While many people think that buckwheat is a cereal grain, it is actually a fruit seed that is related to rhubarb and sorrel making it a suitable substitute for grains for people who are sensitive to wheat or other grains that contain protein glutens. Buckwheat flowers are very fragrant and are attractive to bees that use them to produce a special, strongly flavored, dark honey.

Excellent source of manganese and magnesium and a good source of iron, calcium and selenium. Also rich in amino acids lycine and tryptophan. Buckwheat also contains rutin, a heteroside with Vitamin K activity, which strengthens fragile capillary walls. Rutin thus encourages good circulation. Flavonoids like rutin, are phytonutrients that protect against disease by extending the action of vitamin C and acting as antioxidants. Buckwheat's lipid-lowering activity is largely due to rutin and other flavonoid compounds. These compounds help maintain blood flow, keep platelets from clotting excessively (platelets are compounds in blood that, when triggered, clump together, thus preventing excessive blood loss, and protect LDL from free radical oxidation into potentially harmful cholesterol oxides. All these actions help to protect against heart disease.
