*Beihu Lu* records that the jellyfish is also known as "Zha" or "Shijing." People in the south catch and eat it, believing its nature is hot and biased, capable of treating "He Yu Zhi Ji" (diseases caused by eating raw or cold fish/meat, such as abdominal pain and diarrhea). *Wulei Xianggan Zhi* records that conchs are large like beds or small like buckets; they have no intestines or stomachs, no eyes, and use shrimp eyes as their own. When the shrimp moves, the conch moves, hence called jellyfish. According to *Bencao*, jellyfish tastes salty, is non-toxic, primarily tonifies vital Qi, and treats women's consumptive diseases, blood stasis, leukorrhea, pediatric wind disorders, and erysipelas. Therefore, jellyfish should be salty and cold in nature. *Beihu Lu* states it is hot, which is an error. People in Wu call it "Haizhe."

*Shilongrui*, commonly known as Maoji Cao (Cat Track Grass), has hairy and pointed leaves. Rubbing the leaf on the arm causes blisters, a method called Tian Jiu (Sky Moxibustion), used to treat persistent malaria.

Xixian Cao, commonly called Huoxian Cao, sprouts in spring with narrow, long leaves resembling mustard greens. The stems are two to three feet high. It flowers in early autumn like chrysanthemum and bears fruit resembling *Heshi* (Datura seed) in late autumn. Leaves harvested in summer and sun-dried can be taken alone to greatly benefit Yuan Qi and effectively treat wind disorders.

In Shandong, one household shared cooking for over five hundred people for more than two hundred years without contracting plague or miasma. Every year, on the morning of the Sanfu days (the hottest period of summer), they gathered a bundle of bitter mugwort heads, dried them in the shade, and pounded them into fine powder by Winter Solstice. On New Year's Eve, they mixed the powder with honey. From children to the elderly, each person took one bi (a small spoonful), ensuring lifelong immunity from all toxic diseases. This is also the method of Tusu wine used by ancients. I heard this account from Yu Mian, a scholar in Hangzhou.

The Sigan City tribe in the Western Regions (Uyghur area) produces over ten types of medicinal herbs unknown in China, which are highly effective in treating diseases. One is called Ajier, resembling *Kushen* (Sophora flavescens root), used to treat horse rat sores, fetal injury in women, and internal trauma from falls or blows. Swallowing a bean-sized dose causes the condition to resolve spontaneously. Another is called Axier, resembling *Digupi* (Cortex Lycii), used to treat retained placenta after childbirth and to promote pus discharge from open wounds (Jin Chuang); chewing and applying it to the wound facilitates pus drainage. A third is called Nugesar, resembling *Jiegeng* (Platycodon grandiflorus root), used for open wounds and severed intestines or tendons; chewing and applying it promotes spontaneous healing. In Uyghur regions, there is a spider-like insect whose venom causes fatal thirst and death upon contact; however, drinking excessive grape wine and inducing vomiting can detoxify it.

To the west of the Huihui Kingdom grows a highly toxic substance resembling a human form, similar to ginseng, named Yapulu. It grows deep underground. If anyone damages its skin during extraction, the toxic vapor will kill them upon contact. To extract it safely, one must first dig a large pit allowing space for people around it. Then, gently encircle the plant with a leather strap tied to the foot of a large dog. Beating the dog causes it to run away, pulling the plant out. The dog dies upon smelling the plant's odor. The dog is then buried elsewhere. After a year, the plant is retrieved, dried in the sun, and processed with other drugs to mitigate its toxicity. If a small amount is ground into wine and consumed, the drinker becomes paralyzed throughout the body and dies, feeling no pain even if cut with knives or axes. Three days later, administering a specific antidote revives the patient. In ancient times, when Hua Tuo treated illnesses unresponsive to acupuncture and herbs, he had patients drink wine and take Mafeisan until unconscious, then performed abdominal surgeries. It is likely that Yapulu was this drug. (From *Zhinya Tang Zha Chao*)
