气味甘平，无毒。主治心腹鬼疰，精物老魅，咳逆，泄痢脓血，女子漏下，症瘕坚结
，小儿热气惊痫。
（晋地川谷及大山山岩，水岸土穴之中多有死龙之骨，今梁益、巴中、河东州郡山穴、
水涯
间亦有之骨。有雌雄骨，细而纹广者，雌也。骨粗而纹狭者，雄也。入药取五色具而白地碎
纹，其质轻虚，舐之粘舌者为佳。黄白色者次之，黑色者下也。其质白重，而花纹不细者，
名石龙骨，不堪入药，其外更有齿角，功用与龙骨相等。）
鳞虫三百六十，而龙为之长，背有八十一鳞，具九九之数，上应东方七宿，得冬月蛰藏
之精
，从泉下而上腾于天，乃从阴出阳，自下而上之药也。主治心腹鬼疰、精物老魅者，水中天
气，上交于阳，则心腹和平，而鬼疰精魅之阴类自消矣。咳逆者，天气不降也。泄痢脓血者
，土气不藏也。女子漏下者，水气不升也。龙骨启泉下之水精，从地土而上腾于天，则阴阳
交会。上下相和，故咳逆、泄痢漏下，皆可治也。土气内藏，则症瘕坚结自除，水气上升，
则小儿热气惊痫自散，不言久服，或简脱也。
气味甘温，无毒。主治漏下恶血，寒热，惊痫，益气，强志，发齿，不老。（《本经
》以白胶入上品，鹿茸入中品，今定俱入上品。）
（鹿游处山林，孕六月而生，性喜食龟，能别良草，卧则口鼻对尾闾，以通督脉。凡含
血之
物，肉最易长，筋次之，骨最难长。故人年二十骨髓方坚，唯麋鹿之角，自生至坚，无两月
之久，大者至二十余斤，计一日夜须生数两。凡骨之生无速于此，故能补骨血，益精髓。又
，头者，诸阳之会，上钟于茸，故能助阳。凡用必须鹿茸，今麋鹿并用，不可不别。）
鹿性纯阳，息通督脉，茸乃骨精之余，从阴透顶，气味甘温，有火土相生之义。主治漏
下恶
血着，土气虚寒，则恶血下漏。鹿茸禀火气而温土，从阴出阳，下者举之，而恶血不漏矣。
寒热惊痫者，心为阳中之太阳，阳虚则寒热。心为君主而藏神，神虚则惊痫。鹿茸阳刚渐长
，心神充足，而寒热惊痫自除矣。益气强志者，益肾脏之气，强肾藏之志也。生齿不老者，
齿为骨之余，从其类而补之，则肾精日益，故不老。
【龙骨】
气味甘平，无毒。主治心腹鬼疰（指邪气侵入人体，游移不定，如鬼魅附着般的病症），精物老魅（指妖邪精怪作祟），咳逆（咳嗽气逆），泄痢脓血（腹泻痢疾伴有脓血），女子漏下（妇女非经期阴道持续出血），症瘕坚结（腹部结块坚硬不移），小儿热气惊痫（小儿因热邪引起的惊厥癫痫）。
（在晋地的川谷及大山的山岩、水岸土穴中，多有死龙之骨；如今梁州、益州、巴中、河东等州郡的山穴、水边也有这种骨头。有雌雄之分：骨细而纹路宽的是雌性；骨粗而纹路窄的是雄性。入药选取五色俱全且底色为白、带有碎纹的，其质地轻虚，舔之粘舌的为佳品。黄白色的次之，黑色的最差。如果质地白重，花纹不细的，称为石龙骨，不堪入药。此外还有牙齿和角，功效与龙骨相等。）
鳞虫三百六十种，龙是它们的领袖，背上有八十一片鳞甲，符合九九之数，上对应东方七宿星象，禀受冬季蛰伏收藏的精气，从泉水之下腾空而上至天空，是从阴出阳、自下而上的药物。主治心腹鬼疰、精物老魅，是因为水中天气上交于阳，则心腹平和，而属于阴类的鬼疰精魅自然消除。咳逆，是因为天气不降。泄痢脓血，是因为土气不藏。女子漏下，是因为水气不升。龙骨开启泉下的水精，从地土向上腾达于天，使阴阳交会，上下调和，所以咳逆、泄痢、漏下都可以治疗。土气内藏，则症瘕坚结自然消除；水气上升，则小儿热气惊痫自然消散。文中未提及久服，可能是简略脱漏所致。
【鹿茸】
气味甘温，无毒。主治漏下恶血（非经期出血且血色暗黑有瘀血），寒热（忽冷忽热），惊痫，益气，强志（增强意志/记忆力），发齿（促进牙齿生长），不老。（《神农本草经》将白胶列入上品，鹿茸列入中品，现在确定两者都列入上品。）
（鹿生活在山林中，怀孕六个月生产，性喜吃龟，能辨别好草，睡觉时口鼻对着尾闾穴，以通达督脉。凡是含血的生物，肉最容易长，筋其次，骨头最难长。所以人到了二十岁骨髓才坚固，只有麋鹿的角，从生到变硬，不到两个月时间，大的可达二十多斤，算起来一天一夜要长几两。凡是没有比这长得更快的骨头了，所以能补骨血，益精髓。另外，头是诸阳之会，精气汇聚于茸，所以能助阳。凡是使用必须用鹿茸，现在麋鹿并用，不可不加以区别。）
鹿性纯阳，气息通达督脉，茸是骨精之余，从阴处透顶而出，气味甘温，有火土相生的意义。主治漏下恶血，是因为土气虚寒，导致恶血下漏。鹿茸禀受火气而温煦脾土，从阴出阳，提升下陷之气，恶血就不漏了。寒热惊痫，是因为心为阳中之太阳，阳虚则出现寒热；心为君主而藏神，神虚则出现惊痫。鹿茸阳气刚健逐渐增长，心神充足，寒热惊痫自然消除。益气强志，是补充肾脏之气，强化肾所藏的志。生齿不老，是因为齿为骨之余，顺着同类来补益，肾精日益充盈，所以不老。
[Longgu (Dragon Bone)]
Taste and nature: Sweet, neutral. Non-toxic. Indications: Treats "Gui Zhu" (diseases caused by evil qi wandering in the body, resembling possession) in the heart and abdomen, afflictions by spirits or demons, cough with reverse flow of Qi (Ke Ni), dysentery with pus and blood, leukorrhea or metrorrhagia in women (Lou Xia), hard masses in the abdomen (Zheng Jia), and pediatric convulsive epilepsy due to heat pathogen.
