（宋《图经》）
【集解】颂曰∶生施州。苗高一尺以来，叶背紫，无花。土人采根用。
时珍曰∶湖湘水石处皆有之，名金盘藤。似醋筒草而叶小，背微紫。软茎引蔓似黄丝，
搓之即断，无汁可见。方士用以制汞。他处少有。醋筒草∶叶似木芙蓉而偏，茎空而脆，味
酸，开白花。广人以盐醋淹食之。
【气味】辛，涩，热，无毒。
【主治】妇人血气痛，洗焙研末，酒服半钱。孕妇勿服，能消胎气。忌鸡、鱼、羊血、
湿面（苏颂）。
（《纲目》）
【集解】时珍曰∶刘松石《保寿堂方》云∶白龙须生近水旁有石处，寄生搜风树节，乃
树之余精也。细如棕丝，直起无枝叶，最难得真者。一种万缠草，生于白线树根，细丝相类，
但有枝茎，稍粗为异。误用不效。愚案∶所云二树名皆隐语，无从考证。
【气味】缺平，无毒。
【主治】男子妇人风湿腰腿疼痛，左瘫右痪，口目 斜，及产后气血流散，胫骨痛，头
目昏暗，腰腿痛不可忍，并宜之。惟虚劳瘫痿不可服。研末，每服一钱，气弱者七分，无灰
酒下。密室随左右贴床卧，待汗出自干，勿多盖被，三日勿下床见风。一方∶得疾浅者，用
末三钱，瓷瓶煮酒一壶。每日先服桔梗汤少顷，饮酒二盏。早一服，晚一服（《保寿堂方》）。
【发明】时珍曰∶《保寿方》云∶成化十二年，卢玄真道士六十七岁，六月偶得瘫痪，
服白花蛇丸，牙齿尽落。三年扶病入山，得此方，服百日，复旧，寿至百岁乃卒。凡男妇风
湿腰腿痛，先服小续命汤及渗湿汤后，乃服此。凡女人产后腰腿肿痛，先服四物汤二服，次
日服此。若瘫痪年久，痰老气微者，服前药出汗，三日之后，则日服龙须末一分，好酒下。
隔一日服二分，又隔一日服三分，又隔一日服四分，又隔一日服五分。又隔一日，复从一分
起，如前法，周而复始。至月余，其病渐愈。谓之升阳降气，调髓蒸骨，追风逐邪，排血安
神。忌房事、鱼、鹅、鸡、羊、韭、蒜、虾、蟹，及寒冷动风之物。又不可过饮酒及面食，
只宜米粥、菜蔬。
【附方】新一。
诸风瘫痪，筋骨不收∶用白龙须根皮一两，闹羊花（即老虎花）七分，好烧酒三斤，封
固，
煮一炷香，埋土中一夜。能饮者三杯，不能饮者一杯，卧时服。服至三、五杯，见效。但知
痛者可治。（坦仙《皆效方》）
(Song Dynasty *Tu Jing Ben Cao*)
[Collected Explanations] Song said: It grows in Shizhou. The seedling is about one chi high, with purple backs on the leaves and no flowers. Local people harvest the roots for use.
Shizhen said: It is found everywhere in the waterside rocky areas of Huxiang, named Jinpan Teng (Golden Plate Vine). It resembles Cu Tong Cao (Vinegar Tube Herb) but has smaller leaves with slightly purple backs. The soft stems creep like Huang Si (Yellow Silk), breaking upon rubbing without visible juice. Alchemists use it to refine mercury. It is rare in other places. Cu Tong Cao: Leaves resemble those of Hibiscus mutabilis (Cotton Rose) but are asymmetrical; stems are hollow and brittle, taste sour, and produce white flowers. People in Guangdong pickle and eat them with salt and vinegar.
[Flavor and Properties] Pungent, astringent, hot, non-toxic.
[Indications] For women's blood and qi pain, wash, bake, grind into powder, and take half qian with wine. Pregnant women should not take it, as it can dissipate fetal qi. Avoid chicken, fish, sheep blood, and wet dough (Su Song).
(*Ben Cao Gang Mu*)
[Collected Explanations] Shizhen said: Liu Songshi's *Baoshou Tang Fang* states: Bailong Xu (White Dragon Whisker) grows near water beside rocks, parasitizing the nodes of Soufeng Tree, being the residual essence of the tree. It is fine like palm fibers, growing straight up without branches or leaves, making true specimens very hard to obtain. There is a Wan Chan Cao (Ten Thousand Wrapping Grass) that grows at the roots of Baixian Tree, similar in fine threads but distinguished by having branches and stems, being slightly thicker. Misuse is ineffective. My research indicates: The names of these two trees mentioned are all cryptic terms, making verification impossible.
[Flavor and Properties] Lacking "Ping" (Neutral), non-toxic.
[Indications] For wind-dampness causing waist and leg pain in men and women, left hemiplegia and right paralysis, facial paralysis (deviation of mouth and eyes), and postpartum scattering of blood and qi, tibia pain, dim vision, and unbearable waist and leg pain, this is suitable. Only cases of deficiency consumption leading to paralysis and flaccidity should not take it. Grind into powder, take 1 qian per dose, or 0.7 qian for those with weak qi, taken down with ashless wine. Lie in a sealed room, lying on either side against the bed, waiting for sweat to dry naturally. Do not cover with too many blankets, and do not get out of bed to see wind for three days. Another method: For mild disease, use 3 qian of powder, boil one pot of wine in a porcelain bottle. Each day, first drink a little Jiegeng Tang (Platycodon Decoction), then drink two cups of wine. Take once in the morning and once in the evening (*Baoshou Tang Fang*).
[Elucidation] Shizhen said: *Baoshou Fang* records: In the 12th year of Chenghua, Daoist Lu Xuanzhen, aged 67, suddenly suffered from paralysis in June. After taking Baihua She Wan (White Flower Snake Pill), all his teeth fell out. Three years later, he entered the mountains while ill, obtained this prescription, took it for 100 days, recovered completely, and lived to be 100 years old before passing away. For any man or woman with wind-dampness waist and leg pain, first take Xiao Xuming Tang (Minor Continuation of Life Decoction) and Shen Shi Tang (Dampness Percolating Decoction), then take this. For women with postpartum waist and leg swelling and pain, first take Si Wu Tang (Four Substances Decoction) twice, then take this the next day. If paralysis has lasted for years, with old phlegm and weak qi, after sweating from taking the previous medicines, start taking 1 fen of Long Xu (Dragon Whisker) powder daily with good wine after three days. Every other day increase to 2 fen, then 3 fen, then 4 fen, then 5 fen. After another interval, return to 1 fen and repeat the cycle. After more than a month, the illness gradually heals. This is called raising yang and descending qi, regulating marrow and steaming bone, pursuing wind and driving out evil, expelling blood and calming spirit. Avoid sexual intercourse, fish, goose, chicken, sheep, leeks, garlic, shrimp, crab, and cold foods that stir wind. Also avoid excessive alcohol and wheat products; only rice porridge and vegetables are suitable.
[Attached Prescriptions] One new prescription.
Various wind-induced paralysis with loose tendons and bones: Use 1 liang of root bark of Bailong Xu, 7 fen of Yaoyang Hua (Alkekengi officinarum var. franchetii / Tiger Flower), and 3 jin of good distilled liquor. Seal tightly, boil for the time it takes to burn one incense stick, bury in the earth overnight. Those who can drink take three cups; those who cannot take one cup, taken at bedtime. Taking three to five cups will show effects. Cases where pain sensation remains are treatable. (Tanxian *Jie Xiao Fang*)
