鼠 者，由饮食不择，虫蛆毒变化，入腑脏，出于脉，稽留脉内而不去，使人寒热。
其根在肺。出于颈掖之间。其浮于脉中，而未内着于肌肉，而外为脓血者，易去也。
决其生死者，反其目视之，其中有赤脉，从上下贯瞳子，见一脉，一岁死；见一脉半，
一岁半死；见二脉，二岁死；见二脉半，二岁半死；见三脉，三岁死。赤脉而不下贯瞳子，
《养生方》云∶正月勿食鼠残食，作鼠 ，发于颈项；或毒入腹，下血不止；或口生疮
蜂 者，由饮食劳倦，渴乏多饮流水，即得蜂毒，流入于脏。其根在脾。出发于颈项，
历历三四处，或累累四五处蜂台，或发胸前俱肿，以溃生疮，状如痈形，瘥而复移。
蚁 者，由饮食有蚁精气，毒入于五脏，流出经络，多着颈项，戢戢然小肿核细，乃遍
蚍蜉 者，由饮食内有蚍蜉毒瓦斯，入于脏，流于经脉，使身寒似伤寒，腹虚胪胀。其根
在肺。发于颈项，如疥癣，娄娄孔出。初生痒，搔之生痕。不治，一百日生蚍蜉 。
此由饮食内有蝇窠子，因误食之，入于肠胃，流注入血脉，变化生 。发于颈下，初生
痒，币币如蝇窠子状，使人寒热，久，其中化生蝇也。
蝼蛄 者，由食果 子，不避有虫，即便啖之，有虫气入于腹内，外发于颈。
其根在大肠。初生之时，其状如风矢，亦如蜗形，瘾胗而痒，搔之则引大如四寸。更其中生
道，乃有数十；中生蝼蛄，亦有十数。不治，二年杀人。
鼠瘰（由虫毒引起的颈部淋巴结结核），是由于饮食不洁，虫蛆毒素变化，侵入腑脏，出于血脉，稽留于脉内而不离去，导致人体出现寒热症状。
其病根在肺。病变出现在颈腋之间。如果肿块浮于脉中，尚未深入肌肉，而外部化为脓血者，容易治愈。
判断其生死预后，需观察其眼睛，其中若有赤色脉络，从上下贯穿瞳孔，见到一条赤脉，预示一年死；见到一条半赤脉，预示一年半死；见到两条赤脉，预示两年死；见到两条半赤脉，预示两年半死；见到三条赤脉，预示三年死。若赤色脉络不向下贯穿瞳孔，
《养生方》说：正月不要吃老鼠吃剩的食物，否则会引发鼠瘰，发作于颈项；或者毒素进入腹部，导致下血不止；或者口腔生疮。
蜂瘰（类似蜂窝状或簇集状的颈部淋巴结结核），是由于饮食劳倦，口渴时大量饮用生水，从而获得蜂毒，流入脏腑。其病根在脾。病变出发于颈项，
历历可数三四处，或者累累成串四五处如蜂房状，或者发作于胸前全部肿胀，溃破后生疮，形状像痈肿，痊愈后又转移他处。
蚁瘰（类似蚂蚁巢穴状的小结节），是由于饮食摄入了蚂蚁的精气，毒素进入五脏，流出经络，多附着于颈项，细小密集地形成小肿核，甚至遍布全身。
蚍蜉瘰（大蚂蚁引发的瘰疬），是由于饮食中含有蚍蜉（大蚂蚁）的毒气，进入脏腑，流注于经脉，使身体发冷类似伤寒，腹部虚胀。其病根在肺。病变发于颈项，像疥癣一样，娄娄孔出。初起时瘙痒，搔抓后留下痕迹。若不治疗，一百天后会生出蚍蜉瘰。
蝇瘰（苍蝇幼虫引发的瘰疬），是由于饮食中含有蝇窠子（苍蝇卵或幼虫），因误食而入肠胃，流注入血脉，变化生成蝇瘰。发作于颈下，初起时瘙痒，币币（形容聚集貌）如蝇窠子状，使人寒热，日久，其中化生苍蝇。
蝼蛄瘰（蝼蛄引发的瘰疬），是由于食用了带有虫子的果子，不避开有虫的部分就立即吞食，虫气进入腹内，外发于颈部。
其病根在大肠。初起时，形状像风矢（风疹块），也像蜗牛形，瘾胗（皮肤突起）而痒，搔抓后则牵引肿大如四寸长。更在其间生道，竟有数十条；中生蝼蛄，也有十数只。若不治疗，两年内致死。
Lymphatic Tuberculosis (Shu, caused by insect toxins), arises from unclean diet where worm and maggot toxins transform, invade the fu organs, emerge into the meridians, remain stagnant within the vessels without departing, causing chills and fever in the body.
The root of the disease lies in the Lung. It manifests between the neck and axilla. If the swelling floats within the vessels, has not yet penetrated into the muscles, but externally suppurates into pus and blood, it is easy to cure.
To determine life or death prognosis, observe the eyes: if red vessels are seen penetrating vertically through the pupil, seeing one vessel indicates death in one year; seeing one and a half vessels indicates death in one and a half years; seeing two vessels indicates death in two years; seeing two and a half vessels indicates death in two and a half years; seeing three vessels indicates death in three years. If the red vessels do not penetrate downward through the pupil,
the *Yangsheng Fang* states: In the first lunar month, do not eat leftover food consumed by rats, as this will induce Shu lymphatic tuberculosis manifesting on the neck and nape; or if toxins enter the abdomen, it causes continuous bloody diarrhea; or sores may form in the mouth.
Bee-like Lymphatic Tuberculosis (Feng), arises from dietary labor and fatigue, drinking large amounts of running water when thirsty, thereby acquiring bee toxin which flows into the zang organs. The root lies in the Spleen. It originates at the neck, appearing clearly in three or four places, or clustered in four or five places like honeycombs, or swelling entirely on the chest, ulcerating into sores resembling carbuncles, healing only to recur elsewhere.
Ant-like Lymphatic Tuberculosis (Yi), arises from ingesting the essence of ants in diet, where toxin enters the five zang organs, flows out through the collaterals, mostly attaching to the neck, forming small, dense nodules that may spread throughout the body.
Pishu Lymphatic Tuberculosis (Pifu), arises from ingesting toxins of Pifu (large ants) in diet, entering the zang organs and flowing into the meridians, causing the body to feel cold similar to Cold Damage (Shanghan), with abdominal distension due to deficiency. The root lies in the Lung. It manifests on the neck, resembling scabies or tinea, emerging in clusters. Initially itchy, scratching leaves marks. If untreated, Pifu lymphatic tuberculosis will develop after one hundred days.
Fly Lymphatic Tuberculosis (Ying), arises from accidentally ingesting fly nests (eggs/larvae) in diet, entering the stomach and intestines, flowing into the blood vessels, transforming into Ying lymphatic tuberculosis. It manifests under the neck, initially itchy, clustering like fly nests, causing chills and fever. Over time, flies may be generated within.
Mole Cricket Lymphatic Tuberculosis (Lougu), arises from eating fruits containing insects, swallowing them without avoiding the infested parts, allowing insect qi to enter the abdomen and manifest externally on the neck.
The root lies in the Large Intestine. Initially, the shape resembles wind-induced wheals (Fengshi) or snail shells, presenting as itchy skin eruptions; scratching causes them to swell up to four cun in length. Channels form within, numbering dozens; mole crickets may also appear within, numbering ten or more. If untreated, it leads to death within two years.
