【气味】甘温，无毒。
【主治】主惊痫癫矣，鬼疰蛊毒，除寒热，贲豚，五癃，邪气，挛缩。
【核】曰∶豚卵，牡猪之卵子也。小猪多 去卵，故曰豚卵。阴干藏之，勿令败。

两肾之腰子，外肾之阴茎，为豚卵者谬矣。卵者阴器，厥阴经脉之所聚，抵小腹，系舌本，

【本经中品】
【气味】味甘，性温，无毒。
【主治】主要治疗惊痫、癫疾、鬼疰（一种由邪气引起的慢性消耗性疾病）、蛊毒，消除寒热症状，治疗贲豚（气从少腹上冲心胸的病症）、五癃（五种小便不通的病症）、邪气以及肢体挛缩。
【核】曰：豚卵，是公猪的卵子。小猪大多会去除睾丸，所以称为豚卵。将其阴干后收藏，不要让它变质。
【 】曰：豚，指小猪。“豕”是猪的总称。《易经·系辞》中说坎卦象征猪，其性质趋向低下，所以低头喜欢卑湿污秽之处。天将要下雨时，猪就会涉水而行，这是猪躁动的表现。猪前进并涉入水波之中，白色的猪尤其躁动进取，所以它们先进入水中。然而，纯黑色的猪，是猪中较少驯顺的。《说文解字》说：十二地支中的亥对应猪，所以亥字的字形像猪的形状。因为一阴之气生于午月，到亥月时六阴之气完备，人们担心它显得没有阳气，因此“豕”这个字在万物中跟随“豕”部，在气运上跟随“亥”支，它对应水的特性是因为它能充扩同类。母猪叫“牝”，也叫“彘”。《诗经》说：“一发捕获五只小猪”，公猪叫“豯”，也叫“豮”。《诗经》说“一发捕获五只小猪”，《礼记》说用黑猪祭祀，那么豚卵，就是小猪睾丸囊中的卵子。小猪去除睾丸，这样外表肉质好而内部滋味佳，否则会导致混乱且沉溺于群居交配。一个名字叫“豚颠”的原因就在这里。世人废弃不用，却将小猪的儿子（豚儿）、膀胱的尿胞、两肾的腰子、外肾的阴茎，都误称为豚卵，这是错误的。卵子所在的部位是阴器，是厥阴经脉汇聚的地方，向下抵至小腹，向上系连舌根，这正是肾水之宫位的所在。如果肾气躁动，就会顺着水流向上，协同厥阴经的厥逆之气冲犯心脏，这种病名叫贲豚。贲豚，是肾的积病，也是肝气逆乱所致。严重时，重阴导致癫疾，番阴（阴阳交替异常）导致痫疾，阴阳厥逆导致寒热往来；或者肾不能主管阴窍，肝不能疏泄前阴，导致五癃；或者因失去对宗筋的主润作用而导致挛急，失去对关节主利的功能而导致收缩，这些都归属于肾和肝先发生病变而后影响其他脏腑，还没有脱离其类属的，只有豚卵能辅助治疗。
[Shennong Bencao Jing, Middle Category]
【Flavor and Nature】Sweet, warm, non-toxic.
【Indications】Primarily treats sudden fright, epilepsy (Jingxian), manic psychosis (Dianji), Guizhu (a chronic wasting disease caused by evil qi), and Gu poison (poison from insects or parasites). It eliminates alternating chills and fever, Bentun (a condition where Qi rushes upward from the lower abdomen to the chest), Wulong (five types of urinary retention), evil qi, and muscle spasms/contractions.
【Analysis】It is stated: "Tuanluan" refers to the testicles of a male pig. Piglets often have their testicles removed, hence the name "Tuanluan." They should be dried in the shade and stored, ensuring they do not spoil.
【Commentary】It is said: "Tun" refers to a piglet. "Shi" is the general term for pigs. The Commentary on the Appended Lines of the I Ching states that the Kan trigram symbolizes the pig; its nature tends downward, so it lowers its head and prefers low, dirty, and damp places. When rain is about to fall, pigs wade through water, which is a sign of their agitation. As pigs advance into the waves, white pigs are particularly agitated and proactive, thus entering the water first. Therefore, pure black pigs are those among pigs that are less tamed. The Shuowen Jiezi states: In the twelve Earthly Branches, Hai corresponds to the pig, so the character Hai resembles the shape of a pig. Since one Yin qi arises at Wu month, and by Hai month, six Yin qualities are complete, people worry it appears devoid of Yang. Thus, the character Shi follows the radical Shi in objects, and follows the branch Hai in Qi. Its correspondence to Water is because it can expand its own kind. A female pig is called "Pin" or "Zhi." The Book of Songs says: "One shot yields five piglets." A male pig is called "Qi" or "Fen." The Book of Songs says "One shot yields five piglets," and the Book of Rites mentions sacrificing with a black pig. Therefore, "Tuanluan" refers to the testicles within the scrotum of a piglet. Removing the testicles from piglets results in better external meat quality and internal flavor; otherwise, it leads to disorder and indulgence in mating. This is the reason for the alternative name "Tundian." The world discards this substance, mistakenly referring to the offspring of a pig (piglet), the bladder sac, the kidneys (loin meat), and the penis as "Tuanluan," which is erroneous. The location of the testicles is the genital organ, the convergence point of the Jueyin Meridian, reaching down to the lower abdomen and connecting up to the root of the tongue, which is precisely the palace position of Kidney Water. If Kidney Qi becomes agitated, it flows upward, assisting the Jueyin reversal to rush against the Heart. This disease is named Bentun. Bentun is an accumulation in the Kidney and a rebellion of the Liver. In severe cases, excessive Yin leads to Dian (manic psychosis), fluctuating Yin leads to Xian (epilepsy), and Yin-Yang reversal leads to alternating chills and fever. Alternatively, if the Kidney fails to control the Yin orifice, or the Liver fails to drain the anterior Yin, it results in Wulong (urinary retention). Or, losing the ability to moisten the Zongjin (major sinews) leads to spasms, and losing the ability to benefit the joints leads to contraction. All these belong to disorders originating in the Kidney and Liver before affecting other organs. Among those that have not completely separated from their original category to assist in treatment, only Tuanluan serves this purpose.
