The skull, tibia, and vertebral column of the tiger are used as medicine. The meat is slightly salty. The matter concerning the "Yi bone" (a legendary bone) noted by Chen Cangqi, and the theory that its reflected gaze turns fallen objects into white stone, must have originated from human fabrication; ultimately, it cannot avoid being regarded as false accusations. Someone might ask: "Why does wind follow the tiger?" Wind belongs to Wood, and the tiger belongs to Metal. Since Wood is controlled by Metal, how can it not follow? Therefore, when the tiger roars, wind arises; this is the way of nature. Thus, tiger bone is used to treat conditions such as wind-induced spasms and tightness, inability to flex or extend limbs, wandering pain (Zou Zhu), epilepsy, convulsive disorders, and bone-joint wind toxicity, based on this principle.

The fur is reddish-yellow, with black patterns resembling coins that are hollow in the center, arranged closely in sequence. This beast is fiercer and more agile than the tiger; therefore, it can calm the five Zang organs, tonify severe injuries, and lighten the body. There is also a "local leopard," whose fur has no patterns, is not red in color, and is smaller in size. These are distinct species and cannot transform into tigers; sages merely used them as metaphors. Fearing that medical practitioners might not understand, I have recorded this.

The form resembles a cat, with two types of patterns: one like linked coins, and the other like tiger stripes. Both colors of civet cats can be used as medicine. Their meat taste is not far from that of foxes. In Jiangxi, there is a type called "ox-tail civet," whose tail resembles an ox's tail; people often pickle and eat it, but it is rarely heard of being used as medicine. Meng Shen said: "Use civet bone to treat hemorrhoids, prepared as a soup." Then how should the bone be made into soup? Roasted civet bone combined with Musk (Moschus) and Realgar (Realgar) formed into pills and taken orally is very effective for treating hemorrhoids and sores.

Rabbits with white fur fully possess the Qi of Metal and are especially efficacious when used as medicine. Other rabbits can be eaten only in late autumn, when the Metal Qi is complete. When spring and summer arrive, their taste changes. The hair from behind the four elbows is taken to feed eagles and hawks; the next day, they vomit up the food. The intention is to clear all fat from the bird's stomach, making it hungry and eager to hunt swiftly. However, when making rabbit paste, the five flavors must be balanced. If one suffers from smallpox/chickenpox (Wandou Chuang) and eats rabbit meat, the toxin may flare up severely, potentially causing disfiguring skin lesions.

The classics do not state the nature and flavor of rats. It is only mentioned in general medicines for difficult labor that rat is slightly warm, has reddish-black fur, and a long tail; humans catch them and use the skin to make warm hats. They can fly downwards but cannot travel far. They are abundant in the mountains west of the pass, with extremely dense fur; people call them "Feisheng" (Flying Life). The commentary also cites "Shuima" (Water Horse), which has a head like a horse, a body like a shrimp, a hunched back, and bamboo-joint-like patterns on its body, measuring two or three cun in length; it is now known as Seahorse (Hai Ma).
