皴痛皆起于手足，乃风寒气郁于皮毛，致血不荣于肌表，

六味地黄丸（见肺痈门）
田螺泡，多发生于手足部位，突然感觉如火烧般灼热，随即出现紫色、白色或黄色的水泡，这是脾经的风湿之邪攻注所致，不久后水泡会逐渐增大，伴有胀痛不适。用线针挑破以排出毒水，外用太乙膏覆盖。如果挑破后又复发，内服解毒泻脾汤即可痊愈。
解毒泻脾汤
解毒泻脾汤由牛蒡子、防风、苍术、山栀、石膏、甘草、黄芩等组成，木通和灯心草的效果值得推崇。
药物组成：防风、牛蒡子、山栀、石膏、黄芩、苍术、甘草、木通（各一钱）。
用水二钟，灯心草二十根，煎至八分满，根据病情在饭前或饭后服用。
皴痛均起于手足，是由于风寒之气郁结于皮毛，导致血液不能荣养肌表，所谓皮肤干枯则多疼痛，呈现出好像没有皮肤一样的状态，这就是皴痛产生的原因。将患处用葱汤浸泡清洗很久，随后涂抹润肌膏，注意保暖避免受风冷，即可自愈。另外，对于每逢冬季就发作的患者，必须在三伏天时晒捣烂的大蒜，间歇性擦拭三次，以后就不再发作。这叫做“寒因热治”，其中的道理非常明白。
阴虱又名八脚虫，是由肝、肾两经的浊气形成的。长了这种病被认为不吉利，用银杏散加津液调和后擦拭；内服六味地黄丸，每斤药中加入蜂蜜炒制的黄柏一两、芦荟五钱，以清除化生之源，治愈后不再复发。
银杏无忧散
银杏无忧散由麝香、水银、轻粉、杏仁组成，雄黄、野狼毒并芦荟，一经擦拭为何不露笑颜？
药物组成：水银（铅制）、杏仁（去皮，捣成膏状）、轻粉、雄黄、野狼毒、芦荟（各一钱），麝香（一分）。
除了水银和杏仁膏外，其余药物共同碾碎筛细，加入上述两种药再研磨均匀，先用土菖蒲煎汤清洗患处；用针挑去虱卵孔，随即用唾液调和药粉擦拭，使药气进入内部，治愈后不再生长。切忌食用牛肉、狗肉、鳖肉。
Tianluo Pao (River Snail Blister) mostly occurs on the hands and feet. It suddenly feels as if burning with fire, followed by the appearance of purple, white, or yellow blisters. This is caused by wind-dampness attacking and flooding the Spleen Meridian. The blisters will gradually enlarge in a short time, causing distending pain and discomfort. They should be punctured with a thread needle to drain the toxic fluid, and covered with Taiyi Gao (Great Sage Ointment). If they recur after being punctured, internal administration of Jiedu Xiapi Tang (Detoxification and Spleen-Draining Decoction) can cure it.
Jiedu Xiapi Tang (Detoxification and Spleen-Draining Decoction)
Jiedu Xiapi Tang consists of Niu Bang Zi (Arctii Fructus), Fang Feng (Saposhnikoviae Radix), Cang Zhu (Atractylodis Rhizoma), Shan Zhi (Gardeniae Fructus), Shi Gao (Gypsum Fibrosum), Gan Cao (Glycyrrhizae Radix et Rhizoma), Huang Qin (Scutellariae Radix), etc. Mu Tong (Akebiae Caulis) and Deng Xin Cao (Junci Medulla) are highly effective.
Ingredients: Fang Feng, Niu Bang Zi, Shan Zhi, Shi Gao, Huang Qin, Cang Zhu, Gan Cao, Mu Tong (each 1 qian).
Use two zhong of water and twenty roots of Deng Xin Cao (Junci Medulla). Decoct until one-eighth remains. Take according to the condition, either before or after meals.

Chansu Tiao (Toad Venom Strip) (See Ding Chuang Section)
Yuhong Gao (Jade Red Ointment) (See Swelling and Ulcer Section)
Cun Tong (Skin Fissure Pain) all originates on the hands and feet. It arises from wind-cold qi stagnating in the skin and hair follicles, causing blood to fail to nourish the muscle surface. As the saying goes, "when the skin is dry and withered, there is much pain," presenting a state similar to having no skin, which gives rise to Cun Tong. Soak and wash the affected area thoroughly in Cong Tang (Green Onion Decoction), then apply Runji Gao (Moisturizing Muscle Ointment). Keep warm and avoid wind and cold; it will heal spontaneously. Furthermore, for those who suffer recurrences every winter, grind garlic that has been sun-dried during the Sanfu (Dog Days) period, and apply it intermittently three times. It will not recur thereafter. This illustrates the principle of "treating cold with heat," which is quite clear.
Yinshi (Pubic Louse), also known as Bajiao Chong (Eight-Legged Bug), is formed from turbid qi of the Liver and Kidney meridians. Having this condition is considered inauspicious. Apply Yinxi San (Ginkgo Powder) mixed with saliva to the affected area. Internally, take Liuwei Dihuang Wan (Six-Ingredient Rehmannia Pill). For every jin (500g) of the pill, add one liang of Huang Bai (Phellodendri Cortex) stir-fried with honey and five qian of Lvhui (Aloe). This clears the source of transformation, ensuring no recurrence after cure.
Yinxing Wuyou San (Ginkgo Without-Worry Powder)
Yinxing Wuyou Powder contains Shexiang (Moschus), Shuiyin (Mercurius), Qingfen (Calomelas), Xingren (Armeniacae Semen Amarum), Xionghuang (Realgar), Yelangdu (Dichroa Radix), and Lvhui (Aloe). Why would one not smile after just one application?
Ingredients: Shuiyin (prepared with lead), Xingren (skin removed, pounded into paste), Qingfen, Xionghuang, Yelangdu, Lvhui (each 1 qian), Shexiang (1 fen).
Except for Shuiyin and Xingren paste, grind the remaining herbs finely and sift. Add the aforementioned two ingredients and grind uniformly. First, wash the area with Tu Changpu (Acori Tatarinowii Rhizoma) decoction. Use a needle to pick out the louse eggs/holes, then apply the powder mixed with saliva to allow the medicinal qi to penetrate. It will heal and not grow again. Strictly avoid consuming beef, dog meat, and softshell turtle meat.
