阴阳俱虚弱故也。肾主精髓，开窍于阴。今阴虚阳弱，血气不能相荣，故使阴冷也。久
不已，则阴萎弱。
劳伤血气，肤腠虚疏，而受风冷故也。肾主腰脚，肾虚弱则为风邪所乘，风冷客于髀枢

夫劳损之人，体虚易伤风邪。风邪乘虚客于半身，留在肌肤，未即发作，因饮水，水未
消散，即劳于肾，风水相搏，乘虚偏发，风邪留止，血气不行，故半身手足枯细，为偏枯也
肾开窍于阴，若劳伤于肾，肾虚不能荣于阴器，故萎弱也。诊其脉，瞥瞥如羹上肥，阳
气微；连连如蜘蛛丝，阴气衰。阴阳衰微，而风邪入于肾经，故阴不起，或引小腹痛也。

《养生方·导引法》云∶两足指向下柱席，两涌泉相拓，坐两足跟头，两膝头外扒，手
身前向下尽势，七通。去劳损、阴痛、膝冷。
此由风热客于肾经，肾经流于阴器，肾虚不能宣散，故致肿也。

大虚劳损，肾气不足，故阴冷，汗液自泄，风邪乘之，则瘙痒。其汤熨针石，别有正方

《养生方·导引法》云∶偃卧，令两手布膝头，取踵置尻下，以口纳气，腹胀自极，以
鼻出气，七息。除阴下湿，少腹里痛、膝冷不随。
这是因为阴阳两气都虚弱所致。肾主管精髓，其窍穴开于前阴。如今阴虚而阳弱，血与气不能相互滋养，所以导致前阴寒冷。如果久治不愈，就会出现阴茎萎软无力。
这是由于劳损耗伤气血，皮肤腠理空虚疏松，从而受到风邪和寒气的侵袭所致。肾主管腰部和下肢，若肾气虚弱，则容易被风邪乘虚而入，风冷之邪客居于大腿根部（髀枢）之间，所以产生疼痛。
那些因劳损致病的人，身体虚弱容易遭受风邪侵袭。风邪乘虚侵入半身，停留在肌肤之中，并未立即发作；此时若饮水，水液尚未消散，又去劳累肾脏，导致风水二邪相互搏结，乘虚偏侧发作。风邪留滞体内，气血运行不畅，因此出现半身手足枯瘦细小，这就是偏枯病。
肾的窍穴开于前阴，如果肾脏因劳损而受伤，肾虚不能滋养前阴器官，就会导致萎软无力。诊察其脉象，脉来轻浮无根如同羹汤表面的浮油，这是阳气微弱；脉来连绵不断细如蜘蛛丝，这是阴气衰败。阴阳之气都衰微，加上风邪侵入肾经，所以阴茎不能勃起，或者牵引小腹部疼痛。《养生方》中说：水银不能靠近前阴，否则会导致阴茎萎缩缩小。
肾气虚损，被风邪所侵扰，邪气流入肾经，与体内的阴气相互撞击，真气与邪气交争，所以导致前阴疼痛。如果只是受寒，只会感到疼痛；如果夹杂热邪，则会肿胀。关于热敷、熨贴、针刺和砭石治疗，另有专门的方剂，补益调养和导引宣通的方法，现在附在后面。
《养生方·导引法》中说：双足趾向下支撑席子，两个涌泉穴相对接触，坐在双脚脚跟处，双膝向外分开，双手在身前尽力向下伸展，重复七次。可以去除劳损、前阴疼痛和膝盖发冷。
这是由于风热之邪客居于肾经，肾经的热邪流注于前阴器官，肾虚不能宣散邪气，所以导致肿胀。
疝病，是指气机阻滞引起的疼痛。众多的筋脉汇聚于前阴器官。邪气客居于足厥阴肝经和足少阴肾经，与寒气相互搏结，就会导致前阴疼痛、肿胀并发生挛缩。
极度虚损劳伤，肾气不足，所以前阴寒冷，汗液自行外泄，风邪乘虚侵袭，就会引起瘙痒。关于热敷、熨贴、针刺和砭石治疗，另有专门的方剂，补益调养和导引宣通的方法，现在附在后面。
《养生方·导引法》中说：仰卧，让双手分布在膝盖头处，将脚后跟置于臀部下方，用口吸气，使腹部胀满到极点，再用鼻呼气，重复七次呼吸。可以消除前阴潮湿、小腹内部疼痛以及膝盖发冷活动不便。
This is due to the deficiency of both Yin and Yang. The Kidney governs essence and marrow, and its orifice opens at the external genitalia. Now, with Yin deficiency and Yang weakness, Blood and Qi fail to nourish each other, thus causing coldness in the external genitalia. If this persists for a long time without healing, it will lead to impotence (Yin Wei Ruo).
This is caused by labor injury depleting Blood and Qi, making the skin and interstices (Fu Cou) empty and loose, thereby allowing Wind-Cold pathogens to invade. The Kidney governs the waist and legs; when the Kidney is weak, it is easily invaded by Wind pathogens. When Wind-Cold lodges between the hip joints (Bi Shu), pain occurs.
Individuals suffering from labor injury have deficient bodies that are susceptible to Wind pathogens. The Wind pathogen invades half of the body while taking advantage of the deficiency, remaining in the muscles and skin without immediate manifestation. If one drinks water while the fluid has not yet dispersed, and then exerts oneself on the Kidneys, Water and Wind pathogens contend with each other. Taking advantage of the deficiency, they manifest unilaterally. The Wind pathogen remains stagnant, obstructing the flow of Blood and Qi, resulting in withered and thin limbs on one side, known as hemiplegia (Pian Gu).
