营分不足，无以荣筋，筋急作痛者，有肌表不密，外风内乘，久郁化热，耗营燥络，
使筋脉枯涩，周身软弱，串疼无休者，脉数而弦，以养阴润燥汤（方见后）。缓治自效。
阴寒内伏，逼其浮火外散，舌润脉沉迟而虚，发斑如蚊咬痕，当服理中汤（方见后）。若
夫时邪所发为阳，初时寒热，或脉静身凉，或又呕恶烦乱，渴不喜饮，头疼有汗，是邪陷
胃腑，而逼营分热蒸液耗而然（治法见前）。设早误苦寒药，使营气冰凝，则斑内隐，神昏
谵语，恐无救法。
奔走热足骤入冷水浸洗，或在水中劳作。凡人动则毛孔开，寒湿之气内袭，致脉络阻
滞，气机为之不运，难以蒸变，阴液为血所聚。隧道者，皆水，肌肉呆板肿亮，日大不

先天不足之婴孩，若吮乳汁，不为肌肤，则精气无以上充髓海，肢体消瘦，惟头颅日
见胖大亮白，令人可骇，有发此症未日久而殇者，亦有延数年者，治之徒费手无功。昔
见盐商之子，用真人参研末，做棉帽冬夏久戴，长成者，只可广人之见闻，天下能有几
钜富者，其力皆可购参乎？况真者觅于何处乎？他孩用之，果能皆效乎？
瘰为小者， 为大者。症原与治法，前贤论之极详，究难遍试。大都多由肝经忿郁，胃

