Similar to Bianyu (a scaleless fish), it is primarily used for various tonifying effects. It is scaleless and toxic; do not consume in excess. Those with red eyes and red whiskers are lethal. [Meng Shen's Annotation]
(1) Consuming it stabilizes Stomach Qi, harmonizes the Middle Jiao, benefits the Five Zang Organs, and is excellent when prepared as a soup. [Chen Cangqi's Annotation · Meng Shen's Annotation]
(2) Prepared as porridge, it treats acute dysentery. Consumed with garlic, it has a slight heat property; consumed with ginger paste, it has a slight cold property. [Sun Simiao's Annotation · Meng Shen's Annotation]
(3) Additionally, it can be eaten for summer heat-dysentery, providing greater benefit. In winter, it has no therapeutic effect. [Meng Shen's Annotation]
(4) Bones: Burned into ash and applied to malignant sores, it heals after three to five applications. [Meng Shen's Annotation]
(5) Furthermore, Crucian Carp (Jiyu) and Bianyu have similar appearances but distinct tastes. Bianyu is transformed from insect larvae. Crucian carp is transformed from Panicum miliaceum (Broomcorn millet); its belly retains the color of the millet. The wider variety is Crucian carp, while the one with a high back and narrow belly is Bianyu, which is less effective than Crucian carp. [Chen Cangqi's Annotation]
(6) Note: Carp roe harmonizes the Middle Jiao and benefits Liver Qi. All fish spawn adhere to aquatic plants and soil. After the winter flood recedes, they do not rot. During the Sanfu days in May, amidst rain, they transform into fish. [Sun Simiao's Annotation · Chen Cangqi's Annotation · Meng Shen's Annotation]
(7) When eating Crucian carp, one must not eat sugar, as it causes intestinal parasites (Gan disease). For those suffering from heat-toxin due to Dan-Shi (mineral pill) ingestion, prepare a soup with the head of Zizania latifolia (Wild Rice Stem) and Crucian carp. Eating it for one or two meals will cure the condition. [Meng Shen's Annotation]
Benefits the Five Zang Organs and expels the twelve Wind pathogens. For those suffering from "Evil Qi" illness, prepare a carp soup, eat until full on an empty stomach, cover oneself with clothing, and lie down. Soon, sweat resembling white glue will emerge, flowing from the waist and legs. After the sweat ceases, bathe in Wu Mu Tang (Five Wood Decoction) and avoid wind for one day. Administer every three to five days thereafter to treat Damp-Wind. [Chen Cangqi's Annotation]
(1) Gallbladder: Primarily removes redness in the eyes and heat-toxin pain; instillation is effective. [Meng Shen's Annotation]
(2) Meat: Boiled plainly and eaten, it treats edema and leg distension, and directs Qi downward. Do not eat if there are old accumulations in the abdomen, as it harms the person. Those long-term users of Asparagi Radix (Tianmendong) should also avoid eating it. [Chen Cangqi's Annotation · Meng Shen's Annotation]
(3) If a bone splinter is stuck in the flesh, or if suffering from Wind-Water swelling and pain, burn Carp eyes into ash, insert into the wound, and allow the fluid to drain for healing. [Meng Shen's Annotation]
(4) Note: Fish blood treats pediatric Erysipelas (Dan Du); applying it cures immediately. [Meng Shen's Annotation]
(5) Scales: Burn until smoke ceases, then grind. Take one Fangcun Bi (square-inch spoonful) with wine to resolve postpartum stagnant blood. [Meng Shen's Annotation]
(6) Fat: Treats various types of Epilepsy (Xian); consumption is beneficial. [Meng Shen's Annotation]
(7) Intestines: Treats abdominal sores in children. [Meng Shen's Annotation]
(8) Brain Marrow: Do not consume with broad bean leaves (Dihuo Ye), as it leads to emaciation. [Meng Shen's Annotation]
(9) Its roe must not be consumed with Pig Liver. [Meng Shen's Annotation]
(10) Additionally, during preparation, always remove the two tendons on the spine and the black blood within the spine, as these are toxic. [Sun Simiao's Annotation · Chen Cangqi's Annotation · Meng Shen's Annotation]
(11) Grilled carp must strictly avoid smoke; do not let smoke enter the eyes, as it damages vision. Effects will manifest within three to two days. [Meng Shen's Annotation]
(12) Additionally, do not consume after epidemic febrile diseases (Tianxing Bing); recurrence leads to death. [Sun Simiao's Annotation · Chen Cangqi's Annotation · Meng Shen's Annotation]
(13) Additionally, carp living in sand and gravel contain toxins, mostly concentrated in the brain marrow; do not consume the head. [Sun Simiao's Annotation · Chen Cangqi's Annotation · Meng Shen's Annotation]
