Modern medicine has found that cancer is more likely to occur in people who have been under emotional stress such as mental depression, frustration, bitterness, fear and sadness for a long time. This is not an alarming statement! Although mental and psychological factors do not directly cause cancer, they often affect and lower the immunity of people with a chronic and continuous stimulation, increasing the incidence of cancer. However, if the mood can be adjusted artificially, some external “harm” is inescapable. Looking around us, electronic pollution is also a problem that cannot be ignored. These electrical appliances emit radiation. The high magnetic field can cause a kind of element called radon to accumulate around the human body, which may cause the human body to contact with more than 40 kinds of cancers. Sea cucumber, never a good thing in the tonic category. Recently, American researchers have extracted a substance from sea cucumber, and this compound can effectively hinder the growth of certain human cancer cells (including pancreatic cancer). Many Chinese herbalists in China have also successively stated that sea cucumber has a strong effect to fight the damage caused by electromagnetic radiation and radon to human body. After years of clinical research, sea cucumber has been found to have a very strong tonic effect. According to the theory of Chinese medicine, sea cucumber can nourish liver and kidney, nourish Yin and dryness, and nourish blood, therefore, it has a good tonic effect during radiotherapy, which can quickly improve people’s physical strength and immunity. Moreover, sea cucumber itself contains a substance called sea cucumber toxin, which can not only inhibit the growth of mold. It can also inhibit the growth and metastasis of cancer cells, playing a role in preventing and fighting 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 for human body and has an obvious anti-cancer effect in itself. According to the latest research information of the national medical community, the selenium content in the body of cancer patients is 3 to 6 times lower than that of normal people. A large number of pharmacological studies have also confirmed that high-quality sea cucumber is also rich in sea cucumber mucopolysaccharide. It can improve the number of macrophages in the body and its phagocytosis ability, reduce the total amount of cancer cells in the body and prevent cancer from occurring. For patients, it can reduce the replication of cancer cells and inhibit the metastasis of late stage cancer cells. Sea cucumber can improve the tolerance of cancer patients to radiotherapy and chemotherapy, reduce post-operative infection and accelerate wound healing. Therefore, sea cucumber is widely used in the treatment of liver cancer, stomach cancer, breast cancer, lymphoma, uterine cancer, rectal cancer, blood cancer, bone cancer, brain cancer, nasopharyngeal cancer and post-operative patients’ recovery. Therefore, sea cucumber is called the “king of anti-cancer”.
