The tongue is the sprout of the Heart and connects with the five Zang organs. When toxin-heat invades, manifestations first appear on the tongue. Redness, purpleness, blackening, swelling, protrusion, and fanning of the tongue are all best treated by clearing heat and using rhinoceros horn (Xijiao) to calm the condition.
[Note] The tongue is the sprout of the Heart and internally connects with the five Zang organs. When toxin-heat erupts, the tongue is affected first, presenting as red, purple, black, or swollen, or showing protrusion and fanning movements. These various manifestations are all caused by heat lingering in the Heart. Treatment should primarily focus on clearing heat, using Jiawei Xijiao Tang (Modified Rhinoceros Horn Decoction).
Jiawei Xijiao Tang (Modified Rhinoceros Horn Decoction)
Jingjie (Schizonepetae Spica), Fangfeng (Saposhnikoviae Radix), Niubangzi (Arctii Fructus, stir-fried), Sheng Gancao (Raw Glycyrrhizae Radix et Rhizoma), Jiegeng (Platycodonis Radix), Shengma (Cimicifugae Rhizoma), Xijiao (Rhinocerotis Cornu), Maidong (Ophiopogonis Radix, heart removed), Zhizi (Gardeniae Fructus), Huanglian (Coptidis Rhizoma), Shigao (Gypsum Fibrosum).
Decoct in water and take orally.
[Fangge] Jiawei Xijiao Tang disperses heat; Jingjie, Fangfeng, Niubangzi combined with Gancao and Jiegeng; Shengma, Xijiao, and Maidong; Zhizi, Huanglian, and Shigao act swiftly.
The throat and pharynx govern the entry and exit of air and food. When toxin-fire rushes upward and blazes fiercely, pain becomes unbearable. Internally, use Ganjie Wanjie Ji (Licorice and Platycodon Throat-Soothing Formula); externally, apply Niuhuang San (Calculus Bovis Powder) for immediate relief.
[Note] The pharynx (Yan) is the pathway for food and drink; the larynx (Hou) is the gate for respiration. This is a most critical area. If the pox-toxin cannot vent outward, fire-heat obstructs the diaphragm and rushes upward to the throat, it may cause swelling and pain, hoarseness, or choking, and in severe cases, difficulty breathing and inability to swallow food or drink. Quickly treat with Jiawei Ganjie Tang (Modified Licorice and Platycodon Decoction). Alternatively, use Jiajian Liyan Jiedu Tang (Modified Throat-Soothing and Toxin-Clearing Decoction), and externally apply Niuhuang San (Calculus Bovis Powder) to the swollen area.

Liyan Jiedu Tang (Throat-Soothing and Toxin-Clearing Decoction)
Fangfeng (Saposhnikoviae Radix), Shandougen (Sophorae Tonkinensis Radix), Maidong (Ophiopogonis Radix, heart removed), Niubangzi (Arctii Fructus, stir-fried), Heishen (Scrophulariae Radix, processed), Ku Jiegeng (Bitter Platycodonis Radix), Sheng Gancao (Raw Glycyrrhizae Radix et Rhizoma), Lüdou (Phaseoli Radiatus Semen).
Decoct in water and take orally.
[Fangge] For soothing the throat and clearing toxins, use Fangfeng; combine with Shandougen and Maidong; Niubangzi, Heishen, and Ku Jiegeng; decoct together with Gancao and Lüdou to make a concentrated liquid.
Niuhuang San (Calculus Bovis Powder)
Chuan Huanglian (Raw Coptidis Rhizoma), Huangbai (Phellodendri Cortex, raw), Bohe (Menthae Haplocalycis Herba) (each 8 fen); Xionghuang (Realgar), Huoxiao (Saltpeter), Qingdai (Indigo Naturalis) (each 2.5 fen); Niuhuang (Calculus Bovis), Bingpian (Borneolum Syntheticum), Pengsha (Borax), Zhusha (Cinnabaris) (each 1 fen).
