（神芎导水丸的组成与用法）：即舟车丸合神芎丸，加槟榔、取虫、芜荑，研为细末，用水泛丸。空腹服用，每次五丸，每日三次。河间先生根据仲景之法制出此方，主治一切水湿为病。戴人云：“十枣汤是泻诸水的上药”，所谓“温药下之”即是此意。如中满腹胀、水气、虫肿、留饮、癖积、气血壅滞不得宣通、风热燥郁、肢体麻痹、走注疼痛、久新疟痢等病，妇人皆令按法治之。病去如扫，故贾同知称为神仙之奇药也。
按娄全善曰：舟车丸乃河间所定。初服五丸，每日三次，如果至快利后，却常服以病去为度。设病愈后极甚者多服，反烦渴不开，转加痛闷。宜初服二丸，每服加大随强弱增损三四岁者三五丸。根据前法加减，至戴人变粒，继以川等物投之。五更当下，种种病出。投下少末再……者病轻者可一二度止，重者五六度方愈。是擒纵卷舒之确，自非老手谙练，有大负荷者焉敢见诸行事？余每亲制进服，强实之人根据戴人治法行之，神效。
（神芎导水丸的另一种加减法）：即神芎丸去芫花、大戟、大枣、轻粉，加郁李仁、芒硝。楼全善评曰：此下诸积之圣药也。诸湿为土，火热能生湿土，故夏热则万物湿润，秋凉则湿复燥干。湿病在阳，而病木乘肝木，是痛下养。
（十枣汤加减方）：即十枣汤加海带、海藻、郁李仁、续随子、商陆根，水煮枣肉为丸，如小豆大。每服五十丸，水下。
（神芎导水丸的具体药物组成与功效）：用黄芩（一两）、黄连、川芎、薄荷（各半两）、大黄（二两）、滑石、黑牵牛（各四两）。治劳瘵停湿、二阳病热郁。河间制治一切热证，其功不可尽述。设或久病热郁，无问瘦痿老弱，并一切证可下者，始自十丸以为度。常服此药，除肠胃积滞，不伤和气，推陈致新，得利便快，并无药燥搔扰，亦不困倦虚损，遂病患心意。或热病下郁色不开。
(Composition and Administration of Shenxiong Daoshui Wan): It is composed of Zhouche Wan (Boat and Cart Pill) combined with Shenxiong Wan, plus Areca Seed (Binglang), Scolopendra (Quchong), and Groundnut Root Bark (Wangyi). These are ground into fine powder and formed into pills using water. Take on an empty stomach, five pills per dose, three times daily. Hejian (Liu Wansu) formulated this prescription based on the methods of Zhongjing (Zhang Zhongjing). It treats all diseases caused by water-dampness. Dairen (Li Dongyuan) stated: "Shizao Tang (Ten Jujube Decoction) is the premier medicine for draining excessive water," which corresponds to the principle of "using warm medicines to purge downwards." It applies to conditions such as abdominal fullness and distension, edema due to water retention, parasitic swelling, retained fluid, phlegm-fluid accumulation, qi-blood stagnation obstructing free flow, wind-heat dryness and depression, limb numbness and paralysis, migrating pain, chronic or acute malaria and dysentery, etc. Women should also be treated according to these methods. The disease is eliminated as if swept away; therefore, Jia Tongzhi called it a miraculous divine drug.
According to Lou Quanshan: Zhouche Wan was standardized by Hejian. Initially take five pills, three times daily. If rapid purgation occurs, continue taking it until the disease is resolved. However, if extremely severe cases take too much after recovery, it may cause irritability, thirst, and lack of relief, worsening pain and oppression. One should initially take two pills, adjusting the dosage up or down by three or four pills based on strength and age (three to five pills for children aged three to four years). Follow the previous method for adjustments. When Dairen changed the form to granules, followed by administration of Chuan... substances. Bowel movement should occur at dawn, expelling various pathogens. For mild cases, one or two doses suffice; for severe cases, five or six doses are needed to cure. This mastery of controlling the treatment's intensity is not something a novice can achieve; only experienced practitioners with substantial capability dare to apply it in practice. I have personally prepared and administered it; when applied to robust individuals following Dairen's methods, it yields miraculous effects.
(Another Modification of Shenxiong Daoshui Wan): It is Shenxiong Wan minus Kansui Root (Yuanhua), Great Euphorbia Root (Daji), Chinese Date (Dazao), and Calomelas (Qingfen), plus Prunus Seed (Yuliren) and Mirabilite (Mangxiao). Lou Quanshan commented: This is the sage medicine for purging various accumulations. All dampness belongs to Earth; fire-heat can generate damp-Earth. Thus, in summer heat, all things are moist; in autumn coolness, dampness dries up again. Dampness affecting the Yang level leads to Wood overacting on Liver Wood, causing pain and requiring downward nourishment/purging.
(Modification of Shizao Tang): It is Shizao Tang plus Kelp (Haidai), Sargassum (Haizao), Prunus Seed (Yuliren), Croton Seed (Xuisui Zi), and Phytolacca Root (Shanglu Gen), boiled with Chinese Date flesh to form pills the size of small beans. Take fifty pills per dose, washed down with water.
(Specific Composition and Efficacy of Shenxiong Daoshui Wan): Use Scutellaria Root (Huangqin, 1 liang), Coptis Rhizome (Huanglian), Ligusticum Rhizome (Chuanxiong), and Mint Leaf (Bohe, each 0.5 liang), Rheum Palmatum Root (Dahuang, 2 liang), Talcum (Huashi), and Black Morning Glory Seed (Heiqianniu, each 4 liang). It treats consumptive disease with retained dampness and heat depression in the Yangming channels. Hejian formulated it to treat all heat syndromes; its merits cannot be fully described. In cases of prolonged heat depression, regardless of whether the patient is emaciated, weak, old, or young, and for any condition suitable for purgation, start with ten pills as a baseline. Regular use of this medicine clears gastrointestinal stagnation without damaging healthy Qi, promotes the elimination of turbidity and generation of freshness, facilitates smooth bowel movements, causes no dryness or irritation from the medicine, nor does it induce fatigue or deficiency. It aligns with the patient's mental state. In cases where heat depression causes facial discoloration or lack of expression...
