歌曰∶大凡恶毒瘀血成，不曾发散致痛疼，秘授奇方熏洗法，羌独荆防花木行，薄苏桃槐桑木叶，金银川草显威灵，
将药入锅同煎水，一熏洗后见太平。
（处方） 银花（三钱） 羌活 独活 川乌 草乌 防风 苍术 薄荷 苏叶（各二钱） 桑叶
桃叶 槐叶 樟叶（各一握）
（制法） 各药共同煎水备用。
（用法） 将煎好药水，乘热先熏后洗，洗后避风，功能祛风解毒，散结消肿，倘再加入黄
柏、川军、生地更妙。未成者，熏洗之后，将药渣捣涂患处，已成者，再加猪蹄汤淋洗，化腐生肌之功，效无其匹。
附方如次∶
白芷 川芎 藿香 木香 防风 甘草（各三钱） 火葱（一握）
上以米泔水六、七碗，将药投入其中，入锅煎浓，滤去药渣不用，以新棉蘸汤淋洗患处，汤冷再易热者，并随以手
轻擦患处四周，令疮内缩，脓随汤出，以尽为度。
万潜斋云∶熏洗有荡涤之功，涤洗则气血自然舒畅，其毒易于溃腐而无壅滞也。凡肿在四肢者 冼之，在腰
腹、脊背者淋之，在下部者浴之，俱以布帛或棉蘸洗，稍凉即易。轻者日洗一次，重者日夜洗二次，每日洗之，不可间
断。凡洗时，冬月要猛火以逼寒气，夏月要闭窗以避凉风，若不慎此，轻则有妨收口，重则恐变纯阴。夫洗药不一，如
初肿与将溃者，俱用“葱归 肿汤”洗；如阴症不起者，俱用“艾茸汤敷法”如溃后，俱用“猪蹄汤”烫洗。用猪蹄汤
者，以助肉之气而逐腐也。此洗涤之法，乃疡科之要药，方附于后，以备参考∶
一、葱归 肿汤
凡痈肿疮疡，初肿将溃之时，用此汤洗之，以疮内热痒为度。
葱头（七个） 当归 独活 白芷 甘草（各三钱）
上五味，以水三大碗，煎至汤醇，滤去渣，以绢帛蘸汤热洗，如稍凉再易之，洗时切忌风寒。
二、艾茸汤敷法
凡阴疮黑陷不痛者，皆可用之，以知痛则生，不知痛而出死血者死。并须内服大补回阳之剂以助之，方可转危为安。
硫黄（五钱） 雄黄（五钱） 艾茸（一握）
上以硫、雄二味为末，同艾水煎半日，水将干，取出艾捣烂，温敷患处，再煎再易，十余次为度。
三、猪蹄汤
凡痈疽诸毒流脓者，熬好洗之，以助肉气，消肿散风，脱腐止痛，去恶肉，活死肌，润疮口。如腐尽者，不必用之，
当以米泔水热洗之，令疮洁净，不可过洗，过洗则伤水，皮肤破烂，难生肌肉，不易敛口。
黄芩 甘草 当归 赤芍 白芷 蜂房 羌活（等分）
上七味，共为粗末，看证之大小，定药之多少。先将猪前蹄一双，用水六碗煮
之，蹄软为度，将汁滤清，吹去汁上油花，即用粗药末一两，投于汁中，再用微
火煎十数沸，滤去渣，候汤微温，即以方盘一个，于疮下靠身放定，随用软绢蘸
汤，淋洗疮上，并入孔内，轻手捺尽内脓，使败腐宿脓随汤而出，以净为度，再
以软帛叠七、八重，蘸汤勿令太干，覆于疮上，两手轻按片时，帛稍凉再换，如
此再按四、五次，可以流通血气，解毒、止痛、去瘀，洗讫，用绢帛拭干，即随症以应用之药贴之。
疮疡洗法，西医极端推崇，惟目标多在清洁杀菌，与中医洗涤之舒畅营卫、调和
气血者，目标各有不同，故中医洗涤之法，实应重视。
The song states: Generally, malignant toxins and blood stasis form together; if not dispersed in time, pain ensues. A secret miraculous method of fumigation and washing is revealed here. The herbs include Qianghuo (Notopterygii Rhizoma et Radix), Duhuo (Angelicae Pubescentis Radix), Jingjie (Schizonepetae Herba), Fangfeng (Saposhnikoviae Radix), Muxiang (Aucklandiae Radix), Ziye (Perillae Folium), Taoye (Persicae Folium), Huaiye (Sophorae Flavescentis Folium), Sangye (Mori Folium). Jinyinhua (Lonicerae Japonicae Flos), Yinzhu (Cinnabaris), and Caowu (Aconiti Radix) display their potent efficacy. Put the herbs into a pot and decoct with water. After one session of fumigation and washing, peace and stability are restored.
