Habitats

Edible Uses

Leaves - raw or cooked like spinach[4, 183, K]. Not that wonderful raw, they improve somewhat with cooking[K]. The leaves are rich in rutin[171] (see below for more details) and so are a very healthy addition to the diet[K]. Seed - raw or cooked. A nutty flavour, though it has a somewhat gritty texture[K]. The seed can be soaked overnight in warm water then sprouted for a few days and added to salads[183]. It can also be ground into a powder and used as a cereal[2, 4, 9] when it can be made into pancakes, noodles, breads etc or be used as a thickening agent in soups etc[46, 183]. Rich in vitamin B6[160]. An excellent beer can be brewed from the grain[244].

Medicinal Uses

Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.



Buckwheat is a bitter but pleasant tasting herb that is frequently used medicinally because the leaves are a good source of rutin[238]. Rutin is useful in the treatment of a wide range of circulatory problems, it dilates the blood vessels, reduces capillary permeability and lowers blood pressure[238, 254]. The leaves and shoots of flowering plants are acrid, astringent and vasodilator[4, 141, 165]. It is used internally in the treatment of high blood pressure, gout, varicose veins, chilblains, radiation damage etc[4, 141, 165]. It is best used in conjunction with vitamin C since this aids absorption[254]. Often combined with lime flowers (Tilia species), it is a specific treatment for haemorrhage into the retina[254]. The leaves and flowering stems are harvested as the plant begins to flower and are dried for later use[238]. They should be stored in the dark because the active ingredients rapidly degrade in the light[238]. Some caution should be exercised in the use of this herb because it has been known to cause light-sensitive dermatitis[238]. A poultice made from the seeds has been used for restoring the flow of milk in nursing mothers[4]. An infusion of the herb has been used in the treatment of erysipelas (an acute infectious skin disease)[4, 244]. A homeopathic remedy has been made from the leaves[9]. It is used in the treatment of eczema and liver disorders[9].

Other Uses

A very good green manure plant, it can be used to reclaim badly degraded soils and subsoils[1, 18, 20, 201]. A blue dye is obtained from the stems[57, 106]. A brown dye is obtained from the flowers[4].

Cultivation details

A very easily grown plant, it prefers dry sandy soils but succeeds in most conditions including poor[57, 141, 171], heavy[18] or acid soils[141] and even sub-soils[160]. Prefers a cool moist climate, but it also succeeds in dry and arid regions[171]. Buckwheat is frequently cultivated for its edible seed and leaves, it can produce a seed crop in 100 days from sowing[141] and a crop of leaves in 8 weeks. There are some named varieties[183]. The seed ripens irregularly over a period of several weeks so it is difficult to harvest[141]. Plants have poor frost resistance but they are disease and insect resistant[166]. They inhibit the growth of winter wheat[18, 20, 201]. The flowers have a pleasant sweet honey scent[245] and are extremely attractive to bees and hoverflies[4, 171].
