Medicinal Actions & Uses

Used for a wide range of circulatory problems, buckwheat is best taken as a tea or tablet, accompanied by vitamin C or lemon juice (Citrus limon) to aid absorption. Buckwheat is used particularly to treat fragile capillaries (seen as small bruises with no apparent cause), but also helps strengthen varicose veins and heal chilblains. Often combined with linden flowers (Tilia spp.), buckwheat is a specific treatment for hemorrhage into the retina. Buckwheat is also commonly taken in combination with other herbs for high blood pressure.
