味苦咸，性寒有小毒，入肺脾胃三经。主胃中热，癫发狂走，恶风汗出，解蛊毒，杀
诸虫，逐皮里膜外之水；又作糜膏，除小儿百病，利丈夫，不利女子，久服阴痿。火炮用，
荔实、浓朴、芫花为使，恶葛根、扁蓄，赤者杀人。
按∶雷丸苦能燥脾，而胃则其腑也，肺则其子也，故均入之。虫以湿热为巢穴，湿热去
而虫可杀矣。《本经》既云利丈夫，《别录》又云久服阴痿，于事相反，陶隐居以此致疑，不
知利者疏利之谓尔！非利益也。
雷公云∶凡使用甘草，水浸一宿了，将刀刮去黑皮，破作四五片，又用甘草汤浸一宿后
蒸，从巳至未，日干，却以酒拌如前，日干用之。
味甘苦，性微寒无毒，入十二经。主小儿寒热，诸种惊痫，胎风客忤，热壅夜啼。舒筋
活血，色黄而嫩钩多者佳。
按∶钩藤兼生气血，故于经络靡所不入，惟疗小儿，不入余方。
味甘微咸，性平有小毒，入诸阴经。主五脏邪气，心腹卒痛，除带下，破积血，疗疥
癣恶疮及金疮，生肌止痛，得密陀僧良。有假者是海母血，颇相似，然味大咸有腥气为辨尔
。敲断有光彩，磨指甲红透者佳，另研用。若与别药同捣，化作飞尘。
按∶血竭专主血分，故入诸阴之经。日华子云∶诸疮久不合者，以敷此药。然不可多使，

雷丸：味苦、咸，性寒，有小毒，归肺、脾、胃三经。主治胃中热邪，癫狂发作时的奔走行为，恶风汗出，解除蛊毒，杀灭各种寄生虫，驱除皮里膜外之水湿；又制成糜膏状，可消除小儿多种疾病，对男子有利，但对女子不利，长期服用会导致阳痿（Yinwei, 阳痿）。需用火炮制后使用，以荔实、厚朴、芫花为引使药，畏葛根、扁蓄，红色的雷丸会致人死亡。
按语：雷丸味苦能燥湿健脾，脾的腑是胃，肺是脾的子脏，所以药物均归于这三经。寄生虫以湿热环境作为巢穴，湿热去除后寄生虫便可被杀灭。《神农本草经》既说利丈夫，《名医别录》又说久服导致阳痿，两者看似矛盾，陶隐居因此产生怀疑，却不知道“利”是指疏泄通利之意，并非利益增益之意。
雷公云：凡使用甘草时，先用水浸泡一夜，用刀刮去黑皮，破成四五片，再用甘草汤浸泡一夜后蒸制，从巳时到未时，晒干，然后用酒拌和如前法，再晒干使用。
钩藤：味甘、苦，性微寒，无毒，归十二经。主治小儿寒热往来，各种惊痫，胎风客忤（Tai Feng Ke Wu, 指新生儿受惊吓或外邪侵袭所致病症），热邪壅盛导致的夜间啼哭。能舒缓筋脉，活血，颜色黄且嫩、钩多的品质佳。
按语：钩藤兼能生发气血，所以在经络中没有不能到达的地方，只用于治疗小儿疾病，不进入其他方剂。
血竭：味甘、微咸，性平，有小毒，归诸阴经。主治五脏邪气，心腹突然疼痛，消除带下病，破除瘀血，治疗疥癣恶疮及金创（Jinchuang, 刀剑等金属利器造成的创伤），生肌止痛，与密陀僧（Miduoseng, Litharge）配合使用效果良好。有假冒者是海母血，颇相似，但味道极咸且有腥气可作为辨别依据。敲断后有光彩，磨指甲红透者品质佳，需单独研磨使用。若与其他药物共同捣碎，会变成飞尘。
Leiwan (Polyporus Umbellatus): Bitter and salty in flavor, cold in nature, slightly toxic. Enters the Lung, Spleen, and Stomach meridians. Primarily treats heat in the Stomach, manic episodes with running about, aversion to wind with sweating, resolves gu poison (Gu Du, a type of poisoning or parasitic disease), kills various parasites, and drives out water-dampness from beneath the skin and within membranes. Also prepared as a paste to eliminate various ailments in infants; it is beneficial for men but detrimental to women, and long-term use causes Yinwei (Impotence). It should be used after fire-processing. Li Shi (Litchi seed), Hou Po (Magnolia Bark), and Yuan Hua (Genkwa Flower) are its guiding herbs. It is incompatible with Ge Gen (Pueraria Root) and Bian Xu (Knotweed Herb); red-colored Leiwan is lethal.
Commentary: Leiwan's bitterness can dry dampness and strengthen the Spleen; the Stomach is its paired Fu organ, and the Lung is its Zi (Child) organ, hence it enters all three meridians. Parasites nest in damp-heat environments; once damp-heat is removed, the parasites can be killed. The *Shennong Bencao Jing* states it benefits men, while the *Mingyi Bielu* states long-term use causes impotence, which seems contradictory. Tao Hongjing doubted this, not realizing that "benefit" here refers to purgative or draining action, not general benefit or nourishment.
Leigong says: When using Gan Cao (Licorice Root), soak it in water overnight, scrape off the black skin with a knife, break it into four or five pieces, then soak again in Gan Cao decoction overnight before steaming from Si hour (9-11 AM) to Wei hour (1-3 PM). Sun-dry it, then mix with wine as before, and sun-dry again for use.
Gouteng (Uncaria Rhynchophylla): Sweet and bitter in flavor, slightly cold in nature, non-toxic. Enters the twelve meridians. Primarily treats alternating chills and fever in infants, various types of convulsions and epilepsy, Tai Feng Ke Wu (Infantile Convulsion due to Wind Invasion), and night crying due to heat obstruction. It relaxes sinews and invigorates blood; those that are yellow, tender, and have many hooks are superior.
Commentary: Gouteng generates Qi and Blood, so it penetrates all meridians without exception. It is exclusively used for treating pediatric conditions and does not appear in other prescriptions.
Xuejie (Dragon's Blood): Sweet and slightly salty in flavor, neutral in nature, slightly toxic. Enters the Yin meridians. Primarily treats pathogenic factors in the five Zang organs, sudden pain in the heart and abdomen, eliminates leukorrhea, breaks up accumulated blood stasis, treats scabies, tinea, malignant sores, and Jinchuang (Metal Wounds/Incised Injuries), promotes tissue regeneration, and relieves pain. It works well when combined with Miduoseng (Litharge). Counterfeits exist, such as Sea Mother Blood (Hai Mu Xue), which is similar but distinguished by an extremely salty taste and fishy odor. Those that show luster when broken and stain fingernails red when rubbed are superior. They must be ground separately. If pounded together with other herbs, they turn into flying dust.
Commentary: Xuejie specifically governs the Blood level, hence it enters the Yin meridians. Ri Huazi stated: For chronic ulcers that fail to heal, apply this herb. However, it should not be used in large quantities...
