Zhongshi (Stroke-like syndrome caused by Dampness) refers to the invasion of Dampness within the category of Lei Zhong (Apoplexy-like syndromes). Since Dampness is a Yin pathogenic factor, its onset is gradual rather than sudden. The current sudden occurrence of Zhongshi must be due to a constitution with inherent Spleen and Stomach deficiency, where phlegm-fluid retention has been lingering internally. Upon accidental invasion by external Dampness, it combats with the internal phlegm and rushes upward, causing saliva to surge like a tide and obstructing the airways, leading to sudden fainting and loss of consciousness. This presentation is quite similar to Fengzhong (Wind Stroke), but differs in that the pulse is deep-slow (Chen-Huan), deep-thin (Chen-Xi), or deep-choppy (Chen-Se), and lacks the asymmetry of the face and limbs numbness/paralysis seen in Wind Stroke. This is precisely what Zhu Danxi described as a syndrome of Damp-Heat generating Phlegm, leading to mental cloudiness. It should be treated with Zengsun Weiling Tang (Modified Cinnamon Twig and Atractylodes Macrocephala Decoction), removing Zhu Ling (Polyporus), Ze Xie (Alisma), and Hua Shi (Talcum), and adding Su Zi (Perilla Fruit), Zhi Ban Xia (Prepared Pinellia), Yuan Zhi (Polygala Root), and Chang Pu (Acorus Rhizome). If there is phlegm obstructing the throat with a sound resembling boiling water, there is indeed a risk of sudden transformation of the condition; Suhexiang Wan (Styrax Pill) can be added, taken in two divided doses dissolved in liquid. If the patient regains consciousness after the phlegm subsides, there is hope for recovery; otherwise, it may be incurable.

Maoshi (Superficial invasion by Dampness) is contracted from morning fog and dew, mountain miasma, or continuous rainy days followed by damp evaporation after clearing skies. Initially affected by these pathogens, one feels as if something is covering the head, resulting in a sensation of heaviness in the head as if wrapped, general body discomfort, flaccidity and lassitude of the four limbs, and a soggy-slow (Ru-Huan) pulse. It is appropriate to use Xuan Shu Biao Shi Fa (Method to Disperse and Ventilate Superficial Dampness) to induce slight sweating, following Yu Jiayan’s principle of "valuing slowness over haste," so that the Dampness pathogen is resolved through the exterior and does not penetrate inward. If epigastric fullness/stuffiness, slight fever, scanty sweating, and short red urine occur, this indicates that the Dampness pathogen has entered the interior. Agents for dispersing superficial Dampness are no longer suitable; instead, formulas for promoting urination and draining Dampness should be used, which will naturally hit the mark. Refer to the section on Shang Shi (Injury by Dampness) for further reading.

Jia stated: In summer heat, all things are moist; in autumn coolness, all things are dry. Based on this argument, Damp-Heat syndromes occur in Late Summer, not Autumn, which seems inconsistent with the *Neijing*’s statement "Autumn injury by Dampness." Upon careful consideration, the emphasis of these two sentences lies not in the characters "Summer" and "Autumn," but in "Heat" and "Coolness." Heat steaming generates Dampness, while Coolness overcoming leads to Dryness; this is the natural principle. For instance, during the Liqiu (Start of Autumn) and Chushu (Limit of Heat) solar terms, the heat and steam resemble summer; patients suffer either from Autumn Dampness or Autumn Heat. In fact, Autumn Damp-Heat must also be accompanied by Autumn Heat. Examining the manifestations of Damp-Heat: body heat with sweating, yellow and glossy tongue coating, irritability, thirst, dark urine, and a surging-numerous (Hong-Shu) pulse. These should be treated using Tong Li Zhou Du Fa (Method to Unblock and Drain the Zhou Du [Bladder]). If constipation is present, add Gua Lou (Trichosanthes Fruit) and Xie Bai (Macrostemon Bulb) to open the upper jiao to moisten the lower. If stool remains unpassed and the pulse is solid, large, and forceful, this indicates Damp-Heat combined with accumulation/stagnation; Yuan Ming Fen (Mirabilite) and Zhi Da Huang (Prepared Rhubarb) should be added to the base method for treatment.

A question was raised: Ancients once said that Summer Heat must be accompanied by Dampness; now you say Damp-Heat is accompanied by Summer Heat. Is such a theory valid? The answer is: The Xiao Shu (Minor Heat) solar term occurs after the phase of Ministerial Fire, and the Qi of Da Shu (Major Heat) occurs before the phase of Damp Earth; thus, the ancients taught that "Summer Heat must be accompanied by Dampness." I assert that "Damp-Heat accompanied by Summer Heat" specifically applies to the period from Da Shu to Bai Lu (White Dew). During this time, Damp Earth governs the Qi, Summer Heat gradually recedes, and the Damp command arrives, with Dampness being heavier than Summer Heat; hence it is called Damp-Heat accompanied by Summer Heat. Another question: Zhang Xugu recorded Xue Shengbai’s sections on Wen Shi (Damp-Warmth) and annotated them, collectively referring to it as Shi Re (Damp-Heat). Why do you classify them into separate categories? The answer is: The nature of Dampness is originally Cold; Cold-Dampness can be dispersed with warmth; when fermented into Heat, Damp-Heat can be cleared and unblocked. Only Wen Shi (Damp-Warmth) is neither hot nor cold, making it the most difficult to treat. One must absolutely not confuse Wen Shi with Shi Re; logically, Shi Re and Wen Shi should be listed as two separate categories. Another question: There are many diseases caused by Damp-Heat, why is it briefly mentioned without detail? The answer is: Diseases caused by Dampness are indeed numerous, such as edema/fullness, jaundice, strangury, and turbid urine; these have already been detailed by various ancients in books on miscellaneous diseases. This work specifically discusses seasonal diseases, so repetition is unnecessary.
