疔疮，属于火毒证候。其特点是形态小而根部深，发病部位不固定。如火焰疔多生于嘴唇、口腔及手掌手指关节之间，初起时呈现一点红黄色的小疱，疼痛并伴有麻木和瘙痒感，这是心经的毒火所致。紫焰疔多生于筋骨之间，初起呈紫色，次日破溃流出血水，这是肝经的毒火所致。黄鼓疔多生于颧骨、面颊和眼睑，局部发黄、麻木瘙痒，这是脾经的毒火所致。白刃疔多生于鼻孔和双手，顶部发白且坚硬，根部突起，伴有痒痛，容易腐烂且毒邪内陷，严重会导致腮部受损，这是肺经的毒火所致。黑疔多生于耳窍、牙缝以及胸腹腰间，出现黑色斑点或紫色瘀斑，质地顽固坚硬如钉子，疼痛彻骨，严重时手足发紫，患处柔软下陷且孔洞深，这是肾经的毒火所致。又有红丝疔，发于手掌及骨节之间，初起为小疮，逐渐蔓延出红色血丝，向上攻至手臂，急需用针在红丝尽头处刺破出血，随即回到初起的小疮上挑破，使用蟾酥条外敷。又有暗疔，先在腋下出现坚硬肿胀且无脓头，随后肿及阴囊和睾丸，局部发热疼痛。又有内疔，先发寒热症状，腹痛数日后，突然肿起一块硬块。对于暗疔和内疔，不使用挑破法，而是服用蟾酥丸三丸，用三寸长的葱白包裹药丸，以黄酒送服，盖被卧床促使出汗。若短时间内不出汗，说明是毒热阻滞结聚，仍需用发汗和泻下的方法，使毒热随之解除。又有羊毛疔，身体出现寒热，前胸后背有类似疹形的红点，先将紫黑色的斑点用衣针挑出，状如羊毛，前后共挑数处，立即出汗即可痊愈。
（有的因竹木刺戳伤，或瓷铁锋利物擦伤，溃烂后疼痛剧烈，时常流出污秽之水，肉色紫暗，身体发冷发热，这原本是由于阴虚所致，治疗应以酸甘之品收敛阴液、补益虚损，或用咸苦之品制约火邪、泄除热毒，宜参考溃疡门的治法。如果误作疔疮治疗，病情蔓延无效，反而造成大害。）
Ding (Furuncle/Carbuncle with deep root). It is a fire-toxin syndrome. Its characteristics are a small surface shape but a deep root, and it can arise anywhere. For example, Huoyan Ding (Flame Ding) often occurs on the lips, mouth, and interphalangeal joints of the hands. Initially, it presents as a small red-yellow papule, accompanied by pain, numbness, and itching; this is due to toxic fire in the Heart Meridian (Heart Channel). Ziyan Ding (Purple Flame Ding) often arises between muscles and bones. Initially purple, it breaks down the next day bleeding serosanguinous fluid; this is due to toxic fire in the Liver Meridian (Liver Channel). Huanggu Ding (Yellow Drum Ding) often occurs on the zygomatic cheeks and eyelids, presenting with yellow discoloration, numbness, and itching; this is due to toxic fire in the Spleen Meridian (Spleen Channel). Bairun Ding (White Blade Ding) often occurs around the nostrils and both hands. The top is white and hard, the root is protruding, with itching and pain; it easily suppurates and sinks inward. In severe cases, it damages the cheeks; this is due to toxic fire in the Lung Meridian (Lung Channel). Hei Ding (Black Ding) often occurs in the ear canals, dental gaps, chest, abdomen, and waist. It presents with black spots or purple macules, stubbornly hard like a nail, with pain penetrating to the bone marrow. In severe cases, the extremities turn purple, the lesion becomes soft and sunken with a deep pore; this is due to toxic fire in the Kidney Meridian (Kidney Channel). There is also Hongsi Ding (Red Thread Ding), which develops on the palms and between joints. It begins as a small sore, gradually spreading red threads upward to the forearm. Urgently, use a needle to pricking and bleed at the end of the red thread, then return to the initial sore to puncture it, and apply Chansu Strip (Toad Venom Strip). There is also An Ding (Hidden Ding), where hardness and swelling first appear in the axilla without a head, subsequently swelling to the scrotum and testes, with local heat and pain. There is also Nei Ding (Internal Ding), which initially presents with chills and fever, abdominal pain for several days, followed by a sudden lump swelling. For An Ding and Nei Ding, the puncturing method is not used. Instead, administer three pills of Chansu Wan (Toad Venom Pill), wrapped in a 3-cun-long Scallion White (Congbai, Allii Fistulosae Bulbus), taken with yellow wine. Cover the patient to induce sweating. If no sweat occurs shortly after, it indicates stagnation and accumulation of toxic heat; still employ diaphoresis and purgation methods to resolve the toxic heat. There is also Yangmao Ding (Wool Ding), where the body presents with chills and fever, and red spots resembling rashes appear on the anterior and posterior chest. First, prick the purple-black spots with a clothing needle until wool-like material emerges, pricking several locations on the front and back. Sweating immediately ensues, leading to recovery.
(Some cases result from puncture wounds by bamboo or wood splinters, or abrasions by sharp porcelain or iron. After ulceration, pain is severe, with frequent discharge of foul fluid, dark purple skin color, and systemic chills and fever. This is fundamentally caused by Yin Deficiency (Yin Xu). Treatment should employ sour and sweet flavors to astringe Yin and tonify deficiency, or salty and bitter flavors to subdue fire and drain heat. Refer to the treatment methods in the Ulcer Section. If mistakenly treated as Ding, the condition will spread and be ineffective, causing great harm.)
