治温病初得，其脉浮而有力，身体壮热。并治一切感冒初得，身不恶寒而心中发热者。若其热已入阳明
之腑，亦可用代白虎汤。
生石膏（二两，轧细） 生粳米（二两半）
上二味，用水三大碗，煎至米烂熟，约可得清汁两大腕。乘热尽量饮之，使周身皆汗出，病无不愈者。
若阳明腑热已实，不必乘热顿饮之，徐徐温饮下，以消其热可也。
或问∶外感初得，即中有蕴热，阳明胃腑，不至燥实，何至速用生石膏二两？答曰∶此方妙在将石膏同
粳米煎汤，乘热饮之。俾石膏寒凉之性，随热汤发散之力，化为汗液尽达于外也。西人谓，胃本无化水之能，
亦无出水之路。而壮实之人，饮水满胃，须臾水气旁达，胃中即空。盖胃中原多微丝血管，能引水气以入回血

胃中，又善留蓄热力，以为作汗之助也。是以人之欲发汗者，饮热茶不如啜热粥也。
初拟此方时，惟用以治温病。实验既久，知伤寒两三日后，身不恶寒而发热者，用之亦效。丙辰正月上旬，

灌下。病患霍然顿醒。其家人惊喜异常，直以为死后重生矣。继而热疟流行，经仆重用生石膏治愈者不胜计。
治疗温病初起，脉象浮而有力，身体高热。同时也治疗一切感冒初起，身体不怕冷但心中发热者。如果热邪已经传入阳明腑证，也可以使用代白虎汤。
以上两味药，用水三大碗，煎煮至米粒烂熟，大约可得到澄清的药汁两大碗。趁热尽量饮用，使全身出汗，病没有不愈的。
如果阳明腑热已经结实，不必趁热一次性喝完，可以慢慢温热服用，以消除热邪即可。
有人问：外感初起，体内已有蕴藏的热邪，阳明胃腑并未达到燥结实证的程度，为何要迅速使用二两生石膏？回答说：此方的妙处在于将石膏与粳米一起煎汤，趁热饮用。使得石膏寒凉的性质，随着热汤发散的力量，转化为汗液完全达于体表。西方人认为，胃本身没有化水的功能，也没有出水的路径。但是身体壮实的人，饮水充满胃部，片刻之间水气向周围渗透，胃中随即变空。大概是因为胃中原有许多微细血管，能引导水气进入回流血管，由回流血管经过肝脏进入心脏，从而在周身运行，由肺升出成为气，由皮肤渗出成为汗，其余部分透过肾脏到达膀胱成为尿液。石膏煎成的汤，没有任何气味，也没有浓稠的汁浆，简直与清水无异，而且又是趁热饮用，那么敷布的速度更快，不需要等到其寒性发作，就被胃中的微细血管吸收，转化为汗、为气，其余部分成为尿液，这样表里之热，也随之全部化解。这是“寒因热用”，不损伤胃气的治疗方法。并且与粳米同煮，其中冲和之气，能帮助胃气的发达，那么发汗自然容易。其稠润的汁液，又能滞留石膏，不让它从胃向下走，导致寒凉伤害下焦。不仅如此，清水煎开后，冷却速度很快，因为其中没有汁浆，不能留住热量。此方粳米多达二两半，汤成之后，必然汁浆非常稠厚。饮入胃中，又善于留存热力，作为作汗的辅助。所以人想要发汗时，喝热茶不如喝热粥好。
最初拟定此方时，只用来治疗温病。经过长期实验，知道伤寒两三天后，身体不怕冷而发热者，使用它也有效。丙辰年正月初旬，我从广州搬家到德州。从邯郸上火车，从南向北，又从北向南，一昼夜绕行一千多里。车窗大多破损，风寒刺骨。到了德州，同行的五六个人，都身体发热无汗。于是我用生石膏、粳米各十余两，在饭甑中蒸烂熟，让病人尽量饮用热汤，都全身出汗而痊愈，当时大家感到非常痛快。
沈阳朱姓妇女，五十岁。在戊午年深秋，得了严重的温病。当时我刚到奉天，请求我为她看病。见她用冰袋当枕头，又悬挂冰袋贴在面部侧面。这是因为之前请日本人治疗，是那种治疗方法。她闭着眼睛昏昏沉沉像睡着一样，大声呼喊，毫无知觉。她的脉象洪大无比，按下去非常坚实。我对她的丈夫说：这个病是阳明腑热，已经到了极点。外用冰块，会使热邪更加内陷。但是这个病还可以治，非重用生石膏不可。她的丈夫赞同我的话，于是用生石膏细末四两、粳米八钱，煎取澄清药汁四茶杯，慢慢温热灌服。大约过了十个小时，将药服完，突然清醒过来。后来又用知母、花粉、玄参、白芍等药，少加连翘以清除余热，服用两剂后完全痊愈。

江苏崇明县蔡××来信：
深秋时节，我处的张氏女儿得了严重的瘟病，服药无效，医生说治不好，病家认为没有希望。她的母亲求人来请我去诊治，见到她神志昏迷像睡着一样，高声呼喊也不觉得；脉象非常洪大坚实。使用先生所拟定的石膏粳米汤，生石膏用三两，粳米用五钱。看到的人无不惊讶嘲笑。而且有一位老医生对人扬言说：“蔡某年仅二十岁，看书不过一年多，竟然大胆到这种程度！石膏重用三两，即使是煅用的也不可，何况是生的呢？这药咽下去，人就会死。”有人听到这话，急忙来告诉我，我说：“此方如果用煅石膏，不需要三两，就是一两也足以断送人命还有余。如果是用生的，即使再多几两也没关系，何况只有三两呢。”于是急忙催促病家买药，亲自监督，煎取澄清药汤一大碗，慢慢温热灌服。病患突然清醒过来。他的家人惊喜异常，简直以为是死后重生。接着热疟流行，经我重用生石膏治愈的人不计其数。
Treats the initial stage of warm diseases (Wen Bing, febrile diseases caused by warm pathogens), characterized by a floating and forceful pulse, and high body heat. It also treats all types of common colds in their initial stage where there is no aversion to cold but a sensation of heat in the heart/mind. If the heat has entered the Yangming Fu-organ syndrome, Dai Baihu Tang can also be used.
Raw Gypsum Fibrosum (Shi Gao) [two taels, finely crushed] Raw Oryza Sativa Grain (Jing Mi) [two taels and a half]
Take the above two ingredients, add three large bowls of water, and decoct until the rice grains are soft and cooked. Approximately two large bowls of clear liquid can be obtained. Drink it as much as possible while hot, inducing sweating throughout the body; the disease will invariably be cured.
