其色红而作痛者是。用男子尿桶中白霜敷上，立刻消凉止痛。干则再敷。或照上瘭疽各
方治之亦可。
杉木屑，煎水洗；用活螃蟹黄、滑石和蜜调敷，甚效。此林屋山人方也。有漆之处，先
嚼川椒敷鼻孔，可免漆疮。
又方∶贯众，焙枯研末，香油调敷。或用韭菜捣汁敷。或用白羊乳搽之均效。
又方∶白果树叶煎水洗，立刻消，三次全愈。或用新荷叶煎水洗，亦极神效。
又方∶活螃蟹，捶汁摘入，使毒水流出自愈。如已肿烂，取生蟹黄涂之，其烂更甚，数
日即愈。若再不效，用生大黄三钱，枳壳二钱，水煎服，二剂腹泻而愈。不泻加芒硝二钱，
以泻为度。缘漆疮火盛则重，非泻不能愈也。
凡癣内有虫，治好复发，非药不灵，虫未尽也。发后再治，无不愈矣。头面生癣，如入
眼内即成大麻风矣。宜急治之，新鲜皂角刺一二斤，捣烂，熬至将成膏时，加好醋熬稠，将
癣剃破敷之。日剃日敷，自有毒水流出，流尽再敷十日。虽数十年阴顽恶癣，无不断根。此
林屋山人屡试神方。
又方∶斑蝥五分，生半夏末一钱。鸡蛋油调搽数次，则痛必愈。再发再搽，虽多年恶癣
，无不断根。取鸡蛋油法见痈毒诸方。

那些颜色发红且伴有疼痛症状的，属于此类。使用男子尿桶内壁结成的白霜敷于患处，能立刻使患处清凉并缓解疼痛。若药膏变干，则再次涂抹。或者参照治疗瘭疽的各个方剂进行治疗也可以。
用杉木屑煎水清洗；或者取活螃蟹黄与滑石粉混合蜂蜜调匀后外敷，效果极佳。这是林屋山人的方子。在有漆树的地方，事先咀嚼川椒敷在鼻孔内，可以预防漆疮。
另一个方子：将贯众焙至枯焦后研成粉末，用香油调和后外敷。或者用韭菜捣汁外敷。或者用白羊乳擦拭，均有效。
又一个方子：用白果树叶煎水清洗，能立刻消退，三次即可痊愈。或者用新鲜荷叶煎水清洗，也极为神效。
又一个方子：取活螃蟹，捣碎取汁，滴入患处，使毒水流出，即可自愈。如果已经肿胀溃烂，取生蟹黄涂抹，虽然溃烂处可能会暂时加重，但数日即可痊愈。如果上述方法仍无效，用生大黄三钱、枳壳二钱，加水煎服，服用两剂后出现腹泻症状即可痊愈。如果不腹泻，则加芒硝二钱，以出现腹泻为度。因为漆疮若火毒炽盛则病情严重，非通过泻下不能痊愈。
凡是癣症内部有虫，治愈后复发，并非药物不灵验，而是虫子未除尽。发作后再进行治疗，没有不能痊愈的。头面部生癣，如果进入眼睛就会变成大麻风。应当紧急治疗，取新鲜皂角刺一二斤，捣烂，熬制到即将成膏状时，加入好醋继续熬至浓稠，将癣皮剃破后敷上。每天剃刮并每天敷药，自有毒水流出，流尽后再继续敷药十天。即使是患了几十年的阴寒顽固恶癣，也能断根。这是林屋山人多次验证的神方。
又一个方子：斑蝥五分，生半夏末一钱。用鸡蛋油调和涂抹数次，疼痛必然痊愈。再次发作再涂抹，即使是多年的恶癣，也能断根。取鸡蛋油的方法见痈毒诸方。
又一个方子：青矾炒制成块状后研成细末，加入猪胆汁调和后再炒再研，取老姜一块切开，蘸取药粉擦拭，剧烈疼痛后即可痊愈。再次发作再擦拭，即使是多年的顽癣，也可除根。
又一个方子：取大蜂窠一个，用白矾末填满孔洞，用火烤至白矾融化为止，研磨均匀，将癣抓破，用牙硝水调和后涂抹一两次，疼痛则必然痊愈。再次发作再涂抹，必能除根。
又一个方子：将荔枝核磨醋，将癣抓破后擦拭，虽然会痛但不必担心，数日即可痊愈。再次发作再擦拭可断根。
又一个方子：用新棉花扯成如纸般薄的一层，根据癣的面积大小将棉花铺贴在上面，用火点燃棉花，顷刻间燃尽，当即止痒，而且并不会造成焦灼涌出，不需要用药，极其简易、极其有效，只需一次即可痊愈。次年若再发，照此法治疗一次即可断根。
又一个方子：用珠兰花叶，经常擦拭，半个月即可断根。
Those presenting with red coloration and pain are of this type. Apply the white frost collected from the interior walls of a man's urine bucket to the affected area; it will immediately cool the area and relieve pain. Reapply when the dressing dries. Alternatively, one may treat it according to the various formulas for treating *biao ju* (acute infectious skin disease).
