（苏木）具有泻下、行血祛风的作用。
味甘、咸、辛，性平。入三阴经的血分。能行血去瘀。宣散表里之风。（李元素说：适宜与防风同用，但此药治疗风的机理，即是“治风先治血，血行风自灭”的道理，不宜与防风同用。）治疗产后血晕、腹部胀满欲死之症。（葛洪《肘后备急方》中，煮汁服用；海药方中，加乳香和酒服用，这些皆适用于产后败血上冲的实证。若兼有虚喘、面色发黑欲死，乃是败血乘虚侵入肺脏所致，可用苏木二两，水两碗，煮至一碗，加入人参末一两服用，根据情况随时加减，效果神妙不可言说。若产后失血过多，气随血脱，脉象微弱、精神疲倦、口鼻气息寒冷、胸腹无积滞而晕厥者，适宜单用大剂量的独参汤（Ginseng Monoparty Decoction），以固护正气防止虚脱。）治疗血痛、血瘀、月经闭止、气机壅塞、痈肿及跌打损伤。排脓止痛。没有瘀滞者忌用。出自苏方国。（因此忌用铁器。（将苏木研末外敷于刀斧切断的手指处，外部用蚕茧包裹固定，即可接合。）
（干漆）具有泻下、破血消积杀虫的作用。
味辛，性温，有毒且猛烈。功效专于行血杀虫，破除年深日久的凝结积滞瘀血，接续筋骨绝伤。（损伤必然导致瘀血停滞。）血液见到干漆，就会化为水状。其能损害新血的性质可以推知。体虚之人以及经常生大疮的人禁止使用。不要被朱丹溪关于干漆兼有补益作用的说法所误导。（所有内服汤剂均可解其毒，患漆疮者可洗浴之。）炒至烟尽为度。或烧至存性。半夏为其引经药。畏惧川椒、紫苏、鸡蛋、螃蟹。（漆遇到螃蟹就会化成水。）
（大风子）燥痰，外用治疗疮疡。
味辛，性热，有毒。取其油。治疗疮癣疥疠。有杀虫劫毒的功效。（朱丹溪说：粗劣的医生治疗大风病，辅助使用大风子油，却不知道此物性热，有燥痰的功效却会伤血，导致有病将愈却先失明的情况。）出自南番。子中有白色种仁。时间久了则出油变黄不再有效。用于丸药时，需压榨去油。（《寿域神方》，治疗手背皱裂，将大风子捣成泥涂抹。）
(Su Mu, *Lignum Dalbergiae Odoriferae*) has the effects of purging, promoting blood circulation, and dispelling wind.
Sweet, salty, and acrid in flavor; neutral in nature. Enters the blood aspect of the Three Yin meridians. Promotes blood circulation and removes stasis. Disperses wind from the exterior and interior. (Li Yuan said: It is suitable to be used with Fangfeng (*Saposhnikoviae Radix*), but the mechanism by which this herb treats wind is precisely the principle that "to treat wind, first treat the blood; when blood flows, wind extinguishes itself," so it should not be used with Fangfeng.) Treats postpartum blood syncope and abdominal distension feeling as if death were imminent. (In Ge Hong's *Zhouhou Beiji Fang*, decocted juice is taken orally; in Haiyao Fang, Frankincense (*Ruxiang, Boswelliae Resina*) and wine are added. These applications are for excess patterns caused by postpartum failed blood rushing upward. If accompanied by deficiency-type panting, blackish complexion, and a sensation of impending death, it indicates failed blood invading the Lung due to deficiency. Use two liang of Su Mu, two bowls of water, decoct to one bowl, add one liang of Ginseng powder (*Renshen, Ginseng Radix et Rhizoma*), and adjust according to circumstances. The efficacy is miraculous beyond words. If there is excessive blood loss after childbirth, Qi follows Blood out, pulse is faint, spirit is fatigued, breath from mouth and nose is cold, and syncope occurs without stagnation in chest or abdomen, it is appropriate to use a large dose of Dushen Tang (*Ginseng Monoparty Decoction*) alone to secure the collapse.) Treats blood pain, blood stasis, amenorrhea, Qi congestion, carbuncles, and traumatic injuries. Expels pus and relieves pain. Contraindicated in cases without stasis. Originates from Sufang Country. (Therefore, iron is contraindicated. (Apply powdered Su Mu externally to fingers severed by knives or axes, bind tightly with silkworm cocoons externally, and the finger can be reattached.))
(Gan Qi, *Resina Toxodendri*) has the effects of purging, breaking blood stasis, eliminating accumulation, and killing parasites.
Acrid in flavor; warm in nature; toxic and fierce. Its function specializes in promoting blood circulation, killing parasites, and breaking deep-seated凝结 accumulations and blood stasis, reconnecting severed bones and tendons. (Trauma inevitably leads to blood stasis stagnation.) When blood encounters Gan Qi, it turns into water. Its ability to damage new blood can be inferred. Contraindicated for deficient individuals and those prone to severe skin ulcers. Do not be misled by Zhu Danxi's claim that Gan Qi also has tonifying properties. (All internal decoctions can resolve its toxicity; those suffering from lacquer dermatitis can bathe in it.) Stir-fry until smoke ceases. Or calcine to retain its character. Banxia (*Pinelliae Rhizoma*) serves as its guiding herb. Incompatible with Chuanjiao (*Zanthoxyli Pericarpium*), Zisu (*Perillae Folium*), eggs, and crabs. (Lacquer turns to water when encountering crabs.)
(Dafengzi, *Semis Crotonis Tiglii*) dries phlegm; externally used to treat sores.
Acrid in flavor; hot in nature; toxic. Extract the oil. Treats sores, tinea, scabies, and leprosy. Has the power to kill parasites and purge toxins. (Zhu Danxi said: Unskilled physicians treating Big Wind disease (*Elephantiasis*) assist with Dafengzi oil, unaware that this substance is hot in nature, has the effect of drying phlegm but damages blood, leading to cases where patients lose their sight before their illness heals.) Originates from Southern Barbarian lands. Contains white kernels inside the seeds. Over time, the oil turns yellow and becomes ineffective. Used in pill preparations, press out the oil. (*Shouyu Shenfang*, for treating cracked backs of hands, crush Dafengzi into a paste and apply.)