(Prescription) Jinyinhua (Lonicerae Japonicae Flos) (3 qian); Qianghuo (Notopterygii Rhizoma et Radix), Duhuo (Angelicae Pubescentis Radix), Chuanwu (Aconiti Radix Preparata), Caowu (Aconiti Kusnezoffii Radix), Fangfeng (Saposhnikoviae Radix), Cangzhu (Atractylodis Rhizoma), Bohe (Menthae Haplocalycis Herba), Ziye (Perillae Folium) (each 2 qian); Sangye (Mori Folium), Taoye (Persicae Folium), Huaiye (Sophorae Flavescentis Folium), Zhangye (Cinnamomi Ramulus Folium) (each one handful).
(Preparation) Decoct all herbs together in water for later use.
(Usage) Take the decocted liquid while hot. First fumigate the affected area, then wash it. Avoid wind after washing. This method has the functions of dispelling wind, resolving toxicity, dissipating nodules, and reducing swelling. If Huangbai (Phellodendri Cortex), Chuanjun (Rhei Radix et Rhizoma), and Shengdi (Rehmanniae Radix) are added, the effect is even better. For sores that have not yet suppurated, after fumigation and washing, mash the herb dregs and apply them to the lesion. For those that have already suppurated, add pig trotter soup for rinsing; its efficacy in resolving putrefaction and generating flesh is unparalleled.
Attached prescriptions are as follows:
Baizhi (Angelicae Dahuricae Radix), Chuanxiong (Chuanxiong Rhizoma), Huoxiang (Agastaches Herba), Muxiang (Aucklandiae Radix), Fangfeng (Saposhnikoviae Radix), Gancao (Glycyrrhizae Radix et Rhizoma) (each 3 qian); Huocong (Allii Fistulosi Bulbus) (one handful).
Take six or seven bowls of rice-washing water, put the herbs into it, and decoct in a pot until concentrated. Filter out the herb dregs. Dip new cotton in the soup and rinse/wash the affected area. Replace with hot soup when it cools down. Gently rub around the lesion with your hand to encourage the sore to retract inward, allowing pus to exit with the soup until completely drained.
Wan Qianzhai said: Fumigation and washing have the power of cleansing and scouring. Washing makes qi and blood naturally smooth, making it easier for toxins to ulcerate and rot without stagnation. For swellings on the four limbs, wash them; on the waist, abdomen, spine, and back, rinse them; on the lower body, bathe them. Use cloth or cotton to dip and wash, replacing immediately when slightly cool. Mild cases wash once daily; severe cases wash twice daily (morning and night). Wash daily without interruption. During washing in winter, use strong fire to drive out cold qi; in summer, close windows to avoid cool wind. If this is not observed carefully, mild cases may hinder wound closure, while severe cases may turn into pure yin syndromes. Regarding different washing herbs: for initial swelling and impending ulceration, use "Conggui Xiaozhong Tang" (Scallion and Angelica Anti-swelling Decoction); for yin syndromes that do not rise, use "Airong Tang Fu Fa" (Mugwort Down Poultice Method); after ulceration, use "Zhuti Tang" (Pig Trotter Soup) for scalding/washing. Pig trotter soup is used to assist muscle qi and expel putrefaction. This washing method is a key technique in surgery. The formulas are attached below for reference:
1. Conggui Xiaozhong Tang (Scallion and Angelica Anti-swelling Decoction)
For carbuncles, sores, and ulcers during initial swelling and impending ulceration, use this soup for washing until heat and itching are felt inside the sore.