(Dragon bones are found in the valleys and mountain rocks of Jin region, as well as in soil burrows near water banks; they are also present in the mountain caves and shores of Liangzhou, Yizhou, Bazhong, and Hedong commanderies. There are male and female bones: those that are fine with broad striations are female; those that are coarse with narrow striations are male. For medicinal use, select those with all five colors present, a white base, and fragmented patterns. The best quality is light, void-textured, and sticky when licked. Yellowish-white is secondary, and black is inferior. If the texture is white and heavy with non-fine patterns, it is called "Shi Longgu" (Stone Dragon Bone) and is unsuitable for medicine. Additionally, teeth and horns have efficacy equal to dragon bone.)
Among the 360 species of scaled creatures, the dragon is the leader. It has 81 scales on its back, corresponding to the number of 9x9, and aligns with the Seven Mansions of the East. It embodies the essence of winter hibernation and storage, rising from the springs below to the heavens. Thus, it is a herb that moves from Yin to Yang, ascending from below. It treats Gui Zhu and spirit afflictions in the heart and abdomen because the Qi of water ascends to interact with Yang, harmonizing the heart and abdomen, thereby eliminating the Yin-type pathogens like ghosts and demons. Cough with reverse flow occurs due to the failure of Heaven's Qi (Lung Qi) to descend. Dysentery with pus and blood results from the failure of Earth Qi (Spleen/Stomach Qi) to store. Metrorrhagia in women is due to the failure of Water Qi (Kidney Qi) to ascend. Longgu opens the Water Essence from the springs, allowing it to rise from the earth to the heavens, facilitating the intersection of Yin and Yang and harmony between upper and lower. Therefore, it treats cough, dysentery, and bleeding. When Earth Qi stores internally, abdominal masses resolve naturally; when Water Qi ascends, pediatric heat-induced convulsions dissipate. The text does not mention long-term use, likely due to textual omission.
[Lurong (Deer Antler Velvet)]
Taste and nature: Sweet, warm. Non-toxic. Indications: Treats metrorrhagia with foul blood, alternating chills and fever, convulsive epilepsy, tonifies Qi, strengthens willpower/memory, promotes tooth growth, and prevents aging. (The *Shennong Bencao Jing* listed Baijiao in the Superior Grade and Lurong in the Medium Grade; now both are classified in the Superior Grade.)
(Deer inhabit mountains and forests, gestating for six months before giving birth. They prefer eating turtles and can distinguish good herbs. When lying down, their mouth and nose face the Weilu point (DU-4) to connect with the Du Meridian. Among blood-containing organisms, flesh grows easiest, tendons second, and bones hardest. Humans do not achieve solid marrow until age twenty. However, deer antlers harden from growth to maturity in less than two months, with large ones weighing over twenty jin, growing several liang per day. No bone grows faster, so it can tonify bone blood and benefit essence and marrow. Furthermore, the head is the meeting place of all Yang meridians, and essence gathers in the velvet, thus assisting Yang. One must use Deer Antler Velvet specifically; currently, elk antlers are used interchangeably, which requires distinction.)
Deer nature is purely Yang, and its Qi connects with the Du Meridian. The velvet is the surplus of bone essence, emerging from Yin to the crown. Its taste is sweet and warm, embodying the generation of Fire generating Earth. It treats metrorrhagia with foul blood because deficiency-cold of Earth Qi causes foul blood to leak. Lurong inherits Fire Qi to warm Earth, moving from Yin to Yang, lifting sunken Qi, thus stopping the leakage. Alternating chills and fever occur because the Heart is the Supreme Yang within Yang; deficiency of Yang leads to chills and fever. The Heart is the Sovereign and houses the Shen (Spirit); deficiency of Shen leads to fright and epilepsy. As Lurong's Yang energy gradually increases, the Heart Spirit becomes sufficient, resolving chills, fever, fright, and epilepsy. Tonifying Qi and strengthening willpower refers to supplementing Kidney Qi and reinforcing the Will (Zhi) stored in the Kidneys. Promoting tooth growth and preventing aging occurs because teeth are the surplus of bones; tonifying according to similarity replenishes Kidney Essence daily, thus preventing aging.
