（《唐本草》）
【集解】恭曰∶枫柳出原州。叶似槐，茎赤根黄。子六月熟，绿色而细。剥取茎皮用。
时珍曰∶苏恭言枫柳有毒，出原州。陈藏器驳之，以为枫柳皮即今枫树皮，性涩能止水
痢。按∶《斗门方》言即今枫树上寄生，其叶亦可制粉霜，此说是也。若是枫树，则处处甚
多，何必专出原州耶？陈说误矣。枫皮见前枫香脂下。
皮
【气味】辛，大热，有毒。

【气味】苦，平，无毒。

（《别录》下品）
【释名】炭皮（《别录》）、良无极（《纲目》）
时珍曰∶占斯，《范汪方》谓之良无极，《刘涓子鬼遗方》谓之木占斯，盛称其功，而《别
录》一名炭皮，
【集解】《别录》曰∶占斯生太山山谷。采无时。
弘景曰∶李当之云∶是樟树上寄生，树大衔枝在肌肉。今人皆以胡桃皮为之，非是真
也。按∶《桐君采药录》云∶生上洛。是木皮，状如浓朴，色似桂白，其理一纵一横。今市
人皆削，乃似浓朴，而无正纵横理。不知此复是何物，莫测真假也。

在下者，当下脓血。其疮未坏及长服者，去败酱。一方加桂心。（《刘涓子鬼遗方》）
（出自《唐本草》）
【集解】苏恭说：枫柳产于原州。叶子像槐树叶，茎是红色的，根是黄色的。果实六月成熟，呈绿色且细小。剥取茎皮使用。
李时珍说：苏恭称枫柳有毒，产于原州。陈藏器反驳他，认为枫柳皮就是现在的枫树皮，性味涩，能止住水痢。按：《斗门方》说它实际上是生长在枫树上的寄生植物，其叶也可以用来制作粉霜，这种说法是正确的。如果是枫树本身，那么到处都很多，何必专门指出产于原州呢？陈藏器的说法是错误的。枫皮的内容见前文“枫香脂”条下。
【气味】辛味，大热，有毒。
【主治】风邪，龋齿痛（《唐本草》）。多年痛风疼痛难忍，长期治疗无效者。
将其细切焙干，用量不限，加入冰片、麝香浸泡在酒中经常服用，以喝醉为限度（《斗门方》）。
（出自《本草纲目》）
【气味】苦味，辛味，无毒。
【主治】小儿中蛊毒，腹部坚硬疼痛，面目青黄，消瘦如柴。取二两研成粉末，像喝茶一样冲服，每天四到五次（李时珍，《圣惠方》）。
（出自《本草纲目》）
【集解】李时珍说：这就是生长在柳树上的寄生植物。
【气味】苦味，平性，无毒。
【主治】膈气刺痛，捣汁服用一杯（李时珍）。
（出自《名医别录》下品）
【释名】炭皮（《名医别录》）、良无极（《本草纲目》）
李时珍说：占斯，在《范汪方》中称为良无极，在《刘涓子鬼遗方》中称为木占斯，极力称赞其功效，而《名医别录》中又名炭皮。
【集解】《名医别录》说：占斯生长于泰山山谷。采集没有固定时间。
陶弘景说：李当之说：这是生长在樟树上的寄生植物，树干很大，枝条嵌入肌肉中。现在人们都用胡桃皮来冒充，这不是真的。按：《桐君采药录》说：产于上洛。它是木皮，形状像厚朴，颜色像桂皮但偏白，纹理是一纵一横的。现在市场上的人把它削过之后，看起来像厚朴，但没有正确的纵横纹理。不知道这到底是什么东西，无法猜测真假。
【气味】苦味，温性，无毒。
孟诜说：辛味，平性，无毒。吴茱萸作为它的使药。
【主治】邪气引起的湿痹，寒热交替及疽疮，消除水液积聚和血瘀症，闭经不孕，小儿瘫痪不能行走，各种恶疮痈肿，停止腹痛，使妇女能够生育（《名医别录》）。主治脾热，洗手……
【附方】新方一则。
木占斯散：治疗发背、肠痈疽痔，妇人乳痈，各种产后症瘕，没有不治愈的。
服用后肿胀消退、疼痛停止、脓液消失，已经溃破的就会早日痊愈。木占斯、甘草（炙）、厚朴（炙）、细辛、栝蒌、防风、干姜、人参、桔梗、败酱各一两。研成散剂。用酒送服一方寸匕，白天七次，晚上四次，越多越好。此药咽下后，应当感觉流入疮口中，使其化为水。对于灸后未发泡、未败坏腐烂的痈疽，尤其适合服用。内痈在上部的，应当吐出脓血；在下部的，应当排出脓血。如果疮口未坏以及长期服用者，去掉败酱。另一方案加桂心。（《刘涓子鬼遗方》）
(From *Tang Bencao*)
[Collected Explanations] Su Gong stated: Fengliu originates from Yuanzhou. Its leaves resemble those of the locust tree, its stems are red, and its roots are yellow. The seeds ripen in June; they are green and slender. The bark of the stem is peeled for use.
Li Shizhen stated: Su Gong claimed that Fengliu is toxic and originates from Yuanzhou. Chen Cangqi refuted this, asserting that the bark of Fengliu is actually the bark of the current maple tree (*Acer* species), which has an astringent nature and can stop watery dysentery. According to my analysis: *Doumen Fang* states that it is actually an epiphyte growing on the maple tree, and its leaves can also be used to make powder resembling frost. This view is correct. If it were the maple tree itself, it would be abundant everywhere, so why specify that it originates exclusively from Yuanzhou? Therefore, Chen's statement is erroneous. The content regarding Maple Bark can be found under the entry for "Cinnamomum Camphora Resin" (Fengxiang Zhi) mentioned earlier.
[Bitterness and Heat Properties] Pungent, extremely hot, and toxic.
[Indications] Wind pathogens, toothache due to dental caries (*Tang Bencao*). Intractable gout persisting for years, unresponsive to long-term treatment.
Finely chop and roast without limiting the quantity, soak in wine with Borneol (Bingpian) and Musk (Shexiang), and take regularly until intoxication is achieved (*Doumen Fang*).
(From *Bencao Gangmu*)
[Bitterness and Heat Properties] Bitter, pungent, non-toxic.
