味辛，性生温熟寒，有大毒，入脾胃大肠三经。主消坚积，荡脏腑之沉寒，通闭塞，
利水谷之道路，排脓消肿，破血通经，杀鬼毒蛊疰及腹脏诸蛊。去皮心膜油，水煮五度用，
芫花为使，恶 草，畏大黄、黄连、藜芦、牵牛、芦笋、酱豉、冷水，杀斑蝥蛇蝎毒。
按∶巴豆专主宣通，则脾胃大肠宜其入已。炒令紫黑，可以通肠，亦可止泻。盖通因通

譬如

【巴豆】
味辛，生用性温，熟用性寒，有大毒，归入脾、胃、大肠三经。主要功效是消除坚硬的积滞，荡涤脏腑深处的沉寒，疏通闭塞，通畅水谷运行的道路，排出脓液并消肿，破除瘀血并通调经脉，杀灭鬼毒、蛊疰以及腹脏的各种蛊毒。使用时需去除皮、心、膜和油，用水煮五次后使用；以芫花为引药（使药），畏恶草，畏惧大黄、黄连、藜芦、牵牛子、芦笋、酱豉、冷水，能杀死斑蝥、蛇、蝎的毒。
按语：巴豆专门主管宣通，所以脾胃和大肠适宜它进入。炒至紫黑色，可以通便，也可以止泻。这体现了“通因通用”的治疗原则。张仲景、李东垣及各位名医，常常使用它。如今世俗之人畏惧其辛热之毒和荡涤带来的危害，往往称之为劫剂（猛烈的药剂），废弃而不再使用。他们不知道巴豆是像斩关夺门的将领一样，药性猛烈，如果投用不当，危害不轻；但如果使用得当，见效非常迅速。
雷公说：凡是使用巴豆、巴豆（此处指另一种形态或别名，原文可能有误或特指）及刚子，必须仔细辨认，不要误用导致杀人。巴豆颗粒小且紧实，颜色黄。豆即颗，有三棱，颜色黑。如果是刚子，形状小得像枣核，两头尖，巴豆和豆可以使用，刚子则不使用。凡是加工巴豆，敲碎后，用麻油和酒等量一起煮，研磨成膏后使用。每次加工一两巴豆，以酒和麻油各七合为限度。
【金铃子】
味苦，性寒。有小毒，归入心、小肠二经。主要治疗温病伤寒，调理大热引起的癫狂，利小便，通水道，杀灭三虫，治愈疮疡，善于消除心痛，适宜制作成洗浴汤剂。晒干后用酒蒸，去除皮和核使用，四川蜀地出产的质量较好。
按语：金铃子味苦性寒，适宜入心经，而小肠是其腑，所以一并归入。疮疡各种证候，哪不是心火所致？得到金铃子来清泻，确实可以痊愈。
【紫葳】
味甘酸，性微寒，无毒，归入脾、肝二经。主要治疗妇人产后血崩不止，血隔游风，崩漏带下，症瘕血闭，安胎并通淋；又主治热风及身体瘙痒的风疹，大小便不通，酒渣鼻热毒。畏惧卤咸之物，又名凌霄花。
[Ba Dou (Croton Seed)]
Pungent in flavor, warm in nature when raw and cold when cooked, possessing great toxicity. It enters the Spleen, Stomach, and Large Intestine meridians. It primarily eliminates hard accumulations, sweeps away deep-seated cold in the Zang-Fu organs, unblocks obstructions, facilitates the passage of water and grain, expels pus and reduces swelling, breaks blood stasis and unblocks the collaterals, and kills ghost toxins, Gu Zhu (parasitic diseases), and various internal parasites. The skin, heart, membrane, and oil must be removed; it is boiled in water five times before use. Yuan Hua (Genkwa Flos) serves as the guiding herb (Shi). It is incompatible with Cao Cao (likely referring to a specific herb or typo for 草), and fears Da Huang (Rhubarb Radix et Rhizoma), Huang Lian (Coptidis Rhizoma), Li Lu (Veratri Radix), Qian Niu Zi (Pharbitidis Semen), Lu Sun (Asparagus Fern Shoots), Jiang Chi (Fermented Soybean Paste), and cold water. It can neutralize the venom of Meloides beetles, snakes, and scorpions.
Commentary: Ba Dou specializes in promoting circulation and unblocking, making it suitable for the Spleen, Stomach, and Large Intestine. When stir-fried until purple-black, it can promote bowel movements or stop diarrhea. This embodies the principle of "treating obstruction with unblocking methods" (Tong Yin Tong Yong). Zhang Zhongjing, Li Dongyuan, and other renowned physicians frequently used it. However, modern people fear its pungent-heat toxicity and the destructive effects of purgation, often labeling it as a "Jie Ji" (robust/forceful remedy) and abandoning its use. They fail to realize that Ba Dou is like a general who breaches gates and seizes doors; its nature is fierce. If administered improperly, it causes significant harm; if used appropriately, it yields rapid results.
Lei Gong stated: "When using Ba Dou, Ba Dou (variant name), and Gang Zi, one must carefully distinguish them to avoid fatal errors. Ba Dou grains are small, tight, and solid, with a yellow color. 'Dou' refers to the grain shape with three edges, black in color. 'Gang Zi' is small like a jujube pit, pointed at both ends. Use Ba Dou and the bean form, but do not use Gang Zi." For processing, crack the seeds, boil them with equal parts sesame oil and wine, then grind into a paste. For every liang (approx. 37g) processed, use seven he (approx. 140ml) each of wine and sesame oil.
[Jin Ling Zi (Chloranthus Fruit / Melia Toosendan Fruit)]
Bitter in flavor, cold in nature. Possessing slight toxicity. It enters the Heart and Small Intestine meridians. It primarily treats warm diseases and shanghan (cold damage), regulates mania caused by high fever, promotes urination, unblocks water passages, kills intestinal parasites, heals sores and ulcers, effectively relieves heart pain, and is suitable for making bath decoctions. Sun-dry, steam with wine, remove the skin and seeds, and use. Those from Sichuan are considered superior.
Commentary: Jin Ling Zi is bitter and cold, making it suitable for entering the Heart system, while the Small Intestine is its paired fu organ, hence it enters both. Sores and ulcers are all caused by Heart fire; with Jin Ling Zi to drain the heat, they can indeed be cured.
[Zi Wei (Bignonia Flower / Trumpet Vine Flower)]
Sweet and sour in flavor, slightly cold in nature, non-toxic. It enters the Spleen and Liver meridians. It primarily treats postpartum metrorrhagia that does not cease, blood stasis with wandering wind, leukorrhea due to flooding, abdominal masses (Zheng Jia) with amenorrhea, calms the fetus, and promotes urination. It also treats wind-heat, pruritus and urticaria, constipation and dysuria, and the heat-toxin of rhinophyma (wine nose). It fears halogenated salty substances. Also known as Ling Xiao Hua.
Commentary: Zi Wei's sweet flavor returns to the Spleen, and its sour flavor moves to the Liver. These two meridians store and envelop blood, so it specializes in regulating blood disorders. The generation of wind and itching is also due to disharmony between Ying (Nutrient) and Wei (Defensive) Qi...
