秦地、陇地、龙地、蜀地的山中都有羚羊。它的角细长而圆锐，长四五寸，多节，颜色带黄的为好。
羚羊、山羊（即山羊）、山驴这三种动物相似。羚羊像羊但毛色青，毛粗且角短小；似吴羊（一种羊），角长大；山驴身体像驴但长着羚羊的角，只是角大且节间稀疏平缓罢了。
味咸，气寒，入厥阴肝经非常迅速。（羊是火畜，而羚羊属木，同气相求。）同时也入手太阴肺经和手少阴心经。主治明目益气，起阴，安心气，定肝魄，治疗惊邪魇寐（梦魔）、癫痫狂乱，治疗一切热毒风攻注，以及湿风注毒潜伏在骨间，中风筋挛骨痛，去除恶血下注，以及热毒血气疝气，小儿突发高热惊搐，妇人产后恶血攻心导致的烦闷，子痫痉疾。
羚羊性情灵秀，筋骨之精汇聚于角，所以又能辟除邪恶，解诸毒，碎佛牙，烧烟能驱走蛇虺。（李时珍语）羚羊角有二十四节，内有天生木胎者，此角有神。因为节合二十四气而生木胎，宛如从甲乙相生，起阴之气以转生阳，所以能益气。（黄之颐语）
与犀角、丹砂、牛黄、琥珀、天竺金、金箔、茯神、远志、钩藤、竹沥同用，治疗惊邪魇寐，以及癫痫狂乱等病。与枸杞子、甘菊、决明子、谷精草、生地、五味子、黄柏、密蒙花、木贼、女贞子同用，治疗肝肾虚而有热，导致目昏生翳。
产后烦闷，汗出不识人，将羚羊角烧成末，用东流水送服方寸匕，未愈再服。
〔论〕 李时珍详细列举了羚角的五种功效，未能充分阐明其原理。要知道人与畜生的脏腑差异不大，角乃骨之余，而肾所合者为骨。《内经》说：肾在体为骨，在气为坚。羚角禀受骨中至坚之气，《本经》首先说它明目，紧接着说益气起阴，是因为肾虽为阴中之至阴，但坎卦中有离卦，实为肾气所在。阴阳若有一方偏颇，则肾气便不足。肾气不足，就不能将气输送到肝，而肝也不能为肾执行其化生功能。因此，此物具体现于肾，致用于肝。肝本是阴气具足以升发阳气，即由阳气具足以引导阴气。如李时珍所列的去翳、舒筋、安魂、散瘀、降火这五种功效的原理，应当就在这里。所谓益气起阴，确实是肾具备肝的形体；而所谓五种功效，则是肝反过来行使肾的功能。正因为此物在肝的体用上都具有金属性，所以成为厥阴经的要药。《内经》说：一阴为独使。厥阴的生化没有阻碍，而心肺脾都由此开始依托生成。
凡是肝心二经虚而有热的，适宜使用。无热的不宜使用。（陈实功语）入厥阴经伐生生之气，不宜久用，多用则有害。
〔修治〕 凡单用时不再有效，必须不拆开原来的角对，用绳子绑住，凿取后随即使用，不要让它接触风。凿未尽之处，需用纸重重包裹，恐怕药力散失。另一种说法是，严密包裹藏在怀中，取出后再捣碎，这样容易粉碎。
Antelope horn is found in the mountains of Qin, Long, and Shu regions. Its horn is slender, round, and sharp, measuring four to five cun in length, with many nodes; those with a yellowish hue are considered superior.
The antelope (Lingyang), goat (Shanyang, i.e., domestic goat), and wild donkey (Shanlü) are three similar animals. The antelope resembles a goat but has bluish-green fur, coarse hair, and short, small horns. It resembles the Wu sheep, having large, long horns. The Shanlü has the body of a donkey but possesses antelope-like horns, though its horns are larger and the nodes are sparse and widely spaced.
