乌龙膏：将木鳖子带壳烧至存性（保留药性），去壳；侧柏叶焙干；人中血（即乱发）烧成灰；青龙背、纸钱灰、飞罗面各一钱，全部研为细末。用好陈米醋调制成膏状，涂抹于疮口上，外用纸张贴敷。

治疗多年的阴阳各类癣症：《救生苦海》记载：取陈旧竹灯盏中被油浸透的部分，装入尖底瓶中，瓶口安装一个铁丝髻（发髻状的铁丝支架），在地上挖一个土坑，坑内放置一只大碗，将瓶子倒扣在碗上，瓶底朝上，周围用稻壳填满并燃烧，收集滴入碗中的油液涂抹患处，效果显著。《文堂验集》记载：治疗癣症，取多年使用的油浸竹灯挂一个，在火上烤出如胶状的油汁为佳品；另取五倍子去虫后炒制研为细末，将两味药混合一处，用陈醋在火上温热调和均匀后涂抹，非常有效。

Gong Tingxian recorded in *Huichun*: The greasy dirt on the surface of a pot lid is called "Qinglong Bei" (Green Dragon's Back), which can treat scrofula (tuberculous lymphadenitis) that has ulcerated and failed to heal for a long time. Use this substance added to "Wulong Gao" (Black Dragon Ointment) for treatment.
Wulong Gao: Burn *Miebanzi* (Strychnos nux-vomica seed) with shell until it retains its medicinal properties, remove the shell; roast *Cebaiye* (Platycladi Cacumen); burn *Renzhongxue* (i.e., disordered hair) into ash; use Qinglong Bei, paper money ash, and *Feiluomian* (fine sifted wheat flour), each one qian (approx. 3-5g). Grind all into fine powder. Mix well with aged rice vinegar to form a paste, apply to the sore, and cover externally with paper.
Today, sieves are known; some have bottoms woven with horsehair, others with silk gauze. For medicinal use, those with silk gauze bottoms are superior.
Treating overdue difficult labor: The collected emergency immortal prescription for overdue difficult labor states: Take one old sieve bottom, roll it into a tube, burn it inside a bowl, and administer to the parturient woman, allowing immediate delivery. If the delivered infant is covered with vernix caseosa (referred to as "Luo"), the efficacy is miraculous and verifiable.
Treating chronic Yin and Yang tinea (fungal skin infections): *Jiusheng Kuhai* records: Take an old bamboo lamp holder soaked with oil, place it in a pointed-bottom bottle. Install an iron wire bun-shaped stand at the bottle mouth. Dig a pit in the ground, place a large bowl inside, invert the bottle over the bowl with the base facing up, fill the surroundings with husk, and burn. Collect the oil dripping into the bowl and apply to the lesion; the effect is verified. *Wentang Yanji* records: To treat tinea, take an oil-soaked bamboo lamp hanger used for many years, heat it over fire until oil juice exudes like glue (this is preferred). Separately, stir-fry *Wubeizi* (Chinese gallnut) after removing insects and grind into powder. Mix the two ingredients together, warm with aged vinegar over fire, blend evenly, and apply; it is very effective.
Treating Lazi Toutou Chuang (a type of head ulcer occurring in winter): Zhang Ziqing's *Mifang Jiyan* records: Take one old bamboo lamp stand from a wine shop or restaurant that has been soaked with oil, break it into pieces, and pack it into a porcelain bottle. Cover the mouth with an old iron wire bun, invert it downwards. Place another empty porcelain bottle over the mouth of the lower bottle. Heat with fire so that the juice drips down. Collect the juice and apply to the sore; the effect is miraculous.
Treating Naolou (Nasal discharge/Ozena, similar to sinusitis): *Baicao Jing* records: Select a ten-year-old bamboo lamp wick frame; seek those from villages with oil stains; do not wash clean. Char them, bury in soil to preserve their nature, and grind finely. Use one or two qian each time, wrap in tofu skin, swallow with boiling water early in the morning. Continue taking until finished, and it will heal spontaneously.
Divine Efficacy Prescription for Changyong (Intestinal Abscess) and Duyong (Abdominal Abscess): *Bianyi Liangfang* states: Spasm/tightness of the right foot indicates Changyong; spasm/tightness of the left foot indicates Duyong. Take an old oil-stained bamboo lamp stand from decades ago, commonly known as "Shanfu". Take one, burn it until more than half done, do not extinguish with water but let it smolder into ash. Grind into fine powder. Take two or three qian washed down with aged Sanbai Jiu (Three White Liquor); recovery follows immediately. Wang Zhanzhu's *Bu Yao Liangfang* states: This medicine also treats Feiyong (Lung Abscess); it is an extremely divine prescription.
