（出自《唐本草》）
【校正】并入《开宝重定本草·拾遗》中的“五毒草”。
【释名】赤薜荔（《本草纲目》）、五毒草（《开宝重定本草·拾遗》）、麦（《嘉祐补注神农本草图经》）。
李时珍说：并未详细考证。
【集解】苏恭说：各地山谷都有生长。藤蔓状生长，叶子像萝藦。根皮呈赤黑色，肉质呈黄红色。二月、八月采集根部，晒干。
苏颂说：据说到处都有，如今只有华山有生长。春夏季长出苗茎，化作藤蔓缠绕在草木之上，茎秆为红色。叶子青色，形状像荞麦叶。七月开出白色花朵，也像荞麦花。结出青色的果实。根部像菝葜，皮紫红色，肉质黄红色，八月采集根部，晒干收藏。
陈藏器说：五毒草生长在江东的平地上。花和叶都像荞麦。根部紧硬，像狗脊。也叫蛇衔，名称相同但实物不同。
李时珍说：五毒草就是赤地利，现在将它们合并为一类。
根
【修治】雷敩说：凡是采得后切成细段，用蓝叶连同根部一起放入生绢袋中盛装，蒸一个时辰（约两小时），去掉蓝叶，晒干使用。
【气味】味苦，性平，无毒。
陈藏器说：味酸，性平。能伏制丹砂（即与丹砂配伍可抑制其毒性或改变其性质）。
【主治】治疗赤白冷热各种痢疾，止血破血，治疗带下赤白，促进肌肉生长（《唐本草》）。主治痈疽恶疮毒肿，赤白游疹（一种皮肤红肿蔓延的疾病），虫咬、蚕咬、蛇咬、犬咬，都用醋磨碎外敷，也可以捣烂茎叶外敷。担心毒素进入腹内，煮汁饮用（陈藏器）。
【发明】李时珍说：唐代张文仲《备急方》中，治疗青、赤、黄、白等各种痢疾的鹿茸丸方剂中使用了它。那么它的功效擅长于凉血解毒，就可以知道了。
【附方】旧方二首。小儿热疮，全身面部都有，像火烧一样：用赤地利粉末，扑撒患处。（《外台秘要》）火疮消除疤痕：用赤地利粉末，用油调匀涂抹。（《太平圣惠方》）
(From *Tang Bencao*)
[Correction] Merged into "Wudu Cao" (Five-Poison Herb) in the *Shiyi* (Supplementary Material) section.
[Names] Chibili (Red Pothos; *Bencao Gangmu*), Wudu Cao (Five-Poison Herb; *Shiyi*), Mai (*Tujing*).
Li Shizhen stated: The details were not thoroughly investigated.
[Collection and Explanation] Su Gong said: It grows in valleys everywhere. It is a vine, with leaves resembling those of *Metaplexis japonica* (Luoli). The root bark is dark red-black, and the flesh is yellow-red. The roots are harvested in February and August and dried in the sun.
Su Song said: It is said to be found everywhere, but currently only grows on Mount Hua. In spring and summer, shoots emerge, forming vines that wrap around trees and grass, with reddish stems. The leaves are green, resembling buckwheat leaves. In July, white flowers bloom, similar to buckwheat flowers. It bears green seeds. The roots resemble those of *Smilax* (Baqia), with purple-red bark and yellow-red flesh. The roots are harvested in August, dried, and stored.
Chen Cangqi said: Wudu Cao grows in the flatlands of Jiangdong. Its flowers and leaves resemble buckwheat. The roots are tight and hard, resembling *Polystichum setiferum* (Gouji). It is also called She Xian (Snake Tendon); although the name is the same, the substance is different.
Li Shizhen said: Wudu Cao is identical to Chidili; they are now merged into one entry.
Root
[Processing] Lei Xiao said: Upon harvesting, cut into fine segments. Place together with Indigofera leaves and roots into a raw silk bag. Steam for one Fushi (a traditional Chinese time unit, approx. 2 hours). Remove the Indigofera leaves and dry for use.
[Flavor and Property] Bitter, neutral, non-toxic.
Chen Cangqi said: Sour, neutral. Can mitigate the effects of Cinnabar (Dansha).
[Therapeutic Actions] Treats various types of dysentery (red, white, cold, and hot); stops bleeding and breaks blood stasis; treats leukorrhea (red and white discharge); promotes tissue regeneration (*Tang Bencao*). Treats carbuncles, malignant sores, toxic swellings, erysipelas (Chi Bai You Zhen), and bites from insects, silkworms, snakes, and dogs. Apply using vinegar grinding or external application; alternatively, crush stems and leaves for external application. If concerned about toxins entering the abdomen, boil the juice and drink it (Chen Cangqi).
[Innovation/Analysis] Li Shizhen said: In Zhang Wenzhong's *Beiji Fang* (Emergency Formulas) from the Tang Dynasty, it is used in the formula for Lurong Wan (Deer Antler Pill) to treat various types of dysentery (green, red, yellow, white). Thus, its efficacy lies in cooling blood and detoxifying, which can be understood.
[Attached Formulas] Two old formulas. For pediatric heat sores appearing all over the body and face, resembling burns: Apply powder of Chidili externally (*Waitai Mi Yao*). For fire burns to eliminate scars: Mix powder of Chidili with oil and apply topically (*Taiping Shenghui Fang*).
