（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。
(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.
