禀火土之气，感长夏暑热之令以生，味甘，气温，有毒，为散血热除壅毒之要药。
但宜外用，勿轻内服。昔刘氏二子，恣食成痞，人传一方，以木鳖子煮肉食之，当愈二
子，食之俱死，其毒可知矣。经云∶无毒何也？
木鳖子，消肿突恶疮、两跨蚌毒，双乳赤痈肛门肿痛，非专追毒，亦可生肌。番木
鳖形小于木鳖，色白味苦，气大寒，有毒。外敷赤游丹毒，内吹喉痹肿痛，更寒更苦，
甚勿轻用。
禀竹之余气，得霹雳而生，故名雷丸，味苦咸，性微寒，有小毒，入手足阳明经。
苦寒之性故入肠胃而为温热杀虫，化积解毒除狂之用，利丈夫不利女子者，盖以男子属
阳，得阴而生，故喜阴寒之味，女子属阴，得阳而长，故不利阴寒之物也。宜择白者可
用，盖赤者杀人，甘草汁浸一宿，去皮用。
雷丸，胃热可解，蛊毒能驱，善杀三虫，仍杀白虫，惟治男人，不治女子，主癫
痫狂走，疗汗出恶风，又作磨积之膏，专却小儿百病，无虫积者禁之。
禀金气而生于春阳之令，故味苦、辛，气温、无毒。辛能散，苦能下，温能除湿。
故为散风除湿化食杀虫消积消疳之药。然久服多服亦能伤胃者也。
芜荑，经火 过才用。主五内邪气，杀寸白三虫，化食除肠风，逐冷止心痛，散皮
肤骨节风湿，疗痔 疥癣疮痍，脾虚有积，亦勿概投。
木鳖子禀受火与土的气化，感受长夏季节暑热的时令之气而生长，味道甘甜，药性温，有毒，是消散血热、清除壅滞毒邪的重要药物。
但适宜外用，不要轻易内服。过去刘家的两个儿子，因恣意食用导致形成痞块，有人流传一个方子，用木鳖子煮肉给他们吃，本指望能治好这两个儿子，结果两人吃了都死了，其毒性之大由此可见。医经说：“无毒吗？”（意指质疑其是否真的无毒）。
木鳖子能消除肿胀，治疗恶疮、两胯部的疔毒、双侧乳房的赤痈以及肛门肿痛，它不仅能专门追拔毒邪，也能促进肌肉生长。番木鳖形状比木鳖子小，颜色白，味道苦，药性大寒，有毒。外敷可治赤游丹毒，内服可治喉痹肿痛，其性更寒更苦，千万不要轻易使用。
雷丸禀受竹子残余的气化，得雷电霹雳而生，所以名叫雷丸，味道苦咸，药性微寒，有小毒，归入手足阳明经。因其苦寒的性质，故入肠胃，具有温热杀虫、化解积滞、解毒除狂的作用。之所以对男子有利而对女子不利，大概是因为男子属阳，依靠阴气而生，所以喜欢阴寒的味道；女子属阴，依靠阳气而成长，所以不适合阴寒之物。应当选择白色的雷丸使用，因为红色的会致人死亡，需用甘草汁浸泡一夜，去皮后使用。
雷丸能解除胃热，驱除蛊毒，善于杀死三种寄生虫，也能杀死白色寄生虫，只治疗男子，不治疗女子，主治癫痫狂走，治疗出汗怕风，又可制成磨积的膏剂，专门对付小儿的各种疾病，没有虫积的患者禁止服用。
芜荑禀受金气而在春阳时令中生长，所以味道苦、辛，药性温，无毒。辛味能发散，苦味能降泄，温性能除湿。
因此它是疏散风邪、祛除湿气、消化食物、杀虫消积、消除疳积的药物。然而长期或多量服用也会损伤胃气。
芜荑需经过火处理后才可使用。主治五脏内的邪气，杀死寸白虫等三种寄生虫，消化食物、祛除肠风，驱逐寒气停止心痛，散发皮肤骨节的风湿，治疗痔疮、疥癣疮疡，脾虚有积滞的患者，也不要一概投用。
Mubeizi (Strychnos semence) is generated by inheriting the Qi of Fire and Earth, and sensing the heat and dampness of the long summer season. It tastes sweet, has a warm nature, and is toxic. It is an essential herb for dissipating blood-heat and removing stagnant toxins.
However, it is suitable only for external use; internal administration should not be undertaken lightly. In the past, two sons of the Liu family developed abdominal masses due to excessive consumption of certain foods. A folk prescription circulated suggested boiling Mubeizi with meat for them to eat, expecting to cure the two sons. Instead, both died after ingestion, revealing its toxicity. The classics ask: "Is it truly non-toxic?"
Mubeizi reduces swelling and treats malignant sores, carbuncles in both groins, erysipelas-like abscesses on both breasts, and swelling and pain in the anus. It not only specifically draws out toxins but also promotes tissue regeneration. Fanmubeizi (Semen Strychni) is smaller than Mubeizi, white in color, bitter in taste, cold in nature, and toxic. Applied externally, it treats erysipelas (Chiyou Dandu); internally, it treats throat obstruction with swelling and pain. Its nature is even colder and more bitter; do not use it lightly.
Leiwanz (Fritillaria cirrhosa bulb / Polyporus umbellatus sclerotium - *Note: Context suggests Polyporus or similar antiparasitic, but traditionally Leiwanz refers to Omphalia lapidescens or similar fungal sclerotia used for parasites*) inherits the residual Qi of bamboo and is born from thunderbolts, hence its name. It tastes bitter and salty, has a slightly cold nature, and is slightly toxic. It enters the Hand and Foot Yangming meridians. Due to its bitter-cold nature, it enters the stomach and intestines, acting to kill parasites with warmth, resolve accumulations, detoxify, and calm mania. It benefits men but harms women because men belong to Yang and are born through Yin, thus favoring bitter-cold flavors; women belong to Yin and grow through Yang, thus disfavoring bitter-cold substances. Select white specimens for use, as red ones are lethal. Soak in Licorice Decoction (Gancao Zhi) overnight, remove the skin, and use.
Leiwanz resolves stomach-heat, expels gu-poison, effectively kills three types of intestinal worms, and also kills white worms. It treats men but not women. It is indicated for epilepsy and manic running, sweating with aversion to wind. It can also be processed into a paste for resolving accumulations, specifically treating various pediatric diseases. It is contraindicated in patients without worm accumulation.
Wuyi (Terminalia chebula fruit) is generated by inheriting Metal Qi during the spring yang season. Thus, it tastes bitter and pungent, has a warm nature, and is non-toxic. Pungency disperses, bitterness descends, and warmth removes dampness.
Therefore, it is an herb that disperses wind, removes dampness, aids digestion, kills parasites, resolves accumulations, and eliminates childhood malnutrition syndromes (Gan syndrome). However, long-term or excessive consumption can damage the stomach Qi.
Wuyi must be processed by fire before use. It treats pathogenic factors within the five zang organs, kills tapeworms and other intestinal parasites, aids digestion, removes intestinal wind, expels cold to stop heart pain, disperses wind-dampness in the skin and joints, and treats hemorrhoids, scabies, tinea, and ulcers. For patients with spleen deficiency and food stagnation, it should not be administered indiscriminately.