If the Yangming Fu-organ heat is already solidified/excessive, there is no need to drink it all at once while hot; it can be taken slowly in warm doses to dissipate the heat.
A question arises: In the initial stage of external contraction, if there is already latent heat inside, and the Yangming Stomach organ has not reached a state of dryness and excess, why use two taels of Raw Gypsum Fibrosum so quickly? The answer is: The brilliance of this formula lies in decocting Gypsum Fibrosum together with Oryza Sativa Grain and drinking it while hot. This allows the cooling nature of Gypsum Fibrosum to be transformed into sweat and reach the exterior through the dispersing power of the hot decoction. Western medicine posits that the stomach lacks the ability to transform water and has no outlet for water discharge. However, in robust individuals, when the stomach is filled with water, within moments the water vapor spreads laterally, leaving the stomach empty. This is likely because the stomach contains numerous capillaries that can draw water vapor into the venous return vessels. From there, it passes through the liver to the heart, circulating throughout the body. It rises via the lungs to become Qi, exudes through the skin as sweat, and the remainder penetrates the kidneys to the bladder to become urine. The decoction of Gypsum Fibrosum has no odor and no viscous consistency, being virtually identical to clear water. Moreover, since it is drunk hot, its distribution is even faster. Before its cooling properties can take effect, it is absorbed by the gastric capillaries, transforming into sweat, Qi, and the remainder becomes urine. Thus, the heat in both the interior and exterior is simultaneously resolved. This method utilizes cold herbs with heat ("Han Yin Re Yong"), avoiding damage to the stomach. Furthermore, boiling it with Oryza Sativa Grain provides a harmonious Qi that assists the development of Stomach Qi, making sweating easier. Its viscous juice retains the Gypsum Fibrosum, preventing it from descending rapidly through the stomach, which would otherwise cause the cold nature to harm the Lower Jiao. Additionally, clear water cools down very quickly after boiling because it lacks viscous components to retain heat. This formula uses a large amount of Oryza Sativa Grain (two taels and a half); upon completion, the decoction must be quite viscous. Once ingested into the stomach, it effectively retains heat energy, assisting in the generation of sweat. Therefore, for those wishing to induce sweating, drinking hot tea is inferior to sipping hot congee.
