《素问》论疟而无治法，《千金》虽传治法，试之无效。凡人暑月过啖冷物，轻则伤胃，重则伤脾。若初
起先寒后热，一日一发，乃胃疟也，易治。或吐，或下，不过十日而愈。扁鹊正法，服四神丹，甚者灸中脘穴
三十壮愈。（此证感浅病轻，人多忽略。雍正三年，秋冬之交，人皆病此，重剂温补，或可幸免，投药少瘥，
立见冰脱。用清解小柴胡者，皆不能起，宁绍之人，死者比比，以其溺用寒凉，虽一误再误，而终不悟也。）
此证皆由元气虚弱，或下元虚惫，忧恐太过，损伤心气，致鬼邪乘虚而入，令人昏迷，与鬼交通。当服睡
圣散，灸巨阙穴二百壮，鬼气自灭，服姜附汤而愈。（邪祟乌能着人，人自着之耳。果立身正直，心地光明，
不负君亲，无惭屋漏，鬼神钦敬不遑，何邪祟之敢乘哉，惟其阴幽偏颇，卑 昏柔之辈，多能感此，有似邪祟
之附着，究非邪祟也。盖由人之藏气受伤而神魂失守。故肝脏伤则意不宁，而白衣人来搏击；心脏伤则神不安，
而黑衣人来毁伤；脾脏伤则意有不存，而青衣人来殴辱；肺脏伤则魄不守，而红衣人来凌轹；肾脏伤则志多犹
疑，而黄衣人来斥辱。此皆神气受伤，以致妄有闻见，不觉其见乎四体，发乎语言，而若有邪祟所附也。正法
惟有安其神魂，定其志魄，审其何脏之虚而补之，何脏之乘而制之可也。）
治验
一妇人因心气不足，夜夜有少年人附着其体，诊六脉皆无病，余令灸上脘穴五十壮。至夜鬼来，离床五尺不能近，
服姜附汤、镇心丹五日而愈。
一贵人妻为鬼所着，百法不效。有一法师书天医符奏玉帝亦不效。余令服睡圣散三钱，灸巨阙穴五十壮，
又灸石门穴三百壮，至二百壮，病患开眼如故，服姜附汤、镇心丹五日而愈。
一妇人病虚劳，直气将脱，为鬼所着，余用大艾火灸关元，彼难忍痛，乃令服睡圣散三钱，复灸至一百五
十壮而醒。又服又灸，至三百壮，鬼邪去，劳病亦瘥。
《素问》中论述了疟疾，但没有记载治疗方法；《千金方》虽然流传着治疗疟疾的方法，但尝试使用后无效。大凡人在暑热月份过量食用生冷食物，轻则损伤胃气，重则损伤脾气。如果在发病初期先出现恶寒随后发热，每天发作一次，这就是胃疟，比较容易治疗。或者采用催吐法，或者采用泻下法，不超过十天就能痊愈。扁鹊的正统治法是服用四神丹，病情严重的艾灸中脘穴三十壮即可痊愈。（这种病症感受邪气浅、病情轻，人们往往忽略它。雍正三年，秋冬交替之际，大家都得了这种病，使用重剂量的温补药物，或许可以侥幸避免死亡；如果用药轻微导致症状稍减，立刻就会发生大便失禁（冰脱）。使用清解法配合小柴胡汤的人，都不能使患者起死回生，宁波绍兴一带的人，死者比比皆是，因为他们滥用寒凉药物，即使一误再误，却始终不醒悟。）
这种病症都是因为元气虚弱，或者下焦元阳虚惫，忧虑恐惧过度，损伤了心气，导致鬼邪乘虚而入，使人昏迷，与鬼魂交感。应当服用睡圣散，艾灸巨阙穴二百壮，鬼气自然消灭，再服用姜附汤即可痊愈。（邪祟怎么能附着在人身上呢？是人自己招致的罢了。如果立身正直，心地光明，不辜负君主和父母，在独处时也没有惭愧之心，鬼神都敬重还来不及，哪里敢有邪祟来乘虚而入呢？只有那些阴幽偏颇、卑劣昏庸柔弱之辈，多能感召此类现象，看似有邪祟附着，究其根本并非邪祟。这是因为人的脏腑之气受伤而导致神魂失守。所以肝脏受伤则意念不宁，会有穿白衣的人来搏击；心脏受伤则神志不安，会有穿黑衣的人来毁伤；脾脏受伤则意念不存，会有穿青衣的人来殴辱；肺脏受伤则魄不守舍，会有穿红衣的人来欺凌；肾脏受伤则意志多犹豫，会有穿黄衣的人来斥责侮辱。这些都是神气受伤，以致产生虚幻的见闻，不知不觉地表现在四肢动作和言语中，看起来好像有邪祟附着一样。正统的治疗方法唯有安定神魂，定住志魄，审察是哪个脏腑虚弱而补益它，哪个脏腑受邪而制约它就可以了。）
治疗验案：
有一位妇人因为心气不足，每晚都有少年人附着在她身体上，诊察六脉都没有病变，我让她艾灸上脘穴五十壮。到了晚上鬼怪来了，离床五尺就不能靠近，服用姜附汤、镇心丹五天就好了。
一位权贵夫人的妻子被鬼怪附着，各种方法都不见效。有一位法师书写天医符奏报玉帝也不见效。我让她服用睡圣散三钱，艾灸巨阙穴五十壮，又艾灸石门穴三百壮，灸到二百壮时，病患睁开眼睛如常，服用姜附汤、镇心丹五天就好了。
一位妇人患虚劳病，正气即将脱失，被鬼怪附着，我用大艾火灸关元穴，她难以忍受疼痛，于是让她服用睡圣散三钱，再次艾灸直到一百五十壮才苏醒。又服药又艾灸，直到三百壮，鬼邪去除，虚劳病也好了。
The *Suwen* (Basic Questions) discusses malaria but does not record treatment methods; although the *Qianjin Fang* (Essential Prescriptions Worth a Thousand Gold) transmits treatment methods for malaria, trials of them have proven ineffective. Generally, when people consume excessive amounts of cold substances during the hot summer months, it lightly injures the Stomach Qi or severely injures the Spleen Qi. If at the onset there is first chills followed by fever, occurring once a day, this is Wei Malaria (Stomach Malaria), which is easy to treat. Either employing emesis or purgation, recovery will occur within no more than ten days. The orthodox method of Bian Que is to administer Six-Element Decoction (Six-God Pill); for severe cases, moxibustion on Zhongwan (CV12) for thirty cones achieves cure. (This condition involves shallow pathogenic invasion and mild disease, yet many overlook it. In the third year of Yongzheng, during the transition from autumn to winter, everyone suffered from this illness. Heavy doses of warming and tonifying agents might have allowed some to escape death; if medication was administered lightly causing only slight symptom relief, immediate fecal incontinence would ensue. Those who employed clearing and resolving methods combined with Xiao Chai Hu Tang (Minor Bupleurum Decoction) could not revive patients. In the Ningbo and Shaoxing regions, deaths were numerous because they abused cold and cooling herbs; despite repeated errors, they remained unawakened.)
