偏头痛者，由风邪客于阳经，其经偏虚者，邪气凑于一边，痛连额角，久而不已，故谓
之偏头痛也。
王荆公患偏头痛，裕陵传禁中秘方，用生莱菔汁一蚬壳，仰卧注鼻中，左痛注右，右痛
注左，或两鼻皆注亦可，数十年患，皆一注而愈。
一妇人患偏头痛，一边鼻塞不闻香臭，常流清涕，或作臭气一阵，遍治头痛药皆不效。
一医教服芎犀丸，不十数服，忽然嚏突出一铤稠脓，其疾遂愈。
芎犀丸 此方兼祛风清热之长，而得参、胶等安定气血，虽虚人亦可用之。安内
攘外，并行不悖也。
川芎 朱砂（水飞，内一两为衣） 石膏 龙脑（各四两） 人参 茯苓 炙草 细辛（各
二两） 生犀角 栀子（各一两） 阿胶（炒，一两半） 麦冬（三两，去心）
上为细末，蜜丸弹子大，每服一丸，食后细嚼，茶酒任下。
节斋云∶久病头风，略感风寒，便发寒热，头须重绵浓帕包裹者，此属本热而标寒，世
人不
识，悉用辛温散之。轻时得效，误认为寒，殊不知其本有郁热，毛窍常疏，故风易入，外寒
束其内热，闭逆而为痛。辛热之药，虽能开通闭逆，散其表之寒邪，然以热济热，病本益深
，恶寒愈甚矣。惟当泻火凉血，而佐以辛温散表之剂，以从法治之，则病可愈而根可除也。
偏头痛，是由于风邪侵袭阳经，而该经脉本身偏于虚弱，导致邪气聚集在身体的一侧，疼痛牵连到额角部位，如果长期不愈，就称为偏头痛。
王荆公（王安石）患有偏头痛，宋神宗（裕陵）从宫廷中传授秘方：取新鲜萝卜汁一蚬壳量，患者仰卧，将药液滴入鼻腔，左侧头痛则滴右侧鼻孔，右侧头痛则滴左侧鼻孔，或者双侧鼻孔都滴也可以。几十年的老毛病，往往一次滴注就能痊愈。
有一位妇人患偏头痛，一侧鼻塞，闻不到气味，经常流出清涕，有时突然散发出一阵臭气，遍用治疗头痛的药物都没有效果。
一位医生教她服用芎犀丸，不到十几服之后，忽然打喷嚏喷出一铤（古代重量单位或形状描述，此处指条状物）浓稠的脓液，她的病随即痊愈。
芎犀丸：这个方子兼具祛风和清热的特长，同时得到人参、阿胶等药物安定气血的作用，即使是体质虚弱的人也可以使用。内安正气，外祛邪气，两者并行不悖。
川芎 朱砂（水飞法处理，作为内层衣料，用量一两） 石膏 龙脑（各四两） 人参 茯苓 炙甘草 细辛（各二两） 生犀角 栀子（各一两） 阿胶（炒制，一两半） 麦冬（三两，去心）
以上药材研成细末，用蜂蜜制成如弹子大小的蜜丸。每次服用一丸，饭后细细咀嚼，茶或酒送服均可。
节斋说：久病的头风症，稍微感受风寒，就会发作寒热症状，头部必须用厚棉和多层帕子包裹才能缓解的，这属于本证为热而标证为寒。世人不懂这个道理，全都使用辛温发散的方法治疗。病情轻时似乎有效，误认为是寒证，却不知道其根本有郁积的热邪，毛孔常处于疏松状态，所以风邪容易侵入，外部的寒邪束缚住内部的热邪，导致气机闭逆而产生疼痛。辛热性质的药物，虽然能够开通闭阻的气机，疏散体表的寒邪，但是以热助热，会使疾病的根本更加深重，恶寒的症状也会更加严重。只应当泻火凉血，并佐以辛温解表的药剂，按照正确的法则治疗，那么疾病可以痊愈，病根也可以去除。
Pian Tou Tong (Hemicrania) arises when Wind pathogenic factors invade the Yang meridians. When a specific meridian is relatively deficient, the pathogenic factors gather on one side, causing pain that radiates to the frontal angle of the head. If this condition persists for a long time without resolution, it is termed Pian Tou Tong (Hemicrania).
Wang Jinggong (Wang Anshi) suffered from Pian Tou Tong (Hemicrania). Emperor Shenzong of Song transmitted a secret prescription from the imperial palace: take fresh Radish Juice (Lai Fu Zhi) in the quantity of one shell of a clam. The patient lies supine, and the juice is instilled into the nasal cavity. If the pain is on the left, instill into the right nostril; if on the right, instill into the left nostril; or both nostrils may be instilled simultaneously. A chronic condition lasting decades could often be cured with a single application.
A woman suffered from Pian Tou Tong (Hemicrania), with nasal congestion on one side, loss of smell, frequent discharge of clear mucus, and occasional bursts of foul odor. Treatments for headache proved ineffective.
A physician instructed her to take Xiong Xi Wan (Platycodon and Rhinoceros Horn Pill). After less than ten doses, she suddenly sneezed out a strip of thick pus, and her illness was subsequently cured.
Xiong Xi Wan (Platycodon and Rhinoceros Horn Pill): This formula excels in dispelling Wind and clearing Heat. It also incorporates Ren Shen (Ginseng Root) and E Jiao (Donkey-hide Gelatin) to stabilize Qi and Blood, making it suitable even for patients with deficiency. It secures the interior while expelling pathogens externally, allowing both actions to proceed without contradiction.
Chuan Xiong (Ligusticum Chuanxiong Rhizome); Zhu Sha (Cinnabar, processed by water flotation, used as an inner coating, 1 liang); Shi Gao (Gypsum Fibrosum); Long Nao (Borneol) (each 4 liang); Ren Shen (Ginseng Root); Fu Ling (Poria); Zhi Gan Cao (Prepared Licorice Root); Xi Xin (Asari Root) (each 2 liang); Sheng Xi Jiao (Rhinoceros Horn, raw); Zhi Zi (Gardenia Fruit) (each 1 liang); E Jiao (Donkey-hide Gelatin, stir-fried, 1.5 liang); Mai Dong (Ophiopogon Tuber) (3 liang, heart removed).
Grind all ingredients into a fine powder. Mix with honey to form pills the size of quince seeds. Take one pill per dose, chew thoroughly after meals, and swallow with tea or wine as preferred.
Jie Zhai stated: For chronic Tou Feng (Head Wind), where slight exposure to Wind-Cold triggers chills and fever, and the head requires wrapping in thick cotton and multiple scarves for relief, this pattern belongs to "Root Heat and Branch Cold." People of the world do not recognize this and uniformly use Acrid-Warm dispersing methods. When the condition is mild, it seems effective, leading to the mistaken belief that it is a Cold pattern. However, the root involves stagnant Heat, and the pores are often loose, allowing Wind to enter easily. External Cold binds the internal Heat, causing obstruction and rebellious Qi flow, resulting in pain. Acrid-Warm herbs can open obstructions and disperse external Cold, but using Warmth to assist Heat deepens the root pathology and exacerbates aversion to cold. One should instead purge Fire and cool Blood, assisted by Acrid-Warm exterior-releasing agents, treating according to the correct principle. Then the disease can be cured, and its root eradicated.