Initially, I formulated this prescription solely for treating warm diseases. After long-term clinical practice, I found it effective for Taiyang cold damage (Shang Han) presenting with fever without aversion to cold after two or three days. In early January of the Bingchen year, I moved my residence from Guangzhou to Dezhou. Traveling by train from Handan, going south then north, and back again, covering over a thousand li in twenty-four hours. Many window panes were broken, allowing bone-chilling wind and cold to penetrate. Upon arriving in Dezhou, five or six companions suffered from fever and lack of sweat. I therefore used over ten taels each of Raw Gypsum Fibrosum and Oryza Sativa Grain, steamed them thoroughly in a rice steamer, and allowed the patients to drink the hot decoction to satiety. All recovered with full-body sweating, bringing great relief to everyone at the time.
A female patient surnamed Zhu from Shenyang, aged fifty, suffered from severe warm disease in late autumn of the Wuwu year. I had just arrived in Fengtian when she sought my medical attention. She was using an ice bag as a pillow and had another ice bag suspended against the side of her face. This was a treatment method previously employed by Japanese doctors. Her eyes were closed, appearing drowsy; she was unresponsive even to loud calls. Her pulse was extremely surging and forceful, feeling very solid upon pressure. I told her husband: "This condition involves extreme heat in the Yangming Fu-organ. External application of ice causes the heat to sink deeper inward. However, this case is still treatable, and it requires a heavy dose of Raw Gypsum Fibrosum." Her husband agreed with my assessment. I prescribed four taels of fine powder of Raw Gypsum Fibrosum and eight qian of Oryza Sativa Grain, decocted to yield four teacups of clear liquid, which was administered slowly in warm doses. After approximately ten hours, the medication was fully consumed, and she suddenly regained consciousness. Subsequently, I used Anemarrhenae Rhizoma (Zhi Mu), Trichosanthis Radix (Gua Lou Gen), Scrophulariae Radix (Xuan Shen), and Paeoniae Radix Alba (Bai Shao), adding a small amount of Forsythiae Fructum (Lian Qiao) to clear residual heat. After two doses, she made a complete recovery.
Appendix:
Letter from Cai XX of Chongming County, Jiangsu Province:
In late autumn, the daughter of the Zhang family in my area contracted a severe pestilential disease. Medication proved ineffective, and physicians declared it incurable, leading the family to despair. Her mother requested my services. Upon examination, I found her spirit confused as if asleep, unresponsive to loud calls; her pulse was extremely surging and solid. I used Mr.'s proposed Shi Gao Jing Mi Tang, using three taels of Raw Gypsum Fibrosum and five qian of Oryza Sativa Grain. Those present were astonished and ridiculed. An old physician publicly declared: "Cai's daughter is only twenty years old, having studied medicine for barely a year, yet she is so bold! Using three taels of Gypsum Fibrosum is inadvisable even if calcined, let alone raw! Once this medicine is swallowed, death will ensue." Someone heard this and urgently informed me. I replied: "If calcined Gypsum Fibrosum were used, one tael would be more than enough to cause death; three taels would be excessive. But if raw Gypsum Fibrosum is used, even several additional taels would be harmless, let alone three taels." I urged the family to purchase the medicine immediately and supervised the decoction myself. One large bowl of clear decoction was prepared and administered slowly in warm doses. The patient suddenly woke up. Her family was overjoyed, believing she had been resurrected from death. Later, during an epidemic of heat-malaria, countless cases were cured by my heavy use of Raw Gypsum Fibrosum.
