巨胜子，非胡麻也。味甘，气温平，无毒。丹溪盛称之。原有功益也。入心、肾二经。
补虚
羸，耐饥渴寒暑，填坚髓骨，益气力，长肌肤，明目轻身，延年不老，益元阳，兴阴茎，尤
生津液，入口即生，与人参相同。其补益之功，不可思议。惟其体尤轻，内实者正无多也，
然亦不必尽是内实者始可用，亦不必尽去其壳，但投之水中，半沉半浮者即可用，将浮者弃
去，取出沉与半沉者，用地黄汁泡之一日，晒干，磨末用为妙。此药宜入丸，而不宜煎汤，
煎则味不能出也。
或问巨胜子胡僧用入桑叶中为丸，果有益乎？此奇方也。先君曾服之，年愈六十，须髯
未白
，后不服此药即白，可见此方之奇。盖巨胜子得桑叶更神者。
或问巨胜子载之《参同契》书中，谓是长生之药。但不知何法服食便可长生？嗟乎！长
生，即
不死之谓也。世人安有服草木之味，而即能长生者乎。夫欲求长生，舍金丹之法，无他药也
。虽然金丹不可得，而巨胜子则易得，胡僧之方虽佳，尚未尽妙。铎有一方，名延景丸，用
巨胜子二斤、熟地一斤、山药一斤、桑叶干者二斤，三月尽采之，晒干为末者佳，老叶不可
用，茯苓三两、薏苡仁三两、芡实三两、淫羊霍半斤、巴戟天一斤、山茱萸半斤、北五味三
两、菟丝子一斤，各为末，蜜为丸。每日白滚水送下五钱，长年可服，如脾气欠健，加白术
一斤。气虚，加人参六两、黄 一斤。阳道欠举，加肉桂三两。此方不寒不热，实延龄妙法
，虽治百岁外，尚可服也。是乃南岳道士所传，谓铎最宜服，可登百岁外。铎用是公之天下
，愿共珍之。
巨胜子，并不是胡麻。味道甘甜，药性温和而平和，没有毒性。朱丹溪非常推崇它。它原本就有补益的功效。归入心、肾二经。
补虚损：能治疗身体消瘦虚弱，使人耐受饥渴及寒暑变化，填补骨髓使骨骼坚固，补充气力，促进肌肤生长，使眼睛明亮、身体轻健，延年益寿而不衰老，增益元阳，增强性功能（兴阴茎），尤其擅长生津液，入口即刻产生津液，功效与人参相同。它的补益功效，不可思议。只是它的质地特别轻，内部实质性的营养成分并不多，然而也不必只有体内充实的人才能使用，也不必一定要去掉外壳，只要投入水中，呈现半沉半浮状态的就可以使用，将漂浮的丢弃，取出下沉和半下沉的药材，用地黄的汁液浸泡一天，晒干后磨成粉末使用最为巧妙。这种药物适宜制成丸剂，不适宜煎煮汤剂，因为煎煮则药味无法析出。
有人问：巨胜子被胡僧放入桑叶中制成丸药服用，果然有益处吗？这是一个奇特的方子。家父曾经服用过，年过六十岁，胡须和眉毛还没有变白，后来不服用此药就变白了，由此可见这个方子的神奇之处。大概是因为巨胜子配合桑叶更加神效。
有人问：巨胜子记载在《参同契》一书中，说是长生的药物。但不知道用什么方法服用就可以长生？唉！所谓长生，就是不死的意思。世人哪有服用草木的味道，就能立即长生的呢？如果想要追求长生，除了金丹之法，没有其他药物了。虽然金丹难以得到，而巨胜子却容易获得，胡僧的方子虽然好，尚且不够精妙。我陈士铎有一个方子，名叫延景丸，使用巨胜子二斤、熟地黄一斤、山药一斤、干燥的桑叶二斤（三月末采集，晒干后磨粉为佳，老叶不可用）、茯苓三两、薏苡仁三两、芡实三两、淫羊藿半斤、巴戟天一斤、山茱萸半斤、北五味子三两、菟丝子一斤，各研为粉末，用蜂蜜制成丸剂。每天用温开水送服五钱，可以常年服用，如果脾气不够健壮，加白术一斤。如果气虚，加人参六两、黄芪一斤。如果阳气不足导致性功能减退，加肉桂三两。这个方子不寒不热，确实是延年益寿的妙法，即使超过百岁的人，还可以服用。这是南岳道士所传授的，说我最适合服用，可以活到百岁之外。我将此方公开于天下，希望大家共同珍视。
Jushengzi (Sesamum indicum seed) is not Sesamum indicum (Huma, 胡麻). It tastes sweet, its nature is warm and neutral, and it is non-toxic. Zhu Danxi highly praised it. It originally possesses tonifying merits. It enters the Heart and Kidney meridians.
