【方歌】射工伤人必痒痛，甚则骨肉烂成疡，豆豉捣敷白芷洗，
已烂海螵蛸末良。
【注】射工，即树间杂毛虫也，又名瓦刺虫。人触着，则能放
毛射人，初痒次痛，势如火燎，久则外痒内痛，骨肉皆
烂，诸药罔效。用豆豉清油捣敷痛痒之处，少时则毛出
可见，去豆豉用白芷煎汤洗之。如肉已烂，用海螵蛸末
掺之即愈。
【方歌】蚯蚓咬伤受毒气，眉髯脱落全无迹，法用盐汤频频洗，
久则其毒自然去。
【注】蚯蚓咬伤，即受蚯蚓之毒。令人眉髯皆落，状如大麻风
，但夜则蚓鸣于体中为异耳。宜用盐汤频频洗之，其毒
自去。
【方歌】天蛇疮发肌肤中，似癞非癞是其形，证因草内蜘蛛毒，
复被露水侵始生。
【注】此证生于肌肤，似癞非癞，是草中花蜘蛛蟞伤，复被露
水所侵而致。法宜秦艽一味煎汤，徐徐饮之；外敷二味
拔毒散甚效。
方剂：二味拔毒散（见肿疡门）
【方歌】蠼〔虫叟〕隐壁尿射人，误着皮肤水疱淫，痛如火烙如
豆大，盐汤二味拔毒侵。
【注】此虫一名多脚虫，藏于壁间，以尿射人。若误中其毒，
令人皮肤起燎浆水泡，痛如火烙，初如饭糁，之如豆大
。宜盐汤绵塌疮上，数换即消；甚则毒延遍身，搔痒不
休，宜二味拔毒散敷之甚效。

[Verse] Those bitten by the Shegong insect (a type of toxic bug) will inevitably experience itching and pain; in severe cases, flesh and bone may rot into ulcers. Apply crushed fermented soybean (Douchi) externally, and wash with Angelica dahurica (Baizhi) decoction. If the skin is already ulcerated, applying cuttlebone (Haipiaoxiao) powder is effective.
[Note] The Shegong insect refers to various hairy bugs found in trees, also known as Waci insect. Upon contact, it can shoot toxic hairs at humans. Initially, there is itching followed by pain, feeling like a burn. Over time, external itching and internal pain occur, leading to the rotting of flesh and bone, rendering most medicines ineffective. First, apply a paste of fermented soybean (Douchi) and refined oil to the painful and itchy area; after a short while, the toxic hairs become visible. Remove the paste and wash the area with a decoction of Angelica dahurica (Baizhi). If the flesh has already rotted, sprinkling cuttlebone (Haipiaoxiao) powder on the wound leads to recovery.
[Verse] Bitten by an earthworm, one receives toxic qi, causing eyebrows and beard hair to fall out without trace. The method is to frequently wash with salt water; over time, the toxicity naturally dissipates.
[Note] An earthworm bite involves exposure to earthworm toxicity. It causes the loss of eyebrows and beard, resembling leprosy, except for the peculiar sensation of hearing worms chirping inside the body at night. It is advisable to frequently wash the affected area with salt water, allowing the toxicity to naturally leave the body.
[Verse] Tianshe Chuang (Heavenly Snake Sore) erupts within the skin; its appearance resembles leprosy but is not true leprosy. This condition arises from spider venom in the grass, compounded by dew infiltration.
[Note] This condition manifests on the skin, appearing similar to leprosy but distinct. It is caused by bites from flower spiders (Xie) in the grass, further aggravated by exposure to dew. The treatment should involve drinking a decoction of Gastrodia elata (Qinjiao) alone slowly; externally, applying Erwei Badu San (Two-Ingredient Antidote Powder) is highly effective.

[Verse] Qu Sou (a multi-legged bug) hides in wall crevices and sprays urine at people. Accidental contact causes large blisters on the skin. The pain feels like a hot iron brand, starting the size of a rice grain and growing to the size of a bean. Treat with salt water and Erwei Badu San.
[Note] This insect, also called Duojiao Chong (multi-legged bug), hides in wall gaps and sprays urine at humans. If poisoned by its urine, it causes blistering on the skin with pain akin to branding with fire. Initially, lesions are the size of rice grains, later enlarging to the size of beans. It is suitable to apply salt water-soaked cotton to the sores, changing it frequently until they subside. In severe cases where toxicity spreads over the whole body with incessant itching, applying Erwei Badu San externally is very effective.
