Buckwheat has triangular seeds and produces a flower that is usually white, although can also be pink or yellow. Buckwheat contains a glucoside called rutin, a phytochemical that strengthens capillary walls. One clinical study showed mixed results in the treatment of chronic venous insufficiency. Although it is not an actual cereal (being a pseudocereal), buckwheat can be used in the same way as barley to produce a malt that can form the basis of a mash that will brew a beer without gliadin or hordein (together gluten) and therefore can be suitable for coeliacs or others sensitive to certain glycoproteins.