It tastes salty and is cold in nature. It enters the Jueyin Liver Meridian very rapidly. (Goats are fire-associated animals, whereas the antelope belongs to Wood; thus, they share similar Qi and seek each other.) It also enters the Hand Taiyin Lung Meridian and the Hand Shaoyin Heart Meridian. It primarily treats brightening the eyes, benefiting Qi, raising Yin, calming the mind Qi, stabilizing the Liver's Hun (Ethereal Soul), treating fright evil and sleep paralysis (Yanmei), epilepsy, and mania. It treats all types of heat-toxic wind attacks and infiltration, as well as damp-wind toxic pathogens lurking between the bones. It treats wind-stroke with tendon spasms and bone pain, removes bad blood flowing downward, and addresses heat-toxic blood qi and hernia. It treats sudden fever and convulsions in children, and postpartum restlessness caused by bad blood attacking the heart. It also treats eclampsia and tetanus.
The antelope is spiritually agile, and the essence of its tendons and bones concentrates in its horn. Therefore, it can also ward off evil spirits, resolve various toxins, crush Buddha's teeth, and smoke from burning it can drive away snakes and vipers. (Li Shizhen) Antelope horns have twenty-four nodes. Those containing a naturally formed "wood embryo" within are considered divine. Because the nodes correspond to the twenty-four solar terms and generate wood, resembling the progression from Jia to Yi, the Qi that raises Yin transforms into generating Yang, thereby benefiting Qi. (Huang Zhiyi)
Combined with Rhinoceros Horn (Xijiao), Cinnabar (Dansha), Calculus Bovis (Niuhuang), Amber (Hupo), Tiantu Jin, Gold Leaf (Jinbo), Poria (Fushen), Polygala Root (Yuanzhi), Uncaria (Gouteng), and Bamboo Sap (Zhuli), it treats fright evil, sleep paralysis, epilepsy, and mania. Combined with Goji Berry (Qizi), Chrysanthemum (Ganju), Cassia Seed (Juemingzi), Eyebane (Gujingcao), Rehmannia Root (Shengdi), Schisandra Fruit (Wuweizi), Phellodendron Bark (Huangbai), Dysosma (Mimenghua), Equisetum (Muzei), and Privet Fruit (Nvzhen), it treats dim vision and corneal opacity caused by deficiency with heat in the Liver and Kidney.
For postpartum restlessness, sweating, and confusion/unconsciousness, burn Antelope Horn to ash, take one cubic inch dose with water from the eastern flow. If not cured, administer again.
For miscarriage with abdominal pain and continuous bleeding, burn three qian of Antelope Horn to ash, and take with Doulin Wine (wine infused with fermented soybeans).
[Discussion] Li Shizhen enumerated five merits of Antelope Horn but failed to fully explain their underlying principles. One must understand that the viscera of humans and beasts are not significantly different. Horns are the surplus of bone, and the Kidney governs bone. The Classics state: "The Kidney manifests in the body as bone, and in Qi as firmness." Antelope Horn inherits the utmost firmness of bone. The *Shennong Ben Cao Jing* first mentions brightening the eyes, followed immediately by benefiting Qi and raising Yin. This is because although the Kidney is the ultimate Yin within Yin, the Kan trigram contains Li, representing Kidney Qi. If Yin and Yang are imbalanced, Kidney Qi becomes insufficient. Insufficient Kidney Qi cannot transmit Qi to the Liver, and the Liver cannot execute its transformative functions for the Kidney. Thus, this substance embodies the Kidney and exerts effects on the Liver. The Liver, abundant in Yin, ascends Yang; conversely, abundant Yang guides Yin. The reasons for the five effects listed by Li Shizhen—clearing turbidity, relaxing sinews, calming the soul, dispersing stasis, and descending fire—lie herein. To benefit Qi and raise Yin is indeed the Kidney possessing the form of the Liver; while the five effects represent the Liver executing the function of the Kidney. Since this substance possesses Metal attributes in both the form and function of the Liver, it is a crucial herb for the Jueyin Meridian. The Classics state: "One Yin acts as a sole messenger." The generation and transformation of Jueyin face no obstruction, allowing the Heart, Lungs, and Spleen to find their origin here.
It is suitable for cases of deficiency with heat in the Liver and Heart meridians. It should not be used if there is no heat. (Chen Shigong) Entering the Jueyin Meridian to suppress the vital generating Qi, it should not be used for a long time or in large doses.
[Processing] When used alone, it may lose efficacy. It must not be separated from its original pair. Tie it with rope, chisel off pieces, and use immediately. Avoid exposure to wind. For unused portions, wrap them tightly in paper to prevent the loss of potency. Another method suggests keeping it tightly wrapped inside one's clothes to warm it, then crushing it, which makes it easier to pulverize.
