苦涩温，无毒。《素问》谓之麋衔，《唐本》曰鹿衔，《千金》曰鹿药草，言鹿
有疾，衔此草即瘥也。其叶大而面绿背紫者为真。苏恭言有大小二种。保升言叶似茺蔚，丛
生，有毛者，吴凤草也。
《本经》主风湿痹，历节痛，惊痫吐血，悸气贼风，鼠 痈肿。
发明 鹿衔《本经》专主风湿痹，历节痛，《素问》同泽术治酒风身热懈惰，汗出如浴
，恶风少气之病，亦取其能除痹着血脉之风湿也。又治惊痫悸气，吐咯诸血，以其能走胃与
肾肝血分，专理血中邪湿，而无留滞之患。近世治吐血、咯血用之，以其能温补冲督之精血
也。陕人名为鹿胞草，言鹿食此，即能成胎。其性温，补下元可知。今吴兴山中间亦产此。
每于初夏，群鹿引子衔食乃去，洵为确真无疑。采得晒干，一味浸酒最为有益。但性专助阳
，力能走散阴精，故藏器云∶妇人服之绝产无子，良有见乎此也。其子名延寿果，味微涩而
甘，惟秦地有之，不特有益于老人，而婴儿先天不足者尤为上药。惜乎，南方罕得也。
苦辛温，无毒。
《本经》主寒热瘰 ，鼠 ，头疮，破症散瘿结气，脚肿湿痹，轻身。
发明 夏枯草，《本经》专治寒热瘰 ，有补养厥阴血脉之功。以辛能散结，苦能除热
，而症结瘿气散矣。言轻身者，脚肿湿痹愈，而无重着之患也。佐以香附、甘草，治目珠疼
夜甚者，以其禀纯阳之气，而散阴中结滞之热也。又能解内热，缓肝火，从治之法，并治痘
后余毒，及肝热目赤者效。久服亦防伤胃，以善走厥阴助肝木之气耳。
薇衔：味苦涩，性温，无毒。《素问》称其为麋衔，《唐本草》称为鹿衔，《千金方》称为鹿药草，意思是鹿如果生病，衔取这种草病就会痊愈。它的叶子大而正面绿色、背面紫色的是真品。苏恭说有大、小两种。保升说叶子像茺蔚，丛生，有毛的，是吴凤草。
《神农本草经》主治风湿痹痛，历节痛，惊痫吐血，悸气贼风，鼠瘘痈肿。
发明：鹿衔，《本经》专门主治风湿痹痛，历节痛，《素问》中用泽术治疗酒风身热懈惰，汗出如浴，恶风少气的病证，也是取其能祛除血脉中滞留的风湿邪气。又治疗惊痫悸气，吐咯各种血液，因为它能走胃与肾肝血分，专门调理血中的邪湿，而没有留滞的祸患。近世治疗吐血、咯血使用它，是因为它能温补冲脉和督脉的精血。陕西人名为鹿胞草，说鹿吃了它，就能受孕成胎。它的性质温，可以知道它能补下元。现在吴兴山中间也出产这个。每当初夏，群鹿带领幼鹿衔食它就离开，确实是确凿真实无疑。采得晒干，单味药浸酒最为有益。但性质专门助阳，力量能走散阴精，所以藏器说：妇人服用它绝产无子，确实是有见地于此。它的子名叫延寿果，味道微涩而甘，只有秦地有之，不仅对老人有益，而且婴儿先天不足者尤为上品药物。可惜南方很少得到。
夏枯草：味苦辛，性温，无毒。
《神农本草经》主治寒热瘰疬，鼠瘘，头疮，破症散瘿结气，脚肿湿痹，轻身。
发明：夏枯草，《本经》专门治疗寒热瘰疬，有补养厥阴血脉的功效。因为辛能散结，苦能除热，而症结瘿气消散了。说轻身的，是因为脚肿湿痹好了，就没有重着的祸患了。佐以香附、甘草，治疗目珠疼夜间加重的，因为它禀受纯阳之气，而散阴中结滞的热邪。又能解内热，缓肝火，从治的方法，并治疗痘后余毒，以及肝热目赤者有效。久服也要防止伤胃，因为它善于走厥阴助肝木之气罢了。
**Wei Xian (Dentaria japonica / Lysimachia clethroides):** Bitter, astringent, warm, non-toxic. *Suwen* calls it Mi Xian; *Tang Bencao* calls it Lu Xian; *Qianjin Fang* calls it Lu Yao Cao, stating that if a deer is ill, chewing this herb will cure it. The true variety has large leaves with green upper surfaces and purple undersides. Su Gong mentions two types: large and small. Bao Sheng states the leaves resemble Chongwei (Leonurus japonicus), grow in clusters, and those with hairs are called Wu Feng Cao.
