张思顺盛夏调官都城苦热食冰雪过多又饮木瓜浆积冷于中遂感脾疼之疾药不释口殊无退

岁日斋一道人适一道人曰我受官人供固非所惜但取汉椒二十一粒浸于浆水碗中一宿漉出还以
浆水吞之若是而已张如所戒明日椒才下腹即脱然更不复作(类编)
有一位患者，每天早晨起床后必须大便一次，有时腹痛，有时不痛。空腹服用热性药物也无效。后来有智者观察病情，让他晚饭前再进服一次热性药物，症状便安定下来。如此长期服用，最终安然无恙。这是因为温补性质的药物虽然清晨空腹时服用，但到了晚上药效已经消散，夜晚的阴寒之气无法抵御。如果在晚间再次进服热性药物，那么整夜都有温药在腹中，从而能够胜过阴寒之气。凡是治疗寒性疾病，都是这个道理。
第一种是伤暑引起的腹泻；第二种是受冷物、食物、瓜果、饮水等引起的腹泻；第三种是夏季心火旺盛，心经有热导致小便不利，进而影响大肠，称为“水谷不分”。因伤暑而腹泻的，伴有心烦急躁、头痛、口渴，适宜服用香薷饮、乌金散。因受冷物而腹泻的，伴有腹痛、水样泻、食物不消化，适宜服用附子、理中丸、二气丹、正丸、丹紫苏丸等温性药物。因水谷不分而腹泻的，适宜服用大顺散、五苓散。这两种药专门用于分清别浊。暑天多患此病，所以人们常用这些药。凡是腹泻，不可急于用热性药物止泻，恐怕会转变成痢疾。（同上）
治疗胃气引起的小腹剧烈疼痛。元丰年间，丞相王郇公小腹疼痛不止，朝廷派遣太医全力诊治，均无效果。凡是用到热性如附子、硫黄、五夜义丸之类的药物，使用也不见好转。驸马张都尉让人取妇女头发烧成灰，细细研磨过筛，用温酒调服二钱，疼痛立刻停止。（《良方》）
头部和心脏的疾病，有厥痛和真痛之分。手三阳经脉受风寒侵袭，名为厥头痛；疼痛深入连及脑部，名为真头痛。五脏之气相互干扰，名为厥心痛；如果疼痛非常剧烈，且仅在心部，手足发青，名为真心痛。真心痛的患者，早上发病晚上死亡，晚上发病早上死亡。
张思顺在盛夏时节调任都城，因酷热食用过多冰雪，又饮用木瓜浆，导致寒气积聚于体内，于是患上脾疼之症。服药不断，却毫无退症迹象。多年后，日斋一道人恰好遇到另一位道人，说道：“我接受您的供养固然不惜惜，只需取汉椒二十一粒，浸泡在浆水碗中一夜，滤出花椒，再用浆水吞服即可，仅此而已。”张思顺依从告诫，第二天花椒刚下肚，病痛立即消除，从此不再复发。（《类编》）
A patient experienced a bowel movement every morning upon rising, with occasional abdominal pain or no pain at all. Taking hot-natured medicines on an empty stomach proved ineffective. Later, a wise observer noted this and instructed the patient to take another dose of hot-natured medicine before the evening meal, after which the condition stabilized. By continuing this regimen long-term, the patient remained healthy. This is because although warming medicines taken on an empty stomach in the early morning have dissipated by evening, leaving the body unable to resist the yin-cold qi of the night. Administering hot-natured medicine again in the evening ensures that warming agents remain in the abdomen throughout the night, thereby overcoming the yin-cold qi. This principle applies to the treatment of all cold diseases.
There are three types: first, diarrhea caused by summerheat injury; second, diarrhea caused by cold substances, food, melons, fruits, and drinking water; third, excessive heart fire in summer leading to heat in the Heart meridian, causing difficult urination, which then affects the Large Intestine, termed "failure to separate clear from turbid" (Shuigu Bufen). For diarrhea due to summerheat injury, accompanied by mental restlessness, headache, and thirst, Xiangru Yin (Elsholtzia Decoction) and Wujin San (Black Gold Powder) are suitable. For diarrhea due to cold substances, accompanied by abdominal pain, watery stool, and undigested food, warming medicines such as Fuzi (Prepared Aconite Root), Lizhong Wan (Regulate the Middle Pill), Erqi Dan (Two Qi Pill), Zhengwan, and Danzisuan Wan (Red Perilla Pill) are appropriate. For failure to separate clear from turbid, Dashun San (Great Harmony Powder) and Wuling San (Five Ling Powder) are indicated. These two medicines specialize in separating clear from turbid. This disease is common in summer months, hence people often use these remedies. In cases of diarrhea, one must not hastily stop it with hot-natured medicines, lest it transform into dysentery (Li Ji).
Treatment for severe lower abdominal pain caused by Stomach qi disharmony. During the Yuanfeng era, Chancellor Wang Xungong suffered from incessant lower abdominal pain. Imperial physicians were dispatched to treat him thoroughly, but all efforts failed. Even hot-natured medicines like Fuzi (Prepared Aconite Root), Liuhuang (Sulfur), and Wuye Yi Wan (Five Nights One Pill) yielded no improvement. The Prince Consort Zhang Duwei ordered women's hair to be burned to ash, finely ground and sifted, then mixed with warm wine and administered (2 qian). The pain ceased immediately (Liang Fang).
Diseases of the head and heart include Jue Tong (Rebellious Pain) and Zhen Tong (True Pain). When the Hand-Taiyang meridians are invaded by wind-cold, it is named Jue Tou Tong (Rebellious Headache); if the pain penetrates deeply into the brain, it is named Zhen Tou Tong (True Headache). When qi from the Five Viscera interferes with each other, it is named Jue Xin Tong (Rebellious Heartache); if the pain is severe, localized solely in the heart region, and accompanied by cyanosis of the hands and feet, it is named Zhen Xin Tong (True Heartache). Patients with True Heartache who manifest symptoms in the morning will die by evening, and those who manifest symptoms in the evening will die by morning.
Zhang Shishun was transferred to the capital during midsummer. Suffering from intense heat, he consumed excessive ice and snow and drank papaya juice, causing cold accumulation in the interior. Consequently, he contracted Pi Teng (Spleen Pain). Medicines were taken continuously without any alleviation. Years later, Daoist Renzhai encountered another Daoist, who said, "I do not begrudge your offerings. Simply take twenty-one grains of Hanjiao (Sichuan Pepper), soak them in Jiangshui (fermented grain water) overnight, strain them out, and swallow them with the Jiangshui. That is all." Zhang followed the advice. The next day, as soon as the pepper entered his abdomen, the pain vanished completely, and it never recurred (Leibian).
