（属阴虚，元气不足。）
戴云∶秋初夏末，头痛脚软，食少体热者是也。补中益气汤去柴胡、升麻，加炒黄柏。挟痰，止用南星、
半夏、陈皮之类；或生脉散出千金方。
戴云∶暑风者，夏月卒倒不省人事者是也。有因火者，有因痰者。火，君相二火也；暑，天地二火也；
内外合而炎烁，所以卒倒也。痰者，人身之痰饮也，因暑气入，而鼓激痰饮，塞凝心之窍道，则手足不知动蹑
而卒倒也。此二者皆可吐。内经曰∶火郁则发之。挟火挟痰实者，可用吐法。吐即发散也。量其虚实而吐之，
吐醒后，可用清剂调治之。
戴云∶湿有自外入者，有自内出者，必审其方土之致病
源。东南地下多阴雨地湿，凡受必从外入，多自下起，以重腿香港脚者多。治当汗散；久者，宜疏通渗泄。西北
地高，人多食生冷湿面，或饮酒后，寒气怫郁，湿不能越，作腹皮胀痛，甚则水鼓胀满，或通身浮肿如泥，按
之不起，此皆自内而出也。辨其元气多少，而通利其二便，责其根在内也。此方土内外，亦互相有之，但多少
不同，须对证施治，不可执一。
本草苍术治湿，上下俱可用。
二陈汤加酒芩、羌活、苍术、散风之药，行湿最妙。
内伤∶病退后燥渴不解者，有余热在肺家，可用参苓甘草少许，姜汁冷服；或茶匙挑姜汁与之。虚者可
用人参汤。世之病此者为多，但有挟痰者，有挟外邪者，有热郁于内而发者，皆以补元气为主。看其所挟之病，
而兼用药。
戴元礼说：在夏末秋初之际，出现头痛、脚软、食欲不振、身体发热的症状，就是这种情况。治疗可用补中益气汤去掉柴胡和升麻，加入炒黄柏。如果兼有痰湿，仅使用制南星、半夏、陈皮之类的药物；或者使用出自《千金方》的生脉散。
戴元礼说：所谓“暑风”，是指在夏季突然昏倒、不省人事的症状。有的因为火邪引起，有的因为痰饮引起。这里的“火”，指的是君火和相火；“暑”，指的是天地间的火热之气；内外之火合而为一，炽热灼烧，所以导致突然昏倒。“痰”，是指人体内的痰饮，因暑气侵入，鼓动激荡痰饮，堵塞心窍，导致手足不能随意运动而突然昏倒。这两种情况都可以用吐法治疗。《内经》说：“火郁结则发散之。”对于兼有火邪或痰饮且体质实盛者，可以使用吐法。吐法即是一种发散的方法。需根据患者体质的虚实来决定是否使用吐法，吐醒之后，可以用清热剂进行调理治疗。
戴元礼说：湿邪有从外部侵入的，也有从内部产生的，必须审察当地地理环境致病之源。东南地区地势低洼，多阴雨潮湿，凡是受湿邪侵袭，大多从外部进入，病势多从下部开始，因此患下肢沉重、香港脚（足部肿胀疼痛）的人较多。治疗应当采用发汗散邪的方法；病程久者，宜采用疏通渗泄的方法。西北地区地势高亢，人们多吃生冷、湿面，或在饮酒后，寒气郁结，湿气无法宣越，导致腹部皮肤胀痛，严重甚至出现水鼓胀满，或全身浮肿如泥，按压后凹陷不起，这些都是从内部产生的。辨别其元气的多少，通过通利二便来治疗，追究病根在于内部。这种因地域不同导致的内外湿邪，也往往互相夹杂，只是比例不同，必须辨证施治，不可固执一端。
本草记载苍术可以治疗湿邪，上下部位均可使用。
二陈汤加入酒黄连、羌活、苍术以及祛风药物，行湿效果极佳。
内伤：疾病退去后，仍有燥渴不解的情况，说明有余热残留于肺脏，可使用少量人参、茯苓、甘草，配合姜汁冷服；或者用茶匙挑取姜汁喂服。体质虚弱者可用人参汤。世间患此病的人很多，但有的兼夹痰湿，有的兼夹外邪，有的则是热郁于内而发作，治疗都以补益元气为主。观察其所兼夹的病邪，同时配合用药。
(This syndrome belongs to Yin deficiency and insufficient Yuan Qi [Original Qi].)
