Scrophulariae Radix (Xuan Shen) 1 qian, Cimicifugae Rhizoma (Sheng Ma) 8 fen, Bombyx Batryticatus (Bai Jiang Can) 1 qian, Arctii Fructus (Niu Bang Zi) 1 qian, Forsythiae Fructus (Lian Qiao) 1 qian, Saposhnikoviae Radix (Fang Feng) 5 fen, Scutellariae Radix (Huang Qin) 6 fen, Coptidis Rhizoma (Chuan Lian Lian).

The above herbs are chopped and taken as one dose. Add two zhong of water, decoct until reduced to eight parts. Gargle while slightly warm, and swallow slowly from time to time. Chen Zhongchun treated throat lichen (Hou Xuan) by adding Fritillariae Bulbus (Bei Mu) and Polygonati Odorati Rhizoma (Tian Hua Fen).

Regarding various throat disorders, historical examination of decoctions reveals the frequent use of acrid-dispersing and salty-softening methods to dispel wind-phlegm and resolve heat-toxin. The method of gargling and swallowing saliva is often employed, prioritizing symptomatic relief (biao) over treating the root (yin).

Realgar (Xiong Huang), Zanthoxyli Fructus (Zhu Ya Zao Jia) (peeled and seeds removed), Veratri Rhizoma (Li Lu) (peeled, using the kernel), in equal proportions.

The above three substances are pounded and ground into a powder. First, hold a mouthful of water in the mouth. Take approximately one zi amount of the medicine and insufflate it into the nose. Immediately spit out the water. After a short while, when salivation occurs, recovery is immediate. Recorded in *Beiji Qianjin Yaofang* for strangling throat wind (Chan Hou Feng).

The throat is the gateway of qi. It connects upward with lung qi. If heat closes off the throat, swelling surrounds the exterior causing neck enlargement, accompanied by numbness or itching, making it difficult to even drink water.

Salpetre (Ma Ya Xiao) 1.5 liang, Bombyx Batryticatus (Bai Jiang Can) 2.5 qian, Borax (Peng Sha) 5 qian, Borneolum Syntheticum (Pian Nao) one zi.

The above medicines are powdered. Using a paper tube, insufflate five fen of the powder into the throat, and healing will occur immediately.

"Key" (Yao Chi) metaphorically describes the miraculous efficacy in treating throat diseases. If wind-pathogen lodges between the throat, qi stagnation transforms into heat, obstructing flow and causing sore throat; if fire-pathogen arises from the Lung and Stomach, wind-toxin knots and swells causing throat pain; if Kidney deficiency exists below, with Yang floating upward, it causes sore throat; if alcohol consumption leads to damp-heat, with Spleen-Stomach damp-heat attacking upward, it causes sore throat. Although the pathogenic factors differ, they all affect the Lung. Salpetre is used; it is the refined crystal of Mirabilite (Pu Xiao) formed in the upper body, light and clear in nature, and salty in taste. When heat invades internally, it is treated with salty-cold agents. Bombyx Batryticatus absorbs pure transforming qi to remove wind-phlegm. Borax is bitter and salty, eliminating upper-jiao heat-phlegm, clearing throat swelling and pain. Su Song praised Borax as an essential herb for treating the throat. Borneolum Syntheticum is highly acrid, enters the Lung meridian, and moves freely, dissipating heat and breaking knots. Insufflating this medicine into the throat disperses fire and eliminates wind, providing immediate pain relief. This approach addresses only the symptoms (biao), not the root cause, but remains an excellent emergency method.
