感重而体实者，汗之宜重，麻黄汤；感轻而体虚者，汗之宜轻，香苏散。予尝治伤寒初起，专用香苏散加荆、
防、川芎、秦艽、蔓荆等药，一剂愈；甚则两服，无有不安。其有阴虚、阳虚、挟寒、挟热、兼食而为病者，
即按前法治之。但师古人用药之意，而未尝尽泥其方，随时随症，酌量处治，往往有验。此皆己试之成法，而
与斯世共白之，所以拯灾救患者，莫切乎此，此汗之之道也。又人知发汗退热之法，而不知敛汗退热之法，汗
不出则散之，汗出多则敛也者，非五味、酸枣之谓，其谓致病有因，出汗有由，治得其宜，汗自敛耳。譬如风
伤卫，自汗出者，以桂枝汤和荣卫，祛风邪而汗自止；若热邪传里，令人汗出者，乃热气薰蒸，如釜中吹煮，
水气旁流，非虚也；急用白虎汤清之。若邪已结聚，不大便者，则用承气汤下之，热气退而自收矣。此与伤暑
自汗略同，但暑伤气，为虚邪，只有清补并行之一法，寒伤形为实邪，则清热之外，更有攻下止汗之法也。复
有发散太过，遂至汗多亡阳，身 动欲擗地者，宜用真武汤，此救逆之良药；与中寒冷汗自出者，同类并称，
又与热症汗出者，大相径庭矣。其他少阳症头微汗，或盗汗者，小柴胡汤。水气症头汗出者，小半夏加茯苓
汤。至于虚人自汗盗汗等症，则归脾、补中、八珍、十全、按法而用，委曲寻绎，各尽其妙，而后即安；所谓
汗之必中其经，必得其药，知发而知敛者，此也。”
感受邪气重而体质强壮的人，发汗应当用重剂，如麻黄汤；感受邪气轻而体质虚弱的人，发汗应当用轻剂，如香苏散。我曾经治疗伤寒初起，专门使用香苏散加入荆芥、防风、川芎、秦艽、蔓荆子等药物，服用一剂即可痊愈；病情较重的，服用两剂，没有不平安的。那些有阴虚、阳虚、挟寒、挟热、兼食积致病的情况，就按照前面的方法治疗。只是学习古人用药的意旨，而不曾完全拘泥于古方，根据时间和症状，斟酌处理，往往有效。这些都是我自己验证过的成熟方法，并向世人公开，用来拯救灾难和救治患者的，没有比这更迫切的了，这就是发汗的道理。另外，人们只知道发汗退热的办法，却不知道敛汗退热的办法，汗不出则发散，汗出多则收敛，这并不是指五味子、酸枣仁这类药，而是说致病有原因，出汗有缘由，治疗得当，汗自然收敛。比如风邪伤及卫分，导致自汗出的，用桂枝汤调和营卫，祛除风邪而汗自然停止；如果热邪传入里部，导致人出汗的，那是热气熏蒸，像锅下面吹火煮东西，水气从旁边流出，这不是虚证；急忙用白虎汤清解。如果邪气已经结聚，大便不通的，就用承气汤攻下，热气消退后汗自然就停止了。这与伤暑导致的自汗大致相同，但暑邪伤气，属于虚邪，只有清热与补益并行的方法，寒邪伤形属于实邪，则在清热之外，还有攻下止汗的方法。又有因为发散太过，以至于汗多亡阳，身体震颤想要趴在地上的，适宜用真武汤，这是救逆的良药；这与中寒冷汗自出的情况，同类并称，又与热症出汗的情况，大相径庭了。其他的少阳症头微汗，或者盗汗的，用小柴胡汤。水气症头汗出的，用小半夏加茯苓汤。至于虚人自汗盗汗等症状，则归脾汤、补中益气汤、八珍汤、十全大补汤，按照法则使用，曲折寻绎，各尽其妙，然后才能平安；所谓发汗必须中经，必须得到药效，知道发汗也知道敛汗，就是这个道理。”
For those with heavy pathogenic invasion and strong constitution, sweating therapy should be heavy, such as Mahuang Tang (Ephedra Decoction); for those with light pathogenic invasion and weak constitution, sweating therapy should be light, such as Xiangsu San (Fragrant Perilla Powder). I once treated early-stage Shanghan (Cold Damage) exclusively using Xiangsu San added with Jingjie (Schizonepetae Herba), Fangfeng (Saposhnikoviae Radix), Chuanxiong (Ligustici Chuanxiong Rhizoma), Qinjiao (Gentianae Macrophyllae Radix), and Manjingzi (Vittariae Spora), resulting in cure after one dose; even in severe cases, two doses ensured recovery without exception. For conditions involving Yin deficiency, Yang deficiency, cold retention, heat retention, or food stagnation, one should follow the aforementioned methods. The key is to learn from the intent of ancient physicians' prescriptions without rigidly adhering to their formulas, adjusting treatment according to time and symptoms, which often yields effective results. These are proven methods tested by myself, shared with the world to alleviate disasters and save lives, representing the essence of sweating therapy. Furthermore, while people know the method of sweating to reduce fever, they do not know the method of astringing sweat to reduce fever. "If sweat does not come out, disperse it; if sweat comes out excessively, astringe it." This does not refer merely to Wuweizi (Schisandrae Chinensis Fructus) or Suanzaoren (Ziziphi Spinosae Semen), but implies that since disease has causes and sweating has origins, proper treatment will naturally lead to the cessation of sweating. For instance, when Wind pathogen damages the Wei (Defensive) level causing spontaneous sweating, Guizhi Tang (Cinnamon Twig Decoction) harmonizes Ying (Nutritive) and Wei levels, dispels Wind pathogen, and sweat stops naturally. If Heat pathogen transmits to the interior causing sweating, it is due to heat steaming, like water vapor escaping from a pot being heated, which is not a deficiency syndrome; one should urgently use Baihu Tang (White Tiger Decoction) to clear the heat. If pathogens have aggregated causing constipation, then Chengqi Tang (Purgative Decoction) should be used to purge; once heat recedes, sweating ceases naturally. This is slightly similar to spontaneous sweating caused by Summerheat injury, but Summerheat damages Qi and is a deficiency pathogen, allowing only for simultaneous clearing and tonifying methods. Cold damages the Form and is an excess pathogen, offering not only clearing methods but also purgative methods to stop sweating. In cases where excessive dispersion leads to excessive sweating and loss of Yang, manifesting as tremors and a desire to lie prostrate on the ground, Zhenwu Tang (True Warrior Decoction) is appropriate, serving as a potent medicine for rescuing deviations; this is classified similarly to spontaneous sweating from cold invasion, yet vastly different from sweating in heat syndromes. For other Shaoyang (Lesser Yang) syndromes with slight head sweating or night sweats, Xiaochaihu Tang (Minor Bupleurum Decoction) is used. For Shuiqi (Water-Qi) syndromes with head sweating, Xiao Banxia Jia Fuling Tang (Minor Pinellia Formula with Poria) is used. Regarding spontaneous and night sweats in deficient individuals, Guipi Tang (Restore the Spleen Decoction), Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction), Bazhen Tang (Eight Treasure Decoction), and Shiquan Dabu Tang (Ten Great Tonics Decoction) are applied according to principles; through careful analysis, each achieves its efficacy, leading to peace. This is what is meant by: "Sweating must penetrate the meridians, must achieve the medicinal effect, knowing both how to induce sweating and how to astringe it.""