Congtou (Allii Fistulosi Bulbus) (seven stalks); Danggui (Angelicae Sinensis Radix), Duhuo (Angelicae Pubescentis Radix), Baizhi (Angelicae Dahuricae Radix), Gancao (Glycyrrhizae Radix et Rhizoma) (each 3 qian).
Take these five herbs, add three large bowls of water, and decoct until the soup is rich. Filter out the dregs. Dip silk fabric in the hot soup and wash. Replace when slightly cool. Strictly avoid wind and cold during washing.
2. Airong Tang Fu Fa (Mugwort Down Poultice Method)
For yin sores that are black, depressed, and painless, this method can be used. Pain indicates vitality; painlessness with dark dead blood indicates death. Internal administration of major tonifying and yang-restoring agents is also required to assist and turn danger into safety.
Liuhuang (Sulfur) (5 qian); Xionghuang (Realgar) (5 qian); Airong (Artemisiae Argyi Folium prepared into moxa wool) (one handful).
Grind sulfur and realgar into powder. Decoct with mugwort water for half a day. When water is nearly dry, take out the mugwort, mash it, and apply warm to the lesion. Re-decoct and replace. Ten to twelve times is the limit.
3. Zhuti Tang (Pig Trotter Soup)
For carbuncles, furuncles, and various toxic sores discharging pus, boil this soup well for washing. It assists muscle qi, reduces swelling, disperses wind, removes putrefaction and pain, eliminates foul flesh, revitalizes dead tissue, and moistens the sore opening. If putrefaction is already gone, this method is unnecessary; instead, wash with hot rice-washing water to keep the sore clean. Do not over-wash, as excessive washing damages fluids, causes skin breakdown, hinders muscle growth, and delays healing.
Huangqin (Scutellariae Radix), Gancao (Glycyrrhizae Radix et Rhizoma), Danggui (Angelicae Sinensis Radix), Chishao (Paeoniae Radix Rubra), Baizhi (Angelicae Dahuricae Radix), Fengfang (Apis Nests), Qianghuo (Notopterygii Rhizoma et Radix) (equal parts).
Grind these seven herbs into coarse powder. Determine the amount based on the size of the condition. First, boil one pair of pig front trotters in six bowls of water until soft. Filter the broth, clear it, and blow away the oil film. Add one liang of the coarse herb powder to the broth. Simmer gently for ten to fifteen boils. Filter out the dregs. Wait until the soup is slightly warm. Place a square basin under the sore near the body. Dip soft silk in the soup, pour/rinse over the sore, and into any openings. Gently press to drain internal pus, letting foul and old pus exit with the soup until clean. Fold soft cloth seven or eight layers, dip in soup (not too dry), cover the sore, and press gently with both hands for a moment. Replace when the cloth cools. Repeat pressing four or five times to promote qi and blood circulation, resolve toxicity, relieve pain, and remove stasis. After washing, wipe dry with silk, and apply appropriate medicaments according to the syndrome.
Western medicine highly推崇 (advocates) the washing method for sores and ulcers, but its goal is mostly cleaning and sterilization. In contrast, the Chinese medicine washing method aims to soothe Ying and Wei (nutritive and defensive qi) and harmonize qi and blood. Since the goals differ, the Chinese medicine washing method deserves serious attention.
