则菜字下当补一莱字可解）。入药用近根皮，酒煎服取汗即愈。力弱者发战作吐，病亦愈。
戚孔昭云，木八角之须，乃麻黄，未知确否。
叶片形状与臭梧桐相同，但质地较薄且粗糙，气味也带有臭味。五月开花，花朵成簇，一个花蒂上开出百花，颜色为粉红色。
治疗痔疮和疔疮：《赤水元珠》记载：取苍耳、臭牡丹各一大把，捣烂，用刚打来的井水调服，泻下黑水后即可痊愈。
治疗各种痈疽：淳安的一位老中医说：使用臭牡丹的枝叶捣烂，敷在患处，立刻就能消散。
治疗脱肛：《秘方集验》记载：先用臭梧桐叶煎汤清洗，然后将浮萍草研成的粉末撒在上面，脱出的肛门就不会再脱出了。（应昌按语：这里的“梧桐”二字，怀疑是“牡丹”的讹误，否则这个方子应该列入臭梧桐的方剂之内，可惜无法找到原书进行校正。）
植株高两到三尺，叶子像木芙蓉，有八个角且有芒刺，靠近花蒂处的叶子如果有红色为佳。秋天开白色小花，细密成簇，药用部分取靠近根部的树皮。
唐代王周《金盘草诗注》记载：金盘草生长在甯江、巫山、南陵等地的林木中，它的根一年长出一节，人们采集服用，可以解毒。他的诗写道：“今年春天从南陵来，得到一种名叫金盘的草，金盘具有仁爱之性。生长在林木边缘，根部每年长出一节，吃它味道甘酸，当地风俗竞相采摘，用来防备急难，巴中的蛇虺毒，解开它就像滚动的弹丸一样快，巨大的叶子展开六个角，柔软的茎干分成长竿，摇曳着像绿色的玉石般鲜活，香气带着寒意，世人说在酷暑月份，这里仿佛有神物看护；上天产生这种植物于此，意图让百姓安康。”根据诗意，这似乎就是现在的草八角，其性质又能解除蛇毒。
（草八角）味苦、辛，性温，有毒。治疗麻痹风毒，跌打损伤导致的瘀血停滞积聚。其气猛悍，能开通壅塞，疼痛麻木立即停止，体虚者慎用。
《药鉴》记载：产于潜山、昌化的深山中，叶子角向上仰，颜色黄，独茎一叶，五六月开花，双朵成对，粉红色，向下垂，根圆而不长，俗名孩儿撑伞。
《百草镜》记载：草八角高一尺左右，根部长有疙瘩，独茎一叶，入秋开花，只有两朵相对，粉红色，又名红孩儿。结出的种子红色成对，像小孩一样。其根可以消毒，入药时，以得草本者为良。根治痈毒，其余功效同木八角。
按语：八角金盘有草木两种，木本的，其叶尖，角向上仰起像盘子状，叶背颜色黄，所以叫金盘；草本的，叶尖角不向上仰，叶背不黄，有细微区别。此药性热力猛，有毒，咀嚼味道发麻，即使是身体壮实的人也宜少用。服药后忌食鱼腥及猪、羊、牛、马等肉类，触犯这些食物会令人癫狂，唯有白菜菔（应昌按语：菜字怀疑是莱字的讹误，否则菜字下面应当补一个莱字才能解释通）。入药时用靠近根部的皮，酒煎服，出汗即愈。体力弱者会出现战栗呕吐，病也会好。
Stinky Peony (Chou Mudan)
The leaf shape is the same as that of *Firmiana simplex* (Chou Wutong), but thinner and rougher, with a similar foul odor. It flowers in clusters in May, with one pedicel bearing many flowers, pink in color.
Treatment for hemorrhoids and carbuncles: According to *Chishui Yuanzhu*: Take a large handful each of *Xanthium strumarium* (Cang'er) and Stinky Peony, pound them into a paste, mix with fresh well water, and take orally. Healing occurs after the discharge of black fluid.
