《外台》方 治伤寒八九日，至十余日，大烦渴作热，三焦有疮慝下利，或张口
吐舌，目烂口疮，不识人。用此除热毒止痢。
龙骨半斤，水一斗，煮四升，沉之井底，冷服五合，渐渐进之。
《肘后方》 治热病下利欲死者。
龙骨半斤，研，水一斗，煮取五升，候极冷稍饮，得汗即愈效。
又治久利休息不止者。
龙骨四两打碎，水五升，煮取二升半，分五服冷冻饮料。仍以米饮和丸，每服十丸。
按∶三方并用龙骨水煎冷服，盖以冷除热，而以涩固脱尔。
驻车丸 治一切下痢，无问冷热。
阿胶（十五两，捣碎，蛤粉炒成珠，以醋四升熬成膏） 当归（十五两） 川黄连（三十两
，去须） 炮干姜（十两）
上为末，同阿胶膏，杵成丸梧子大，每服三十丸，食前米饮下。日三。
凡蕴热血痢，里急而痛甚，虽已疏通荡涤，然其痛不减者，非热亦非积也。营血亏少，
阳刚胜阴故尔。用药当以血药为佐，营血一调，其痛立止矣。
梦遗精滑，虽皆属火，而有心肾之异。动于心者，神摇于上，则精遗于下也。不必治肾
，但
清其心而梦自已。盖精之藏贮虽在肾，而精之主宰则在心，是以少年伶俐之人，多有此病，
而田野愚鲁之人，无患此者。总由心之动静而已。动于肾者，壮年气盛，久节淫欲，经络壅
热，精乃不固，经所谓阳强不能密，阴气乃绝是也。而此病复有二∶有出于木者，有出于水
者，以二脏皆有相火故也。宜分别治之。又有脾胃湿热下流，肾经精气不清而遗者，得之醇
酒浓味过多也。《直指》所谓心肾之外，又有脾精不禁，小便漏浊，手足乏力，腰背酸痛，
当用苍术等剂，以敛脾精。敛脾谓何？精生于谷也。
《外台秘要》方：治疗伤寒病经过八九日，甚至十余日，出现极度烦躁、口渴、发热，三焦有疮毒邪气导致下利，或者张口吐舌、眼睛溃烂、口腔生疮、神志不清不认识人的症状。使用此方清除热毒并止住痢疾。
龙骨半斤，用水一斗，煮至四升，将其沉入井底冷却，每次冷服五合，逐渐增加剂量服用。
《肘后备急方》：治疗热病导致下利，病情危重欲死者。
龙骨半斤，研成粉末，用水一斗，煮取五升，等待极冷后少量饮用，出汗后即痊愈见效。
又治疗久痢休息痢不止的患者。
龙骨四两打碎，用水五升，煮取二升半，分五次服用，需冷冻后饮用。另外将龙骨粉末用米汤调和制成丸药，每次服用十丸。
按语：以上三方均使用龙骨水煎剂冷服，大概是以冷制热，并以收敛固涩防止脱失的作用。
驻车丸：治疗各种下痢，不分寒证或热证。
阿胶（十五两，捣碎，用蛤粉炒成珠状，再用醋四升熬成膏） 当归（十五两） 川黄连（三十两，去除须根） 炮干姜（十两）
以上药材研为细末，与阿胶膏混合，杵捣制成梧桐子大小的丸药，每次服用三十丸，饭前用米汤送服。每日三次。
凡是蕴结热血导致的血痢，伴有里急后重且疼痛剧烈，虽然已经通过疏通荡涤的方法治疗，但疼痛仍未减轻的，这不是热邪也不是积滞所致。而是营血亏少，阳气刚盛压制阴气造成的。用药应当以补血药作为辅助，一旦营血调和，疼痛立即停止。
梦遗和精滑，虽然都属于火证，但有心脏和肾脏的区别。由心引起的，是心神在上动摇，导致精气在下遗泄。不必治疗肾脏，只需清心安神，梦境自然消失。因为精气的贮藏虽在肾，但精气的主宰在心，所以少年聪明伶俐的人，多有此病，而田野间愚钝朴实的人，没有这种患病的。总归是由心的动静决定的。由肾引起的，是壮年人气血旺盛，长期节制房事，导致经络壅滞生热，精气不固，这就是经书所说的“阳强不能密，阴气乃绝”。而这种病又有两种：一种出于肝（木），一种出于肾（水），因为肝肾两脏都有相火的原因。应当分别治疗。又有因脾胃湿热下注，导致肾经精气不清而遗精的，这是由于过多饮用美酒和食用浓味厚味食物造成的。《直指方》所说的心肾之外，还有脾精不禁，小便漏浊，手足乏力，腰背酸痛的情况，应当使用苍术等药剂，来收敛脾精。什么叫收敛脾精？因为精气是由谷物化生的。
The formula from *Waitai Mi Yao* (Secrets of the Outer Palace): Treats Shanghan (Cold Damage) disease persisting for eight or nine days, up to ten or more days, presenting with severe restlessness, thirst, and fever; sanjiao (Triple Burner) has sores and hidden pathogens causing diarrhea; or symptoms such as opening the mouth and protruding the tongue, ulcerated eyes, oral ulcers, and inability to recognize people. This formula is used to eliminate heat toxins and stop dysentery.
