小儿暑月头额生疖，亦可用。
生水蛭（一名马蟥蜞。取数枚，置碗水中，用讫纵之。冬月蛰于积水边，或田塍水道边
，掘土取之。）
上用薄纸一片，剪丸如疮大；仍看疮脓头有几个，其纸对脓头作小眼，搭在疮上。将水
蛭着在纸眼处，每一脓头用一水蛭，要得先咂去脓，其痛立止。如无脓头，即以手指按之，
觉最热处是也。或用茶末，以水调涂疮上，看先干处即点记，如不能辨，即着在中间。如脓
头只一个，而赤晕稍大，即近中处加用水蛭。如脓血咂尽，痛定肿退，可用膏药贴之。

觉
衣被皆湿，以烛视之，乃疮口自出血也。（水蛭咂尽恶血，不曾贴膏药，身暖，好血随路而
出。）急令取池中藕，将藕节处泥抹疮口，其血立止。按本草云，水蛭攻痈肿毒肿，取十余
枚病处，取皮皱肉白，无不瘥。冬月中无水蛭虫，地中掘取，暖水中养之，令动。先洗去
人皮咸，以竹筒盛蛭，缀之，须臾便咬，血满自脱，更用饥者。（张仲钦运使传云，绍兴壬
申岁，沿檄至汀，亲目其事。）

Freshwater leeches (also known as *Ma Huang Qi*. Take several, place them in a bowl of water, and release them after use. In winter, they hibernate near stagnant water or field ditches; dig up the soil to retrieve them.)
Cut a piece of thin paper into a circle the size of the sore; observe how many pus heads are present, and cut small holes in the paper corresponding to each pus head. Place the paper over the sore. Position the freshwater leeches on the holes in the paper, using one leech per pus head, to first suck out the pus, which will immediately stop the pain. If there is no obvious pus head, press with fingers; the hottest spot indicates the lesion. Alternatively, mix tea powder with water and apply it to the sore; mark where it dries first. If indistinguishable, apply to the center. If there is only one pus head but a slightly larger area of redness, add more leeches closer to the center. Once the pus and blood are fully sucked out, pain subsides, and swelling recedes, apply a medicated plaster.
During the Shaoxing era of Emperor Gaozong's reign, Huang Wu, the Prefect of Tingzhou, developed a carbuncle between his shoulder and back. Medical treatments were ineffective, but treatment with freshwater leeches yielded immediate results. Because he slept under a slightly warm quilt, he woke up to find his clothes and bedding soaked. Upon inspection by candlelight, it was found that the wound had spontaneously bled. (This occurred because the leeches had sucked out all the foul blood; without the application of a plaster and due to body warmth, healthy blood flowed out along the path.) He urgently ordered lotus roots from the pond to be fetched, and mud from the lotus root joints was applied to the wound, stopping the bleeding immediately. According to the *Bencao* (Materia Medica), freshwater leeches attack and treat carbuncles and toxic swellings. Placing about ten leeches on the affected area until the skin wrinkles and the flesh turns white ensures recovery. In winter, when freshwater leeches are not available in water, they can be dug from the ground and kept in warm water to stimulate activity. First, wash away the saltiness from human skin, store the leeches in a bamboo tube, suspend them; within moments, they will bite and suck blood, detaching themselves when full. Use hungry leeches subsequently. (Zhang Zhongqin, the Transport Commissioner, recounted: In the Ren-Shen year of Shaoxing, while inspecting Tingzhou, I witnessed this personally.)
