多吞也。
或问童便，治吐血甚神，不识可长服否？曰∶童便可暂饮，而不可久服也。虽曰服寒凉，
百
不一生，服童便，百不一死，然童便气凉，多服未免损胃。
或问童便而煎熬秋石，毕竟何者为佳？夫秋石阴阳之炼不同，以阴炼者为第一。但阴炼
气臭
，不若阳炼之无气臭也。然而阴炼得法，实不臭也。我有一法传世，取童便，十五岁以下者
俱可用。每一桶，用水二桶合之，盛于缸内，上用净布铺在缸上，下用竹架之，不使布之沉
底，露一宿，取布晒于烈日之下，布上即结成霜，以鹅翎扫之，即成秋石矣。但布须浮于童
便水上，不可使其竟沉，要布湿而又不干为妙。一桶童便，可取秋石二两。盖童便得水，其
性反浮，又得水则尽化去其臭气。非异人之传，安得此异法哉。凡童便，积旬日皆可用，惟
一合井水，必须一日即取其霜，久则无用也。
或问人有服自己之小便者，名曰反元汤，亦有
益乎？夫吐血之症，其气必逆，用反元汤，以逆而平其逆也，服之有功。倘未尝失血，其气
原无逆症，服之反致动逆，与童便之功，实有不同耳。
胎发，是血液初生的嫩芽。年老体衰之人得到它，能很好地补益衰退枯竭的元气。至于血余（即人发），补阴效果非常迅速，各种出血病症服用后即刻止血。其余《神农本草经》中记载的功效，没有见到其疗效。凡是用胎发，都必须洗净，烧成炭灰但保留药性，调入汤剂中服用。因为头发的味道苦，性质温，只有益处没有害处，所以取用它作为止血救急的药物。
童便（童子尿），气味凉，无毒。清澈透明的质量最好。能祛除虚劳发热咳嗽，止住鼻出血和吐血，治疗跌打损伤，疗治产后败血攻心。难产、胎盘不下，毒蛇咬伤、狗咬伤，都可以用它治疗。
秋石，是将童便经过煎熬提炼法制炼而成的。不分男女，服用都有益处。它能滋补肾水，返本还元，滋养丹田，归根复命，调和五脏，润泽三焦，消除咳逆产生的浓稠痰液，退去骨蒸邪热。对于积聚形成的坚硬肿块可以使用，对于鼓胀病可以代替盐来品尝。能明目清心，延年益寿。这两种药，治病确实很好，正所谓“臭腐化为神奇”。但是秋石可以多用，而童便不宜大量吞服。
有人问童便治疗吐血非常神效，不知道是否可以长期服用？回答说：童便可以暂时饮用，但不能长期服用。虽然有人说服用寒凉药物的人百不活一个，但服用童便的人百不死一个，然而童便性质凉，多服难免损伤胃气。
有人问用童便煎熬制成秋石，究竟哪种方法更好？秋石的炼制有阴阳之分，以阴炼法为第一。但是阴炼法气味臭，不如阳炼法没有臭味。然而如果阴炼法掌握得当，实际上并不臭。我有一种传世的方法，取十五岁以下的童便均可使用。每一桶童便，加入两桶清水混合，盛在缸内，上面用干净的布铺在缸口，下面用竹架支撑，不让布沉到底部，露天放置一夜，取出布在烈日下晾晒，布上就会结成霜状物，用鹅毛扫下来，就成为了秋石。但是布必须浮在童便水面上，不能让它完全沉下去，要布湿润但不干涸为妙。一桶童便，可以取得二两秋石。因为童便遇到水，其性质反而上浮，又因为得水则完全化去了臭味。这不是异人的传授，怎么能得到这种奇异的方法呢。凡是积存了十天的童便都可以使用，只有一合井水，必须一天之内取其霜，时间久了就没有用了。
有人问有人服用自己的小便，名叫反元汤，也有益处吗？回答是：吐血的病症，其气机必然上逆，使用反元汤，是以逆治逆来平抑上逆之气，服用有效。倘若没有失血，气机原本没有上逆的症状，服用反而会导致气机逆乱，这与童便的功效，确实有所不同。
Tai Fa (Fetal Hair) is the tender sprout of blood. For the elderly, obtaining it greatly tonifies decline and depletion. As for Xue Yu (Human Hair), its effect on nourishing Yin is very swift; for various bleeding disorders, taking it stops bleeding immediately. The other effects recorded in *Ben Jing* (Shennong's Classic of Materia Medica) have not been seen to be effective. In all cases, it must be washed clean, burned to ash while retaining its nature, and taken mixed with decoctions. Since hair tastes bitter and has a warm nature, it benefits without harm, thus it is used as an ingredient for stopping bleeding and saving emergencies.