Treatment for various sores and ulcers: An old physician from Chun'an stated: Pound the branches and leaves of Stinky Peony into a paste and apply it topically; it will dissipate immediately.
Treatment for rectal prolapse: According to *Mifang Jiyuan*: First wash with a decoction of *Firmiana simplex* (Chou Wutong) leaves, then sprinkle powdered *Lemna minor* (Fupingcao) on the area; the prolapse will cease. (Yingchang's note: The characters "Wutong" are suspected to be an error for "Mudan"; otherwise, this prescription should be listed among those for Chou Wutong. Unfortunately, the original text could not be verified.)
Grass Bajiao (Cao Bajiao)
The plant is two to three chi high. The leaves resemble those of *Hibiscus mutabilis* (Mu Furong), with eight angles and awns. Leaves near the pedicel with red coloration are preferred. It bears small white flowers in dense clusters in autumn. The medicinal part is the bark near the root.
Note on the Poem "Jinpan Cao" by Wang Zhou of the Tang Dynasty: Jinpan Cao grows in the forests of Ningjiang, Wushan, and Nanling. Its root produces one node per year. People harvest and consume it to detoxify. The poem states: "This spring I came from Nanling, obtaining a grass named Jinpan. Jinpan possesses a benevolent nature. It grows at the edge of the forest, its root forming one node annually. Eating it tastes sweet and sour. Local customs compete to gather it, to guard against emergencies. In Bazhong, snake venom is neutralized as easily as a rolling ball. Large leaves spread six angles, soft stems divide into long poles, swaying like living green jade, fragrant yet cold. The world says that in the hottest months, divine beings watch over it here. Heaven produced this plant here, intending to ensure the people's safety." Based on the poem's meaning, this appears to be the current Grass Bajiao, which also possesses the property of resolving snake venom.
Taste: Bitter, acrid. Nature: Warm. Toxicity: Toxic. Indications: Paralytic wind-toxin, blood stasis accumulation from trauma. Its qi is fierce and vigorous, capable of opening blockages, instantly relieving pain and numbness. Use with caution in patients with deficiency.
According to *Yaojian*: It originates from the deep mountains of Qianshan and Changhua. The leaf angles point upward, yellow in color. It has a single stem with one leaf. It flowers in pairs in May and June, pink and drooping. The root is round and not elongated. Common name: Child Holding an Umbrella.
According to *Baicao Jing*: Grass Bajiao is about one chi high. The root has tubercles. It has a single stem with one leaf. It flowers in autumn, with only two flowers facing each other, pink in color. Also known as Red Child. The seeds are red and paired, resembling children. The root can detoxify. For medicinal use, herbaceous varieties are superior. The root treats toxic sores; other effects are similar to Wood Bajiiao.
According to *Gezufang*: Nature is warm. Treats wind within the bones.
Note: There are two types of *Aralia chinensis* (Bajiao Jinpan): woody and herbaceous. The woody type has pointed leaves with angles pointing upward like a plate, and the leaf back is yellow, hence the name Jinpan. The herbaceous type has leaf angles that do not point upward, and the leaf back is not yellow; there is a slight difference. This medicine has strong heat and toxicity; chewing it causes numbness. Even robust individuals should use it sparingly. After taking the medicine, avoid fish, pork, mutton, beef, and horse meat. Violating this may cause mania. Only Chinese cabbage and radish (Yingchang's note: The character "Cai" is suspected to be an error for "Lai"; otherwise, the character "Lai" should be added after "Cai" to make sense). For medicinal use, use the bark near the root, decocted in wine. Sweating indicates cure. Those with weak constitution may experience tremors and vomiting, but the illness will also resolve.
Qi Kongzhao stated that the root hairs of Wood Bajiiao are *Ephedra sinica* (Mahuang), though the accuracy is uncertain.
