《产宝百问》曰∶妇人脚十趾如热油煎者，此由荣卫气虚，湿毒之气留滞经络，上攻心则心痛，下攻脚则
脚痛，其脚趾如焚。亦香港脚之类，经云热厥者是也。
慎斋按∶妇人足十趾如热油煎，方书但云香港脚之类，方用换腿丸、万灵散、活血丹，从香港脚治法，殊未尽
善。夫诸阳气起于四肢，足之三阳三阴，俱起足趾之端。其热如油煎者，荣卫亏损，阴衰火旺之极，足三阴三
阳经受伤故也，岂但云香港脚而已。法当大剂滋水益阴，乃可救其燎原之焚耳。
《大全》曰∶人禀五行秀气而生，承五脏神气而养，阴阳调和，脏腑强盛，邪魅安得干之。若摄理失节，
血气虚衰，则鬼邪干正，隐蔽而不欲见人，时独言笑，忽时悲泣，是其候也。脉迟伏，或如鸟啄，或绵绵而来，
不知度数，面色不改，亦其候也。
《产宝百问》曰∶人有五脏，有七神。脏气盛则神强，外邪鬼魅不能干犯。若摄理失节，血气虚衰，鬼邪
侵伤，故妇人多与鬼魅交通。其状不欲见人，如有对忤是也。设令宫中人与寡妇，曾夜梦交通，邪气怀惑，久
作瘕，或成鬼胎。
薛立斋曰∶前证多由七情亏损心血，神无所护而然，用安神定志等药，正气复而神自安。若脉来乍大乍小，
乍短乍长，亦是鬼祟，灸鬼哭穴，以患人两手拇指相并，用线扎紧，当合缝处，半肉半甲间，灸七壮。果是邪
祟，病者即乞求免灸，云我自去矣。
慎斋按∶以上三条，序妇人有梦与鬼交之证也。夫人之五脏，各有所藏，心藏神，肝藏魂，肺藏魄，脾藏
意，肾藏精与志。心之血虚，则神无所根据。肝之血虚，则魂无所附。肺之气虚，则魄无所归。脾肾二脏虚，则
意与志恍惚而不能主。神明之官一失，而魂魄已离其体，夜梦鬼邪乘虚，而慌慌若有所见者，即我之魂魄也。岂
真有所谓鬼邪祟魅，与之交感者哉。立斋断以为七情亏损心血，神无所护而然，真发病情之秘者矣。若《准
绳》、《纲目》所载，交接出血，阳道违理，伤丈夫诸证，事近隐曲亵鄙，在病者与医者，似难诊疗，概删之。
《产宝百问》说：妇女十个脚趾像被热油煎灼一样，这是由于营卫之气虚弱，湿毒之气滞留于经络之中，向上攻冲心脏则引起心痛，向下攻冲脚部则导致脚痛，其脚趾感觉如同焚烧一般。这也属于香港脚（足痛风/下肢肿痛）的范畴，医经中所说的“热厥”病就是指的这种情况。
慎斋按语：妇女十个脚趾像被热油煎灼，方书仅说是香港脚一类的病，治疗方剂使用换腿丸、万灵散、活血丹，按照香港脚的治疗方法处理，这并不十分完善。因为诸阳之气起始于四肢，足部的三条阳经和三条阴经，都起始于脚趾的末端。那种热感如油煎一样的症状，是营卫亏损，阴液衰竭而虚火极旺，导致足部三阴三阳经脉受损的缘故，哪里仅仅是香港脚而已呢？治疗方法应当用大剂量的药物滋补肾水、益养阴液，才能挽救这种燎原般的火热之症。
《大全》说：人禀受五行秀气而生，依靠五脏神气来滋养，如果阴阳调和，脏腑强盛，邪魅怎么能干扰人体呢？如果调摄护理失当，血气虚衰，那么鬼邪就会侵犯正气，患者会隐蔽起来不愿见人，有时独自说话发笑，有时突然悲伤哭泣，这是它的征候。脉象迟缓伏匿，或者像鸟啄米一样急促不匀，或者绵绵而来，不知节律，面色没有改变，也是它的征候。
《产宝百问》说：人有五脏，有七神。脏气旺盛则神志强健，外邪鬼魅不能侵犯。如果调摄失当，血气虚衰，鬼邪侵伤身体，所以妇女多会与鬼魅发生性交。其表现是不愿见人，好像与人顶撞冲突一样。假如宫中的宫女与寡妇，曾经夜间梦见与鬼交合，邪气迷惑心神，日久形成瘕聚（腹内结块），或者形成鬼胎。
薛立斋说：上述证候多由七情（喜、怒、忧、思、悲、恐、惊）亏损心血，神志失去保护所致，使用安神定志等药物，正气恢复后神志自然安定。如果脉象忽大忽小，忽短忽长，这也是鬼祟作怪，可以灸治鬼哭穴，让患者将两手拇指并拢，用线扎紧，在穴位处（合缝处，半肉半甲之间）施灸七壮。如果是真正的邪祟，病人就会乞求停止施灸，说：“我自己走了。”
慎斋按语：以上三条，叙述了妇女有梦中与鬼性交的证候。人的五脏，各有所藏，心藏神，肝藏魂，肺藏魄，脾藏意，肾藏精与志。心的血虚，则神志没有依托；肝的血虚，则魂没有依附；肺的气虚，则魄没有归宿；脾肾两脏虚损，则意与志恍惚而不能主宰。神明之官一旦失职，魂魄就已经离开身体，夜间梦境中鬼邪乘虚而入，惊慌失措好像看到了什么，其实那就是我的魂魄罢了。难道真有所谓的鬼邪鬼魅，与我进行交感吗？薛立斋判断为七情亏损心血，神志失去保护所致，真是揭示了病情奥秘的人啊。至于《准绳》、《纲目》所载的，交接时出血，阳道违背常理，损伤丈夫等各种证候，事情近于隐晦曲折、淫秽鄙俗，对于患者和医生来说，似乎难以诊疗，一概删除。
"Chanbao Baiwen" (Hundred Questions on Obstetrics) states: When a woman's ten toes feel as if scalded by hot oil, this is caused by the deficiency of Ying and Wei Qi (Defensive and Nutritive Qi), with damp-toxic qi stagnating in the meridians. If it attacks upward to the Heart, it causes heart pain; if it attacks downward to the feet, it causes foot pain, making the toes feel as if burning. This also belongs to the category of Hong Kong Foot (a traditional term for gouty arthritis or lower limb swelling/pain), which corresponds to "Re Jue" (Heat Jue/Cold Extremities due to Heat) mentioned in medical classics.
