Description

technical field [0001] The invention belongs to the technical field of medical technology or health food, and specifically relates to a new application of giant salamander mucus. Background technique [0002] The giant salamander (Andrias davidianus Blanchard) is a large amphibian, Cauracea, and Cryptobranchidae. Its common name is "Salamander". Currently there are only 2 genera and 3 species in the family Cryptobranchidae, of which there are 2 species in the genus Giant Salamander: the Chinese giant salamander (Andrias davidianus) and the Japanese giant salamander (Andrias japonicus); the Cryptobranchus genus is only distributed in North America. )A sort of. Giant salamanders are dioecious, lay eggs on rocks from July to August, and float with the water to hatch. The giant salamander has a wide and flat head, a big mouth and small eyes, short limbs, obvious folds on both sides of the skin, and many warts on the body. The giant salamander has poor migration ability and is...
