暑邪分为阴暑和阳暑两种，必须加以辨别。人如果在凉亭水榭中居住，整天吹着风凉，喜欢吃爽口的冷茶冷饮，会导致阳气闭塞。其病症表现为怕风、发热重、出汗少、脉象沉滞，或者出现腹痛、呕吐、腹泻，这是夏季的阴证，不能称之为伤寒，而应命名为阴暑。前人治疗这类病症，多用大顺散、理中汤，病情轻的则用平胃散。我嫌弃干姜、肉桂的药性过于猛烈，治病必须先考虑当年的气候特点，不要损伤人体的自然和谐之气，这也是要紧之处。于是我自己配制了一方剂，名为胜湿和中汤，药物包括苏叶（如果恶寒明显则使用）、半夏、茯苓、陈皮、炙甘草（这四味药组成二陈汤，用于消除痰湿、胜除湿邪）、厚朴、神曲（温中焦、消食导滞）。如果确实看到患者指甲呈现灰色，才可以加入淡附子、干姜各几分。
阳暑是在路途奔波或住在简陋房舍时得的病，虽然劳逸情况不同，但受病的机理是一样的。暑邪是无形的，从口鼻吸入体内，暑邪伤害人气分，所以会出现气短、脉虚；暑邪先伤心，所以会出现心烦、睡眠少、多汗（因为心主液），或者身体发热、四肢无力、口渴想喝冷冻饮料、小便颜色红赤且浑浊。即使六脉都虚细，总体上适宜清解暑热、利除湿气，滑石、淡竹叶、黄芩、黄连、茯苓、薏苡仁之类的药物，都可以选用，再佐以补气的药物，人参白虎汤、清暑益气汤等方剂，都可以参考使用。
有一个邻居家的孩子，年龄十三四岁，面色白，身体虚弱。当时正值三伏天，他出去到外塾读书，白天烈日炎炎，人们大多去汲取井泉水饮用，邻家孩子也喝了两杯，结果就不能去上学了，眼睛瞪大、神情呆滞，萎靡不振地躺在床上。他的父亲兄长请人针刺少商穴，放出少许紫血，接着服用痧药，直到下日辰刻（下午7-9点），邀请我去诊视。此时六脉已经摸不到了，指甲全部变成灰色。我说：这是伏天中寒的病症，也就是所谓的阴暑，如果服用附子理中汤，或许还能救活，但现在已经来不及了。过了中午就去世了。
另一个人从路途奔波回家后，腹痛想吐却吐不出来，想泻却泻不出来，这叫干霍乱，又名搅肠痧，适宜用炒盐冲开水，待温度适宜时饮用并探喉催吐；或者用瓷盘蘸香油在胸背部广泛刮痧，使脏腑气机通畅，能够吐能泻，这样就无妨了。这个人不知道治疗方法，只喝了一碗老姜汤就死了。这属于阳暑范畴。
Summerheat pathogenic factors are divided into two types: Yin Summerheat and Yang Summerheat, which must be distinguished. When people reside in cool pavilions or water-side structures, exposed to wind and coolness all day, and enjoy eating refreshing cold teas and drinks, their Yang Qi becomes obstructed. The resulting illness presents with aversion to wind, high fever, scanty sweating, and a deep, sluggish pulse, or may manifest as abdominal pain, vomiting, and diarrhea. This is a Yin syndrome occurring in summer; it should not be called Cold Damage (Shanghan), but rather named Yin Summerheat. Predecessors treated such conditions primarily with Dashun San (Greatly Smooth Powder) or Lizhong Tang (Regulate the Middle Decoction), and for milder cases, Pingwei San (Calm the Stomach Powder). I find the properties of Shengjiang (Dried Ginger) and Rougui (Cinnamon Bark) too acrid and intense. Treating disease requires first considering the annual climate trends and avoiding damaging the body's natural harmony, which is crucial. Therefore, I formulated a prescription named Shengshi Hezhong Tang (Moisture-Dispersing and Middle-Harmonizing Decoction), containing Zisuye (Perilla Leaf) (use if there is aversion to cold), Banxia (Pinelliae Rhizoma), Fuling (Poria), Chenpi (Citri Reticulatae Pericarpium), and Zhigancao (Prepared Licorice Root) (these four ingredients form Erchen Tang [Two-Aged Decoction] to resolve phlegm and overcome dampness), Houpo (Magnoliae Officinalis Cortex), and Shenqu (Massa Medicata Fermentata) (to warm the middle and promote digestion). If the fingernails indeed appear grayish, then Danfuzi (Aconiti Lateralis Radix Praeparata) and Ganjiang (Zingiberis Rhizoma) can be added, each in small doses (fen).
Yang Summerheat occurs from traveling on roads or staying in simple shelters. Although the degree of labor and rest differs, the mechanism of contracting the disease is the same. Summerheat pathogen is formless and enters through the mouth and nose. It damages the Qi aspect of the body, leading to shortness of breath and a deficient pulse. Since Summerheat first affects the Heart, it causes mental restlessness, insomnia, and excessive sweating (as the Heart governs fluids). Symptoms may also include fever, weakness in the limbs, thirst for frozen beverages, and dark, turbid urine. Even if all six pulses are deficient and fine, the general treatment principle should be to clear Summerheat and promote diuresis to remove dampness. Drugs such as Huashi (Talcum), Danyezhu ye (Lophatheri Herba), Huangqin (Scutellariae Radix), Lianqiao (forbidden context? No, Lian is Coptidis Rhizoma/Lian), Fuling (Poria), and Yiyiren (Coicis Semen) can be selected. These should be supplemented with Qi-tonifying agents. Formulas such as Renshen Baihu Tang (Ginseng White Tiger Decoction) and Qingshu Yiqi Tang (Clear Summerheat and Boost Qi Decoction) can all be consulted for use.
A neighbor's son, aged thirteen or fourteen, had a pale complexion and a weak constitution. At that time, it was the Dog Days of summer. He went out to attend an external school. Under the blazing midday sun, many people drank well water. The neighbor's son also drank two cups, after which he could no longer go to school. His eyes were wide open, his spirit dull, and he lay listlessly on his bed. His father and elder brothers invited someone to prick the Shaoshang (LU11) acupoint, releasing a small amount of purple blood, followed by the administration of Shaya medicines (plague/summerheat antidotes). By the hour of Xu (7-9 PM), they invited me to examine him. His six pulses were imperceptible, and his fingernails were entirely gray. I said, "This is a case of Cold contracted during the Dog Days, known as Yin Summerheat. If he had taken Fuzi Lizhong Tang (Aconite Regulate the Middle Decoction), he might have been saved, but now it is too late." He passed away after noon.
Another person returned home after traveling, suffering from abdominal pain, wanting to vomit but unable to do so, and wanting to defecate but unable to do so. This is Dry Huoluan (Stomach Intestine Turmoil), also known as Jiaochang Sha (Intestine-Twisting Plague). It is appropriate to use fried salt dissolved in hot water, drink it when warm, and induce vomiting by stimulating the throat. Alternatively, one can use a porcelain plate dipped in sesame oil to scrape the chest and back extensively until the Qi of the internal organs flows freely, allowing for vomiting and defecation, which would render the condition harmless. This person did not know the treatment method and consumed a bowl of old ginger soup, resulting in death. This falls under the category of Yang Summerheat.
