（性善辟尘、扑尘水上、投胆米许、即开。）肉、补虚羸；掌，御风寒。又益气力。
外用，收敛金疮（金属利器造成的创伤），促进肌肉生长。
象肉发生壅肿时，用刀刺破它，半天就能愈合。治疗金疮不能愈合的情况，使用象皮的灰烬，也可以熬制成膏剂加入散剂中，是合成金疮的重要药物，也是促进肌肉生长的神丹。（将象皮烧成灰，与油调和敷于下疳患处，效果神奇。）
清泻心胃的大热。
味苦、酸、咸，性寒。能凉心泻肝，清泄胃中的大热，祛风利痰，辟邪解毒。治疗伤寒和时疫引起的发黄、发斑。（伤寒若攻下过早，热邪乘虚入胃则发斑；攻下过迟，热邪留滞胃中，也会发斑。）治疗吐血、便血，蓄血导致的发狂，痘疮黑陷，消散痈肿化脓，定惊明目。（李时珍说：五脏六腑都禀受胃气，风邪热毒必定先侵犯它们，饮食药物也必先入胃，犀角是精华聚集之处，属于足阳明胃经的药物，所以能入阳明经，解一切毒，疗治一切血证，以及惊狂、斑疹、痘疮等病症。抱朴子说：犀牛角吃百草的毒物及荆棘，所以能解毒，饮食中有毒物，用犀角搅拌，就会产生白色泡沫。段公路《北户录》说：凡是中了毒箭，用犀角刺入伤口，立刻痊愈。）犀角是大寒之性，如果不是大热证，不敢轻易服用。孕妇服用，会消损胎气。颜色乌黑且光润的为好，角尖的效果更佳。（鹿取鹿茸，犀取角尖，它们的精气都在这里。）现成的器物，多用于制剂，磨成汁液使用，或入丸散，锉细后，用纸包裹放在怀中，待其受热变软后捣碎，立刻就会碎裂。（欧阳修《归田录》说：人气能使粉犀发热。）以升麻为使药，忌食盐。（热利导致下鲜血，用犀角、地榆、生地各等分，研为末，蜜丸如弹子大，每次服一丸，用水一盏，煎至半盏，去渣温服。）
清泻热邪。
味苦，性寒。凉心平肝，明目，杀虫。治疗惊痫、五痔。（外涂可取效。）实热证适宜，体虚者应当禁忌。质地通明的为佳。（性质善于辟尘，扑在灰尘水上，投入少许胆米，水即分开。）犀牛肉，补益虚弱羸瘦；犀牛掌，抵御风寒。又能益气力。
Externally applied, it astringes metal wounds (traumas caused by metal weapons) and promotes muscle regeneration.
When the flesh of an elephant becomes swollen and congested, piercing it with a knife allows it to heal within half a day. To treat metal wounds that fail to close, use the ash of elephant skin; it can also be boiled into an ointment and added to powders. It is an essential medicine for healing metal wounds and a miraculous elixir for promoting muscle growth. (Burned to ash and mixed with oil, applied externally to chancre, it is highly effective.)
Clears away excessive heat in the Heart and Stomach.
Bitter, sour, salty, and cold in nature. It cools the Heart and drains the Liver, clears excessive heat in the Stomach, dispels wind and benefits phlegm, wards off evil pathogens, and detoxifies. It treats jaundice and macules/petechiae caused by Cold Damage (Shanghan) and seasonal epidemics. (If purgatives are used too early in Cold Damage, heat enters the Stomach through deficiency causing macules; if used too late, heat remains in the Stomach, also causing macules.) It treats hematemesis and hematochezia, mania due to blood stasis, blackened and depressed acne/variola, dissipates carbuncles and transforms pus, calms fright, and brightens the eyes. (Li Shizhen said: The five zang and six fu organs all receive qi from the Stomach. Wind pathogens and heat toxins must first affect them, and food and drugs must first enter the Stomach. Rhinoceros horn is where its essence gathers; it belongs to the Foot Yangming Stomach channel. Therefore, it can enter the Yangming channel, resolve all toxins, treat all blood disorders, and conditions such as fright, mania, macules, and variola. Baopuzi states: The rhinoceros eats the toxins of hundred herbs and thorns, thus it can detoxify. If food is toxic, stirring it with a horn produces white foam. Duan Gonglu's *Buhu Lu* states: Whenever one is wounded by a poisoned arrow, piercing the wound with a rhinoceros horn leads to immediate recovery.) Its nature is extremely cold. Unless there is excessive heat, one dare not take it lightly. Pregnant women taking it may abort the fetus. Those that are black and lustrous are superior, especially the tip of the horn. (For deer, the velvet antler is taken; for rhinoceros, the horn tip is taken, as their essence resides therein.) Ready-made artifacts are mostly used in preparations; grind into juice or add to pills and powders. Finely chopped, wrap in paper and place in the bosom; when warmed by body heat, pound it, and it will shatter immediately. (Ouyang Xiu's *Guotian Lu* mentions: Human breath heats powdered rhino horn.) Cimicifugae Rhizoma (Shengma) serves as the guiding herb. Avoid salt. (For bloody diarrhea due to heat, use equal parts Rhinoceros Cornu, Sanguisorbae Radix, and Rehmanniae Radix, grind into powder, make honey pills the size of a bullet, take one pill per dose, decoct with one cup of water until half remains, strain, and take warm.)
Clears heat.
Bitter and cold. Cools the Heart, pacifies the Liver, brightens the eyes, kills parasites. Treats epilepsy and five types of hemorrhoids. (Applied externally, it cures.) Suitable for excess-heat patterns; contraindicated for those with deficiency. Transparent quality is best. (Its nature is good at repelling dust; when thrown onto water with dust, adding a little gallstone rice causes the water to separate.) The meat tonifies weakness and emaciation; the palm resists wind and cold. It also supplements qi and strength.