Wash with water decocted from fir wood shavings; or mix yellow bile from a living crab with talcum powder and honey to make a paste for topical application, which is highly effective. This is a formula by Linwu Shanshan. To prevent lacquer dermatitis in areas where lacquer trees grow, chew Sichuan pepper (*Chuanjiao*) beforehand and apply it to the nostrils.
Another formula: Roast *Guanzhong* (Cyrtomium fortunei) until charred, grind into powder, and mix with sesame oil for topical application. Alternatively, apply juice extracted from crushed Chinese chives (*Jiucai*). Or wipe with goat milk; all are effective.
Yet another formula: Wash with water decocted from leaves of the white fruit tree (*Baiguo*), which causes immediate resolution; complete recovery occurs after three applications. Alternatively, wash with water decocted from fresh lotus leaves, which is also extremely effective.
Yet another formula: Crush a living crab to extract its juice and drip it into the lesion to allow toxic fluids to drain out, leading to self-healing. If the area is already swollen and ulcerated, apply raw crab yellow; although the ulceration may temporarily worsen, it heals within a few days. If these methods remain ineffective, administer orally a decoction of 3 qian of raw *Dahuang* (Rhubarb Rhizome) and 2 qian of *Zhiqiao* (Aurantium Fructus), taken over two doses. Recovery occurs upon experiencing diarrhea. If diarrhea does not occur, add 2 qian of *Mangxiao* (Natrii Sulfas) and continue until diarrhea is induced. This is because severe cases of lacquer dermatitis involve excessive fire-toxin, which cannot be cured without purgation.
In cases where tinea involves internal parasites, recurrence after treatment indicates that the herbs are not ineffective but rather that the parasites have not been fully eradicated. Treating again upon recurrence ensures cure. Tinea on the head and face that enters the eyes can develop into leprosy (*Da mafeng*); urgent treatment is required. Take 1–2 jin of fresh *Zaojiaoci* (Gleditsiae Sinensis Spina), crush them, and decoct until nearly forming a paste. Add good vinegar and continue decocting until thick. Shave the affected tinea skin and apply the paste. Shave and apply daily; toxic fluid will naturally drain out. Continue applying for ten days after drainage ceases. Even chronic, stubborn, malignant tinea lasting decades can be eradicated. This is a divine formula repeatedly verified by Linwu Shanshan.
Another formula: Mix 5 fen of *Banmao* (Mylabris) with 1 qian of raw *Banxia* (Pinelliae Rhizoma) powder. Apply several times mixed with egg yolk oil; pain will surely resolve. Reapply upon recurrence; even long-standing malignant tinea can be eradicated. The method for obtaining egg yolk oil is found in the formulas for carbuncles and toxins.
Another formula: Calcine *Qingfan* (Melanteritum) until it forms lumps, then grind into fine powder. Mix with pig bile, calcine again, and grind again. Cut a piece of old ginger, dip it into the powder, and rub it onto the lesion; severe pain will cease and healing will follow. Reapply upon recurrence; even long-standing stubborn tinea can be eradicated.
Another formula: Take one large beehive, fill the holes with *Baijian* (Alumen) powder, and heat until the alum melts. Grind uniformly. Scratch the tinea open and apply a mixture of *Yaxiao* (Natrii Nitras) and water once or twice; pain will surely cease and healing will follow. Reapply upon recurrence; eradication is certain.
Another formula: Grind *Lizhihe* (Litchi Seed) with vinegar. Scratch the tinea open and rub with the mixture. Although painful, do not fear it; recovery occurs within a few days. Reapplication upon recurrence ensures eradication.
Another formula: Pull fresh cotton wool into a layer as thin as paper. Place the cotton over the tinea area according to its size. Ignite the cotton with fire; it burns up instantly, stopping itching immediately without causing burning or suppuration. No other medication is needed. It is extremely simple and effective, requiring only one application for complete cure. If it recurs the following year, repeat the treatment once to eradicate it.
Another formula: Rub *Zhulanhua ye* (Magnolia Flower Leaves) frequently; eradication occurs within half a month.
