天津徐姓媪，年近五旬，于季夏得疟疾。
病因 勤俭持家，中馈事多躬操，且宅旁设有面粉庄，其饭亦由家出，劳而兼暑，遂至病疟。
证候 其病间日一发，先冷后热，其冷甚轻，其热甚剧。恶心懒食，心中时常发热，思
食凉物。其脉左部弦硬，右部洪实。大便干燥，小便赤涩，屡次服药无效。
诊断 此乃肝胆伏有疟邪，胃腑郁有暑热，暑热疟邪相并而为寒热往来，然寒少热多，此方书
所谓阳明热疟也。宜祛其肝胆之邪，兼清其胃腑之热。
处方 生石膏（一两研细）
均分作三包，其未发疟之日，头午用柴胡二钱煎汤送服一包，隔半日许再用开水送服一包，至次
日前发疟五小时，再用生姜三钱煎汤送服一包。
效果 将药按期服完后，疟疾即愈，心中发热、懒食亦愈。盖石膏善清胃热，兼能清肝胆之
热，初次用柴胡煎汤送服者，所以和解少阳之邪也。至三次用生姜煎汤送服者，是防其疟疾
将发与太阳相并而生寒也。
天津刘××，年三十二岁，于季秋患疟又兼下痢。
病因 因需车孔亟，机轮坏处，须得急速收拾，忙时恒彻夜不眠，劳苦过甚，遂至下痢，继又病疟。
证候 其痢赤白参半，一昼夜十余次，下坠腹疼，其疟间日一发，寒轻热重，其脉左右皆有弦
象，而左关独弦而有力。
诊断 此证之脉，左右皆弦者，病疟之脉，大抵如此。其左关独弦而有力者，其病根在肝胆也。
为肝胆有外受之邪是以脉现弦象，而病疟为其所受之邪为外感之热邪，是以左关脉象弦
而有力，其热下迫肠中而下痢。拟清肝胆之热，散其外感之邪，则疟痢庶可同愈。
处方 生杭芍（一两） 山楂片（三钱） 茵陈（二钱） 生麦芽（二钱）
柴胡（钱半） 常山（钱半酒炒） 草果（钱半捣碎） 黄芩（钱半） 甘草（二钱） 生姜（三片）
煎汤一大盅，于不发疟之日晚间服之，翌晨煎渣再服一次。
效果 将药如法服后，疟痢皆愈。又为开生怀山药一两，生杭芍三钱，黄色生鸡内金一钱，俾日
煎服一剂，以滋阴、培气、化瘀，连服数日以善其后。
An elderly woman surnamed Xu in Tianjin, nearing fifty years of age, contracted malaria (Malaria) in late summer.
Etiology: She managed the household frugally and diligently, performing many domestic chores personally. Additionally, a flour mill was located beside her residence, and the family's meals were supplied from there. Due to labor combined with exposure to summer-heat (Summer-heat), she developed malaria.
Symptoms: The disease manifested every other day, beginning with chills followed by fever. The chills were mild, while the fever was severe. She experienced nausea, anorexia (loss of appetite), frequent sensations of heat in the heart region, and a craving for cold foods. Her pulse was wiry and hard on the left side, and surging and full on the right side. Her stool was dry, and her urine was scanty, red, and painful. Multiple courses of medication proved ineffective.
Diagnosis: This condition involves latent malarial pathogens (Malarial pathogen) in the Liver and Gallbladder, and stagnant summer-heat (Summer-heat) in the Stomach. The combination of summer-heat and malarial pathogens results in alternating chills and fever. However, since the chills are few and the fever is abundant, this corresponds to what medical texts describe as "Yangming Heat Malaria" (Heat-type Malaria involving the Yangming channel). It is appropriate to expel the pathogens from the Liver and Gallbladder while simultaneously clearing the heat from the Stomach.
Prescription: Raw Gypsum (Shi Gao, 30g, finely ground)
Divided equally into three packets. On days when malaria does not attack, take one packet with decoction of Bupleurum Radix (Chai Hu, 6g) in the morning; half a day later, take another packet with plain boiled water; five hours before the expected onset of malaria on the following day, take the final packet with decoction of Fresh Ginger (Sheng Jiang, 9g).
Outcome: After completing the scheduled dosage, the malaria was cured, and the sensations of heat in the heart region and anorexia also resolved. Gypsum excels at clearing Stomach heat and can also clear Liver and Gallbladder heat. The initial administration with Bupleurum Radix decoction was intended to harmonize the Shaoyang (Lesser Yang) channel and resolve its pathogens. The subsequent administration with Fresh Ginger decoction was to prevent the impending malaria from combining with the Taiyang (Greater Yang) channel, which would generate chills.
Mr. Liu XX from Tianjin, aged thirty-two, contracted malaria accompanied by dysentery in late autumn.
Etiology: Urgently needing a cart, he had to rush repairs to a broken wheel, often staying awake all night during busy periods. Excessive fatigue and hardship led to dysentery, followed by malaria.
Symptoms: His dysentery consisted of mixed red and white pus and blood, occurring more than ten times per day, accompanied by a sensation of rectal tenesmus (bearing down) and abdominal pain. His malaria occurred every other day, with mild chills and heavy fever. His pulse showed a wiry quality in both left and right positions, but the left Guan position was distinctly wiry and forceful.
Diagnosis: A wiry pulse in both left and right positions is typical for malaria. The distinct wiriness and forcefulness at the left Guan position indicate that the root of the disease lies in the Liver and Gallbladder. The wiry pulse arises because the Liver and Gallbladder have been invaded by external pathogens. Since the pathogen causing the malaria is an externally contracted heat pathogen, the left Guan pulse is wiry and forceful. The heat forces downward into the intestines, resulting in dysentery. The proposed treatment is to clear the heat from the Liver and Gallbladder and disperse the externally contracted pathogens, so that both malaria and dysentery may be cured simultaneously.
Prescription: Raw Hang Peony Root (Sheng Hang Shao, 30g) Sliced Hawthorn Fruit (Shan Zha Pian, 9g) Virgate Wormwood Herb (Yin Chen, 6g) Raw Barley Sprout (Sheng Mai Ya, 6g)
Bupleurum Radix (Chai Hu, 4.5g) Rhizoma Dichroae (Chang Shan, 4.5g, wine-fried) Rhizoma Tsaoko (Cao Guo, 4.5g, crushed) Scutellaria Root (Huang Qin, 4.5g) Licorice Root (Gan Cao, 6g) Fresh Ginger (Sheng Jiang, 3 slices)
Decoct in a large bowl of water. Take the decoction in the evening on non-malaria days, and re-decoct the dregs the next morning for a second dose.
Outcome: Following the prescribed method, both malaria and dysentery were cured. Subsequently, a prescription was provided containing Raw Huai Yam (Sheng Huai Shan Yao, 30g), Raw Hang Peony Root (Sheng Hang Shao, 9g), and Yellow Raw Chicken Gizzard Lining (Huang Se Sheng Ji Nei Jin, 3g), to be decocted and taken as one dose daily. This regimen nourishes Yin, tonifies Qi, and resolves stasis, administered continuously for several days to consolidate recovery.
