气味苦、酸、咸、寒，无毒。主百毒蛊疰、邪鬼瘴气，解钩吻、鸩羽、蛇毒，除邪，
不迷惑魇寐。久服轻身。
陈修园曰∶犀角气寒，禀水之气也；味苦酸咸无毒，得木火水之味也。主百毒蛊疰、邪
鬼瘴
气者，以犀为灵异之兽，借其灵气以辟邪也。解钩吻、鸩羽、蛇毒者，以牛属土而犀居水，
得水土之精，毒物投水土中而俱化也。不迷惑魇寐、轻身者，言水火既济之效也。今人取治
血症，与经旨不合。
气味咸、寒，无毒。主明目，益气，起阴，去恶血，注下。辟蛊毒，恶鬼不祥，常
不魇寐。（俗称羚羊）
【参】羚羊角气寒味咸无毒，入肾与膀胱二经。主明目者，咸寒以补水，水足则目明也。
益
气者，水能化气也。起阴者，阴器为宗筋而属于肝，肝为木，木得烈日而萎，得雨露而挺也
。味咸则破血，故主去恶血。气寒则清热，故止注下也。蛊毒为湿热之毒也，咸寒可以除之
。辟恶鬼不祥、常不魇寐梦者，夸其灵异通神之妙也。
气味甘、温，无毒。主漏下恶血，寒热，惊痫，益气，强志，生齿不老。
陈修园曰∶鹿为仙兽而多寿，其卧则口鼻对尾闾以通督脉；督脉为通身骨节之主，肾主
骨，
故又能补肾。肾得其补，则志强而齿固，以志藏于肾，齿为骨余也。督得其补，则大气升举
，恶血不漏，以督脉为阳气之总督也。然角中皆血所贯，冲为血海，其大补冲脉可知也。凡
惊痫之病，皆挟冲脉而作，阴气虚不能宁谧于内，则附阳而上升，故上热而下寒。阳气虚不
能周卫于身，则随阴而下陷，故下热而上寒；鹿茸入冲脉，而大补其血，所以能治寒热惊痫
也。至于长而为角，《别录》谓其主恶疮，逐恶气。以一点胚血，发泄已尽，只有拓毒消散
之功也。
【犀角】
气味：苦、酸、咸，寒性，无毒。主治各种毒物、蛊毒、疰气（一种具有传染性的痨病）、邪祟鬼魅及瘴气；能解除钩吻、鸩鸟羽毛、蛇类的毒性；祛除邪气，使人不致在睡眠中受到迷惑或惊魇。长期服用可使身体轻盈。
陈修园说：犀角气寒，禀受了水的性质；味道苦、酸、咸且无毒，具备了木、火、水三行的味道特性。主治百毒、蛊疰、邪鬼瘴气的，是因为犀牛是灵异之兽，借助它的灵气来辟除邪祟。能解钩吻、鸩羽、蛇毒的，是因为牛属土而犀居水中，获得了水土的精气，毒物落入水土之中便能随之化解。不迷惑、不惊魇、身体轻盈的，说的是水火既济的功效。现在的人用它来治疗血症，与经典的本意不符。
【羚羊角】
气味：咸，寒性，无毒。主治明目，益气，起阴（提升阴气），去除恶血，止住泄泻。辟除蛊毒，驱避恶鬼不祥，常不做噩梦惊魇。（俗称羚羊）
【参考注释】羚羊角气寒味咸无毒，入肾经和膀胱经。主治明目的，是因为咸寒可以滋补肾水，水充足则眼睛明亮。益气的，是因为水能化生为气。起阴的，是因为阴器属于宗筋而归属于肝，肝属木，树木遇到烈日就会枯萎，遇到雨露就会挺立。味道咸能破血，所以主治去除恶血。气寒能清热，所以止住泄泻。蛊毒是湿热之毒，咸寒之性可以清除它。辟除恶鬼不祥、常不做噩梦惊魇的，是夸大其灵异通神的妙处。
【鹿茸】
气味：甘，温性，无毒。主治漏下恶血，寒热往来，惊痫（惊风癫痫），益气，增强意志，使牙齿生长不老。
陈修园说：鹿是仙兽且多寿，它睡觉时口鼻对着尾闾以通达督脉；督脉是全身骨节的主宰，肾主骨，所以又能补肾。肾得到补益，则意志坚强而牙齿坚固，因为志藏于肾，牙齿是骨的余绪。督脉得到补益，则大气升举，恶血不漏，因为督脉是阳气的总纲。然而角中都是血液贯穿，冲脉为血海，可知它能大补冲脉。凡是惊痫这类疾病，都挟带冲脉发作，阴气虚弱不能在内宁静安谧，就依附阳气而上升，所以上面热下面寒；阳气虚弱不能周遍护卫身体，就随阴气而下陷，所以下面热上面寒；鹿茸进入冲脉，大补其血，所以能治疗寒热惊痫。至于鹿长出了角，《别录》说它主治恶疮，驱逐恶气。因为一点胚胎之血已经发泄殆尽，只有开拓毒邪消散的作用了。
[Rhinoceros Horn]
Taste and Nature: Bitter, sour, salty; cold in nature; non-toxic. It is indicated for various toxins, Gu poison (parasitic disease), Zhu qi (infectious wasting disease), evil spirits, and miasma. It resolves the toxicity of Gouwen (Aconitum ferox), Zhen feathers (poisonous bird feathers), and snake venom. It expels pathogenic factors and prevents confusion or nightmares during sleep. Long-term use makes the body feel light.
