Many patients and their families often ask in the clinic: Can we eat sea cucumber? What is the efficacy of sea cucumber? Effectiveness】In terms of Chinese medicine theory, sea cucumber can nourish liver and kidney, nourish Yin and dryness, and nourish blood, so it has a very good tonic effect during radiotherapy, which can quickly improve the body’s physical strength and immune system. Sea cucumber itself contains a substance called sea cucumber toxin, which can not only inhibit the growth of many kinds of molds, but also inhibit the growth and metastasis of cancer cells, playing a role in cancer prevention and anti-cancer. In addition, the iodine contained in sea cucumber is an essential element for thyroid hormone; the vanadium contained in sea cucumber can participate in the transport of iron in the blood and enhance the hematopoietic function of the body; the chondroitin sulfate contained in sea cucumber can inhibit the aging of muscles and has an anti-aging effect; the selenium contained in sea cucumber is one of the essential trace elements of the human body and has an obvious anti-cancer effect. According to the latest research data from the national medical community, the selenium content in cancer patients’ bodies is 3-6 times lower than that of normal people. A large number of pharmacological studies have confirmed that high quality sea cucumber is also rich in sea cucumber mucopolysaccharide and sea cucumber saponin. Sea cucumber mucopolysaccharide can improve the number of human macrophages and its phagocytosis ability, reduce the total amount of cancer cells in the body and prevent cancer from occurring. For cancer patients, sea cucumber mucopolysaccharide can reduce the replication of cancer cells and inhibit the metastasis of advanced cancer cells. Sea cucumber saponin, on the other hand, can destroy the capillaries inside the tumor, reduce the blood supply to the tumor and make the tumor shrink, which is called “natural catheter intervention”. Of course, it is necessary to know the amount of food and try to diversify the food intake.
