味甘，性平无毒，入肾经。主丈夫精滑遗泄，妇人崩中带下，止肠风下血，疗泻痢不 止，得五色具者佳，其齿主惊痫狂疾，俱畏干漆、蜀、椒、理石、石膏。
译文：龙骨味道甘，性质平和，没有毒性，归入肾经。主要治疗男子精气滑脱、遗精早泄，妇女崩漏及带下病，停止肠道风邪引起的便血，治疗腹泻痢疾不止，如果能得到具备五种颜色的龙骨则更好；它的牙齿主要用于治疗惊恐、癫痫和狂躁疾病，但龙骨与干漆、蜀椒、理石、石膏相畏（即不宜同用）。
按∶《经》曰∶肾主骨，宜龙骨独入之。观其沾舌，大抵啬之用居多，故主精滑等症。 经曰∶涩可去脱，是之谓耶。
译文：按语：《内经》说：肾主管骨骼，所以龙骨特别适宜入肾经。观察它粘舌的特性，大多是因为它具有收敛固涩的作用，因此主要用于治疗精气滑脱等症状。医经说：涩味药物可以去除滑脱不禁的病证，说的就是这种情况吧。
味辛，性微热无毒，入肾经。主邪气鬼疰，筋骨毒风挛急。酥炙用，畏干漆、蜀椒、 磁石。
译文：虎骨味道辛，性质微热，没有毒性，归入肾经。主要治疗邪气、鬼疰（一种慢性消耗性疾病）、筋骨间的毒风和筋脉拘挛紧急。使用时需用酥油炙烤，虎骨与干漆、蜀椒、磁石相畏。
按∶虎骨入肾，亦以肾主骨故也。其治骨间毒风者何也？《易》曰∶风从虎，夫风，木 也，虎、金也；木受金制，焉得不从。
译文：按语：虎骨入肾经，也是因为肾主管骨骼的缘故。那它为什么能治疗骨间毒风呢？《易经》说：风跟随老虎而生。风，在五行中属木；虎，在五行中属金；木受到金的制约，怎么能不顺从呢？
雷公云∶虎睛，凡使须问猎人，其眼有雌有雄，有老有嫩，有杀得者，惟中有毒箭死者 勿使，能伤人。凡用虎睛先于草羊血中浸一宿，漉出微微火上焙干，捣成粉，候众药出取合 用之也。
译文：雷公说：使用虎睛时，必须询问猎人，虎眼有雌雄之分，有老嫩之别，有的是猎杀所得，只有那些因中毒箭而死的老虎的眼睛不能使用，因为会伤害人体。凡是使用虎睛，需先在草羊血中浸泡一夜，捞出后在微火上焙干，捣成粉末，等待其他药物准备好后混合使用。
味苦酸咸，性寒无毒，入心肝二经。主百毒蛊疰，鬼魅邪气，伤寒瘟疫，烦躁癫狂， 痘疹血热，痈疽肿毒，清心镇肝，明目定惊，孕妇忌服。须纹细色乌光明滑润者佳，取其茸 尖，功力具备，松脂为使，恶雷丸，忌盐。
译文：犀角味道苦、酸、咸，性质寒凉，没有毒性，归入心和肝两经。主要治疗各种毒素、蛊疰、鬼魅邪气、伤寒瘟疫、烦躁癫狂、痘疹血热、痈疽肿毒，具有清心火、镇肝阳、明目、定惊的功效，孕妇禁止服用。以纹理细致、颜色乌黑光亮、滑润者为佳，取其角尖部分，功效完备，以松脂为引药，畏惧雷丸，忌食盐。
按∶犀角苦寒，本入心家泻火，又入肝脏者，盖以火不妄炎，则金能制木也。丹溪曰∶ 属阳性走，比诸角犹甚，痘疮后用以散余毒，俗以为常，若非有余毒而血虚者，与以燥发热 者用之，祸无极矣。
译文：按语：犀角味苦性寒，本来入心经以泻心火，又入肝经的原因，大概是因为心火不妄动上炎，则肺金能正常制约肝木。朱丹溪说：犀角属于阳性且善于走窜，比其他动物的角更为猛烈，痘疮痊愈后用来发散余毒，这是世俗常见的用法，但如果患者并非有余毒而是血虚，却给予这种燥热性质的药物使用，灾祸将是无穷无尽的。
雷公云∶凡使勿用奴犀角，病水犀、挛子犀、无润犀，惟取乌黑肌皱折裂光润者上。凡 修治时锉其屑入臼中，杵令细，再入臼中研万匝，方入药用，妇人有妊勿服，能消胎气，忌 盐。
译文：雷公说：使用时不要使用奴犀角、病水犀、挛子犀、无润犀，只选取乌黑色、表皮有皱纹褶皱、裂纹且光滑润泽的上品。凡是炮制时，将其锉成碎屑放入臼中，舂捣使其细碎，再放入臼中研磨一万次，然后才能入药使用。怀孕妇女不要服用，因为它能消除胎气，忌食盐。
