治疗小儿牙疳。《集验方》：将铜绿水飞、雄黄水飞、五倍子炒至焦黑、枯矾、白褐烧至存性、乌梅肉炙干、细辛去叶芦后炒焦、胡黄连炒焦，共八味药，各取等份。用老茶叶和葱根煎汤，以鸡毛蘸汤洗去腐肉，直到见到鲜血，然后用此药粉搽涂患处。
《粤山录》记载：出自新安南地区，头罾本是用苎麻织成的，渔妇将其破旧的剪成条状，作为纬线，以棉纱为经线，用锻石煮染，在溪水中漂洗，去除原来薯莨染上的颜色，使其洁白如雪。布分为双单两种，双面的表里都有大小絮头，单面的一面有絮头。絮头以长的为珍贵，长时间抚摸，蓬松柔软如同西毡，起绒的更好。或者用薯莨染色，则丝线劲爽，可做夏装；不染色则柔软，用于御寒。广东人非常珍视它，也是一种奇特的布匹。小儿服用（指某种与红绒相关的制剂或误植，原文语境稍显突兀，此处直译），可以辟除邪魅。
治疗疳毒。《外科正宗》：治疗下疳，用油透罗缎旧帽沿烧成灰，杭粉在瓦上焙至黄色，两者等分，研成极细粉末。先用十五枚红枣和三钱甘草煎汤清洗患处，然后掺入药粉。
金疮（金属利器造成的创伤）。《集验方》：用旧毡帽油口沿烧成灰，掺敷伤口，即可痊愈。
绵有木棉、丝棉两种，只有丝棉制成的制服会有“丝珠”（丝棉结块），新制的衣服常常有丝珠透出衣外；周履靖在《群物奇制》中说：伏天装的绵布衣没有丝珠，秋冬则有，在绵上放少许灯草，就不会有丝珠了。入药用的是旧衣服内的绵珠，取其沾染人气已久。新衣服透出衣外的绵珠没有用处。治疗蝎虎（壁虎）咬伤，用香油调匀涂抹，效果神奇。
治疗秤勾疮。这种症状是小儿出生后一个月内肛门处突然长出疮孔，就是此症。《救生苦海》：用红绒烧灰二钱，珍珠五分，轻粉五分，儿茶二钱，血竭一钱，乳香一钱，研为末，干掺于患处。
To treat pediatric noma (gangrenous stomatitis). *Ji Yan Fang* (Collected Proven Prescriptions): Copper green water-washed, realgar water-washed, gallnut stir-fried until charred, burnt alum, white silk floss burned to retain its properties, dried tamarind flesh roasted dry, asarum with leaves and rhizomes removed and stir-fried until charred, picrorhiza stir-fried until charred. These eight ingredients are taken in equal proportions. Decoct old tea leaves and scallion roots in water. Use a chicken feather dipped in the decoction to wash away necrotic tissue until fresh blood appears, then apply this medicinal powder to the affected area.
*Yue Shan Lu* records: Originating from Xin'an Nan, the head net was originally woven from ramie. Fishwives cut their worn-out pieces into strips, used them as weft, and warp them with cotton yarn. They were boiled with iron oxide dye, bleached in stream water to remove the previous color dyed by Chinese sumac, making them bright white. The cloth is divided into double and single types. Double-sided cloth has large and small floss knots on both front and back; single-sided cloth has them on one side. Floss knots that are longer are considered more valuable. Rubbing it for a long time makes it fluffy and soft like western felt; those with raised pile are even better. If dyed with Chinese sumac, the threads become crisp and refreshing, suitable for summer wear; if undyed, they remain soft for warmth. People in Guangdong highly value it; it is also a peculiar cloth. Children taking it can ward off evil spirits.
To treat gan toxicity. *Wai Ke Zheng Zong* (Orthodox Manual of External Medicine): For chancre, burn the brim of an oil-stained straw hat made of fine gauze to ash. Roast Hang powder on a tile until yellow. Mix these two in equal proportions and grind into an extremely fine powder. First, wash the lesion with a decoction of fifteen red dates and three qian of licorice root, then sprinkle the powder.
Metal weapon wounds (*Ji Yan Fang*): Burn the oil-stained brim of an old felt hat to ash and sprinkle it on the wound; it will heal.
Cotton fiber comes in two types: kapok and silk cotton. Only garments made of silk cotton develop "silk pearls" (clumps of silk floss); newly made clothes often have these pearls protruding through the fabric. Zhou Lüjing in *Qun Wu Qi Zhi* (Strange Manufactures of Various Things) states: Cotton-padded cloth clothes padded in midsummer do not have silk pearls, but those padded in autumn and winter do. Placing a few stalks of rush grass on the cotton prevents the formation of pearls. For medicinal use, the silk pearls from old clothes are taken because they have absorbed human qi for a long time. Silk pearls protruding from new clothes are useless. To treat gecko bites, mix with sesame oil and apply externally; it is miraculous.
To treat chancroid (specifically referring to a condition described as "scale hook sore"). This condition manifests as a sudden ulceration or hole near the anus within the first month of life in infants. *Sheng Ji Ku Hai* (Sea of Bitterness in Saving Lives): Use 2 qian of red velvet burned to ash, 5 fen pearl, 5 fen calomel, 2 qian catechu, 1 qian dragon's blood, and 1 qian frankincense. Grind into powder and apply dry to the lesion.
