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.""