Longgu (Fossilized Bones, 30g), water 10 dou (approx. 2L), decoct until 4 sheng (approx. 800ml) remain. Submerge in a well to cool, take 5 he (approx. 100ml) cold, gradually increasing the dose.
The formula from *Zhouhou Beiji Fang* (Handbook of Prescriptions for Emergencies): Treats heat diseases causing severe diarrhea bordering on death.
Longgu (Fossilized Bones, 30g), powdered, water 10 dou (approx. 2L), decoct to obtain 5 sheng (approx. 1L). Wait until extremely cold, then drink in small amounts. Recovery occurs with sweating.
Also treats chronic intermittent dysentery that does not cease.
Longgu (Fossilized Bones, 15g), crushed, water 5 sheng (approx. 1L), decoct to obtain 2.5 sheng (approx. 500ml). Divide into five doses, drink after freezing. Additionally, mix Longgu powder with rice water to form pills, taking ten pills per dose.
Commentary: All three formulas use Longgu (Fossilized Bones) decocted in water and taken cold, presumably using cold to counteract heat and astringency to prevent collapse.
Zhuche Wan (Park-the-Cart Pill): Treats all types of dysentery, regardless of cold or heat patterns.
Ejiao (Donkey-Hide Gelatin, 75g), crushed, stir-fried with clam shell powder until granular, then simmered with 4 sheng (approx. 800ml) of vinegar to form a paste. Danggui (Angelicae Sinensis Radix, 75g). Huanglian (Coptidis Rhizoma, 150g), remove rootlets. Ganjiang (Zingiberis Rhizoma Praeparatum, 50g), processed.
Grind the above herbs into fine powder, mix with the Ejiao paste, and pound into pills the size of wutong seeds. Take thirty pills per dose before meals, administered with rice water. Three times daily.
In cases of bloody dysentery caused by accumulated blood-heat, characterized by tenesmus and severe pain, if the pain persists despite purgation and cleansing, it is neither due to heat nor accumulation. It results from deficiency of ying-blood (nutritive blood) where yang-gang overcomes yin. Medication should be assisted with blood-nourishing herbs; once ying-blood is regulated, the pain will cease immediately.
Nocturnal emission and spermatorrhea, although both attributed to fire, differ in their involvement of the heart and kidney. When originating from the heart, spirit fluctuates upward, causing essence to leak downward. There is no need to treat the kidney; simply clear the heart, and the dreams will cease naturally. Although essence is stored in the kidney, its governance lies in the heart. Therefore, clever youths often suffer from this condition, while rustic peasants do not. It ultimately depends on the movement and stillness of the heart. When originating from the kidney, vigorous young men with abundant qi, who have long abstained from sexual activity, may experience congestion and heat in the meridians, leading to insecure essence. This corresponds to the classic saying: "When yang is excessive and cannot secure, yin qi is exhausted." This condition further divides into two types: one arising from wood (liver) and one from water (kidney), because both zang-organs contain ministerial fire. They should be treated separately. Another type arises from damp-heat in the spleen and stomach flowing downward, causing unclear essence in the kidney meridian, resulting from excessive consumption of rich wine and heavy flavors. As stated in *Zhizhi Fang*: Besides the heart and kidney, there is also involuntary leakage of spleen essence, cloudy urine, weakness in hands and feet, and soreness/pain in the lower back. One should use formulas containing Cangzhu (Atractylodis Rhizoma) to astringe spleen essence. What is meant by astringing spleen essence? Essence is generated from grain.
