A. component: Nature buckwheat and wild buckwheat including abundance of chlorphyll, rudin, selenium and vitamin, which can take toxicity matter from body and have oxidation and adjust immunity. B. Efficacy The buckwheat is a valuable dietetic product, very light for a digestion, with many minerals and vitamins. The most important vitamin is the P vitamin - rutin which makes veins elastic and regulates a blood pressure. It has a favourable effect upon a blood system, a liver and a digestion. For example the buckwheat tea is made from buckwheat hulls and stalks (before it is in flower). This guarantee high level of the rutin. The buckwheat is a naturally gluten free product. Buckwheat has been consumed in Japan for thousands of years, and it has recently been found to be very effective in reducing high blood pressure and slowing the aging process. The most common way of using buckwheat in that country is in the form of buckwheat noodlesaidian greatly outnumber any other type of restaurants in Japan, because buckwheat is known to be highly nutritional and easily digestible. More specifically, buckwheat contains 31 percent more protein than brown rice and 43% more than polished rice. In particular, the buckwheat protein contains 8 kinds of amino acids in a well-balanced way, so it is considered superior to that of rice or wheat. In addition, buckwheat contains a great deal of B-group vitamins and minerals. C. Particularly notable nutrients in buckwheat 1. Rutin (a bioflavonoid) This special bioflavonoid is not found in other grains (rice, wheat, etc.) or beans, but is contained in great quantity in buckwheat. Rutin is important because it strengthens capillaries and so helps people suffering from arteriosclerosis (the hardening of the arteries) or high blood pressure. Rutin belongs to a group of plant compounds called bioflavonoids that also include the important catechins of green tea and the polyphenols of red wine. Recent studies have shown that the bioflavonoids are powerful antioxidants that fight free radicals. Free radicals are said to be responsible for as much as 90 percent of all the human diseases, such as cancer, arteriosclerosis, strokes, senility due to aging, etc. 2. Vitamin P This vitamin is similar to rutin in that it increases capillary strength. But it is important in its own right because it is necessary for the proper functioning and absorption of vitamin C. Although buckwheat is the only significant source of vitamin P, this vitamin is also contained in trace amounts in rose hips, cherries, blackberries, prunes, skin and pulp of fruits, vegetables, etc. This is why some vitamin C supplements contain rose hips in soft gels. 3. Choline This is a compound in the vitamin B complex that plays an important role in metabolism, lowers blood pressure, and hinders the deposition of fat in the liver. As a neutralizing agent, choline helps the function of the liver that has been particularly overburdened by alcoholic beverages. (This is why aidian buckwheat tea and wild buckwheat tea and buckwheat noodle soup is often offered in Japan to the guests of a heavy-drinking party as a midnight snack.) wild buckwheat tea have more validity.
