Growing environment: Black tartary buckwheat mainly grows in mountainous areas at an altitude of 2000 to 3000 meters, and the production area is mainly in plateau areasOn the other hand, tartary buckwheat mainly grows in areas with an altitude of about 1,500 meters, and its production areas are mainly hilly plains and small plateaus.
Nutritional value: Black tartary buckwheat is known as the "king of grains", and the content of bioflavonoid rutin in it is much higher than that of yellow tartary buckwheat, and the nutritional value is also higher than that of tartary buckwheat. Due to the high nutritional value and relatively small yield of black tartary buckwheat, it is relatively higher than that of yellow tartary buckwheat.
Efficacy: Black tartary buckwheat has a variety of health effects such as lowering blood sugar, lowering blood lipids, enhancing immunity, and promoting digestionThe yellow tartary buckwheat mainly has the functions of clearing heat and detoxifying, diuresis and swelling, moistening the intestines and laxative.
In summary, there are certain differences between black tartary buckwheat and yellow tartary buckwheat in terms of appearance color, yield, growth environment and nutritional value. For more information, it is advisable to consult the relevant literature or consult a botanist.