热则肿，结久不散乃成。推之动者，烙以火针。及已溃烂者，俱常贴五苔头草膏，（方见《青囊

有食鼠食剩物，与虚体劳伤而生者。
营阴不足，无法濡养筋脉，导致筋脉拘急疼痛；或因肌表腠理不固，外风侵入体内，日久郁结化热，耗伤营血、燥伤络脉，致使筋脉干枯涩滞，全身软弱无力，疼痛游走不定、无休止者，脉象表现为数而弦，宜服用养阴润燥汤（方剂见后）。缓慢调治自能见效。
阴寒之邪潜伏于内，逼迫虚浮之火向外发散，症见舌面湿润、脉象沉迟且虚弱，皮肤出现如蚊虫叮咬痕迹般的斑疹，应当服用理中汤（方剂见后）。如果是时行邪气引发的阳证，初起时有寒热往来，或者脉象平静、身体凉爽，或者又出现呕吐恶心、心烦意乱、口渴但不想喝水、头痛且有汗出，这是邪气陷入胃腑，逼迫营分热气蒸腾、津液耗损所致（治疗方法见前）。如果过早误用苦寒药物，使营气凝滞如冰，则斑疹隐没不出，出现神志昏迷、胡言乱语，恐怕难以救治。
奔跑发热或脚部发热时突然进入冷水浸泡清洗，或者在水中劳作。凡人在活动时毛孔张开，寒湿之气乘虚内袭，导致脉络阻滞，气机运行不畅，难以蒸腾气化，阴液与血液聚结。所谓“隧道”（指经络血脉），皆由水液构成，肌肉僵硬板结、肿胀发亮，日渐肿大却无法通过汗液排泄。初期可用艾针针刺艾灸，配合服用药酒，或许可以消退细小症状，若拖延日久则成足部顽疾。
先天禀赋不足的婴儿，如果吸吮乳汁不能转化为肌肤营养，则精气无法上充髓海（脑），导致肢体消瘦，只有头颅日渐变大、光亮苍白，令人惊骇。有患此症不久便夭折的，也有延续数年的，治疗往往徒劳无功。昔日曾见盐商之子，用人参研末做成棉帽，冬夏长期佩戴，最终健康成长。这只能拓宽人们的见识，天下能有几位极其富有的人，其财力都能购买人参呢？况且真正的人参又能在何处寻得呢？其他孩子使用这种方法，果真都能有效吗？
颈侧淋巴结肿大为瘰疬，肿块较大者为马刀。病症根源及治疗方法，前代贤人已论述得非常详细，但终究难以普遍适用。大多由于肝经愤怒抑郁，胃腑痰瘀阻滞，经络不通畅，致使痰随气上升至颈部。盖因气和痰，都能蕴结化为热邪。气遇到痰则凝结，痰遇到热则肿胀，结聚日久不散便形成病灶。推之可动者，用火针烙治。已经溃烂者，均常贴敷五苔头草膏（方剂见《青囊集》，一膏贴十日）。内服清肝化痰丸（方剂见后），非数月不能痊愈。推之不动，并牵连至胸胁部位者难治。还有因食用老鼠吃剩的食物，以及体质虚弱劳累损伤而生发的。
Ying (Nutritive) level deficiency fails to nourish the sinews, leading to tendon tension and pain; or due to loose exterior defense allowing external Wind to invade internally, where it stagnates for a long time and transforms into Heat, consuming Ying blood and drying the collaterals. This causes the sinews and vessels to become withered and astringent, resulting in whole-body weakness and continuous, wandering pain without cessation. The pulse is rapid and wiry. Administer Yangyin Rundao Tang (Nourishing Yin and Moistening Dryness Decoction) (see formula later). Slow treatment will naturally yield results.
Internal latent Yin-Cold forces floating Fire to scatter outward. Symptoms include a moist tongue, a deep, slow, and deficient pulse, and macules resembling mosquito bites on the skin. One should administer Lizhong Tang (Regulate the Middle Decoction) (see formula later). If the eruption is caused by seasonal pathogens manifesting as Yang syndrome, initially there may be alternating chills and fever, or a calm pulse with cool body temperature, or additionally vomiting, nausea, restlessness, thirst without desire to drink, headache with sweating. This indicates pathogenic factors sinking into the Stomach Fu organ, forcing Heat to steam within the Ying level and consume fluids (see therapeutic methods earlier). If bitter-cold medicines are mistakenly administered early, causing Ying Qi to congeal like ice, the macules will remain hidden, accompanied by coma and delirious speech, which may be incurable.
After running or when feet are hot, suddenly immersing them in cold water for washing, or working in water. When people move, their pores open, allowing Cold-Dampness to invade internally. This obstructs the meridians and collaterals, hindering the movement of Qi mechanism, making steaming and transformation difficult. Yin fluids aggregate with Blood. The "tunnels" (referring to meridians and vessels), composed largely of fluid, result in muscles becoming stiff, board-like, swollen, and shiny, enlarging daily without sweat excretion. Initially, moxibustion and acupuncture with mugwort can be used, assisted by medicinal wine, which might reduce minor symptoms. If prolonged, it becomes a chronic affliction of the foot.
Infants with congenital insufficiency, if sucking breast milk fails to transform into muscle and flesh, then Essence and Qi cannot ascend to fill the Marrow Sea (brain). This leads to emaciation of the limbs, while the head becomes increasingly large, bright, and white, which is alarming. Some die shortly after onset, while others survive for years; treatment is often futile. I once saw the son of a salt merchant who ground real Ren Shen (Ginseng Root) into powder, made cotton caps, and wore them for long periods in winter and summer, growing up healthy. This merely broadens one's horizons; how many extremely wealthy individuals in the world have the resources to purchase Ginseng? Moreover, where can genuine Ginseng be found? Would other children benefit from this method?
Small neck masses are called Lueli (Scrofula), while larger ones are called Madao (Horseshoe abscess). The etiology and treatment methods were discussed in great detail by former sages, yet they are difficult to apply universally. Most cases arise from Liver Meridian anger and depression, Phlegm and Blood stasis in the Stomach Fu, and unsmooth meridians, causing Phlegm to rise with Qi to the neck. Both Qi and Phlegm can accumulate and transform into Heat. Qi coagulates upon encountering Phlegm; Phlegm swells upon encountering Heat. Long-standing accumulation forms the lesion. For movable masses, treat with fire needle cauterization. For ulcerated lesions, regularly apply Wuta Toucao Gao (Five-Point Head Grass Plaster) (see *Qingnang Ji*, one plaster lasts ten days). Internally administer Qinggan Huatan Wan (Clear Liver and Resolve Phlegm Pill) (see formula later); recovery requires several months. Masses that are immobile and spread to the chest and hypochondrium are difficult to treat. There are also cases arising from eating food remnants left by rats, or from constitutional deficiency and overwork injury.
