Bencao Shiyi (Supplement to Materia Medica) states: For bites from Agriolimax agrestis (slug), take Polygonum multiflorum (Liao, smartweed), crush and apply to the wound, and soak in it. Current investigation: Bencao states that Agriolimax agrestis is also known as Yunwo. (Japanese name: "Nachiokuchi".)

Bingyuan Lun (Treatise on the Pathogenesis and Manifestations of Various Diseases) states: Silkworms are creatures raised by humans; their nature is not that of venomous insects. However, they occasionally bite people, causing aversion to cold and severe fever. If not cured for a long time, it may even lead to death. This is a rare anomaly; effective rescue and detoxification methods are crucial.
Xinlu Fang (Newly Recorded Prescriptions) records a prescription for Yuocan (a type of venomous caterpillar) poisoning:
Mix vinegar with rat feces until paste-like, and apply topically.
Another prescription: Mix vinegar with chicken manure ash and apply as a seal.
Guangji Fang (Guangji Prescriptions) treats bites from silkworms and spiders:
Semen Lepidii et Descurainiae (Tinglizi, 4 fen) Semen Cnidii (Shechuangzi, 4 fen) Semen Cuscutae (Tusizi, 4 fen) Sal (Yan, 4 fen)
Crush and sieve the above ingredients, mix with three-year-old aged vinegar into a paste, apply to the wound, three times daily.

Bingyuan Lun states: In the Jiangnan region, there is a venomous insect called Shegong (Shooting Worker), also known as Duanhu (Short Fox) or Yu (Hidden One). It often lives in mountain stream waters. Inside its mouth, there is a transverse bone shaped like a horn bow, black in color, about the size of a large housefly. It has teeth and hair, and exists in male and female forms. Males have two horns at the corners of their mouths, with forked tips capable of flexion and extension. They hibernate in soil during winter; heat rises from them, preventing snow from melting upon contact. In summer, they live in water. When people walk on water surfaces, bathe, or during heavy rains when floodwaters enter homes, these insects follow the water flow. They may stop in hoof prints of cattle or horses on roads. Holding sand, they shoot at human shadows, causing illness. Initially, symptoms may resemble Taiyang disease (Cold Damage affecting the Taiyang channel) or Zhong'e (sudden evil invasion). The patient may feel slightly better in the morning but worsen in the evening. Within three to four days of onset, treatment is still possible. Acute cases die within seven days, moderate cases within fourteen days, and chronic cases within twenty-one days all result in death. Initially, there are no sores, only aversion to cold, alternating chills and fever, and pain severe as if pierced by needles. Severe cases develop sores resembling black bean-sized spots, burns, or wounds from earwig secretions. All involve perforations in the flesh, similar to holes made by moxibustion needles.
Baopuzi states: Duanhu is also known as Yu, Shegong, or Sheying. Its actual form in water resembles a cicada but is as large as a three-he cup. It has wings and can fly, has no eyes but sensitive ears, etc.
It further states: Shegong hibernates in valleys during winter. During heavy snow, look for areas where snow does not melt due to rising heat like steam. Dig there, not deeper than one chi underground, to find it. Dry it in the shade, powder it, and carry it to ward off Shegong in summer.
Duanju Fang states: Shegong is also known as Duanhu and Xidu (Stream Poison). Its shape resembles a beetle, with a long horn protruding horizontally before its mouth, covered like a crossbow guard. Curved like a drawn bow, it uses qi as arrows and water current as propulsion to shoot at people. When shooting, one might hear a "bi-bi" sound in the water. It must submerge its mouth in water to shoot. On dry land, it can be handled playfully without harm. These insects hatch in April; toxicity is mild in May and June, causing slow reactions. Toxicity peaks in July and August, causing urgent and severe symptoms. By September, with cold dew and light frost, toxicity declines, ceasing entirely by October. These insects fear geese, which eat them; hearing goose sounds keeps them away. Water flowing with the scent of bathing geese, goose droppings, or feathers cause them to flee. When boating into streams, bring geese along. Households near mountain streams keep white geese. Those entering mountain streams for logging should carry goose droppings and feathers for protection. These insects have keen hearing but poor vision. When people enter stream sources to fetch water or bathe, or wade across, they should throw stones or wood into the water from a distance to create noise. The insects will shoot vacuously at the sound, expelling their toxin. Throw water widely to left and right until the insect releases all toxins, then cross. Such insects are common in mountain sources. During heavy floods, they drift into homes or settle in hoof prints on roads. People walking on land often fail to notice, especially when gathering firewood or bamboo. Victims may misdiagnose the condition and die due to incorrect treatment. Initial symptoms of Shegong envenomation include chills, fever, aversion to cold, dyspnea, muscle spasms, stiffness, headache, and eye pain, resembling Cold Damage or corpse-possession syndrome (Zhongshi), leading to aphonia. Patients may feel slightly better in the morning but worsen in the evening, suffering from oppressive chills and fever. Within three to four days, survival is possible. Acute cases die in seven days, moderate in fourteen, and chronic in twenty-one. Small insects have mild toxicity and do not immediately form sores, often going unrecognized. Large insects have potent toxicity and cause immediate sores. Sores initially appear as black bean-like spots, burns, or earwig-wound-like lesions. Pain is needle-like. Even before visible sores, flesh perforations resembling moxa burn holes may occur. Distant shots or shadow-shots have milder toxicity. Shots to the upper body close to the source are often fatal. Shots to the lower body are less severe. Even if not fatal, recovery is not guaranteed within one hundred days. Treatment follows below.
