Lu Rong, a Censor-in-Chief (Can Zheng), once heard at a banquet that a physician claimed wine should not be consumed when frozen. Lu was quite surprised, thinking the doctor merely misunderstood Zhu Danxi's theories.

A few years later, in autumn, Lu contracted dysentery and invited this physician to treat him. The physician asked, "Did you perhaps drink excessive amounts of cold wine?" Lu admitted this truthfully, confessing that he had always followed Zhu Danxi's advice to drink chilled pure wine during the summer heat.

The physician replied, "Zhu Danxi only knew the harm of hot wine but did not know that the harm of cold wine is even more severe." After taking several doses of medicine, the illness ceased.

I read in *Ru Men Shi Qin* (Records of Confucian Medicine) that Zhang Da-ren treated a patient who was critically ill with high fever. When Zhang visited, the patient said, "I have no other ailments. Three years ago, during the peak of summer heat, while out in the countryside, someone offered me boiled wine. Since there were no vessels available to warm it, I drank several sheng [a unit of volume] after cooling it by freezing. I immediately felt stuffiness in my left hypochondrium, which gradually became painful, forming a hard mass like stone that has not dissolved since. Acupuncture and powdered medicines yielded no effect."

Zhang examined the pulses of both hands, finding them deep, solid, and forceful. He first administered Du Sheng San (Single Holy Powder) to induce vomiting. Upon vomiting two or three sheng of material smelling like wine, the pain stopped immediately. Later, he prescribed formulas to harmonize the Spleen and Stomach, leading to recovery. This revealed how severely cold wine could cause disease.

Wang Yishan, over sixty years old, suffered from accumulated toxins in the Zang organs due to excessive consumption of crabs. In autumn, he developed dysentery with pus and blood in the stool, occurring thirty to forty times a day. Physicians typically used hemostatic agents without success. After half a year, his Qi and Blood gradually weakened, food intake decreased, and muscles wasted away. Taking warming herbs aggravated abdominal pain and bleeding; taking cooling herbs caused watery diarrhea. All physicians were at their wit's end, helpless and awaiting death.

His relatives invited me to treat him. I prescribed one liang of Ren Shen (Ginseng Radix), five qian of Chun Bai Pi (Celastrus Cortex), and 1.5 qian of Gan Cao (Licorice Root). After one dose, symptoms halved; after two doses, improvement was gradual; after three doses, pus and blood stopped abruptly, and normal feces appeared.

After half a month of conditioning, his complexion became plump and lustrous, spirit doubled, diet returned to normal, and pulses became peaceful.

Malaria (Nue) is a disease characterized by alternating chills and fever. Occurring every two days is termed Jian Ri Nue (Intermittent Malaria); persisting for years is termed Lao Nue (Chronic/Consumptive Malaria). The Q&A in *Huang Di Nei Jing* (Yellow Emperor's Inner Canon) is exhaustive. However, modern practitioners rarely study it deeply. Instead, they propagate the theory that "no phlegm, no malaria," using arsenic (Pi Shi) and soybean flour pills coated with Cinnabar (Zhu Sha), called "Malaria Pills" (Nue Dan); or using Hedyotis Diffusa (Chang Shan) as the chief ingredient, called "Malaria Medicine" (Nue Yao). They treat all cases indiscriminately regardless of deficiency or excess.

Sometimes, these treatments coincidentally match Phlegm-type Malaria and yield temporary effects. However, for patients with Spleen Qi deficiency and weakness, whose malaria is not caused by phlegm but by Seven Emotions (Qi Qing), administering these drugs causes severe vomiting, reversing the flow of Essence source and Marrow Sea, aggravating the disease condition, causing significant harm. Women fear vomiting especially, making immediate administration difficult. One must carefully investigate the disease origin, distinguishing between Summerheat Malaria, Wind Malaria, Dampness Malaria, Phlegm Malaria, Food Malaria, and Chronic Malaria.

For poor and low-status individuals, although their bodies suffer hardship, their minds are tranquil. Even if toxic drugs like Arsenic and Cinnabar are used to attack heat with heat, efficacy can be achieved. Conversely, wealthy and noble individuals often exert their minds excessively and enjoy rich nourishment, causing internal fire and external fire to activate simultaneously. Attacking heat with heat may transform into hematemesis, bloody diarrhea, sores, ulcers, and vomiting. How can such cases be treated uniformly?
