Sea cucumber has lived on the earth for 600 million years and is the only living fossil on the earth. Sea cucumber, the best of marine life, has high nutritional and warming value. In particular, Stichopus japonicus, which is abundant in Bohai Bay, China, is well-known at home and abroad, and is known as the "king of ginseng". Xie Zhao's "Five Miscellaneous Groups" says: "Sea cucumbers are found on the seashore of Liaodong, and their nature is warm and tonic ... enough for the enemy to participate, so they are named sea cucumbers".

"Compendium of Materia Medica" contains "Stichopus japonicus, which is found in three seas, and its nature is warm and tonic, which is enough for the enemy to participate". It has the functions of tonifying deficiency, moistening dryness, promoting blood circulation and dredging collaterals. Its main components, holothurin and mucopolysaccharide, have four anti-effects: anticoagulation, anti-aging, anti-radiation and anti-tumor, so it ranks first among the eight treasures in the ocean. As one of the "eight treasures of seafood", sea cucumber is warm and sweet, and has the effects of tonifying kidney and essence, nourishing blood and moistening dryness. The nutritional value of sea cucumber is extremely high, the content of protein is extremely high, and it contains no cholesterol, so it is a nourishing treasure.

Modern medicine has proved that sea cucumber contains more than 50 kinds of nutrients beneficial to human physiological activities, among which protein is extremely high, including 18 amino acids, taurine, chondroitin sulfate, Stichopus japonicus mucopolysaccharide, calcium, phosphorus, iron, iodine, zinc, selenium, vanadium, manganese and vitamins B 1, vitamin B2, niacin and so on. Of the 18 amino acids, 8 are essential amino acids that cannot be synthesized by human body itself.
