(Interior deficiency with irritability, fullness, and delirious speech) After eight or nine days, the disease has progressed and transformed into interior excess. If purgation is mistakenly applied, it leads to chest fullness, increased irritability, fright, inability to turn over due to body heaviness, difficult urination, and the onset of delirium.
Chaihu Jia Longgu Muli Tang (Bupleurum Decoction plus Dragon Bone and Oyster Shell)
The formula combines Banxia (Pinelliae Rhizoma), Chaihu (Bupleuri Radix), Huangqin (Scutellariae Radix), and Dahuang (Rhei Radix et Rhizoma), along with Guizhi (Cinnamomi Ramulus), Fuling (Poria), Renshen (Ginseng Radix), Dazao (Ziziphi Jujubae Fructus), and Shengjiang (Zingiberis Rhizoma Recens). It adds Longgu (Fossilia Ossis Mastodi) and Muli (Concha Ostreae) for their excellent calming spirit effects, and Qian Dan (Lithargyrum) to settle rebellious qi effectively.
(Shaoyang syndrome not yet resolved; see Shaoyang primary disease) The use of purgation in Chaihu syndrome injures the qi first. If the syndrome persists, the original decoction should still be used. One must wait until the patient experiences a shivering sensation followed by steaming perspiration; only then will the heat dissipate and health be restored.
(Exterior unresolved with interior excess; see Shaoyang primary disease) Ten days have passed since the onset, and the condition is not mild. Following purgation, fright and vomiting arise. There is a sense of depression with slight irritability and urgency in the epigastrium. The treatment method requires clearing both exterior and interior simultaneously.
Chaihu Jia Mangxiao Tang (Bupleurum Decoction plus Mirabilite)
(Case attachment: Exterior unresolved with interior excess; Xiao Chaihu Tang see Shaoyang primary disease) By the thirteenth day of cold damage, there is hypochondriac fullness, vomiting, and tidal fever. While resolving the exterior, it is appropriate to attack the interior excess by adding Mangxiao (Natrii Sulfas) to Xiao Chaihu Tang (Minor Bupleurum Decoction).
[Pathway to Taiyin]
(Exterior and interior unresolved) After releasing the exterior without cure, purgation was reapplied. This results in alternating chills and fever, extreme fatigue, thirst, chest and hypochondriac fullness with slight knotting, sweating on the head, irritability, and intermittent dysuria.
Chaihu Guizhi Ganjiang Tang (Bupleurum, Cinnamon Twig, and Dried Ginger Decoction)
Chaihu (Bupleuri Radix) and Guizhi (Cinnamomi Ramulus) are combined to release the exterior. Ganjiang (Zingiberis Rhizoma) assists in warming the interior and strengthening the spleen. Gualougen (Trichosanthis Radix) moistens dryness, while Huangqin (Scutellariae Radix) clears fire. Gancao (Glycyrrhizae Radix) and Muli (Concha Ostreae) act together to gather and consolidate, providing beneficial supplementation.
(Exterior resolved but interior chest binding; see Sunyang damaged disease) More than ten days have passed since the onset of cold damage. Water accumulation binds in the chest, causing stagnation and discomfort. There is no significant body heat, only slight sweating on the head. Using Xiantong Tang (Chest-Expelling Decoction) can eliminate the disease.
(Exterior resolved but interior pi-syndrome [glomus]) Cold damage presents with continuous fever and vomiting. After being treated with other purgatives, the illness remains uncurled. Fullness occurs without pain, resulting in a pi-syndrome. Banxia Xiexin Tang (Pinellia Decoction to Drain the Epigastrium) is indicated.
Banxia Xiexin Tang (Pinellia Decoction to Drain the Epigastrium)
Banxia (Pinelliae Rhizoma) descends rebellious qi, while Renshen (Ginseng Radix) tonifies the middle. Dazao (Ziziphi Jujubae Fructus) and Gancao (Glycyrrhizae Radix) cultivate earth with remarkable efficacy. Huangqin (Scutellariae Radix) and Huanglian (Coptidis Rhizoma) clear fire, while Ganjiang (Zingiberis Rhizoma) warms the interior. Applying both cold and hot properties allows the pi-syndrome to be attacked and resolved.
(Exterior cold unresolved; see Sunyang primary disease) The pulse remains floating, indicating that sweating therapy is appropriate. Although Sunyang symptoms appear alongside Taiyin manifestations, there is no internal organ pathology, only meridian involvement. To resolve the exterior, Guizhi Tang (Cinnamon Twig Decoction) should still be used.
