Illuminating the ear canal with fire, the insects will crawl towards the light.

Striking two knife edges together above the ear to make a sound, the insects will crawl out.

Immediately hold your breath; when the breath is full, exhale, then hold it again to force the insect out; or if the insect dies in the ear, slowly hook it out with an instrument. If it has been lodged for a long time without coming out, place fresh cooked chicken meat on the ear opening, and the insect will come out.

Pouring sesame oil mixed with rice straw ash juice into the ear, the insect will come out.

To treat various insects entering the ear that cannot exit:
Bai Fan (Alumen), Xiong Huang (Realgar) (each half liang).
Grind the above herbs into fine powder, mix with sesame oil to form a paste. Each time, take an amount the size of a soap nut seed and insert it into the ear; the insect will come out.

Using peach leaves as a pillow, the insect will exit through the nose, shaped like an eagle's beak, whose name people do not know. When someone encounters a house centipede entering the ear, during extreme itching, they may hit their head against a pillar until blood flows without realizing it, as the itch is unbearable. A house centipede entering the ear often consumes the brain marrow completely and can reproduce. For all such insects, pouring hemp oil into the ear resolves the issue.

Mixing chicken heart blood with raw oil and dripping it into the ear, the insect will come out.

Taking one qian of Chuan Jiao (Sichuan Pepper) powder, soaked in half a zhan of vinegar overnight, after some time, drip it into the ear, and the insect will naturally exit.

Dropping lettuce juice into the ear causes the insect to exit; or placing cut cooked pig heart in the ear, leaving an exit path for the insect, so it comes out naturally.

Grinding Chang Pu (Acorus tatarinowii) into powder, stir-frying it, and wrapping it in cotton while hot to apply to the side of the ear.

To treat bilateral deficiency-type deafness:
Bai Fu Ling (Poria cocos), Shan Yao (Dioscorea opposita) (three liang, stir-fried), Xing Ren (Prunus armeniaca) (deprived of skin and tips, stir-fried, one and a half liang).
Grind the above herbs into fine powder, melt two liang of yellow beeswax and mix to form pills the size of a bullet. Take one pill per dose, chew thoroughly after meals, and swallow with salt water.

To treat deafness:
Shi Chang Pu (Rhizoma Acori Tatarinowii) (one cun), Ba Dou (Seminar Crotonis Tiglii) (one grain, shell removed), Quan Xie (Scorpio) (one piece, toxicity removed).
Grind the above herbs into fine powder, mix with scallion juice to form pills the size of a jujube pit, wrap in cotton, and insert into the ear.