味苦咸，性寒无毒，入肝经。主伤寒热在肌肤，温气注伏在骨间，邪气不祥，惊梦狂越， 心神不宁，小儿卒热惊搐，产后败血冲心。清心解毒，明目益气。烧灰又主食噎不通，其角 多倒卦痕深入者为真。
译文：羚羊角味道苦、咸，性质寒凉，没有毒性，归入肝经。主要治疗伤寒热邪在肌肤，温邪潜伏在骨间，邪气不祥，惊悸多梦、狂乱超越，心神不安，小儿突发高热惊厥抽搐，产后瘀血冲心。具有清心解毒、明目益气的功效。烧成灰后还可以治疗饮食噎塞不通，其角上有倒卦痕迹且深入内部的为真品。
按∶丹溪曰∶羚羊属木，宜入厥阴，木得其平，而风火诸症无能乘矣。
译文：按语：朱丹溪说：羚羊五行属木，适宜入足厥阴肝经，肝木之气得以平和，那么风火等病症就无法趁虚侵袭了。
雷公云∶凡用有神羊角，其神羊角长有二十四节，内有天生木胎，此角有神力，可抵千 牛之力也。凡修事之时，勿令单用，不复有验，须要不拆元对，以绳缚之，力将铁锉子锉之， 旋取用，勿令风犯，锉未尽处，须三重纸裹，恐力散也。锉得了即背风头重筛过，然后入药 中用
译文：雷公说：凡是使用有神力的羚羊角，这种神羊角长度有二十四节，内部有天然形成的木质核心，这角具有神力，可以抵得上千头牛的力气。凡是炮制加工时，不要让它们单独使用，否则不再有效，必须保留完整的一对，用绳子捆绑好，用力用铁锉锉削，随时取用，不要让风吹袭，未锉尽的部分，需要用三层纸包裹，恐怕药力会散失。锉好后立即背对风向重重地筛过，然后入药中使用。
Gan Long (Dragon Bone, Fossilized Mammal Bone) tastes sweet, is neutral in nature and non-toxic, and enters the Kidney Meridian. It primarily treats seminal emission and involuntary discharge in men, metrorrhagia and leukorrhea in women, stops intestinal wind-induced bleeding, and treats persistent diarrhea and dysentery. Those possessing all five colors are considered superior. Its teeth are used to treat fright, epilepsy, and mania. Gan Long is incompatible with Dry Lacquer (Gan Qi), Shu Pepper (Shu Jiao), Li Shi, and Gypsum Fibrosum (Shi Gao).
Commentary: The *Classic* states that the Kidneys govern bones; thus, Gan Long uniquely enters this meridian. Observing its ability to adhere to the tongue, it is evident that its astringent properties are predominant, hence its efficacy in treating seminal emission and similar conditions. The medical classics state: "Astringents can resolve prolapse and leakage." This refers to such cases.
