今之膏药古称薄贴。自退毒消肿，以及既溃之后提脓化腐、搜毒生肌，无不惟薄贴是尚
。虽另掺末药，各有分寸，而膏药本以药物合成，亦必自有分别，不可温凉寒热混为一陶。
市肆中物油质不净，甚且助其化腐，固不可概用。而疡医家自制薄贴，亦复只有一种，其意
以为但当于末药中分别疗治，已是各合其宜，则薄贴一层，亦可不复注意。黄墙朱氏备有数

现在的膏药在古代被称为“薄贴”。无论是退毒消肿，还是溃破之后提脓化腐、搜毒生肌，都极其推崇薄贴。虽然另外掺入散剂药物，各有分寸，但膏药本身是由药物合成的，也必然有各自的分别，不能将温、凉、寒、热的药性混为一炉熬制。市面上售卖的膏药，其油质不纯净，甚至可能助长腐烂，确实不能一概使用。而外科医生自制的薄贴，往往也只有一种，他们的想法是认为只要在散剂药物中分别进行治疗，就已经各自适宜了，那么薄贴这一层，也就不再注意。黄墙朱氏备有多种薄贴，分别治疗寒证和热证，这实在是非常不可缺少的。我接触新式学问后，常认为中医旧法过于粘腻，如果腐烂已经严重，油纸薄贴不能吸收脓水，确实不够完善，不如新法使用脱脂棉纱更能收湿。我曾尝试采用这种方法，并另外使用自制的散剂药物分别施用。虽然这种做法不中不西、亦中亦西，世俗之人见到，难免会在旁边窃笑。但我自认为这是执守两端而取其中道，颇为可取。这里一并提及，有慧眼的人应当不会以“骑墙派”这三个字来妄加非议。
治疗阳证疮疡红肿以及溃破后脓水未净的情况，各根据适用的散剂药物，掺入后使用。
大生地（切薄片一斤） 全当归（八两） 羌活 黄芩 川柏（各三两） 玄参 苦参 甘草（各四两） 白芷 赤芍（各二两） 锦纹大黄（六两） 木鳖子（一两）
以上各药材切成片状，用真芝麻油二十斤，在大锅中煮沸，先放入生地、木鳖子熬煮二十分钟，再放入其他药物，等到药材焦枯离火，用细布滤去药渣，另换干净的锅用文火熬沸，然后加入筛细的广丹、筛细的定粉（即铅粉）各一斤，离火，预先研好的血竭、腰黄、轻粉、银珠各一两五钱（最好再加麝香、梅片不拘多少）一同调匀。预先准备大缸注入水，趁膏药热时倒入水中，浸泡到半凉时，就在水中分成若干团，大约每团一斤左右。另放入瓮中的清水里养护，密封备用。日久不坏，用油纸摊开贴敷。
【方解】 此薄贴能消除阳证疮疡肿块，清热解毒，无论已溃破或未溃破均可通用。溃破后并口。疮疡小疖即贴此膏，不必另外加掺药，也没有无效的。只有溃烂腐肉巨大者，油纸摊膏不吸脓水，宜用西法棉纱、棉花、锌养油膏，再加提脓化腐的散剂为佳。直到新肌已满脓水不多，覆盖此膏就容易收口。
The plaster of today was anciently called "Bo Tie" (Thin Paste). Whether for reducing toxicity and swelling, or for extracting pus and eliminating putrefaction, searching out toxins, and generating flesh after ulceration, all highly value the Bo Tie. Although additional powdered medicines are applied separately with precise dosages, the plaster itself is synthesized from medicinal materials and must have its own distinctions; one cannot mix warm, cool, cold, and hot properties into a single cauldron. The oils used in market-bought plasters are often impure and may even promote putrefaction, so they certainly cannot be used indiscriminately. However, self-made Bo Ties by surgeons often consist of only one type, based on the idea that treating via powdered medicines alone is sufficient and appropriate, thus paying no further attention to the plaster layer itself. Zhu of Huangqiang prepared several types of Bo Ties to treat cold and heat syndromes respectively, which is truly indispensable. Having studied new learning, I often consider traditional Chinese medicine methods too sticky and greasy; if putrefaction is severe, oil-paper plasters cannot absorb pus and water, which is far from perfect. It is better to use the new method of applying de-fatted cotton gauze for better moisture absorption. I have occasionally adopted this method while separately applying my own prepared powdered medicines. Although this approach is neither purely Chinese nor Western, but both, laypeople might sneer at it. Yet I believe holding to both extremes and using the middle path is quite commendable. This is mentioned here as well; those with discerning eyes should not criticize it as being a "fence-sitter."
For treating Yang-type swellings with redness and swelling, and cases where pus remains after ulceration, apply the respective applicable powdered medicines onto the plaster before use.
*Sheng Di Huang* (Rehmanniae Radix Praeparata, sliced thin, 1 jin) *Dang Gui* (Angelicae Sinensis Radix, 8 liang) *Qiang Huo* (Notopterygii Rhizoma et Radix) *Huang Qin* (Scutellariae Radix) *Chuan Bai* (Phellodendri Chinensis Cortex, each 3 liang) *Xuan Shen* (Scrophulariae Radix) *Ku Shen* (Sophorae Flavescentis Radix) *Gan Cao* (Glycyrrhizae Radix et Rhizoma, each 4 liang) *Bai Zhi* (Angelicae Dahuricae Radix) *Chi Shao* (Paeoniae Radix Rubra, each 2 liang) *Jin Wen Da Huang* (Rhei Radix et Rhizoma, 6 liang) *Mu Bie Zi* (Strychni Semen, 1 liang)
Cut all the above ingredients into slices. Use 20 jin of pure sesame oil, boil in a large pot. First add *Sheng Di Huang* and *Mu Bie Zi*, simmer for 20 minutes, then add the other herbs. When the herbs become scorched and dry, remove from fire. Filter the dregs cleanly through fine cloth. Transfer to another clean pot, bring to a boil over gentle fire. Then add finely sifted Guang Dan (Lead Oxide) and finely sifted Ding Fen (Litharge/Lead Carbonate, i.e., Qian Fen) each 1 jin. Remove from fire. Pre-grind *Xue Jie* (Dragon's Blood), *Yao Huang* (Realgar), *Qing Fen* (Calomel), and *Yin Zhu* (Cinnabar) each 1.5 liang (best to add She Xiang (Musk) and Bing Pian (Borneol) in any amount) and mix evenly. Prepare a large vat filled with water. While the plaster is hot, pour it into the water. Soak until half-cooled, then divide into several balls in the water, approximately 1 jin per ball. Place into a jar filled with clear water for nourishment/sealing, seal tightly for later use. It does not spoil even after long periods. Spread on oil paper and apply.
[Formula Analysis] This Bo Tie can eliminate Yang-type swelling masses, clear heat and detoxify, and is universally applicable whether ulcerated or not. For small boils and ulcers, simply applying this plaster without additional powders is effective. Only in cases of massive ulceration and putrefaction, where oil-paper plasters cannot absorb pus, is it advisable to use Western-style cotton gauze, cotton, zinc oxide ointment, combined with pus-extracting and putrefaction-eliminating powders. Once new tissue has fully grown and pus is scant, covering with this plaster facilitates wound closure.
