(Fish)

Grass carp (Ctenopharyngodon idella) [specifically enters the Spleen and Stomach]. As food, its flavor is rich. It is found in both rivers/lakes and ponds. It is fed with grass. It often mixes with bighead carp (Hypophthalmichthys nobilis), hence the name "Huan".
Also known as Kun. (Li Shizhen said: Grass carp is named so because of its mild and gentle nature.) If raised in a pond, its taste is sweet and warm, non-toxic. Li Shizhen stated that it warms and harmonizes the Stomach Qi, referring to this specific type. If raised in rivers or lakes, its feed is not entirely green grass; it often consumes filth and foul substances mixed in. Therefore, medical texts also state that eating it can trigger sores/ulcers. However, fish generally have a warm nature. Regardless of whether they are from ponds or lakes, when consumed by individuals with a Yang-dominant constitution, it naturally causes heat and agitation; when consumed by individuals with a Yin-dominant constitution, not only is there no risk of dryness/heat, but the warming and tonifying power is even less pronounced. The suitability of food should be adjusted based on the person's organ constitution first, which applies not only to grass carp.
Gallbladder (of the fish): Taste bitter, cold. Can treat any bamboo or wood splinters stuck in the throat. Dissolve two or three pieces in wine, take warm to induce vomiting, and the splinter will come out.

(Fish) Warms the Stomach and stops diarrhea
Tinfoil barb (Barbonymus schwanenfeldii) [specifically enters the Intestines, Stomach, Heart]. It is merely a small fish in rivers and lakes. Li Shizhen said: It is only a few inches long, narrow and flat in shape, resembling a willow leaf. Its scales are fine and neat, clean and white, lovely. Its nature loves to swim in schools, truly the most virtuous among small fish. Taste sweet, nature warm, non-toxic. According to texts, its main indications include warming the Stomach and stopping diarrhea, which demonstrates its warming power. Others say cooking and eating it can alleviate sorrow/worry; does this not imply that its habit of swimming in schools helps relieve human sorrow? From this, we can see the auxiliary role of food.

(Fish) Treats consumptive disease (Laozai) and blood ascites (Xugǔ)
Mandarin fish (Siniperca chuatsi) [specifically enters the Spleen and Stomach]. This is what is commonly known as Guiyu. Taste sweet, nature neutral, slightly toxic. According to texts, its nature is highly dispersing and promoting free flow. It is most effective for treating accumulated evil blood and water ascites in the abdomen. Therefore, it is most suitable for consumptive diseases. In the past, a person surnamed Shao suffered from consumption at age eighteen, unhealed for years. He accidentally ate Mandarin fish and recovered. Does this not reflect its nature of being highly dispersing and promoting free flow, capable of treating evil blood and parasitic ascites? However, it has twelve bones, corresponding to the number of months in a year. If one is accidentally choked by a bone, grinding olive pit (Canarium album) into water can resolve the issue, as fish fear olives the most. Placing the tail on soft carbuncles in children is beneficial. The gallbladder treats bone or wood splinters entering the throat, regardless of adult or child. If swallowed causing abdominal stabbing pain, taking it will expel them. (Collect large Mandarin fish gallbladders in the twelfth lunar month, hang them under the north eaves to dry in the shade. For choking incidents, use an amount the size of a soap bean, crush with wine, take warm. Vomiting will cause the splinter to exit with saliva. If not expelled, take again until expelled. Drink wine according to tolerance; none fail to expel.) If Mandarin fish gallbladder is unavailable, gallbladders from grass carp, black carp, or crucian carp can also be used.
