无毒。
白龙须（出自《本草纲目》）：主治男子和妇女的风湿性腰腿疼痛、左侧或右侧肢体瘫痪、口眼歪斜，以及产后气血散乱导致的胫骨疼痛。头部昏花、眼睛昏暗、腰腿疼痛难以忍受者，均适宜服用。唯独虚劳引起的瘫痿症状不可服用。将药研成细末，每次服用一钱；体质气弱之人服用七分，用无灰酒送服。服药后在密室中，根据患侧左右，贴着床卧躺，等待汗液自然流出并自行干燥，不要盖过多的被子。三天内不要下床见风。另一方法：对于患病时间较短浅的人，使用药末三钱，放入瓷瓶中煮酒一壶，每天先服用桔梗汤，过一会儿再饮酒一盏，早晨一次，晚上一次（出自《保寿堂方》）。
【产地】（李时珍说）（刘松石《保寿堂方》记载）：白龙须生长在靠近水边且有石头处，寄生在搜风树的节上，这是树木的余精。
【形态】：茎叶细长如同棕丝，直立生长，没有枝叶，最难得的是真品。有一种万缠草，生长在白线树根旁，细丝相似，但稍有枝茎且较粗，以此作为区别。误用也无妨。我按语认为，上述所说的两种树名都是隐语，无法考证。
【味道】：缺失。
【性质】：平性。
【主治】（李时珍说）（《保寿方》记载）：成化十二年，道士卢玄真六十七岁时，六月偶然患上瘫痪，服用白花蛇丸导致牙齿全部脱落。三年间带病入山，得到此方，服用一百天后恢复健康，寿命至百岁才去世。凡是男女风湿腰腿痛，先服用小续命汤及渗湿汤，然后再服用此药。凡是妇女产后腰腿肿痛，先服用四物汤两剂，次日再服用此药。如果是瘫痪多年、痰浊老固、气息微弱者，服用前述药物出汗三天之后，则每日服用龙须末一分，用好酒送服；隔一日服用二分；又隔一日服用三分；又隔一日服用四分；又隔一日服用五分；再隔一日又从一分开始，如前法循环往复，直到一个月左右，病情逐渐痊愈。这叫做升阳降气、调髓蒸骨、追风逐邪、排血安神。忌食房事，以及鱼、鹅、鸡、羊、韭菜、大蒜、虾、蟹等食物，还有寒冷动风之物。也不可过量饮酒及食用面食，只宜吃米粥和蔬菜。
【合治】：治疗各种风症瘫痪、筋骨松弛不收，用白龙须根皮一两，闹羊花（即老虎花）七分，好烧酒三斤，密封牢固，煮一炷香的时间，埋入土中一夜。能喝酒的人饮三杯，不能喝酒的人饮一杯，睡前服用。服用至三五杯见效。如果还能感觉到疼痛，说明可以治愈。

Bailongxu (White Dragon Whisker) [Source: *Bencao Gangmu*]: Indicated for wind-dampness pain in the waist and legs of men and women, hemiplegia (left or right), deviation of the mouth and eyes, and tibia pain caused by the dispersion of qi and blood after childbirth. It is suitable for dizziness, dim vision, and unbearable pain in the waist and legs. However, it should not be taken for paralysis and atrophy caused by deficiency-labor (Xu Lao). Grind into powder; take one qian per dose. For those with weak qi, take seven fen. Take with unadulterated wine. After taking the medicine, lie on the bed in a sealed room, positioning oneself according to the affected side (left or right), waiting for sweat to appear naturally and dry itself. Do not cover with too many blankets. Do not get out of bed to expose oneself to wind for three days. Another prescription: For those with shallow/recent onset of disease, use three qian of powder, boil one pot of wine in a porcelain bottle. First take Jiegeng Tang (Platycodon Decoction), then after a while drink one zhan of wine. Take once in the morning and once in the evening (Source: *Baoshoutang Fang*).
[Origin] (Li Shizhen said): (According to Liu Songshi's *Baoshoutang Fang*): Bailongxu grows near water sources where stones are present, parasitizing on the nodes of the "Sofeng Tree" (Search-Wind Tree); it is the residual essence of the tree.
[Morphology]: The stems are fine like palm fibers, growing upright without branches or leaves. The authentic specimen is rare. There is a plant called Wanchan Cao (Ten-Thousand Coiling Grass) that grows near the roots of the Baixian Tree (White Line Tree); its fine filaments are similar, but it has slightly thicker stems and branches, which serves as the distinction. Accidental misuse is harmless. My commentary notes that the names of these two trees mentioned above are cryptic terms and cannot be verified.
[Taste]: Missing.
[Nature]: Neutral.
[Indications] (Li Shizhen said): (Recorded in *Baoshou Fang*): In the 12th year of Chenghua (1476 AD), Daoist Lu Xuzhen, aged 67, accidentally suffered from paralysis in June. He took Baihua She Wan (White Flower Snake Pill), which caused all his teeth to fall out. For three years, he lived with illness in the mountains until he obtained this prescription. After taking it for 100 days, he recovered his health and lived to the age of 100 before passing away. For men and women suffering from wind-dampness pain in the waist and legs, first take Xiaoxuming Tang (Minor Continuation of Life Decoction) and Shen Shi Tang (Damp-Percolating Decoction), and then take this medicine. For women with swelling and pain in the waist and legs after childbirth, first take Siwu Tang (Four Substances Decoction) for two doses, and take this medicine on the following day. For cases of long-standing paralysis with old phlegm and weak qi, after sweating for three days from taking the aforementioned medicines, take one fen of Longxu powder daily, administered with good wine. Every other day, increase the dose: two fen, then three fen, then four fen, then five fen. Then, every other day, return to one fen and repeat the cycle. Continue until about one month passes, during which the illness gradually improves. This method is described as raising yang and descending qi, regulating marrow and steaming bone, pursuing wind and driving out evil, expelling blood and calming the spirit. Avoid sexual intercourse, and foods such as fish, goose, chicken, mutton, leeks, garlic, shrimp, and crab, as well as cold and wind-aggravating substances. Also avoid excessive alcohol consumption and wheat/flour products; only rice porridge and vegetables are suitable.
[Combined Treatment]: For various wind-induced paralysis and flaccidity of tendons and bones, use one liang of the root bark of Bailongxu, seven fen of Yaoyang Hua (also known as Laohu Hua/Tiger Flower), and three jin of good distilled liquor. Seal tightly, boil for the duration of one incense stick, and bury in the earth overnight. Those who can drink may consume three cups; those who cannot drink may consume one cup. Take before sleep. Effectiveness is seen when consuming three to five cups. If pain sensation remains, the condition is treatable.
