Buckwheat – benefits, uses and side effects

Buckwheat is a plant. People make flour from leaves and flowers. This flour can be used as food (usually in bread, pancakes and pasta) or as a medicine.

As a medicine, buckwheat is used to improve blood flow by strengthening veins and small blood vessels; to treat varicose veins and poor circulation in the legs; and prevent “hardening of the arteries ” (atherosclerosis).

How it works?

Buckwheat may help people with diabetes by improving the way the body handles blood sugar .

Early research shows that drinking tea for 3 months can prevent the legs of people with chronic venous insufficiency from becoming more swollen.