Hu Gu (Tiger Bone) tastes pungent, is slightly hot in nature and non-toxic, and enters the Kidney Meridian. It primarily treats pathogenic factors, ghostly affections (Gui Zhu), and toxic wind causing spasms and tightness of the sinews and bones. It should be used after roasting with butter. Hu Gu is incompatible with Dry Lacquer (Gan Qi), Shu Pepper (Shu Jiao), and Magnetitum (Ci Shi).
Commentary: Hu Gu enters the Kidney Meridian because the Kidneys govern bones. Why does it treat toxic wind within the bones? The *I Ching* says: "Wind follows the tiger." Wind belongs to Wood; the Tiger belongs to Metal. Since Wood is controlled by Metal, how can it not follow?
Lei Gong states: When using Hu Jing (Tiger Eye), one must inquire with hunters whether the eyes are from male or female, old or young tigers, and whether they were killed by hunting. Eyes from tigers that died from poisoned arrows must not be used, as they can harm humans. When using Hu Jing, soak them overnight in grass sheep blood, drain them, and dry them over a mild fire. Pound them into powder, and mix them with other prepared herbs when ready for use.
Xi Jiao (Rhinoceros Horn) tastes bitter, sour, and salty, is cold in nature and non-toxic, and enters the Heart and Liver meridians. It primarily treats various toxins, gu affections, ghostly pathogenic factors, cold damage, epidemic febrile diseases, irritability, mania, blood heat in smallpox and measles, carbuncles, sores, and swelling. It clears the Heart, calms the Liver, brightens the eyes, and settles fright. Pregnant women should avoid taking it. Superior quality is characterized by fine texture, black color, brightness, smoothness, and lubricity. The tip of the horn is preferred as it possesses complete efficacy. Pine Resin (Song Zhi) serves as an guiding herb. Xi Jiao is adverse to Lei Wan and salt should be avoided.
Commentary: Xi Jiao is bitter and cold; originally entering the Heart to drain fire, it also enters the Liver because if Heart Fire does not flare up recklessly, Lung Metal can properly control Liver Wood. Zhu Danxi said: "It belongs to Yang and moves vigorously, even more so than other horns." It is commonly used after smallpox to dissipate residual toxins. However, if given to patients who are not suffering from residual toxins but have Blood deficiency, leading to dryness and fever, the disaster will be boundless.
Lei Gong states: Do not use Nu Xi Jiao, Bing Shui Xi, Luan Zi Xi, or Wu Run Xi. Only select those that are black, wrinkled, cracked, smooth, and lustrous as top grade. During processing, file the shavings into a mortar, pound until fine, then grind ten thousand times in the mortar before use. Pregnant women must not take it, as it can dissolve fetal qi. Salt should be avoided.
Ling Yang Jiao (Antelope Horn) tastes bitter and salty, is cold in nature and non-toxic, and enters the Liver Meridian. It primarily treats heat in the skin and muscles from cold damage, warm pathogens lurking between bones, inauspicious pathogenic factors, frightful dreams, mania, restless mind, sudden high fever and convulsions in children, and postpartum敗血 (decayed blood) rushing to the Heart. It clears the Heart, detoxifies, brightens the eyes, and benefits Qi. Burnt to ash, it also treats dysphagia. Horns with deep, inverted trigram-like marks are authentic.
Commentary: Zhu Danxi said: "Antelopes belong to Wood and are suitable for entering the Jueyin [Liver] Meridian. When Wood is balanced, wind and fire syndromes cannot invade."
Lei Gong states: When using Shen Ling Yang Jiao (Divine Antelope Horn), note that it has twenty-four joints and contains a naturally formed wooden core inside. This horn possesses divine power, equivalent to that of a thousand oxen. During processing, do not use single horns alone, as they lose efficacy. Keep the original pair intact, bind them with rope, and file them with force using an iron file. Use immediately, avoiding exposure to wind. Unfiled portions must be wrapped in three layers of paper to prevent the loss of potency. After filing, sift heavily against the wind direction, then incorporate into medicinal preparations.
