《千金方》精极类用韭子以治遗精、梦失、小便白浊者，盖九方焉，而单用韭子者居其
半。夫韭子辛热物耳，何孙思邈取之深也？昆谓用之以治便浊者，用其辛热之气，燔其湿土，
使蒸溽上行而不下，乃釜底加薪之法，益火之原以消阴翳也。用之以治遗精者，用其辛热之
气以壮真阳，使之涵乎阴精而不漏，乃益土防水之法，卫外而为固也。凡此方外不传之秘，
惟可与知者道耳。
叙曰∶有因而自汗，非病也，所谓阳之汗以天地之雨名之，乃阴阳和而雨泽降也。惟无
因而自汗，则为病矣，宜以甘剂补之。今考古人四方，率甘剂耳。
黄 （炙） 防风（各一两） 白术（二两）
共为末。每服三钱。
气虚自汗者，此方主之。
自汗者，无因而自汗也。常人不自汗者，由卫气固卫于外，津液不得走泄，所谓阳在外
，阴之卫也。卫气一亏，则不足以固津液，而自渗泄矣，此自汗之由也。白术、黄 、所以
益气。然甘者性缓，不能速达于表，故佐之以防风。东垣有言，黄 得防风而功愈大，乃相
畏而相使者也。是自汗也，与伤风自汗不同，伤风自汗，责之邪气实。杂证自汗，责之正气
虚。虚实不同，攻补亦异，临证者宜详别之。

人参、黄 、白术、茯苓、甘草、防风、肉桂，实表气而止自汗；当归、川芎、熟 、

The *Qianjin Fang* (Prescriptions Worth a Thousand Gold) exquisitely employs the seed of Allium tuberosum (Jiuzi, 韭子) to treat spermatorrhea (Yijing, 遗精), nocturnal emission with loss of essence (Mengshi, 梦失), and turbid urine (Xiaobian Baizhuo, 小便白浊). Among them, there are nine formulas in total, and those using Jiuzi alone account for half. Jiuzi is merely a pungent and hot substance; why did Sun Simiao value it so highly? Kun believes that using it to treat turbid urine relies on its pungent and hot qi to "burn" damp-earth, causing moisture to evaporate upward rather than flow downward. This is akin to adding firewood to the bottom of a pot, namely, supplementing the source of fire to dissipate yin shadows (Yihuo zhiyuan yi xiao yinyi, 益火之原以消阴翳). Using it to treat spermatorrhea relies on its pungent and hot qi to strengthen true yang (Zhenyang, 真阳), enabling it to contain yin essence without leakage. This is like reinforcing the earth to prevent water damage, protecting the exterior and maintaining solidity. These secret methods of external formulas can only be discussed with those who understand.
Preface: Spontaneous sweating caused by a specific factor is not a disease; this is referred to as "sweat of yang," named after the rain of heaven and earth, representing the harmony of yin and yang leading to the descent of nourishing rain. Only spontaneous sweating without any cause constitutes a disease, which should be treated with sweet-tonifying agents. Examining the four ancient formulas, they are predominantly sweet-natured preparations.

This formula governs spontaneous sweating due to qi deficiency.
Spontaneous sweating refers to sweating without an apparent cause. Normal individuals do not sweat spontaneously because Wei Qi (Defensive Qi, 卫气) secures the exterior, preventing body fluids from leaking out. This is described as "Yang on the outside serves as the guard for Yin." Once Wei Qi is deficient, it fails to secure body fluids, leading to spontaneous seepage; this is the origin of spontaneous sweating. Baizhu and Huangqi are used to tonify qi. However, sweet substances have a slow nature and cannot quickly reach the exterior, so Fangfeng is added as an assistant. Dongyuan stated, "When Huangqi is combined with Fangfeng, its efficacy increases greatly"; they mutually restrain yet mutually assist each other. Thus, this type of spontaneous sweating differs from that caused by wind-cold invasion. In wind-cold spontaneous sweating, the issue lies in excess pathogenic factors; in miscellaneous disease spontaneous sweating, the issue lies in deficiency of healthy qi. Since deficiency and excess differ, attack and tonification methods also vary. Clinicians must distinguish them carefully.

This formula governs spontaneous sweating due to dual deficiency of qi and blood.
Renshen, Huangqi, Baizhu, Fuling, Gancao, and Fangfeng solidify the exterior qi and stop spontaneous sweating; Danggui, Chuanxiong, Shudihuang, Roucongrong, Shanzhuyu, and Wuweizi generate body fluids and gather yin qi. This is a formula that tonifies both qi and blood.
