清淡的饭菜和清茶，有助于保全健康直至百年长寿；如果多愁善感且容易生病，那是出于无奈。努力亲近酒杯（指饮酒），因为心中勾心斗角、相思债未了。导致三阳经亢盛之火向上炎蒸，容貌神态发生改变。眼睛和耳朵互相障碍不通，头部及颈部无论大小部位都感到不适。疼痛如同被炮烙一般，片刻难以忍受。浮生两字真是虚幻的梦，满腔热血变成了寒冷的急流。问什么时候才能得到返魂香，来熏染衣带。
这种病症表现为发热恶寒，头面部随着肿胀而疼痛，眼睛发红，眼屎多且流泪，不敢面对光亮坐卧。这是因为风痰湿热，结合太阴燥气飞越所致。长夏和高秋季节，以及身体虚弱肥胖的人患此病较多。如果失治，恐怕热邪闭塞导致神膏浑浊污损，等到肿胀消退后病变就会发生。应当使用九味羌活汤、清空散。如果无效，可用麻桂饮或大温中饮。如果是初起时憎恶寒冷而后发热，一两天后热势旺盛而无寒冷，脉象浮大而数或弦燥，头痛身痛，耳聋口渴，双眼红得像火一样。这是时疫病的发作，不是眼疾，也不是伤寒。应服用达原饮、普济消毒饮、清平丸。如果病情拖延不愈，头面部继续肿胀，像僧人的罄或葫芦一样，这是毒邪盘踞在胃中，隔绝了元府，使表气不能通达内部，里气不能到达外部，游溢于上部，发为奇肿，俗名大头瘟。用大柴胡汤急下以承接其气，继用十神汤、小续命汤，通过出狂汗或发斑而解。然而这种病症最容易传染，福薄者即会毙命，医家自当慎重，不要随意图谋医治他人。
雷头风突然发作，壮热且憎恶寒冷，头脑感觉如同被烙铁烫过，眼球酷似被钻子钻痛，气息粗重痰液易上涌，火秘便通困难，怠慢疏忽过了时刻，即使是天医也难以往返救治。
这种病症不论偏正头风，只要憎寒壮热，症状像伤寒，头目疙瘩，肿痛极其严重，不能忍耐的就是。或者挟带痰邪而来，两耳像雷鸣风动，轰轰作响，所以叫雷头风。风起则目随病，继而身体像被杖打一样，二便秘结，叫做大雷头风。头风发作时，大便先润后燥，小便先清长后赤涩，身热慢慢退去且不痛，叫做小雷头风。大的危害迅速，小的稍缓，两三天后眼睛就会损坏，神医也无法治疗。眼睛损坏且疼痛不止，生命就危险了。《难经》说头痛有厥痛、真痛。厥者，逆也；真者，无其他杂症。面肿头重，按压不得，项先痛，腰脊相应。前后脉涌有热。这是风寒潜伏在手三阳经，停留不去，壅逆作病，头为阳首，发为厥痛。如果再传入脑户，则手足必寒，爪甲必青，死不治。初起不问大小雷风，三阳厥逆，五邪争并，不辨为火、为风、为痰，脉息对症与否，速与大承气汤或三黄祛热煎，火得息则痰自散，而风亦渐止。如表症未罢，菊花通圣散先投看效。倘脉浮芤或沉濡而迟，服前方反剧，亟换调中益气、全真一气、大补元等汤。能开导针砭，根据图施治，尤为快便。

Light meals and clear tea help preserve health for a hundred years; being prone to worry and illness is often beyond one's control. Strive to engage with wine, as the entangled thoughts and debts of longing remain unresolved. This leads to the hyperactivity and flaming upward of fire in the Three Yang meridians, altering one's appearance and demeanor. The eyes and ears become mutually obstructed, and the head and neck suffer discomfort regardless of size. The pain is like being branded by hot iron, unbearable even for an instant. Life is but an illusory dream, and passionate blood turns into cold rapids. One asks when the incense of returning soul will arrive to scent the clothes and sash.