This condition arises primarily from deficiency of Yuan Qi (Original Qi) or exhaustion of the Lower Jiao (Lower Burner) Yang, excessive worry and fear injuring Heart Qi, thereby allowing demonic pathogens to enter through the deficiency, causing coma and interaction with spirits. One should administer Sleep-Saint Powder, apply moxibustion to Juque (CV14) for two hundred cones to naturally extinguish the demonic qi, and then take Ginger and Aconite Decoction for recovery. (How can evil spirits attach to a person? It is the person who attracts them. If one stands upright, possesses a bright heart, does not fail one's sovereign and parents, and feels no shame in solitude, spirits and gods will respect and revere one, leaving no room for evil spirits to take advantage. Only those who are dark, biased, base, dim-witted, and weak are prone to attracting such phenomena, appearing as if possessed by evil spirits, but ultimately these are not evil spirits. Rather, it is due to injury of Zang-Fu Qi leading to the loss of Shen (Spirit) and Hun (Ethereal Soul). Thus, if the Liver is injured, Yi (Intellect) becomes unsettled, and figures in white clothes come to strike; if the Heart is injured, Shen becomes uneasy, and figures in black clothes come to destroy; if the Spleen is injured, Yi is absent, and figures in green clothes come to beat and humiliate; if the Lungs are injured, Po (Corporeal Soul) fails to reside, and figures in red clothes come to bully; if the Kidneys are injured, Zhi (Willpower) becomes hesitant, and figures in yellow clothes come to rebuke and insult. These are all results of injury to Shen-Qi, leading to hallucinations and perceptions that manifest unconsciously in bodily movements and speech, resembling possession. The orthodox treatment lies solely in calming the Shen and Hun, stabilizing the Zhi and Po, examining which Zang-Fu is deficient and tonifying it, and identifying which Zang-Fu is being attacked and controlling it.)
Treatment Cases:
A woman, due to insufficiency of Heart Qi, had youths attaching to her body every night. Examination of the six pulse positions revealed no pathology. I instructed her to receive moxibustion on Shangwan (CV13) for fifty cones. At night, when the ghosts came, they could not approach closer than five chi from the bed. After taking Ginger and Aconite Decoction and Heart-Calming Pill for five days, she recovered.
The wife of a nobleman was possessed by a ghost; various methods proved ineffective. A Daoist priest wrote a Heavenly Physician Talisman and petitioned the Jade Emperor, also without effect. I instructed her to take three qian of Sleep-Saint Powder, apply moxibustion to Juque (CV14) for fifty cones, and further apply moxibustion to Shimen (CV5) for three hundred cones. Upon reaching two hundred cones, the patient opened her eyes normally. After taking Ginger and Aconite Decoction and Heart-Calming Pill for five days, she recovered.
A woman suffering from Xu Lao (Deficiency Consumption) had her Zheng Qi (Upright Qi) nearly depleted and was possessed by a ghost. I used large moxa cones to moxibustion Guanyuan (CV4). She found the pain unbearable, so I had her take three qian of Sleep-Saint Powder, then resumed moxibustion until one hundred and fifty cones, at which point she woke up. Through continued administration of medicine and moxibustion, reaching three hundred cones total, the demonic pathogens departed, and the consumption ailment improved.