[Indications] Infant poisoning by Gu toxin, characterized by hard abdominal pain, bluish-yellow complexion, and emaciation resembling protruding bones. Take two liang, grind into powder, and administer like tea, four to five times daily (Li Shizhen, *Shenghui Fang*).
(From *Bencao Gangmu*)
[Collected Explanations] Li Shizhen stated: This refers to the parasite growing on willow trees.
[Bitterness and Heat Properties] Bitter, neutral, non-toxic.
[Indications] Stabbing pain due to Qi stagnation in the diaphragm. Crush and extract juice, taking one cup (Li Shizhen).
(From *Mingyi Bielu*, Lower Grade)
[Names] Tanpi (*Mingyi Bielu*), Liangwuji (*Bencao Gangmu*).
Li Shizhen stated: Zhansi was called Liangwuji in *Fan Wang Fang* and Muzhansi in *Liu Juanzi Guiyi Fang*. Its efficacy was highly praised, while *Mingyi Bielu* also lists it as Tanpi.
[Collected Explanations] *Mingyi Bielu* states: Zhansi grows in the valleys of Mount Tai. It can be harvested at any time.
Tao Hongjing stated: Li Dangzhi said: It is a parasite growing on camphor trees, where large branches embed into the muscle. Nowadays, people use walnut husks to substitute it, which is not authentic. According to my analysis: *Tongjun Caiyao Lu* states: It grows in Shangluo. It is tree bark, resembling Magnolia Officinalis Bark (Houpo) in shape, white like Cinnamon Twig (Guizhi) in color, with longitudinal and transverse grain patterns. However, merchants today shave it down so it resembles Houpo but lacks the distinct longitudinal and transverse grain. I do not know what this substance is and cannot discern its authenticity.
[Bitterness and Heat Properties] Bitter, warm, non-toxic.
Meng Shen stated: Pungent, neutral, non-toxic. Evodia Fruit (Zhuyu) serves as its guiding herb.
[Indications] Pathogenic factors causing damp bi-syndrome, alternating chills and fever, ulcers and sores, eliminating fluid accumulation and blood stasis, amenorrhea leading to infertility, infantile paralysis preventing walking, various malignant sores and abscesses, stopping abdominal pain, and enabling women to conceive (*Mingyi Bielu*). Treats spleen heat, washing hands...
[Attached Prescriptions] One new prescription.
Muzhansi Powder: Treats back carbuncles, intestinal abscesses, hemorrhoids, breast abscesses in women, and all postpartum masses and tumors, with no case left untreated.
After administration, swelling subsides, pain ceases, and pus dissipates; already ulcerated cases heal early. Muzhansi, Licorice Root (Gancao) (roasted), Magnolia Officinalis Bark (Houpo) (roasted), Asarum (Xixin), Trichosanthes Fruit (Gualou), Saposhnikovia Root (Fangfeng), Dried Ginger (Ganjiang), Ginseng Root (Renshen), Platycodon Root (Jiegeng), Patrinia Root (Baijiang) each one liang. Grind into powder. Administer one fangcun bi with wine, seven times during the day and four times at night; more is better. Upon swallowing, one should feel the medicine flowing into the sore, liquefying it. For carbuncles and sores that have been moxibusted but not yet blistered or necrotic, this is especially suitable. For internal abscesses located upper, pus and blood should be vomited; if lower, pus and blood should be purged. For sores not yet necrotic or for long-term use, remove Patrinia Root. Another formula adds Cinnamon Heart (Guixin) (*Liu Juanzi Guiyi Fang*).
