When a young child first presents with fever and before the smallpox/rash lesions have erupted, one should pre-emptively dip hands in sesame oil (Sesami Oleum), rub until warm, and then press and massage the child's back several times. This can prevent eruption in mild cases, and even if eruption occurs in severe cases, it will be sparse. This is also an ancient massage method, likely intended to disperse cold pathogens and prevent the counterflow of water-toxin. The back is the pathway of the Foot-Taiyang Bladder Channel (Zú Tàiyáng Pángguāng Jīng). This aligns with Li Dongyuan's theories. Caution must be exercised; if performed by women, excessive force might injure the delicate skin of the infant.

In another case, a child suffered from convulsive wind (Jing Feng) with spasms and eyes rolling upward. When medicine was brought to the mouth, it was vomited out. I therefore took Bamboo Shavings (Zhuru) and Rush Pith (Dengxin), crushed them into coarse powder, added a little fresh Ginger Juice (Shengjiang Zhi), mixed it evenly with Sesame Oil, and massaged the child from the forehead down to the center of the back, as well as the palms of both hands and soles of both feet, for dozens of repetitions. Subsequently, I decocted Mint (Bohe) in water and slowly administered it to the child. After some time, the convulsions subsided, the fever receded, and the child recovered.

In the book *Danxi Yao An* or *Wen*, compiled by his disciple Zhao Liangren, I observed that in the section on "Fever," Chicken Square Fruit (Jimuzi) is used to treat fever in individuals suffering from alcohol intoxication. Initially, I did not understand what this substance was. *Su Shen Liang Fang* states that "Chicken Square Fruit" is commonly called "Leprous Man's Finger," and its taste resembles milk, yet this explanation remains unclear. Later, reading the *Wulei Xianggan Zhi* by Monk Zan Ning, I found that Zhiju (Acanthopanax sessiliflorus fruit) is also known as Zhiguozi, erroneously referred to in folklore as Jimuzi, and also called Mumì. It has a sweet and neutral flavor, is non-toxic, and the tree resembles a white poplar. Its fruits grow at the branch tips, are several inches long like a little finger, curved and connected, and taste sweet like maltose when eaten, ripening in the eighth and ninth lunar months. Using wood from this tree as house pillars causes the wine stored in the room to become bland. It is a sacred remedy for resolving alcohol toxicity and treating Xiao Ke (wasting-thirst syndrome). Ancient single-formula prescriptions for treating Jiuzhi (alcohol accumulation) were very effective. In Jiangnan, it is called Baishi Shu. The line in the *Classic of Poetry*, "There are jujubes on the southern mountain," refers to this.

Regarding Pengli (Rubus chingii): Old annotations in the Materia Medica stated that Fupenzi (Rubus chingii fruit) and Pengli were the same plant with different names. Modern annotations claim that Pengli is the seedling of Fupenzi, and Fupenzi is the fruit of Pengli, which is entirely incorrect. *Yanyi* further describes it as soft, red, and lovely, thereby confusing Pengli with Fupenzi. According to Zhang Shilang's *Nanyuan Manlu* from Yunnan: Pengli is initially light red and turns deep purple when ripe; its taste is sweet, sour, and bland. It has prickles, grows as a vine with long stems, and possesses large, sparse thorns; even when withered, the branches remain intact. Fupenzi is initially yellow and turns red when ripe; its taste is sweet and deeply sour. It has prickles, grows on trees that are not very tall, and possesses fine, dense thorns; its leaves and branches remain green throughout the four seasons. Mr. Zhang, a man of broad learning, corrected the errors of the old Materia Medica annotations based on his observations, achieving great merit. As the ancients said, "Misannotating the Materia Medica is no trivial matter." I have detailed this specifically.