Tong Bian (Child Urine) has a cool nature and is non-toxic. Those that are clear and transparent are of good quality. It dispels consumption fever and cough, stops epistaxis and hematemesis, treats traumatic injuries, and cures postpartum敗血 (retained blood attacking the heart). It can also treat difficult labor, retained placenta, snake bites, and dog bites.
Qiu Shi (Autumn Salt) is refined from Tong Bian through boiling and evaporation methods. It is beneficial regardless of gender. It nourishes Kidney Water, restores one's original state, nourishes the Dantian, returns to the root and restores life, harmonizes the Five Zang organs, moistens the San Jiao (Triple Burner), eliminates thick phlegm caused by rebellious Qi, and dissipates bone-stealing pathogenic heat. It can be used for hard accumulations and masses, and can replace salt for those suffering from abdominal distension (Gu Zhang). It brightens the eyes, clears the Heart, prolongs life, and promotes longevity. These two substances are truly excellent for treating diseases, embodying the saying that "the foul and rotten produce the miraculous." However, Qiu Shi can be used in larger doses, whereas Tong Bian should not be swallowed in large amounts.
Someone asked: "Tong Bian is miraculous for treating hematemesis; can it be taken long-term?" The answer is: "Tong Bian can be drunk temporarily but not for a long time. Although it is said that those who take cold-cooling herbs rarely survive, those who take Tong Bian rarely die. However, since Tong Bian is cool in nature, excessive use inevitably damages the Stomach Qi."
Someone asked: "When refining Qiu Shi from Tong Bian, which method is better? The refinement of Qiu Shi differs by Yin and Yang methods; the Yin-refined version is considered the best. But the Yin-refined version has a foul odor, unlike the Yang-refined version which lacks this odor. However, if the Yin method is practiced correctly, it actually does not smell. I have a method passed down through generations: Take Tong Bian from children under fifteen years old. For every bucket of urine, mix it with two buckets of water, place it in a vat, cover the top with clean cloth, and support the cloth with a bamboo frame so it does not sink to the bottom. Leave it exposed overnight. Take the cloth and dry it in the scorching sun; frost will form on the cloth. Sweep it off with a goose feather, and you have Qiu Shi. The cloth must float on the surface of the urine, not sink completely; it should be wet but not dry. One bucket of urine yields two taels of Qiu Shi. When urine meets water, its nature tends to rise, and the water completely dissolves the foul odor. This is not a transmission from an extraordinary person; how else could such a unique method be obtained? Any Tong Bian accumulated for ten days can be used. Only well water must have its 'frost' collected within one day; otherwise, it becomes useless."
Someone asked: "Some people drink their own urine, called Fan Yuan Tang (Reverse Origin Decoction); is it also beneficial?" The answer is: "In cases of hematemesis, the Qi must be rebellious. Using Fan Yuan Tang uses rebellion to calm rebellion, which is effective. If there has been no blood loss, and the Qi originally has no rebellious symptoms, taking it may instead induce rebellion. Thus, its effect is truly different from that of Tong Bian."
