A paste of white flour and vinegar is applied to the swollen area on the exterior of the throat. Alternatively, Phellodendri Cortex (Huangbai) is ground into powder and taken with wine.

Realgar (Xionghuang) is ground into a cup of freshly drawn cold water and ingested to induce vomiting.
Another prescription: A handful of Xanthii Fructus (Can'er), a piece of old ginger, are crushed to extract juice, which is then mixed with wine for ingestion. (If red threads appear on the chest, they should be pricked and severed with a silver needle.)

When a mass forms in the throat, preventing the passage of water and food, causing critical distress and near-death state:
Soot from hundred-grass stoves (Baicaoshuang) is mixed with honey to form pills the size of Euryale Seed (Qianshi). One pill is dissolved in freshly drawn cold water and administered via gavage.

White Chrysanthemum flowers (including roots and leaves) are crushed to extract juice and administered orally, resulting in immediate recovery. Alternatively, seven dried dark plums (Wumei) and fourteen persimmon calyces are decocted for gargling. For all types of throat disorders, juice from Vigna angularis (Baidou) or Sidney juice (Sydney Zhi - likely a specific local remedy or textual variant) are effective. Radish greens can be steamed with sauce or salt to prevent throat ailments.

Heat accumulation in the throat causes swelling around the exterior, accompanied by numbness and itching.
The root strings of Pharbitis Seed (Qianniu) are burned to ash and blown into the throat.

Several swallow nests found on walls are baked on tiles, mixed with a small amount of Borneol (Bingpian), ground into powder, and blown into the throat.

Human fingernails are ground into powder and blown into the throat.
Another prescription: Raw Tung Oil (Shengtongyou) is used to dip a goose feather quill to stir the throat, inducing the expulsion of phlegm. (Simultaneously, sesame oil is applied to the neck and scraped with a copper coin.)

In cases where hands and feet are cold, Qi is obstructed, life hangs in the balance for an instant, and no medicine is available at hand:
Urgently stroke down both arms with hands dozens of times. Tie the head of the thumb tightly with a hair rope. Prick the Shaoshang acupoint (located one cun away from either side of the thumbnail of the thumb). For males, prick the left hand; for females, the right hand. In severe cases, prick both hands. Alternatively, blow Polyporus Umbrellatus (Mabo) powder into the throat. If aphonia occurs, mix fresh radish juice with ginger juice and ingest.

Three qian of Alum (Baifan) is slowly melted over low heat. Two kernels of Croton Seed (Badou) are added after being crushed. Once dry, remove the Badou and use only the Alum powder to blow into the throat, expelling phlegm to achieve cure. If emergency treatment was delayed and only faint breath remains, thread a strip of Badou kernel through the throat, insert it, and pull it out after a short while to restore consciousness.

Jute bark (Jiama Pi, width resembling leek leaves) is cut into seven segments (each segment one cun long). It is ignited in a tobacco pipe, and the smoke is inhaled directly to break up the obstruction. If not broken, inhale again.

This is Hou Bi (Throat Obstruction).
Examine the patient's scalp; if there are red dots within the whorl of hair, prick them open with a needle. Double tonsillar hypertrophy corresponds to two points; single tonsillar hypertrophy corresponds to one point.
Another prescription: The roots and leaves of Isatis Root and Leaf (Malan Gen Ye) can also be crushed to extract juice for drinking.
Additionally, powder from Olive pits (Ganlan He) is blown into the throat, producing a cracking sound and bleeding.