The nose is the open passage of the Lung, governing the pathway for the entry and exit of clear Qi. If Qi and Blood are harmonious, and Yin and Yang ascend and descend normally, respiration will be smooth and harmonious, Ying and Wei Qi will circulate, and the nose will be sensitive enough to distinguish odors. However, if affected by the Six Evils or Seven Emotions, both internally and externally, compounded by dietary irregularities and overwork, causing nasal Qi to fail to diffuse and unblock, leading to obstruction of the clear pathways, disease arises. If accumulated heat lodges in the Yangming channel, forcing blood to flow recklessly, bleeding from the nostrils occurs, termed "Nu" (epistaxis). Heat dries up body fluids, while cold causes brain marrow to flow down; or wind-cold follows Qi entering the meridians upwards, penetrating below the brain, and injecting into the nose, causing rhinorrhea that cannot be controlled, termed "Liu Ti" (runny nose). Or due to cold stagnation and Qi blockage, the nose loses the sense of smell, forming "Bi Zhi" (nasal congestion). Blood vessels gather, lingering for days, becoming more obstructed, transforming into polyps. Or Qi stagnates upwards transforming into evil heat, remaining latent and undissipated, forming "Bi Chuang" (nasal sores); over time, it becomes "Gan" (ulceration), rotting and discharging foul-smelling fluid. Nasal diseases are merely due to wind-heat flow. He Jian stated: Bi Zhi is nasal obstruction. Fire governs abdominal swelling; thus, when heat lodges in Yangming, swelling in the nose causes Bi Zhi. Some mistakenly attribute Bi Zhi to cold because cold governs closure and storage. This is incorrect. When Yang Qi is excessive in the upper part and one lies on one side, the upper orifice opens while the lower closes because the Yangming meridians cross left and right; the left meridian injects into the right orifice, and the right into the left. Thus, if wind-heat stagnates, favoring the left side, the upper orifice may become blocked. "Qiu" refers to clear discharge from the nose. The principles of the Five Elements are subtle; when mild, they follow their original transformation; when severe, they involve their destructive elements. Hence, the classics say: "Excess brings harm, control follows." The I Ching says: "Nothing dries the ten thousand things more than fire." Using fire to smelt metal, extreme heat transforms it back into water. Extreme heat leads to sweating. Therefore, excessive Liver heat causes tearing, Heart heat causes sweating, Spleen heat causes salivation, Lung heat causes rhinorrhea, and Kidney heat causes spitting. The classics state: "Excessive nasal heat produces turbid discharge." It also says: "When Gallbladder heat transfers to the brain, the nose feels pungent." "Bi Yuan" (nasal sinusitis) is characterized by continuous leakage of turbid discharge. All thick and turbid phlegm, saliva, and discharge are caused by extreme heat consuming and melting them. Saying Qiu is due to Lung cold is wrong; merely seeing rhinorrhea and nasal congestion, and noting that Stomach cold worsens it, leads to this misconception. One fails to realize that cold injuring the skin and hair closes the interstices, trapping heat, making pain worse. As for sneezing ("Ti"), it is air spraying from the nose due to itching. The nose is the orifice of the Lung; itching is a manifestation of Fire. Heart fire and evil heat invade the Yangming, manifesting as nasal itching, causing sneezing. Or, deliberately disturbing the nose causes itching and sneezing; disturbance-related itching belongs to Blood. Sneezing upon looking at bright eyes occurs because the eyes contain the essence of the five Zang organs and the true Fire of the Taiyang; brightness agitates the Heart Spirit, generating heat upwards, causing nasal itching and sneezing. Sneezing during the decline of a Shanghan (cold damage) disease occurs because the fierce heat has receded, leaving deficient heat that causes itching; nasal itching triggers sneezing. If wind-heat attacks upwards, causing head and nasal congestion, with a floating pulse but no other symptoms, taking internal medicine to induce sneezing opens the congestion and cures the condition. Pain exacerbated by sneezing, which is unbearable, is due to the force of sneezing attacking and knotting, preventing free flow. These three conditions are all heat patterns, hence different manifestations due to invasion of different meridians. Bi Zhi and itchy sneezing involve heat lodging in the Yangming (Stomach meridian); Qiu and rhinorrhea involve heat lodging in the Taiyin (Lung meridian). Generally, the nose is governed by the Foot-Yangming Stomach Meridian, which crosses left and right and injects into the nostrils. Also, the nose is the orifice of the Lung, so Lung Qi connects to the nose. Evil heat invading these two meridians manifests as nasal obstruction, rhinorrhea, etc., hence the classics say: "When the Heart and Lung have disease, the nose becomes obstructed." Treatment depends on observing which meridian the pathogen has invaded, ensuring correct therapy. Sometimes, external wind-cold exacerbates pain, leading to misdiagnosis as cold and treatment with warming/dispersing agents, occasionally effective. However, this masks heat under cold; heat stagnates, Qi becomes turbid, and clear pathways are obstructed. Use acrid-sweet dispersing agents to open interstices, scatter stagnation, and release Yang heat. Mild cases resolve; severe cases with unresolved stagnation may worsen. Even using cooling/wind-dispersing agents only temporarily relieves symptoms by clearing heat and resolving stagnation. Success depends entirely on assessing the severity of internal/external heat stagnation and using appropriate acrid-warm or acrid-cool herbs. Ultimately, medical success relies on accurate diagnosis and clear understanding of treatment, ensuring recovery.
