The 60's of the twentieth century witnessed the outbreak of Keshan disease in our country. Under the instructions of Premier Zhou Enlai, the experts of our country specialized in the study of nutritional science and trace elements conducted a study on Keshan disease characterized by the major symptoms of myocardial necrosis and found that lack of selenium is the main cause for the occurrence of Keshan disease. With the supplemental intake of selenium, the said disease prevalent in the selenium-deficiency areas was brought under control. The study has proved the relationship of selenium with Keshan disease for the first time. At the end of last century, scientists further discovered through observation that selenium deficiency is one of the major factors for hypertension syndromes, coronary, blood-deficiency myocardial infarction, atherosclerosis, etc. Research over many year has found that supplemental intake of selenium may help clear away the harmful substances like fat peroxide in blood vessels and protect the integrity of the cell membranes of the arterial vascular walls, thus preventing atherosclerosis and playing a role in halting the forming of thrombus and guarding against myocardial infarction. Besides, it was also discovered that supplemental intake of selenium may lower cholesterol and triolein, and an adequate intake of selenium may also protect myocardial cells and prevent the heart from injuries and heart-attack from happening. An American questionnaire indicates that people who died of heart attack, cardiac-vascular diseases, stroke, hypertension, etc. in the selenium-deficiency areas are three times more than those from the selenium rich areas. There are two cities in Finland with drinking water rich in relatively high selenium, where the death toll from heart diseases is only one seventh of two adjacent cities with drinking water of low selenium content. WTO has already included selenium into one of the elements relevant to cardiac-vascular diseases.
Why can a sufficient amount of selenium ensure one's heart for injuries? The truth is that the metabolic process of the heart will produce a great deal of fat peroxide which causes damage to the cell walls, whereas glutamic peptide peroxide enzyme with selenium content may have them resolved, thus protecting the integrity of the myocardial cells. The activity of such enzymes decreases in case of lack of selenium, causing the peroxide to form a vicious cycle in the body where viruses go berserk with a heart failure ensued.
With Enshi Teas as raw materials, Nano-Selenium Rich Black Teas is prepared per "the three-step method of nano-preparation". For the purpose of preventing enzymes and selenium from being affected by high temperature, freezing and drying approach is adopted after yeasting before nano-tech preparation. One of the functions is that nano particles can absorb and eliminate free radicals, cholesterol, other fat peroxides of hypertension; the second is that they are beneficial to the release of anti-oxidization of abundant polyphenol and Vitamins C and E; the third is they release selenium elements good for cardiac muscles. In other words, nano particles, polyphenol, Vitamin C, Vitamin E and selenium element in Nano-Selenium Rich Black Tea are miraculously joined together to form the natural "heart-protection baby".
Selenium can play an active role in adjusting the body mechanism and enhance the immune system of human body, and is a trace element essential for life activities. Lack of selenium will result in 40-plus kinds of diseases to human bodies including cardiac, cerebral and vascular diseases, hypertension, stomach and intestine diseases, diabetes, asthma, hepatitis, cancer, AIDS, etc.. 2/3 of the areas in our country belong to those of low in selenium or short of selenium, and daily intake of selenium per person is far below 50microgram/day. A rational composition of diet will ensure the increase of intake of selenium.
Tea is a drink containing selenium. Some areas rich in selenium such as Enshi of Hubei and Ziyang of Shaanxi are abundant with selenium rich tea. The tiny molecules of organic and inorganic selenium and selenium proteins in the selenium rich tea can effectively supplement selenium elements of which human bodies are in dire need, but the conventional method of soaking the selenium rich tea can only supply 10% selenium elements into tea drinks. Given the selenium content is 3ppm-5ppm and daily intake of 5-6 g of selenium rich tea, only 2-3microgram of selenium element can be supplemented, which is far below the daily intake standard (50-200microgram) prescribed by WHO, and moreover 90% of the precious selenium rich tea is wasted away.
Prepared with nano-technology, the nano-tea can release effectively all the excellent essences of the tea, thus boosting the absorption (absorbing viruses, free radicals, cholesterol and blood lipid) and annihilation of viruses through penetration so that a good supplement of selenium has been achieved. With selenium rich tea from Enshi of Hubei as the raw material, Qinhuangdao Taiji Ring Nano-Product Company Limited has conducted a systematic study and development of nano-selenium rich tea with the self-developed patented technique--"Three-Step Method" of nano-tea preparation and its application, processed into six major categories of nano-tea and solved the dilemma of safe supplement of selenium rich tea and utilization of resources.