The Kidney's orifice opens at the external genitalia. If the Kidney is injured by labor, Kidney deficiency fails to nourish the sexual organs, leading to flaccidity and weakness. Upon pulse diagnosis, if the pulse feels light and floating like fat floating on soup (Pie Pie Ru Geng Shang Fei), it indicates weak Yang Qi; if the pulse feels continuous and fine like a spider's thread (Lian Lian Ru Zhi Zhu Si), it indicates declining Yin Qi. With the decline of both Yin and Yang, and Wind pathogens entering the Kidney Meridian, the penis may fail to erect, or there may be pulling pain in the lower abdomen. The *Yang Sheng Fang* states: Mercury should not come near the external genitalia, as it causes the penis to shrink.
When Kidney Qi is damaged and invaded by Wind pathogens, the pathogenic qi flows into the Kidney Meridian and clashes with the body's Yin Qi. The true Qi and pathogenic Qi contend with each other, causing pain in the external genitalia. If only cold is present, there is merely pain; if heat is involved, swelling occurs. Treatments such as hot compresses, moxibustion, acupuncture, and stone therapy have separate specific formulas. Methods for tonification, nourishment, and guidance exercises are attached below.
The *Yang Sheng Fang · Dao Yin Fa* states: Press the toes of both feet downward against the mat, bring the two Yongquan points (KI-1) together, sit on the heels, spread the knees outward, extend both hands forward and downward as far as possible, repeating seven times. This removes labor injury, genital pain, and cold knees.
This is caused by Wind-Heat pathogens lodging in the Kidney Meridian. The heat from the Kidney Meridian flows into the external genitalia. Due to Kidney deficiency, the pathogen cannot be dispersed, resulting in swelling.
Shan disease refers to pain caused by Qi stagnation. Many tendons converge at the external genitalia. When pathogens lodge in the Jueyin and Shaoyin meridians and contend with Cold Qi, it causes pain, swelling, and contraction of the external genitalia.
Severe deficiency and labor injury result in insufficient Kidney Qi, causing coldness in the external genitalia and spontaneous sweating. When Wind pathogens take advantage of this deficiency, itching occurs. Treatments such as hot compresses, moxibustion, acupuncture, and stone therapy have separate specific formulas. Methods for tonification, nourishment, and guidance exercises are attached below.
The *Yang Sheng Fang · Dao Yin Fa* states: Lie supine, place both hands beside the knees, position the heels under the buttocks, inhale through the mouth until the abdomen is fully distended, and exhale through the nose, repeating for seven breaths. This eliminates dampness in the genital area, internal lower abdominal pain, and cold knees with limited mobility.
