to lie down, neither Renshen and Gancao should be used to assist Yang, nor Dahuang to damage the Stomach Qi. Here, Huangqin and Huanglian are used to directly subdue Heart Fire, Ejiao is used to tonify Kidney Yin, Yolk of Chicken Egg assists Huangqin and Huanglian to tonify Heart Blood while draining Heart Fire, and Shaoyao assists Ejiao to astringe Yin Qi while nourishing Yin. Thus, Heart and Kidney interact, Water ascends and Fire descends. Therefore, this formula, originally supporting Yin and draining Yang, transforms into an agent that nourishes Yin and harmonizes Yang. In this way, the Fire of Shaoyin returns to its proper place, and the vexation in the heart with inability to lie down can be eliminated. The Classic states: "When Yin is peaceful and Yang is secure, Spirit becomes regulated." Does not this formula exemplify this?

Treat dysfunction of Middle Jiao Qi transportation, feeling of emptiness in the abdomen, loss of taste, prolonged illness with anorexia, disharmony of Zang-Fu organs, as well as symptoms such as direct invasion of Taiyin by Cold Damage pathogens, spontaneous diarrhea without thirst, excessive cold with vomiting.
Ginseng Radix et Rhizoma (Renshen) three liang, Atractylodis Macrocephalae Rhizoma (Baizhu) three liang, Glycyrrhizae Radix et Rhizoma Preparata (Gancao) three liang, Zingiberis Rhizoma Recens (Ganjiang) three liang. The above four herbs:
Pulverize and sieve, make pills with honey the size of a Chicken Egg Yolk. Dissolve one pill in several he of boiling water, crush, and take warm. Three times a day, four pills each time; at night, two pills each time. If there is no warmth in the abdomen, increase to three or four pills per dose. However, this is inferior to the decoction method. The decoction method: slice the four herbs according to the specified weights,
Boil in eight sheng of water, reduce to three sheng, remove dregs, take one sheng warm, three times a day. If there is a pulsating sensation above the navel, indicating Kidney Qi movement, remove Baizhu and add Cinnamomi Ramulus (Guizhi) four liang. For excessive vomiting, remove Baizhu and add Zingiberis Rhizoma (Shengjiang) three liang. For excessive diarrhea, continue using Baizhu. For palpitations, add Poria (Fuling) two liang. For thirst desiring water, increase Baizhu to a total of four and a half liang. For abdominal pain, increase Renshen to a total of four and a half liang. For cold signs, increase Ganjiang to a total of four and a half liang. For abdominal fullness, remove Baizhu and add Aconiti Lateralis Radix Praeparata (Fuzi) one piece. After taking the decoction, approximately the time it takes to eat a meal, drink about one sheng of hot porridge to induce slight warmth; do not induce sweating or adjust clothing/bedding excessively.
[Collected Notes] Cheng Yingmao said: The activity of Yang begins with warming. When warming Qi is effective, grain essence is transported; when Grain Qi ascends, Middle Qi is sufficient. Hence it is named Lizhong (Regulating the Middle), actually employing the function of regulation to provide Yang Qi to the Middle Jiao. If Stomach Yang is deficient, Middle Qi loses its control, Danzhong (Conception Vessel area/Chest) loses its dispersing function, and the Six Fu organs lose their sprinkling and arranging function. It is like a stove losing its fire, thus leading below to undigested food in stool (Qingu) and above to loss of taste. The mutual encroachment of the Five Zang organs causes these various symptoms. Renshen, Baizhu, and Prepared Gancao guard the Central State (Middle Jiao); Ganjiang is pungent and warm to heat the middle. It must borrow its flame-like property to stoke the stove's fire and raise Yang Qi. Thus, grain enters the Yin, generates Qi in the Yang, transports upward to the Huagai (Lungs/Heart), and secures downward to the Zhoudou (Bladder). The Five Zang and Six Fu organs all receive Qi from this. This is the purport of Lizhong. If Water and Cold compete mutually, both Spleen and Kidney should be warmed simultaneously; adding Fuzi warms the Mother of Earth (Spleen) via the Mingmen Fire. Baizhu tonifies the Spleen; combined with Renshen, it may cause Qi stagnation, leading to Qi movement below the umbilicus. For excessive vomiting and abdominal fullness, Baizhu is removed. Guizhi is added to suppress Kidney pathogenic factors, Shengjiang is added to stop vomiting, and Fuzi is added to eliminate Yin-Cold. Excessive diarrhea indicates dampness excess, so Baizhu is used again to dry dampness. Thirst desiring water indicates fluid insufficiency; adding Baizhu helps transform fluids. Palpitations below the heart indicate water retention; Fuling is added to guide out water. Abdominal pain doubled with Renshen indicates deficiency pain. Cold signs require increased Ganjiang for severe cold.
