Radix Glycyrrhizae (Gancao) two liang.
Take the above single herb, add three sheng of water, decoct to obtain one and a half sheng, remove the dregs, take seven ge warm, three times a day.
Using a single herb to treat disease is called a "Qi Fang" (Unorthodox Formula). Radix Glycyrrhizae (Gancao) is the essence of the nine soils; when used raw, it is cool in nature, thus it can purge heat from the Kidney. Its efficacy in treating sore throat lies in its ability to relieve Kidney urgency.
Radix Platycodi (Jiegeng) one liang, Radix Glycyrrhizae (Gancao) two liang.
Take the above two herbs, add three sheng of water, decoct to obtain one sheng, remove the dregs, divide into two doses and take warm.
Radix Platycodi (Jiegeng) has bitter and acrid flavors. Bitterness primarily directs downward, while acridity primarily disperses. Its function is specifically to open and lift the pathogenic heat of the Foot Shaoyin Meridian. Assisted by Radix Glycyrrhizae (Gancao), which carries the medicinal power upward, it can transport the remedy to the affected area like a boat carrying cargo.
Rhizoma Pinelliae (Banxia) (washed), Ramulus Cinnamomi (Guizhi) (bark removed), Radix Glycyrrhizae (Gancao) (roasted) in equal parts.
Take the above three herbs, crush and sieve each separately, then mix them together. Mix with white rice drink and take one cun bi (a square-inch measure) per dose, three times a day. If unable to swallow the powder, simply swallow it.
Banxia San (Pinellia Powder): For sore throat where swallowing is possible, use the powder; where swallowing is difficult, use the decoction. This treats the pathogen of Shaoyin that has rebelled within the meridians and cannot exit via the pivot mechanism, using Rhizoma Pinelliae (Banxia) for treatment.
Rhizoma Pinelliae (Banxia) (washed, broken like a jujube pit) fourteen pieces, Egg (remove yolk, place Banxia inside the shell, add Kujiu/Vinegar).
Take the above two items, place Banxia into the vinegar within the eggshell. Place the eggshell in a knife ring, set over fire, boil three times, remove dregs, take small amounts frequently.
Kujiu Tang (Vinegar Decoction): Treats Shaoyin deficiency of Water failing to nourish the Minister Fire, resulting in sores in the throat and loss of voice. The term "sores" refers to ulcerations. The acrid and slippery nature of Rhizoma Pinelliae (Banxia), assisted by vinegar, acts to劫 phlegm and astringe sores. Even if Yin Fire boils vigorously, it can be subdued by the astringent nature of vinegar, hence the name of the decoction.
Radix Bupleuri (Chaihu) eight liang, Radix Scutellariae (Huangqin) three liang, Radix Ginseng (Renshen) three liang, Fructus Ziziphi Jujubae (Dazao) twelve pieces (torn), Radix Glycyrrhizae (Gancao) three liang, Rhizoma Pinelliae (Banxia) eight liang (washed), Rhizoma Zingiberis Recens (Shengjiang) three liang (sliced).
Take the above seven herbs, add twelve dou of water, decoct to obtain six sheng, remove dregs, decoct again to obtain three sheng, take one sheng warm, three times a day.
Chaihu Tang (Bupleurum Decoction) is not formulated based on exterior or interior syndromes alone. Zhang Zhongjing stated: In Shaoyang disease, inducing sweating leads to delirious speech; inducing vomiting or purgation leads to palpitations and fright. Therefore, it does not directly treat the exterior or interior, but rather regulates Qi, allowing the pathogen to resolve spontaneously.
