Fish bladder, commonly known as fish foam, its main components are high-level collagen, mucopolysaccharides, and contains a variety of vitamins and calcium, zinc, iron, selenium and other trace elements. Chinese medicine believes that: fish swim bladder is sweet and flat, nourishes blood and stops bleeding, and nourishes the kidney and fixes the essence. The use of fish dart with traditional Chinese medicine can treat peptic ulcer, tuberculosis, rheumatic heart disease, aplastic anemia and vasculitis and other diseases. Recently, our medical workers also found that swim bladder can enhance the digestion and absorption function of gastrointestinal tract, improve appetite, and help to prevent and control loss of appetite, anorexia, dyspepsia, bloating, constipation, etc. Fish bladder can also enhance the toughness and elasticity of muscle tissue, enhance physical strength, eliminate fatigue; it can also moisturize the skin, make the skin delicate and smooth; it can also strengthen the brain and nerve and endocrine function, promote growth and development, maintain the normal secretion of gland, and can prevent and control mental retardation. It can also strengthen brain, nerve and endocrine functions, promote growth and development, maintain normal secretion of glands, and prevent and control mental retardation, slow nerve conduction, slow reaction, pediatric dysplasia, insufficient milk secretion of mothers, and insomnia in old age, etc. Since swim bladder contains a lot of gelatin and has the effects of activating the blood, tonifying the blood, stopping the bleeding, preventing cold, and dispelling dampness, it can improve the immunity of the organism. Fish bladder is cooked into dishes with soft and glutinous lubrication and delicious flavor. Folk often before and after the winter solstice, the swim bladder and cinnamon, red dates, walnuts and yellow wine stew. Fish bladder can also be used to make medicinal meals. The following two may be worth a try. Fish bladder five soup: swim bladder 12 to 15 grams, 19 grams of Sha Yuanzi, dodder 12 grams, chasteberry, wolfberry 15 grams, 9 grams of schizandra, six **** decoction, boiling water for 1 hour after drinking soup, 1 dose per day, divided into 2 times. It is used for tonic for kidney deficiency, and also treats spermatorrhea, lumbago, tinnitus, dizziness, and blurred vision. Fish bladder glue is a traditional Chinese medicine application of valuable drugs, sturgeon, sturgeon swim bladder made of, used to treat kidney deficiency and spermatorrhea, vomiting blood, and so on. However, due to the lack of resources, it is now mainly processed into swim bladder gelatin or swim bladder gel beads for medicinal use from the swim bladders of yellow-lipped fish, yellow croaker, small yellow croaker, fish, cod, moray eel, and freshwater carp, catfish, etc. The collagen from the swim bladders is different from that of the other species. Because of the different sources of collagen, its amino acid composition is also different, generally aquatic animals and other mammals gelatin is generally similar, of which glycine accounted for about 1 / 3, alanine accounted for about 1 / 9, proline and hydroxyproline about 2 / 9, these four amino acids *** accounted for the total amino acids of about 67%, followed by glutamic acid, arginine, aspartic acid and serine *** accounted for the total number of amino acids about 20 , others such as histidine, methionine and tyrosine are extremely low in content [23]. Collagen fibers intertwined with each other into a mesh, collagen peptide chain of some hydroxylysine hydroxylate δ-hydroxyl connected to the galactose in the process of hemostasis is of great significance, once the body is subjected to trauma and bleeding, platelets are adhered to the surface of the collagen, and each other to further accumulate and reach the coagulant effect, therefore, in addition to swim bladder gelatine as a tonic, it is also effective in gastric ulceration, pulmonary tuberculosis, and women's collapse of the leakage of bleeding and other bleeding disorders. Therefore, swim bladder gelatin has good curative effect on bleeding diseases such as gastric ulcer, tuberculosis and women's bleeding. The collagen of fish skin is easy to be hydrolyzed and extracted to make glue, such as puffer fish skin glue, moray eel skin glue, horse face fish skin glue and shark skin glue, etc., which also has the effect of hemostasis and can be made into hemostatic sponge. Valuable shark fins that is shark fins, its elastic collagen can be made of shark fin glue, has been used as a good tonic strong agent. Fish scale collagen is also easy to hydrolyze made of fish scale glue, in addition to fish scale hard protein, need to add dilute acid or vinegar, in order to be dissolved by boiling, fish scale glue can be used to treat women's collapse in the band, and purpura, epistaxis, bleeding gums and so on have a certain degree of efficacy. And fish scales contain more ovalbumin, and water mingled with the role of delaying cellular aging.