This condition presents with fever and aversion to cold, swelling and pain in the head and face, red eyes, excessive discharge and tearing, and an inability to sit or lie down facing light. It is caused by wind-phlegm-damp-heat combined with the flying away of Taiyin dryness. It occurs frequently during late summer and high autumn, especially in those who are deficient and obese. If neglected, heat may close off pathogens, causing the divine fluid (shen gao) to become turbid; changes will manifest after the swelling subsides. Jiwei Qianghuo Decoction (Nine-Ingredient Notopterygia Decoction) or Qingkong San should be used. If ineffective, Magui Yin or Da Wenzhong Yin may be employed. If chills precede fever initially, followed by intense heat without chills after one or two days, with a floating, large, rapid, wiry, or dry pulse, headache, body ache, deafness, thirst, and eyes burning like fire, this is an epidemic disease, not an eye disorder or Shaoyang syndrome. Dajian Yin, Puji Xiaodu Yin, and Qingping Wan should be administered. If the condition persists, continued swelling of the head and face resembling a monk's singing bowl or gourd indicates toxic pathogens lodging in the Stomach, blocking the Yuan Fu (primary gates), preventing exterior Qi from entering and interior Qi from exiting, overflowing upwards to cause strange swelling, commonly known as Big Head Plague (Datou Wen). Da Chaihu Tang should be used urgently to purge and support Qi, followed by Shishen Tang and Xiao Xuming Tang. Resolution comes through wild sweating or purpura. However, this condition is highly contagious; those with weak constitution may die. Physicians must exercise caution and not treat lightly.
Sudden onset of Leifeng (Thunderhead Wind) involves high fever and aversion to cold, head feeling as if branded, eyeballs feeling as if drilled, coarse breathing with easy phlegm ascent, constipation due to fire, and difficulty urinating. Negligence over time makes even heavenly physicians unable to save the patient.
Regardless of lateral or central headache, if there is aversion to cold and high fever resembling Shaoyang syndrome, with nodules in the head and eyes, extreme swelling and pain that is unbearable, it is likely accompanied by phlegm. If the ears sound like thunder and wind, roaring loudly, it is called Leifeng. When wind rises, the eyes follow the pathology, leading to a body feeling as if beaten, with constipation of both stool and urine, termed Dalie Touteng (Big Thunderhead Wind). When headache occurs, stool becomes moist then dry, urine clear and profuse then red and difficult, with gradual fever reduction and no pain, it is called Xiaolie Touteng (Small Thunderhead Wind). The severe form acts quickly, the mild form slowly; within two to three days, eye damage occurs, which even divine physicians cannot cure. Eye damage with unceasing pain indicates critical danger. The Nan Jing states that headaches can be Jue (rebellious) or Zhen (true). Jue means rebellion; Zhen means no other mixed pathologies. Facial swelling and heavy head, unpressable, neck pain first, corresponding lower back and spine, surging pulses with heat. This is wind-cold lurking in the Hand Three Yang meridians, lingering and causing obstruction and rebellion. As the head is the summit of Yang, it manifests as Jue pain. If it transmits to Naohu, hands and feet will become cold, nails cyanotic, and death is inevitable. Initially, regardless of severity, if Three Yang rebellious reversal occurs with five evils competing, without distinguishing fire, wind, or phlegm, and if pulse matches symptoms, administer Dachengqi Tang or Sanhuang Reqi Jian immediately. Once fire subsides, phlegm disperses, and wind stops. If exterior symptoms persist, Juhua Tongsheng San may be tried first. If the pulse is floating and hollow or deep, soft, and slow, and previous formulas worsen the condition, urgently switch to Tiaozhong Yiqi, Quanzhen Yiqi, or Dabu Yuanyuan decoctions. Acupuncture and cupping guided by diagrams are particularly effective.
Leifeng is the most dangerous condition in ophthalmology, often leading to blindness. Therefore, predecessors only discussed its danger, never investigating meridian treatment methods, leaving me with private regret to this day.
