后天获得的各类毒邪容易辨别，先天禀受的毒邪则难以明确诊断，轻者表现为疮疡发作。起初类似风疹瘾块，逐渐形成细小的瘰疬，一旦搔抓发痒，随即渗出湿液，蔓延如癣疾，从头至全身，上下随感受而发作，这种疮疡内有“虫”，所以名为“虫胞”，意指其源于胞胎之中。这总是由于湿与火相互搏结，血热毒盛，腠理（皮肤纹理及汗孔）更加开泄，淫邪毒气愈发炽盛；瘙痒多因气虚所致，疼痛多因血虚所致，病症归属于腑证。若病程迁延日久，气血虚弱，则因热邪而起，又因热邪乘虚内攻脏腑。治疗应以托里解毒为最佳方法。然而，如果痊愈时却在颈部结聚，这是六阳经诸毒上冲，火毒炎上的征象。如果初起便在颈部发作，则是胎毒壅盛，向上侵犯阳位。如头发稀疏、面部有白屑，久治不愈的，即称为秃疮。也有年长后患脑疳，出现白秃且不长头发的，这是因为足少阴肾经其华在发，因疳积导致热血耗损，气血减少，不能滋养头发所致。有的疮疡收束在四肢，是日久脾虚，湿毒侵袭所致。所谓惊疮，惊本身并无实物，是因为跌蹉损伤了血气，在脏则为积聚，在腑则流溢于皮肤，从而形成疮疡。练银疮，是指眉间生疮，这是肺热的表现。风疮也是发遍全身，形态很小，俗称疥疮。虫窠疮，是指疮窠内有虫，如细虮子之类。各种疮疡的治疗方法：如果痛痒难忍，以及性情急躁、面色黑而血热者，宜用苦寒药物，如黄芩、黄连、苦参之类。身体肥胖的人，宜以祛风、燥湿、清火为主。如在久病之后，湿邪蒸腾外达者，只需进行补益托毒，切勿多洗浴或涂抹收敛药物，以免导致毒邪内攻。虽然各种疮疡都属于心火，但常用寒凉药物时，需注意热则行散，寒则凝滞，凝滞则毒邪反而停滞难以痊愈，所以不如透肌解毒、和血养阴的方法，这样风火平息，燥痒消除，且气血充盛坚固，各种毒邪便不能为害了。如果在痘疹之后生疮，是余毒未尽，也宜化解毒邪、调和血液。如果在出疮前发生惊厥，或者出疮后发生惊厥，都是因为疮疡引起的，都应以调理疮疡为主。至于一切胎毒，都宜凉血、清热解毒，使毒邪发散于体外，切勿轻易从外部治疗，以致热毒内攻，最终造成无法挽救的后果，因为小儿脏腑娇嫩，病邪易入难出。如果到疮色焦枯，肚腹青黑，生疮而无脓汁，或者遍体都是疮毒，发于胁肋部或在少腹部，或在顶门肿起的，都属于不治之症。
Use *Prunella vulgaris* (Xiakucao, 夏枯草), in any quantity. Boil it in a pot until soft and rotten, remove the dregs, extract the juice, and boil it down into an ointment for external application.
Acquired toxins from postnatal life are easy to identify, whereas congenital toxins inherited from prenatal life are difficult to clarify. In mild cases, they manifest as sores. Initially resembling urticaria (wind hives), they gradually develop into small scrofula (lymphatic tuberculosis). Once scratched and itchy, they exude dampness and spread like tinea (ringworm), starting from the head and covering the whole body, appearing up and down according to the pathogenic influence. These sores contain "worms," hence named "Chongbao" (Insect Nest), implying their origin from the fetal womb. This is always due to the mutual aggression of dampness and fire, with excessive blood heat and toxicity. As the couli (pores and skin texture) become more open, the pernicious toxins become even more rampant. Itching is often attributed to Qi deficiency, while pain is attributed to Blood deficiency; the symptoms belong to the Fu organs. If the condition persists for a long time, leading to Qi and Blood deficiency, the pathology arises from heat and further invades the interior due to the deficiency attacking via heat. The treatment should prioritize supporting the interior and resolving toxicity. However, if nodules form on the neck during recovery, this indicates the upward rush of various toxins from the Six Yang meridians, a sign of flaming fire toxins rising. If sores appear on the neck from the onset, it signifies that congenital toxins are abundant and invading the Yang regions from above. If hair is sparse and there are white scales on the face, persisting for a long time without healing, it is called "Tuchuang" (Bald Sore). There are also cases where adults suffer from "Naogan" (Brain Chancre), presenting with bald patches where hair does not grow. This is because the Kidney meridian of Foot-Shaoyin manifests in the hair; due to Chancre-heat damaging the blood and Qi, the reduced Qi and Blood fail to nourish the hair. Sores confined to the limbs indicate long-standing Spleen deficiency and invasion by damp-toxins. The so-called "Jingchuang" (Fright Sore) implies that fright itself has no physical substance; it results from trauma disrupting Qi and Blood. In the Zang organs, it forms accumulations; in the Fu organs, it overflows into the skin, forming sores. "Lianyin Chuang" (Silver Polishing Sore) refers to sores arising between the eyebrows, indicating Lung heat. "Fengchuang" (Wind Sore) also spreads over the whole body but is very small, commonly known as Scabies ("Jie"). "Chongke Chuang" (Insect Hive Sore) contains worms within the hive, such as fine nits. Regarding the treatment of various sores: if pain and itching are unbearable, or if the patient is irritable, dark-faced, and has blood heat, bitter-cold herbs should be used, such as *Scutellariae Radix* (Huangqin, 黄芩), *Coptidis Rhizoma* (Huanglian, 黄连), and *Sophorae Flavescentis Radix* (Kushen, 苦参). For obese individuals, the main approach should be dispelling wind, drying dampness, and clearing fire. In cases following chronic illness, where dampness steams outward, only tonification and support are needed; one must avoid frequent bathing or applying astringent topical treatments, which might cause toxins to invade inward. Although all sores are related to Heart fire, when using cold-cooling methods, one must note that heat promotes circulation while cold causes stagnation. Stagnation leads to toxin retention and difficulty in recovery. Therefore, it is better to use methods that penetrate the muscle layer to resolve toxicity, harmonize Blood, and nourish Yin. This extinguishes wind-fire, removes dryness and itching, and ensures sufficient and solid Qi and Blood, preventing various toxins from causing harm. If sores appear after smallpox or chickenpox, it is due to residual toxins; detoxification and blood harmonization are appropriate. If convulsions occur before or after the appearance of sores, they are caused by the sores themselves; the primary treatment should focus on managing the sores. For all congenital toxins, cooling Blood, resolving toxicity, and clearing heat are indicated to disperse toxins outward. One must not lightly resort to external treatments alone, which could cause heat-toxins to invade inward, leading to fatal outcomes, especially since children's Zang-Fu organs are delicate, making pathogens easy to enter but hard to expel. If the sores turn scorched and dry, the abdomen turns blue-black, sores produce no pus, or if the entire body is covered with toxic sores swelling on the flanks, lower abdomen, or the fontanelle, these are all incurable conditions.
