骨碎补：味苦，性温，无毒，归入肾经。主治跌打损伤，促进骨骼愈合，祛除风毒引起的疼痛，坚固牙齿，治疗蚀疮（皮肤溃烂），杀灭各种寄生虫。
处理方法是：去除细小的毛刺并锉碎，用蜂蜜拌匀后蒸制，晒干后使用。
按语：骨碎补药性温和且作用趋向下行，专门进入肾脏，用来调理骨骼疾病。牙齿是骨骼的余气所生，所以它能坚固牙齿。又能杀虫的原因，大概是因为虫子生于湿气之中，现在能祛除风毒，从而捣毁了虫子的巢穴，它们怎么能生存呢？
雷公说：凡是采得后，先用铜刀刮去上面黄红色的毛，直到刮干净，然后细细切碎，用蜂蜜拌匀使其湿润，架在柳木甑中蒸一天，取出晾晒干燥后使用，这样药效更稳固。《名医别录》记载：去掉细毛切细后，用生蜜拌匀蒸制，从巳时到亥时（约6小时），照前法晾晒干燥后捣碎使用。炮制猪肾，空腹服用，可治疗耳鸣，也能止各种杂痛。
威灵仙：味苦，性温，无毒，归入十二经脉。主治各种风邪，宣通五脏，祛除腹内冷积停滞，心胸部的痰饮积水，久积形成的症瘕痞块，膀胱内的恶水（病理产物），腰膝冷痛，两脚肿胀满闷，又治疗跌打损伤。忌食面食、浓茶、牛肉、牛乳。采收时听不到流水声的地方采集为佳，铁脚者品质好。
按语：威灵仙既可升提又可下降，属于阴中之阳，所以在经络中没有不能到达的地方。朱丹溪说：它气味纯和，所以对肝脏多有功效，是治疗痛风的重要药物。它的药性善于走窜，多服会耗散人体五脏的真气，然而风邪注着引起的疼痛非此药不能消除，病愈即停，不宜多用。
牛膝：味苦酸，性平，无毒，归入肾经。补益精气，利腰膝，填补骨髓，除去脑漏（鼻渊流浊涕），祛除寒湿，破除血结，通调月经，堕胎引产，调理膀胱气化功能迟缓困难，治疗阴部剧烈疼痛欲死。处理方法是：去掉芦头，用酒浸泡一夜后使用。与龟甲、萤火、陆英相恶（产生拮抗或副作用），畏惧白前、白鲜皮，忌食牛肉。
按语：朱丹溪说：牛膝能引导其他药物下行，适宜进入足少阴肾经以调理各种疾病，妇女服用它，应归于血海，所以它在行血方面有功效，但脾虚气陷及腿膝肿胀的人，不宜使用。牛膝有两种，土牛膝禀赋薄弱，所以短而细，主要作用是破血；川牛膝禀赋较好……
雷公说：凡是使用时，去掉头部和尘土，用黄精的自然汁液浸泡一夜，滤出，细细切碎，焙干后使用。
*Guishubu* (Drynariae Rhizoma): Bitter in taste, warm in nature, non-toxic, enters the Kidney Meridian. It primarily treats traumatic injuries, promotes bone healing, dispels pain caused by toxic wind, strengthens teeth, treats ulcerative sores, and kills various parasites.
Processing method: Remove fine hairs and crush, mix with honey, steam, dry in the sun, and use.
Note: *Guishubu* is warm and directs downward, specifically entering the Kidney system to regulate bone diseases. Teeth are considered the surplus of bones; therefore, it can strengthen them. The reason it can kill parasites is likely because parasites thrive in dampness; by dispelling toxic wind, it destroys their nests, making survival impossible.
Leigong states: Upon collection, first use a copper knife to scrape off all yellow-red hairs on the surface until clean, then finely cut. Mix with honey to moisten, place in a willow-wood steamer, steam for one day, take out, expose to sunlight to dry, and use. This ensures stable efficacy. *Mingyi Bielu* records: After removing fine hairs and cutting finely, mix with raw honey and steam from Si hour to Hai hour (approx. 6 hours), then dry in the sun as before, crush, and use. Processed Pig Kidney eaten on an empty stomach treats tinnitus and also stops various miscellaneous pains.
*Weilingxian* (Clematidis Radix et Rhizoma): Bitter in taste, warm in nature, non-toxic, enters the Twelve Meridians. It primarily treats various wind pathogens, unblocks the Five Zang organs, removes cold stagnation in the abdomen, phlegm-fluid retention in the chest and heart, long-standing masses and lumps (Zhengji), evil water in the bladder, cold pain in the waist and knees, swelling and fullness in both feet, and also treats traumatic injuries. Contraindicated with wheat products, strong tea, beef, and cow's milk. Collection is best done where no flowing water sound is heard; those with iron-colored stems are superior.
Note: *Weilingxian* can ascend and descend, belonging to Yang within Yin, thus penetrating all meridians without obstruction. Zhu Danxi stated: Its flavor is pure and harmonious, thus having many effects on the Liver; it is a key herb for treating gouty arthritis. Its nature is agile and moving; excessive use depletes the True Qi of the Five Zang organs. However, pain caused by wind-dampness infiltration cannot be removed without this herb. Cease use once the disease is cured; it should not be used excessively.
*Niuxi* (Achyranthis Bidentatae Radix): Bitter and sour in taste, neutral in nature, non-toxic, enters the Kidney Meridian. It tonifies Essence and Qi, benefits the waist and knees, fills the marrow, clears nasal discharge (Nao Lou), dispels cold-dampness, breaks blood stasis, regulates menstruation, induces abortion, regulates delayed or difficult bladder Qi transformation, and treats severe pain in the genital region. Processing method: Remove the rhizome head (Lu), soak in wine for one night, and use. It is incompatible with Tortoise Shell (*Guijia*), Firefly (*Yinghuo*), and *Luying*; it fears *Baiqian* and *Baixianpi*. Contraindicated with beef.
Note: Zhu Danxi stated: *Niuxi* guides other herbs downward and is suitable for entering the Foot-Shaoyin Kidney Meridian to treat various diseases. For women, it enters the Sea of Blood, thus having merit in promoting blood circulation. However, it is not suitable for those with Spleen deficiency with Qi sinking, or swelling in the legs and knees. There are two types: *Tu Niuxi* has thin endowment, is short and thin, and mainly breaks blood; *Chuan Niuxi* has better endowment...
Leigong states: When using, remove the head and dust, soak overnight in the natural juice of *Huangjing*, drain, finely cut, bake dry, and use.