Chen Xiuyuan stated: Rhinoceros horn has a cold nature, inheriting the Qi of Water. Its bitter, sour, and salty taste without toxicity corresponds to the flavors of Wood, Fire, and Water. Its ability to treat various toxins, Gu poison, Zhu qi, evil spirits, and miasma stems from the rhinoceros being a spiritual beast; its spiritual energy is borrowed to repel evil. Its ability to resolve specific venoms arises because cattle belong to Earth while rhinos dwell in Water, obtaining the essence of both Earth and Water; thus, when toxic substances enter Earth and Water, they are transformed and neutralized. The effects of preventing confusion, nightmares, and making the body light reflect the efficacy of the intersection of Water and Fire (Shui Huo Ji Ji). Currently, people use it to treat blood disorders, which does not align with the original intent of the classic texts.
[Antelope Horn]
Taste and Nature: Salty; cold in nature; non-toxic. It improves vision, benefits Qi, raises Yin, removes stagnant blood, and stops diarrhea. It repels Gu poison and evil omens, ensuring frequent absence of nightmares. (Commonly known as Antelope)
[Reference Annotation] Antelope horn has a cold nature and salty taste, entering the Kidney and Bladder meridians. Its indication for improving vision is due to its salty and cold nature nourishing Kidney Water; sufficient Water clarifies the eyes. Its benefit to Qi arises because Water can transform into Qi. Its ability to raise Yin relates to the fact that the genitalia belong to the Sinews (Zong Jin) and are governed by the Liver; the Liver belongs to Wood, and Wood withers under the scorching sun but stands erect under rain and dew. The salty taste breaks blood, hence it treats the removal of stagnant blood. The cold nature clears heat, hence it stops diarrhea. Gu poison is a toxin of damp-heat, which can be eliminated by salty and cold properties. The claims of repelling evil omens and preventing nightmares exaggerate its miraculous spiritual communication.
[Deer Antler Velvet]
Taste and Nature: Sweet; warm in nature; non-toxic. It treats leukorrhea with dark blood, alternating chills and fever, convulsions and epilepsy, benefits Qi, strengthens willpower, promotes tooth growth, and prevents aging.
Chen Xiuyuan stated: The deer is an immortal beast with longevity. When lying down, its mouth and nose face the Weilu point to connect with the Du Mai (Governing Vessel); the Du Mai is the master of all bone joints. Since the Kidneys govern bones, the deer also tonifies the Kidneys. When the Kidneys are tonified, willpower becomes strong and teeth become firm, because Will (Zhi) resides in the Kidneys, and teeth are the surplus of bones. When the Du Mai is tonified, the Great Qi rises, and dark blood does not leak, because the Du Mai is the commander of Yang Qi. However, the antler is penetrated by blood, and the Chong Mai (Penetrating Vessel) is the Sea of Blood; thus, it is known to greatly tonify the Chong Mai. Diseases such as convulsions and epilepsy always arise with the Chong Mai. When Yin Qi is deficient and cannot remain tranquil internally, it attaches to Yang Qi and ascends, resulting in upper heat and lower cold. When Yang Qi is deficient and cannot circulate to protect the body, it sinks with Yin Qi, resulting in lower heat and upper cold. Deer antler velvet enters the Chong Mai and greatly tonifies blood, thereby treating alternating chills, fever, convulsions, and epilepsy. As for the antler growing later, the *Bie Lu* states it treats malignant sores and expels evil Qi. Since the embryonic blood has been fully exhausted, it only possesses the function of dispersing toxins.
