（廿岁以下疳，廿岁以上劳）
脑疳，头皮光急，头发作穗，或有疮肿至囟，囟肿则多损眼。脑热如火，囟脑高，遍身多汗也。
脊疳，虫蚀脊膂骨如锯齿，拍背如鼓鸣，十指背生疮，频咬爪甲，烦热黄瘦也。
走马疳，蚀齿龈，口疮出血，鼻气，齿黑脱落，囟有穴者，名曰走马，盖阳明热气奔如马也。
无辜疳，脑后有核，初生软而不觉痛，其中有虫如米粉，不速破去，则热气渐长，虫随气血流散，侵蚀脏腑，黄
瘦头大，手足细弱，遂至于死也。（古方天有鸟，名曰无辜，昼伏夜游，儿家洗浣衣绷，露天经宿，或遇此鸟飞过，落
羽所污，而与儿穿动，令有此疾也）
丁奚疳，腹大颈细，黄瘦是也。丁者，手足与项极小伶仃也。奚者，腹大也。甚者，尻高肉削，脐突胸满，爱吃
生米、土炭等物也。
哺露疳，虚热往来，头骨分解，反食土虫，烦渴呕哕，骨瘦 露形也。盖诸疳皆因脾胃久虚，形体瘦削而发也，
并宜十全丹。

(For children under twenty years of age, the condition is Gan accumulation; for those over twenty, it is Lao exhaustion.)
Brain Gan (Gan syndrome affecting the brain): The scalp is shiny and tight, hair forms tufts or spikes. There may be sores or swelling extending to the fontanelle; if the fontanelle swells, it often damages the eyes. The head feels hot like fire, the fontanelle bulges, and there is profuse sweating all over the body.
Spine Gan (Gan syndrome affecting the spine): Parasites erode the spinal bones like saw teeth; tapping the back produces a drum-like sound. Sores appear on the backs of the ten fingers, the patient frequently bites their fingernails, accompanied by irritability, fever, sallow complexion, and emaciation.
Zouma Gan (Running Horse Gan): This condition erodes the gums, causes bleeding from mouth ulcers, foul breath, blackening and loss of teeth. If the fontanelle presents with a pit, it is named "Zouma" (Running Horse), attributed to the surging heat of the Yangming meridian resembling a galloping horse.
Wugu Gan (Innocent Gan): A mass appears behind the ear/head. Initially soft and painless, it contains parasites resembling rice flour. If not promptly ruptured and removed, the pathogenic heat gradually increases, and the parasites disperse via Qi and Blood, damaging the Zang-Fu organs. This leads to sallow complexion, emaciation, a large head, and weak limbs, eventually resulting in death. (Ancient texts mention a bird named "Wugu" that hides during the day and moves at night. If infants' laundry is left exposed overnight and contaminated by feathers from this bird flying overhead, wearing such clothes can cause this disease.)
Dingxi Gan: Abdominal distension with a thin neck, sallow complexion, and emaciation characterize this condition. "Ding" refers to the extreme thinness of the limbs and neck; "Xi" refers to the distended abdomen. In severe cases, the sacrum protrudes, muscles waste away, the umbilicus bulges, and the chest feels full. The patient may crave eating raw rice, soil, or charcoal.
Pulu Gan: Alternating deficiency-heat, splitting of the cranial sutures, pica (eating earthworms), irritability, thirst, vomiting, and retching occur. The bones are emaciated, leaving only skin covering them. Generally, all Gan syndromes arise from long-term Spleen and Stomach deficiency leading to physical wasting. All these conditions are suitable for treatment with Shiquan Dan.
