Buckwheat is also used to treat diabetes.
Insufficient Evidence to Rate Effectiveness for...
- Varicose veins and other circulatory problems (chronic venous insufficiency). Early research shows that drinking buckwheat tea for 3 months might prevent the legs of people with chronic venous insufficiency from becoming more swollen.
- Diabetes. Early research suggests that eating 70-100 grams of buckwheat flour or grain daily may improve long-term glucose tolerance in people with diabetes.
- Vision problems in people with diabetes. Early research suggests that taking buckwheat by mouth for 3 months might improve vision in people with visions problems due to diabetes.

Special Precautions & Warnings:Pregnancy and breast-feeding: There is not enough reliable information about the safety of taking buckwheat if you are pregnant or breast feeding. Stay on the safe side and avoid use.
Buckwheat allergy: Some people who are exposed to buckwheat on the job develop buckwheat allergy. Other people can also become allergic to buckwheat. Re-exposure to buckwheat can lead to serious allergic reactions including skin rash; runny nose; asthma; and a potentially fatal drop in blood pressure, itching, swelling, and difficulty in breathing (anaphylactic shock).
Celiac disease or gluten sensitivity: Some researchers think that including buckwheat in a gluten-free diet might not be safe. However, buckwheat is considered an acceptable food by the Celiac Disease Foundation and the Gluten Intolerance Group. People with celiac disease or gluten sensitivity can probably eat buckwheat safely.
Allergy to rice: Some people who are allergic to rice might also become allergic to buckwheat.
Diabetes: Buckwheat might lower blood sugar levels. There is a concern that it might interfere with blood sugar control in people with diabetes. The dose of diabetes medication might need to be changed.
Surgery: Buckwheat might lower blood sugar levels. There is a concern that it might interfere with blood sugar control during and after surgery. Stop using large amounts of buckwheat at least 2 weeks before a scheduled surgery.
