The *Bing Yuan Lun* (Treatise on the Origins and Manifestations of Diseases) states: Ma Hou Bi (Horse Throat Obstruction) refers to heat-toxic qi accumulating in the throat, with swelling extending to the cheeks accompanied by slight high fever, mental restlessness and fullness, and frequent exhalation. This is called Ma Hou Bi.

The *Qian Jin Fang* (Essential Prescriptions Worth a Thousand Gold) states: When throat obstruction involves severe swelling extending to the cheeks and rapid breathing, it is named Ma Hou Bi. The prescription for treating it is:
Take one horse bit (Ma Xian), boil in three sheng of water until reduced to one sheng, and divide into three doses.
Another prescription: Take a handful of roots of *Verbena officinalis* (Mabiancao), avoid exposure to wind, cut off both ends, crush to extract juice, and take orally.

The *Long Men Fang* (Dragon Gate Prescriptions) treats Ma Bi with the following prescription:
Take roots of *Iris lactea* (Malincao), wash thoroughly, burn into ash (one chi), obtain dripping juice from burning jujube branches, mix with the ash, stir, and drink; recovery will be immediate.

The *Bing Yuan Lun* states: Heat in the Spleen and Stomach causes qi to rush upward, resulting in swelling and pain of the throat and pharynx.

The *Ge Shi Fang* (Prescriptions of Master Ge) treats sudden abscesses of the throat and pharynx with inability to eat or drink: Use one bunch of Chinese chives (*Allium tuberosum*), crush and cook/warm them, then apply to the swelling; replace when cool. Mixing with vinegar (Ku Jiu) is also good.
Another prescription: Swallow two seeds of Coix seed (Yiyi Zi).
Another prescription: Burn *Elaeagnus* wood (Jingmu), obtain its juice, and slowly swallow and gargle with it.
Another prescription: Red-heat a weight (Chengchui), immerse it in two sheng of vinegar, wait until boiling stops, then take the liquid to drink.

The *Seng Shen Fang* (Prescriptions of Monk Shen) treats sudden swelling and pain of the throat and pharynx where swallowing saliva is impossible, using Shengma Han Wan (Cimicifuga Lozenge) to clear heat and descend rebellious qi:
Fresh Ye Gan Juice (Liu he) Angelica sinensis root (Danggui, one liang) Cimicifuga herba (Shengma, one liang) Licorice root (Gancao, three fen)
These four ingredients are finely powdered and sifted, formed into pills using Ye Gan juice. Wrap each pill in cotton like a bullet, hold in the mouth to slowly swallow the juice, three times during the day and once at night.

The *Qian Jin Fang* treats sudden swelling of the throat with inability to eat or drink: Hold high-quality vinegar (Cu) in the mouth; this is also effective for sores on the mouth and tongue.

Boil these five ingredients in five sheng of water until reduced to one and a half sheng, and divide into three doses.

The *Bing Yuan Lun* states: Shi Yan (Corpse Throat) refers to corpse-worms within the abdomen moving upward to erode the throat and pharynx, causing ulcers. The condition presents as itching or pain, resembling the sensation after eating sweet food.

The *Jiu Ji Dan Yan Fang* (Emergency Single Verified Prescriptions) treats Shi Yan: Crush dried ginger (Ganjiang) mixed with salt powder and apply/insert into the affected area; recovery will be immediate.
