（灌木）清肺凉血散热解毒
芙蓉花（专入肺。兼入肝）。为外科痈疽药也。凡清凉膏清露散铁箍散。即是此物。盖
此味辛
气平质滑。功专清肺凉血。散热止痛。消肿排脓。凡一切痈疽肿毒！无论花叶及根。皆可捣
研为末。调蜜涂四围。留中患处。干则频换。初起者即觉清凉。痛止肿消。已成者即脓出。
已溃者即易敛。或加赤小豆苍耳子同入为末。功效殊见。然必毒轻不重。用此方可。若大毒
阴毒。其势莫遏。则非轻小平剂所能治矣！此又不可不知也。
蓖麻子（专门作用于经络和各处孔窍）。味甘、辛，性热。其性味与巴豆颇为相似。它既有收敛牵引、拔出毒素的能力，又有开通窍道、通利身体的作用。据书籍记载，将其捣碎成膏贴敷于手臂肿痛处，一夜之间即可见效。（使用时可配合羊脂、麝香、鲮鲤甲等药材，煎制为按摩膏，每日多次涂抹。）子宫脱垂，将此药研成膏涂于头顶百会穴，子宫即可回纳。（或者将药仁捣烂贴敷于丹田穴也可以。）胞衣不下，将此药研成膏涂于脚心，胞衣即可排出。中风导致口眼歪斜，若偏向左侧则贴敷右手心，若偏向右侧则贴敷左手心，症状即可停止。至于牙关紧闭、鼻塞、耳聋、喉痹、舌体肿胀等症状，用油烟熏蒸即可开通。水气病导致的浮肿，服用研碎的蓖麻仁一顿即可消除。（体质强壮者最多只能服用五粒。）针刺误伤好肉，将药仁捣烂敷于患处即可拔出异物。瘰疬和恶疮，将药仁外敷立即痊愈。（李时珍说：鹈鹕油能引导药气进入体内，蓖麻油能拔出病气外出。）以上这些都属于外用而取得奇效的方法，但不宜内服。过去有人将汁液点在牲畜的舌根下，牲畜就不能进食；点入肛门内，就会因下血而死。并且传说服用蓖麻的人，一生不得再吃豆类食物，否则会导致腹胀而死。其毒性之大由此可见。需用盐水煮过，去皮，研磨取油使用。忌用铁器。
芙蓉花（专门作用于肺经，兼入肝经）。是治疗外科痈疽的药物。凡是清凉膏、清露散、铁箍散等方剂，都是以此物为主要成分。大概是因为此药味辛、气平、质地滑润，功效专于清肺凉血，散热止痛，消肿排脓。凡是一切痈疽肿毒，无论是花、叶还是根，都可以捣碎研末，用蜂蜜调和后涂在病灶四周，中间留出患处。干燥后频繁更换。初起时即感觉清凉，疼痛停止，肿胀消退；已经化脓的则脓液流出；已经溃破的则容易愈合。或者加入赤小豆、苍耳子一同研末，功效尤为显著。然而必须确认毒邪轻微且不严重，使用此方才合适。如果是大毒或阴毒，病情势不可挡，就不是这种轻平的药剂所能治疗的了！这一点又不可不知道。
(Venomous Herbs) Possess the power to astringe and draw out evil toxins, open orifices, and promote unobstructed flow.
Ricini Semen (Castor Bean) [Ricini Semen] (Specifically enters the meridians and various orifices). Sweet, pungent, and hot in nature. Its flavor and properties are quite similar to those of Crotonis Fructus (Castris Seed). It possesses the ability to contract and draw out toxins, as well as the power to open orifices and facilitate bodily functions. According to texts, when mashed into a paste and applied to swollen and painful arms, it yields results within one night. (It can be used together with Ovis Adipis (Sheep Fat), Moschus (Musk), and Manis Squama (Pangolin Scales) to decoct into a massage ointment, applied several times daily.) For uterine prolapse, applying this mashed paste to the Baihui point (GV20) on the vertex will cause the uterus to return to its normal position. (Alternatively, mashing the seed and applying it to the Dantian area is also effective.) For retained placenta, applying this mashed paste to the Yongquan point (KI1) on the sole of the foot will facilitate its expulsion. For facial paralysis causing deviation of the mouth and eye, apply to the palm of the right hand if the deviation is to the left, and to the palm of the left hand if the deviation is to the right; the condition will cease. For conditions such as trismus (lockjaw), nasal congestion, deafness, throat obstruction (hou bi), and tongue swelling, exposure to soot smoke will clear the obstructions. For edema caused by water retention, ingesting a dose of mashed Ricini Semen will eliminate the swelling immediately. (For robust individuals, do not exceed five seeds.) If accidentally pricked with a needle into healthy flesh, applying mashed Ricini Semen to the affected area will extract the foreign body. For scrofula (luo li) and malignant ulcers, external application of the seed leads to immediate healing. (Li Shizhen stated: Oil from the pelican can guide medicinal qi inward, while Ricinus oil can draw pathological qi outward.) All these applications achieve miraculous effects through external use, but they should not be ingested. In the past, it was recorded that placing the juice under the tongue of livestock rendered them unable to eat, and placing it inside the anus caused death due to hemorrhage. It is also said that anyone who consumes Ricini Semen must never consume beans for life; violating this rule causes fatal abdominal distension. This illustrates its toxicity. It should be boiled in salt water, peeled, ground, and the oil extracted. Iron vessels should be avoided during processing.
(Shrubs) Possess the functions of clearing the lungs, cooling blood, dissipating heat, and detoxifying.
Malvae Flower (Hibiscus Flower) [Malvae Flos] (Specifically enters the Lung meridian, and additionally enters the Liver meridian). It is a herb for treating surgical abscesses and carbuncles. Formulas such as Qingliang Gao (Cooling Paste), Qinglu San (Clear Dew Powder), and Tiegu San (Iron Hoop Powder) all utilize this material. Generally, this herb is pungent in flavor, neutral in nature, and smooth in texture. Its efficacy specializes in clearing the lungs and cooling blood, dissipating heat and relieving pain, reducing swelling and expelling pus. For any type of abscess, carbuncle, swelling, or toxin, whether using the flower, leaf, or root, it can be mashed and ground into powder. Mix with honey and apply around the periphery of the lesion, leaving the center exposed. Change frequently when dry. In the initial stage, it feels cool, stops pain, and reduces swelling. If suppuration has occurred, pus will drain. If ulcerated, healing occurs easily. Alternatively, adding Vigna angularis (Adzuki Bean) and Xanthii Fructus (Cocklebur Fruit) and grinding them together enhances the efficacy. However, this formula is only suitable when the toxin is mild and not severe. If dealing with potent toxins or yin-type toxins where the pathogenic force is unstoppable, this mild and gentle preparation cannot treat the condition. This distinction must be understood.