Tonifying Deficiency: It treats emaciation and weakness, enables one to endure hunger, thirst, cold, and heat, fills and solidifies the marrow and bones, supplements Qi and strength, promotes skin and flesh growth, brightens the eyes, lightens the body, extends life span without aging, benefits Yuan Yang (Primal Yang), enhances penile erection, and especially generates body fluids. Upon entering the mouth, fluids are generated immediately; its efficacy is similar to that of Renshen (Ginseng Root). Its tonifying merit is inconceivable. However, its texture is particularly light, containing relatively little substantial internal content. Nevertheless, it is not necessary for only those with full interior constitution to use it, nor is it necessary to remove the husk completely. One should simply place it in water; those that float halfway are usable. Discard the floating ones, retrieve the sunken and half-sunken ones, soak them in Rehmanniae Radix Praeparata juice (Dihuang Zhi, 地黄汁) for one day, dry them in the sun, and grind them into powder for optimal use. This herb is suitable for making pills but not for decoction, as decoction prevents the flavor from being extracted.
Someone asked: "The Hu monks mix Jushengzi with Mulberry Leaf (Sangye, 桑叶) to make pills. Is this truly beneficial?" This is a remarkable prescription. My father once took it; after passing sixty years of age, his beard and eyebrows remained unwhite. Later, when he stopped taking this medicine, they turned white. Thus, the wonder of this prescription can be seen. It seems that Jushengzi becomes even more miraculous when combined with Sangye.
Someone asked: "Jushengzi is recorded in the book *Cantong Qi* as a drug for longevity. But what method of administration leads to immortality?" Alas! Longevity implies deathlessness. How could people achieve immediate longevity merely by consuming the taste of herbs and trees? If one seeks longevity, apart from the method of Golden Elixir (Jindan, 金丹), there is no other medicine. Although the Golden Elixir is hard to obtain, Jushengzi is easy to acquire. The Hu monk's prescription, though good, is not yet perfect. I, Chen Shiduo, have a prescription named Yanjing Wan (Longevity Pill), using two jin of Jushengzi, one jin of Shudi (Prepared Rehmannia Root), one jin of Shanyao (Chinese Yam), two jin of dried Sangye (Mulberry Leaf - collected at the end of the third lunar month, best when dried and powdered; old leaves are unusable), three liang of Fuling (Poria), three liang of Yiyiren (Coix Seed), three liang of Qianshi (Euryale Seed), half a jin of YinYanghuo (Epimedium Herb), one jin of Bajitian (Morinda Root), half a jin of Shanzhuyu (Cornus Fruit), three liang of Bei Wuwei Zi (Schisandra Berry), and one jin of Tusizi (Cuscuta Seed). Each is ground into powder, and honey is used to form pills. Take five qian daily with warm boiled water. It can be taken long-term. If Spleen Qi is weak, add one jin of Baizhu (Atractylodes Macrocephala Rhizome). If Qi is deficient, add six liang of Renshen (Ginseng Root) and one jin of Huangqi (Astragalus Root). If Yang energy is insufficient causing erectile dysfunction, add three liang of Rougui (Cinnamon Bark). This prescription is neither cold nor hot; it is indeed a wonderful method for extending lifespan. Even those over one hundred years old may still take it. This was transmitted by Daoists from Mount Nan Yue, who stated that I am most suited to take it and can reach beyond one hundred years. I hereby publish this prescription to the world, wishing everyone to cherish it.
