男女交感，乐极精脱而死，切不可惊走下床，男脱则女以口哺送其热气，女脱则男以口
哺送其热气，一连数十口呵之，则必悠悠然阳气重回矣。再以人参附子汤灌之。（送气之法
，先须闭口提丹田之气上来，尽力哺于口中，送于喉去，可救垂绝于俄顷），若贫者不能得
参，急用黄 四两，当归二两，附子五钱，水煎服，亦有生者。
又方∶用人抱起坐之，以人之口气呵其口，又恐不能入喉，急以笔管通其两头，入病患
喉内，使女子呵之，不必皆妻外家也。凡妇人皆可尽力呵之，虽死去亦生。
腰痛，人们都认为是肾脏的疾病，却不知道并非肾病，而是脾脏湿气所致。患者感觉腰间像系着重物，治疗方法应当去除腰部和脐周的湿气，这样腰痛自然消除。白术二两，薏苡仁一两五钱，加水三碗，煎煮成一碗药汤，一次性饮服，服用一次后病症即刻消失，通常以服用两剂为疗程结束。此方虽不直接治疗肾脏，但正是通过调理脾胃来从根本上治疗肾脏相关的问题。

另一个方子：吴茱萸一茶杯量，研磨成粉末，用一杯黄酒拌匀，炒热后摊在油纸上，敷于患处，用布捆扎固定，能立即止痛，如果药凉了，再重新炒热使用。

男女交合时，因快乐过度导致精气脱失而濒死，切不可惊慌逃跑或下床。男性精气脱失，则女性用口向其输送热气；女性精气脱失，则男性用口向其输送热气，连续呵气数十口，阳气必能缓缓回归。然后再用人参附子汤灌服。（送气的方法，必须先闭口提起丹田之气至口中，尽力吹入对方口中，送至喉部，可在顷刻间挽救垂危的生命）。如果贫穷者买不起人参，急用黄芪四两，当归二两，附子五钱，加水煎服，也有救活的案例。
另一个方子：让人抱起患者使其坐起，用人的口气向患者口中呵气，又担心气体不能进入喉部，急忙用笔管贯通两头，插入患者喉内，让女子对着笔管另一端呵气，不必都是妻子的娘家人。凡是妇人都可以尽力呵气，即使已经死亡也能救活。
Lower back pain is often mistakenly attributed to kidney disease, but it is actually caused by dampness in the spleen. Patients may feel as if a heavy weight is tied around their waist. The treatment should focus on removing dampness from the lower back and umbilical region, after which the pain will naturally subside. Use 2 liang of Atractylodis Macrocephalae Rhizoma (Baizhu) and 1.5 qian of Coicis Semen (Yiyiren), add three bowls of water, decoct until one bowl remains, and drink it all at once. The symptoms will disappear after a single dose; typically, two doses are sufficient for a course of treatment. Although this formula does not directly target the kidneys, it effectively treats them by addressing the root cause in the spleen.
Use 1 qian each of Angelicae Sinensis Radix (Danggui), Rehmanniae Radix Praeparata (Shudi), Paeoniae Radix Alba (Baishao), Achyranthis Bidentatae Radix (Niuxi), Dendrobii Caulis (Shihu), and Poria (Fuling); 0.5 qian each of Chuanxiong Rhizome (Chuanxiong), Papaveris Fructus (Mugua), Cinnamomi Cortex (Rougui), Saposhnikoviae Radix (Fangfeng), and Angelicae Pubescentis Radix (Duhuo); 0.3 qian each of Aquilariae Lignum Resinatum (Muxiang) and Glycyrrhizae Radix et Rhizoma Praeparata (Zhigancao); along with one slice of Zingiberis Rhizoma Recens (Jiang). Decoct in water, mix with yellow wine, and take orally. This is effective even for chronic cases lasting many years.
Another prescription: Take one teacup of Evodiae Fructus (Wuzhuyu), grind into powder, mix evenly with one cup of yellow wine, stir-fry until hot, spread on oil paper, apply to the affected area, and bind tightly with cloth. Pain will cease immediately. If the application cools, reheat and reapply.
For conditions involving extreme deficiency of qi and blood leading to hair loss, withered teeth, runny nose, somnolence, excessive phlegm and saliva, lower spine pain, and inability to walk:
Take 4 liang of Cervi Cornu (Lujiao), cut into shavings, stir-fry until yellow, and grind into powder. Take 2 qian with wine. Adding Niuxiu to make pills yields better results. Alternatively, use Qizhi Guzhi Wan (see *Neiwai Beiyong Zhufang*) to eradicate the root cause.
Use 1 qian each of Danggui, Carthami Flos (Honghua), and Niuxi; 0.5 qian of Salviae Miltiorrhizae Radix (Weilingxian); and seven raw Peach Kernels (Taoren). Add one bowl of water, decoct, then add one bowl of yellow vinegar. Take orally for immediate recovery.
Another prescription: Burn the root of Luffa Viminalis (Sigua Gen, also known as Shuigua or Xiangua) to ash while preserving its medicinal properties. Take 2 qian per dose with wine. Effective even for unbearable pain.
Another prescription: Burn the shell of Canavalia Gladiata (Daodou Qiao) to ash, mix with wine, and take orally. Highly effective and miraculous.

During sexual intercourse, death may occur due to exhaustion of essence from excessive pleasure. One must not panic or get out of bed. If the male exhausts his essence, the female should blow warm air into his mouth; if the female exhausts her essence, the male should do the same. Continue blowing dozens of times until yang qi gradually returns. Then administer Renshen Fuzi Tang (Ginseng and Aconite Decoction). (The method of sending breath requires closing the mouth, raising qi from the dantian to the mouth, and blowing forcefully into the other person's mouth towards the throat, which can save a life on the verge of death in an instant). If ginseng is unaffordable, urgently use 4 liang of Astragali Radix (Huangqi), 2 liang of Danggui, and 0.5 liang of Aconiti Lateralis Radix Praeparata (Fuzi), decoct in water and take orally; survival is possible.
Another prescription: Have someone hold the patient in a sitting position. Blow air into the patient's mouth. To ensure the air reaches the throat, insert a pen tube through both ends into the patient's throat and have a woman blow into the other end. It need not be the wife's relative; any woman can attempt this. Even if the patient appears dead, they may be revived.