*Shennong Benjing* indicates it treats wind-damp bi syndrome, Li Jie pain (pain affecting multiple joints), fright-epilepsy, hematemesis, palpitations due to thief-wind, and shu lou (scrofula) and carbuncles.
**Invention:** Lu Xian, according to *Benjing*, specifically treats wind-damp bi syndrome and Li Jie pain. *Suwen* uses Ze Zhu (Atractylodes macrocephala combined with Cyperus rotundus) to treat jiu feng (alcohol-induced wind) characterized by body heat, lethargy, sweating like bathing, aversion to wind, and shortness of qi; this also relies on its ability to remove wind-damp pathogens lingering in the blood vessels. It also treats fright-epilepsy and palpitations, as well as various forms of vomiting or spitting blood, because it enters the stomach and the blood aspect of the Kidney and Liver, specifically regulating pathogenic dampness in the blood without causing stagnation. In recent times, it is used for hematemesis and hemoptysis because it can warm and tonify the essence and blood of the Chong and Du vessels. People in Shaanxi call it Lu Bao Cao, saying that when deer eat it, they become pregnant. Its warm nature indicates it tonifies the lower yuan (lower burner/origin). It is also produced in the mountains of Wuxing. Every early summer, herds of deer lead their young to chew and eat it before leaving, which is indeed authentic beyond doubt. After harvesting and sun-drying, steeping it alone in wine is most beneficial. However, its nature specifically aids yang, and its strength can disperse yin essence. Therefore, Zang Qi stated: "Women who take it will lose fertility and have no children," which is indeed insightful. Its seed is named Yan Shou Guo (Longevity Fruit), with a slightly astringent and sweet taste, found only in the Qin region. It is not only beneficial for the elderly but is especially a superior medicine for infants with congenital deficiency. Unfortunately, it is rarely obtained in the south.
**Xia Ku Cao (Prunella vulgaris):** Bitter, pungent, warm, non-toxic.
*Shennong Benjing* indicates it treats cold and heat luo li (scrofula), shu lou, head sores, breaks masses, dissipates ying (goiter) and stagnant qi, leg swelling with damp-bi, and lightens the body.
**Invention:** Xia Ku Cao, according to *Benjing*, specifically treats cold and heat luo li, possessing the function of nourishing the Jueyin (Liver/Pericardium) blood vessels. Because pungency can dissipate nodules and bitterness can clear heat, the mass and goiter stagnation are dispersed. The statement about "lightening the body" implies that once leg swelling and damp-bi are cured, the sensation of heaviness disappears. Combined with Xiang Fu (Cyperus rotundus) and Gan Cao (Glycyrrhiza uralensis), it treats eye pain that worsens at night, because it embodies pure yang qi and disperses heat stagnated within yin. It can also resolve internal heat, soothe liver fire, and through the method of contrary treatment, it is effective for residual toxins after smallpox/variolae and for liver heat causing red eyes. Long-term use requires caution to prevent stomach damage, as it readily enters the Jueyin channel to assist the qi of liver wood.
