天津李姓媪，年过六旬，于仲夏得霍乱证。
病因 天气炎热，有事出门，道途受暑，归家又复自炊，多受炭气，遂病霍乱。
证候 恶心呕吐，腹疼泄泻，得病不过十小时，吐泻已十余次
矣。其手足皆凉，手凉至肘，足凉至膝，心中则觉发热，其脉沉细欲无，不足四至。
诊断 此霍乱之毒菌随溽暑之热传入脏腑也。其心脏受毒菌之麻痹，跳动之机关将停，是
以脉沉细且迟；其血脉之流通无力，不能达于四肢，是以手足皆凉；其毒菌侵入肠胃，俾肠
胃之气化失和，兼以脏腑之正气与侵入之邪气，互相格拒，是以恶心腹疼，吐泻交作；其
心中发热者固系夹杂暑气，而霍乱之属阳者，即不夹杂暑气，亦恒令人心中发热也。此宜
治以解毒清热之剂。
处方 卫生防疫宝丹（百六十粒） 离中丹（四钱） 益元散（四钱）
先将卫生防疫宝丹分三次用开水送服，约半点多钟服一次，服完三次，其恶心腹疼当愈，呕
吐泄泻亦当随愈。愈后若仍觉心中热者，再将后二味药和匀，亦分三次用开水送服。每
一点钟服一次，热退者不必尽服。
效果 将卫生防疫宝丹分三次服完，果恶心、呕吐、腹疼、泄泻皆愈。而心中之热，未见轻减，
继将离中丹、益元散和匀，分三次服完，其热遂消，病全愈。
天津一位李姓老妇人，年龄超过六十岁，在仲夏时节患上了霍乱证。
病因：天气炎热，她有事出门，在路上受到暑邪侵袭，回家后又自己生火做饭，吸入过多的炭气，于是患上了霍乱。
证候：恶心呕吐，腹痛腹泻，患病不过十个小时，呕吐和腹泻已经发生了十多次。她的四肢发凉，手凉到了肘部，脚凉到了膝盖，心中却感觉发热，脉象沉细几乎摸不到，每息不足四次跳动。
诊断：这是霍乱的毒菌随着潮湿暑热传入脏腑所致。心脏受到毒菌麻痹，跳动的机能即将停止，所以脉象沉细且迟缓；血脉流通无力，不能到达四肢，所以手足都发凉；毒菌侵入肠胃，使得肠胃的气化功能失调，加上脏腑的正气与侵入的邪气互相排斥抗拒，所以出现恶心、腹痛，呕吐和腹泻交替发作；心中发热固然夹杂了暑气，但属于阳证的霍乱，即使不夹杂暑气，也常常让人心中发热。这种情况适宜用解毒清热的方剂来治疗。
处方：卫生防疫宝丹（一百六十粒）、离中丹（四钱）、益元散（四钱）。
先将卫生防疫宝丹分三次用开水送服，大约半个多小时服用一次，服完三次后，恶心和腹痛应当痊愈，呕吐和腹泻也会随之痊愈。病愈后如果仍然觉得心中发热，再将后面两种药混合均匀，也分三次用开水送服。每小时服用一次，热退后不必全部服完。
效果：将卫生防疫宝丹分三次服完后，果然恶心、呕吐、腹痛、腹泻都痊愈了。但是心中的热感没有减轻，接着将离中丹和益元散混合均匀，分三次服完，热感随即消除，疾病完全痊愈。
An elderly surnamed Li from Tianjin, over sixty years of age, contracted Huoluan (cholera-like syndrome) in midsummer.
Etiology: Due to the hot weather, she went out for some business and was exposed to summer-heat on the road. Upon returning home, she cooked herself, inhaling excessive charcoal smoke, which led to the onset of Huoluan.
Symptoms: Nausea, vomiting, abdominal pain, and diarrhea. Within ten hours of onset, vomiting and diarrhea occurred more than ten times. Her hands and feet were cold; hand coldness extended to the elbows, and foot coldness extended to the knees. She felt heat in the heart region. Her pulse was deep, fine, and nearly imperceptible, with fewer than four beats per respiration.
Diagnosis: This is caused by Huoluan pathogens entering the Zang-Fu organs along with damp-summer-heat. The heart is paralyzed by the pathogens, causing the mechanism of heartbeat to nearly cease, resulting in a deep, fine, and slow pulse. The blood vessels lack the strength to circulate effectively to the limbs, causing coldness in the hands and feet. The pathogens invade the intestines and stomach, disrupting their Qi transformation functions. Additionally, the healthy Qi of the Zang-Fu organs repels the invading pathogenic Qi, leading to nausea, abdominal pain, and alternating vomiting and diarrhea. The sensation of heat in the heart region is indeed due to the presence of summer-heat; however, even in Yang-type Huoluan without summer-heat, heat in the heart region is common. Treatment should employ formulas that detoxify and clear heat.
Prescription: Weisheng Fangyi Baodan (160 pills), Lizhong Dan (4 qian), Yiyuan San (4 qian).
First, administer Weisheng Fangyi Baodan in three doses, taken with warm water, approximately every half hour. After completing the three doses, the nausea and abdominal pain should resolve, and vomiting and diarrhea will likely subside accordingly. If heat in the heart region persists after recovery, mix the latter two medicines evenly and also divide them into three doses to be taken with warm water. Take once every hour; if the heat subsides, there is no need to finish the remaining doses.
Outcome: After taking Weisheng Fangyi Baodan in three doses, the nausea, vomiting, abdominal pain, and diarrhea all resolved. However, the heat in the heart region did not diminish. Subsequently, Lizhong Dan and Yiyuan San were mixed evenly and taken in three doses. The heat then disappeared, and the patient made a full recovery.
