（本经中品）
惟其卒暴，故不觉其所从来。
【气味】苦咸平，无毒。
【主治】主暴中风，身热，支满，忽忽不知人，狂惑邪气，寒热酸疼，温疟洗洗，发作
有时
【核】曰∶出陕西，及舒、滁、润、辽诸州，近以山东沂濮、莒莱诸州者称胜。茎叶俱
青，颇类柳叶。六、七月开红色花，遂结实。根似牛膝而细，长尺许。色黄微白，芳香袭人
者，白薇也；色白微黄，折之易断者，白前也。修治，用糯米泔浸一宿，去髭，槐砧上锉细，
蒸之，从申至巳，晒干用。恶黄 、大黄、大戟、干姜、大枣、干漆、山茱萸。
【 】曰；白薇，别名白幕。白者，金色，坚刚之体也。微者，隐也，隐身而行。幕者，
军行之幕，以隐身也。此指能治因所治证，以诠名耳。气平，味苦咸，平则不上不下，敦土
德化，御所不胜也。炎上作苦，苦性走下，苦能入骨，润下作咸，咸性走血，咸能 坚，从
巅及踵，沦肤彻髓，靡不周到者也。谓所胜因，善行数变，亦靡不周遍故也。故主因于暴风，
隐身而为身热肢满，忽忽不知人，狂惑邪气，寒热酸疼，此风气留其处，故隐身而尝在也。
或隐身而行，而为温疟洒洒，发作有时，此风并卫居，随卫气之昼行于阳，夜行于阴，沉以
内薄，故发有期，而时作时休也。此皆暴风数变之证，金以制之，制所胜也。别录主淋露遗
尿，即风隐膀胱也。若水气精损，即风隐于肾，致令肾虚精涸，肾虚水泛也。若忽如死人，
即风隐于血，致令血厥也。若温病多眠，即风隐于脉道，致令卫气不得昼行于阳也。若痉则
风隐于筋，惊则风行致令气上也。咸以暴风为因，寒则非所宜矣。
(Shennong Bencao Jing, Middle Category)
Because the onset is sudden and violent, people are unaware of its origin.
[Flavor and Nature] Bitter, salty, neutral in nature, non-toxic.
[Indications] Primarily treats sudden stroke (Bao Zhong Feng), fever, distension and fullness in the chest and hypochondrium, mental confusion or unconsciousness, madness, delirium, and pathogenic qi invasion; also treats alternating chills and fever, body aches; for warm malaria (Wen Nue) with shivering chills, occurring at fixed times.
[Verification] It is stated: Baiwei grows in Shaanxi, as well as in Shuzhou, Chuzhou, Runzhou, and Liao Zhou. Recently, those produced in Yizhou, Puzhou, Juzhou, and Laizhou in Shandong are considered superior. The stems and leaves are all green, resembling willow leaves. In June and July, it bears red flowers and subsequently produces fruit. The root resembles Niuxi (Achyranthis Bidentatae Radix) but is finer, about one chi long. Those that are yellowish-white with a strong aromatic fragrance are Baiwei; those that are whitish-yellow and break easily are Baiqian (Cynanchi Stauntonii Radix). Processing method: Soak overnight in rice washing water, remove the root hairs, chop finely on a locust wood cutting board, steam from Shen hour to Si hour, then dry in the sun for use. It is incompatible with Huang Qin (Scutellariae Radix), Dahuang (Rhei Radix et Rhizoma), Daji (Euphorbiae Pekinensis Radix), Ganjiang (Zingiberis Rhizoma), Dazao (Jujubae Fructus), Ganqi (Lacca Resina), and Shanzhuyu (Corni Fructus).
[Interpretation] It is said: Baiwei, alias Baimu. "Bai" (White) represents the metal element's color, symbolizing a firm and rigid constitution. "Wei" (Micro/Subtle) means hidden, referring to moving while concealed. "Mu" (Curtain/Tent) refers to the military tent used for concealment during troop movements. This explains the name based on the conditions it can treat. Its nature is neutral, with bitter and salty flavors. Neutrality implies neither ascending nor descending, embodying the transformative virtue of Earth, thereby resisting what it cannot overcome (controlling the counter-restrictive cycle). Fire flares upward producing bitterness; bitter substances tend to descend, and bitterness can enter the bones. Water moistens downward producing saltiness; salty substances tend to enter the blood, and saltiness can strengthen the sinews/bones. The medicinal effect reaches from the crown of the head to the heels, penetrating the skin and marrow, reaching everywhere. This refers to the cause of what it overcomes (Metal controls Wood); wind moves swiftly and changes frequently, thus reaching everywhere. Therefore, it primarily treats symptoms caused by violent winds, such as fever and limb fullness where the pathogen hides, mental confusion/unconsciousness, madness, delirious pathogenic qi, alternating chills/fever, and body aches. This is because wind qi remains in place, so it "hides" and is constantly present. Or, due to moving while hidden, it causes warm malaria with shivering chills occurring at fixed times. This is because wind resides with Wei Qi (Defensive Qi), following Wei Qi's daytime movement in the Yang levels and nighttime movement in the Yin levels. The pathogen deeply invades internally, so attacks have a regular schedule, alternating between发作 (onset) and rest. These are all manifestations of violent, changing winds. Metal-type properties control them, i.e., controlling what they overcome (Wind/Wood). The *Bielu* states it treats strangury, seminal emission, and urinary incontinence, which is wind hiding in the Bladder. If there is fluid/qi damage and essence depletion, it is wind hiding in the Kidney, causing Kidney deficiency, essence exhaustion, and overflowing Kidney water. If one suddenly appears like a corpse, it is wind hiding in the Blood, causing Blood Jue (syncope). If warm disease involves excessive sleepiness, it is wind hiding in the meridians, preventing Wei Qi from moving in the Yang levels during the day. If there is spasm, wind hides in the sinews; if there is fright, wind movement causes Qi to rise. Since the cause is violent wind, cold-natured treatments are not suitable.