Shen Zhai commented: Regarding women whose ten toes feel scalded by hot oil, formularies merely classify it as Hong Kong Foot, prescribing formulas such as Huan Tui Wan (Leg-Changing Pill), Wan Ling San (Ten Thousand Spirits Powder), and Huo Xue Dan (Blood-Invigorating Pellet), treating it according to the methods for Hong Kong Foot. This approach is not entirely adequate. All Yang Qi originates from the four limbs; the three Yang meridians and three Yin meridians of the foot all begin at the tips of the toes. The sensation of heat like scalding oil indicates extreme deficiency of Ying and Wei Qi, exhaustion of Yin fluids leading to hyperactive fire, and injury to the three Yin and three Yang meridians of the foot. It is certainly not just Hong Kong Foot. The treatment method should employ large doses of herbs to nourish Kidney Water and benefit Yin, thereby rescuing the body from this raging fire.
"Daqan" (General Collection) states: Humans are born endowing the exquisite Qi of the Five Elements and nurtured by the spiritual Qi of the Five Zang Organs. If Yin and Yang are harmonious and the Zang-Fu organs are strong, how can evil spirits interfere? However, if regulation and care are improper, leading to blood and Qi deficiency, ghostly evils will invade the righteous Qi. The patient may hide and refuse to see others, sometimes speaking and laughing alone, or suddenly weeping bitterly; these are its signs. The pulse may be slow and deep, or rapid and irregular like a bird pecking, or continuous but without rhythm. The facial color remains unchanged, which is also a sign.
"Chanbao Baiwen" states: Humans have five Zang organs and seven Shen (Spirits). When organ Qi is abundant, the Shen is strong, and external evils and ghosts cannot invade. If regulation is improper, leading to blood and Qi deficiency, ghostly evils invade and injure the body. Therefore, women often engage in sexual intercourse with ghosts. The manifestation is an unwillingness to see people, as if confronting someone. Suppose palace maids or widows have previously dreamed of nocturnal intercourse with ghosts; the evil qi bewitches the mind. Over time, this may form a Jia mass (abdominal mass) or even a Ghost Fetus.
Xue Lizhai stated: The above conditions are mostly caused by Seven Emotions (Joy, Anger, Worry, Pensiveness, Sorrow, Fear, Fright) damaging Heart Blood, leaving the Shen unprotected. Using medicines such as An Shen Ding Zhi (Calm the Spirit and Stabilize the Will) can restore righteous Qi, after which the Shen naturally settles. If the pulse fluctuates between large and small, short and long, this is also attributed to ghostly disturbances. One may moxa the Gui Ku acpoint (Ghost Crying Point). Have the patient join both thumbs tightly together and bind them with thread. Moxa seven moxa cones at the junction where flesh and nail meet. If it is truly a ghostly disturbance, the patient will beg to stop the moxibustion, saying, "I am leaving now."
Shen Zhai commented: The above three passages describe the syndrome of women dreaming of sexual intercourse with ghosts. Each of the five Zang organs stores specific aspects: the Heart stores Shen, the Liver stores Hun (Ethereal Soul), the Lungs store Po (Corporeal Soul), the Spleen stores Yi (Intellect), and the Kidneys store Jing (Essence) and Zhi (Will). If Heart Blood is deficient, the Shen has no foundation; if Liver Blood is deficient, the Hun has no attachment; if Lung Qi is deficient, the Po has no return; if the Spleen and Kidneys are deficient, the Yi and Zhi become vague and unable to govern. Once the official of Spiritual Intelligence fails, the Hun and Po leave the body. At night, when ghostly evils take advantage of the deficiency, the dreamer feels panicked as if seeing something—that is actually one's own Hun and Po. Could there really be ghosts or demons interacting with us? Xue Lizhai judged it as Heart Blood damage due to Seven Emotions, leaving the Shen unprotected; he truly revealed the secrets of the disease's origin. As for the conditions recorded in "Zhunseng" and "Gangmu," such as bleeding during intercourse, abnormal male function, and injuries to men, these matters are too obscure, indecent, and vulgar. They seem difficult to diagnose and treat for both patients and physicians, so they are generally omitted.