Dai Yunli stated: At the end of summer and beginning of autumn, symptoms such as headache, softness of the legs, poor appetite, and body heat are indicative of this condition. The treatment involves Bu Zhong Yi Qi Tang (Tonify the Middle and Augment the Qi Decoction) with Chai Hu (Bupleuri Radix) and Sheng Ma (Cimicifugae Rhizoma) removed, and Chao Huang Bai (Processed Phellodendri Cortex) added. If accompanied by phlegm-dampness, only use herbs such as Zhi Nan Xing (Prepared Arisaematis Rhizoma), Ban Xia (Pinelliae Rhizoma), and Chen Pi (Citri Reticulatae Pericarpium); or alternatively, use Sheng Mai San (Generate the Pulse Powder) from *Qian Jin Fang* (Essential Prescriptions Worth a Thousand Gold).
Dai Yunli stated: What is termed "Shu Feng" [Summerheat Wind] refers to sudden collapse and loss of consciousness during the summer months. Some cases are caused by Fire [Heat], and others by Phlegm. Here, "Fire" refers to Ministerial Fire [Jueyin/Sanjiao fire] and Sovereign Fire [Heart fire]; "Summerheat" refers to the Fire of Heaven and Earth; when internal and external fires combine and scorch, it leads to sudden collapse. "Phlegm" refers to the phlegm-fluids in the human body; due to the invasion of Summerheat Qi, the phlegm-fluids are agitated and stirred, blocking the orifices of the Heart, resulting in the inability to move the limbs and sudden collapse. Both of these conditions can be treated with emesis. The *Nei Jing* (Inner Canon) states: "When Fire is constrained, disperse it." For those with excess patterns complicated by Fire or Phlegm, the emetic method can be used. Emesis is a form of dispersion. One must assess the patient's deficiency or excess before inducing vomiting; after waking up, clear-heat formulas can be used for regulation and treatment.
Dai Yunli stated: Dampness may enter from the exterior or arise from the interior; one must carefully examine the source of disease based on the local geography. In the southeast, where the land is low and there is much rainy and humid weather, dampness usually enters from the exterior and often starts from the lower part of the body; thus, cases of heavy legs and Hong Jiao [Hong Kong Foot/Charley Horse] are common. Treatment should employ sweating to dissipate the pathogen; for chronic cases, methods to unblock and drain dampness are appropriate. In the northwest, where the land is high, people often consume raw, cold foods, damp noodles, or drink alcohol; afterward, Cold Qi becomes constrained, and Dampness cannot diffuse, leading to distension and pain in the abdominal skin, and in severe cases, water drum distension or whole-body edema like mud that does not rise upon pressure. These all arise from the interior. By assessing the amount of Yuan Qi [Original Qi], one treats by promoting urination and defecation, addressing the root cause within. This distinction between external and internal dampness due to geography also involves mutual interaction, differing only in proportion; treatment must be symptomatic and flexible, not rigid.
The Materia Medica records that Cang Zhu (Atractylodis Rhizoma) treats dampness and can be used for both upper and lower parts.
Er Chen Tang (Two-Cured Decoction) combined with Jiu Huang Qin (Scutellariae Radix processed with wine), Qiang Huo (Notopterygii Rhizoma et Radix), Cang Zhu (Atractylodis Rhizoma), and wind-dispersing herbs is excellent for moving dampness.
Internal Injury: After the illness has receded, if dryness and thirst persist, it indicates residual Heat remaining in the Lung system. A small amount of Ren Shen (Ginseng Radix), Fu Ling (Poria), and Gan Cao (Glycyrrhizae Radix et Rhizoma) can be used, taken cold with Ginger Juice (Sheng Jiang Zhi); or administered via a tea spoonful of Ginger Juice. For deficient patients, Ren Shen Tang (Ginseng Decoction) can be used. Many people in the world suffer from this condition, but some have complications of Phlegm, some have complications of External Pathogens, and some have Heat constrained internally causing eruption. In all cases, tonifying Yuan Qi [Original Qi] is the primary principle. One observes the complicating pathogens and incorporates corresponding medications accordingly.
