长眉法（岐天师） 眉落用桑叶七片，每日洗之，一月重生如旧，须落亦然。
《鬼遗方》云∶左右眉棱两处发，名为发眉，不拘在头在尾，宜防未穴已前毒瓦斯
攻击，在眉头即攻入眼损睛，在眉尾即攻
入太阳，并宜留意慎重。此疽从眉至头生疮黑色，渐渐肿漫，满面疮头，坚硬如石，
刺之无脓，惟出黄水，痛不可恶，闷乱呕逆是也。由脏腑积热，风毒上攻而然。（《准绳》）

申斗垣曰∶眉疽生于阳白二穴之分，乃足少阳胆经多气少血。治之诸证渐减者生，
甚者死，女人七日、男子二十四日死。（启玄）
又曰∶眉风毒，乃肺经受证，但觉寒热往来，筋骨酸痛，或作呕吐，即眉风毒也。
窦汉卿曰∶从眉至头发疽色黑，其腰渐渐肿，气浮满面者死。
《心法》曰∶凤眉毒，一名眉发，生于眉棱，无论左右，皆膀胱、小肠、肝、胆
四经积热所致。形长如爪，疼痛引脑，二目合肿，坚硬色赤，按之有根，六日内刺
之，得脓则吉，无脓则险，甚则十四朝不溃，烦闷呕逆，不食者凶。
李东垣曰∶眉疽生于两眉之间，灿烂
如人眼目，甚可畏也。小儿患此必死，大人患此十痊五六，乃手足少阳经所主，宜
用海马崩毒法救之。不然，脓血浸眼，两目先坏矣。
澄曰∶发眉其证极险，类乎疔疮。第一提住疮根，不使根脚散漫，内须托毒成
脓，勿投寒凉破气伤脾之药，庶可保全性命。
长眉法（岐天师）：眉毛脱落者，用桑叶七片，每日清洗患处，一个月后眉毛会重新长出，如同从前一样；胡须脱落的情况也是如此。
《鬼遗方》记载：左右眉棱骨两处发病，称为“发眉”，无论发生在眉头还是眉尾，都应当预防毒气攻击未病之处。如果病灶在眉头，毒气就会攻入眼睛损伤视力；如果在眉尾，毒气就会攻入太阳穴。对此都应留意并谨慎对待。这种疽疮从眉毛处长到头部，疮色发黑，逐渐肿胀蔓延，满脸都是疮头，质地坚硬如石头，刺破后没有脓液，只流出黄色水液，疼痛剧烈且令人厌恶，伴有胸闷烦乱、呕吐逆气等症状。这是由于脏腑积热，风毒上攻所致。（出自《医学准绳六要》）
申斗垣说：眉疽生在阳白穴所在的区域，属于足少阳胆经，该经脉多气少血。治疗时如果各种症状逐渐减轻，患者就能存活；如果病情严重，则会导致死亡，女性七日死，男性二十四日死。（出自《启玄子本草》）
申斗垣又说：眉风毒，是肺经受邪所致，只觉得寒热往来，筋骨酸痛，或者出现呕吐，这就是眉风毒。
窦汉卿说：从眉毛处长到头发处的疽疮颜色发黑，腰部逐渐肿胀，气息浮泛于满面者，预后不良，主死。
《医宗心法》说：凤眉毒，又名眉发，生于眉棱骨处，无论左右，都是由膀胱、小肠、肝、胆四条经络积热引起的。形状像爪子一样长，疼痛牵引至脑部，双眼同时肿胀，质地坚硬且颜色发红，按压时有根基。发病六天内刺破排脓，若是能出脓则吉利，无脓则危险，严重时十四天也不溃破，若出现烦闷呕吐、不能进食，则为凶兆。
李东垣说：眉疽生在两眉之间，灿烂明亮如同人的眼睛，非常可怕。小儿患此病必死无疑，成人患此病十人能痊愈五六人，这是由手足少阳经所主，适宜使用海马崩毒法来救治。否则，脓血浸染眼睛，双眼先会毁坏。
顾世澄说：发眉疽的证候极其险恶，类似于疔疮。首先要控制住疮根，不让根脚扩散蔓延，内部必须托毒外出形成脓液，不要投用寒凉、破气、伤脾的药物，这样才可以保全性命。
Changmei Fa (Method for Growing Eyebrows, by Tianzi Qi): For those with fallen eyebrows, use seven mulberry leaves to wash the area daily. Within one month, the eyebrows will regrow as before; the same applies to beard loss.
The *Guiyi Fang* states: When lesions appear on both sides of the brow ridge, it is named "Famei" (Eyebrow Carbuncle). Regardless of whether it occurs at the inner or outer end of the eyebrow, one must guard against the attack of toxic vapors to unaffected areas. If located at the inner brow, the toxicity attacks the eyes and damages vision; if at the outer brow, it attacks the Taiyang region. Careful attention and caution are required in all cases. This type of ju (carbuncle/abscess) starts from the eyebrow and spreads to the head, presenting with black sores that gradually swell and spread, covering the face with numerous sore heads. The texture is hard as stone. Puncturing yields no pus, only yellow fluid. It is characterized by unbearable pain, aversion to the lesion, mental restlessness, and vomiting with counterflow qi. This results from accumulated heat in the zang-fu organs and upward attack of wind-toxicity. (From *Zhunsheng*)
Shen Douyuan stated: Meiju (Eyebrow Abscess) arises in the area of the Yangbai acupoint, which belongs to the Foot-Shaoyang Gallbladder Meridian, a meridian characterized by abundant qi and scarce blood. If symptoms gradually subside with treatment, the patient survives; if severe, death ensues—within seven days for women and twenty-four days for men. (From *Qixuan*)
He also stated: Meifengdu (Eyebrow Wind-Toxicity) is a syndrome affecting the Lung Meridian, manifesting as alternating chills and fever, soreness and pain in bones and sinews, or vomiting. This constitutes Meifengdu.
Dou Hanqing stated: When a du (malignant abscess) spreads from the eyebrow to the hairline, presenting with black coloration, gradual swelling of the neck/waist area, and floating qi across the full face, the prognosis is fatal.
The *Xinfa* states: Fengmeidui (Phoenix Eyebrow Toxicity), also known as Meifa, arises on the brow ridge. Regardless of side, it is caused by accumulated heat in the Bladder, Small Intestine, Liver, and Gallbladder meridians. It appears elongated like a claw, causes pain radiating to the brain, and results in simultaneous swelling of both eyes. It is hard, red, and has a deep root upon palpation. If punctured within six days and pus is obtained, the outcome is auspicious; if no pus forms, the condition is perilous. If it fails to ulcerate even after fourteen days, accompanied by irritability, vomiting, and anorexia, the prognosis is ominous.
Li Dongyuan stated: Meiju arises between the two eyebrows, appearing bright and radiant like human eyes, which is extremely fearsome. Infants suffering from this condition will certainly die; adults have a survival rate of five or six out of ten. This condition is governed by the Hand and Foot Shaoyang meridians. One should employ the Seahorse Detoxification Method to save the patient. Otherwise, pus and blood may infiltrate the eyes, causing blindness first.
I, Cheng, state: The manifestation of Famei is extremely dangerous, resembling Dingchuang (hard carbuncle). The primary step is to secure the root of the sore, preventing the base from spreading diffusely. Internally, one must support the expulsion of toxicity to form pus. Avoid administering cold-natured, qi-breaking, or spleen-damaging herbs. Only then can life be preserved.
