INSUFFICIENT RELIABLE EVIDENCE to RATE

• Cardiovascular disease (CVD). A meta-analysis of clinical research shows that taking buckwheat seems to improve some, but not all, markers of CVD risk. Buckwheat was found to decrease total cholesterol by 19 mg/dL, triglycerides by 22 mg/dL, and blood glucose by 15 mg/dL, but had no effect on blood pressure, body weight, insulin, or low-density lipoprotein (LDL) cholesterol when compared with a control group (100947). The patient populations included in this analysis ranged from healthy adults to those with diabetes or hyperlipidemia; it's unclear whether the results are consistent across patient groups or if the benefits are more pronounced in certain types of patients. The effects of buckwheat on cardiovascular events, such as myocardial infarction, stroke, or cardiovascular death, in patients with CVD, are unknown.
• Chronic venous insufficiency (CVI). Preliminary clinical research shows that drinking common buckwheat tea for 3 months attenuates leg swelling compared with placebo in patients with chronic venous insufficiency (37351).
• Diabetes. Preliminary clinical research shows that patients with type 2 diabetes who replace a portion of white rice or white flour with tartary buckwheat 50 grams three times daily for 4 weeks show a 3% reduction in fasting insulin and a 7% reduction in low-density lipoprotein (LDL) cholesterol compared to baseline. Patients who consume the standardized recipe containing white rice and/or white flour three times daily for 4 weeks show no significant changes in these measurements. Neither groups show improvement in fasting blood glucose or hemoglobin A1c levels (96063).
• Diabetic retinopathy. Preliminary clinical research shows that taking common buckwheat 1 gram three times daily for 3 months does not significantly improve visual acuity compared with baseline in patients with diabetic retinopathy (37358). More evidence is needed to rate the effectiveness of buckwheat for these uses.

General ...Orally, buckwheat seems to be well tolerated (11438,11442). However, allergic reactions to buckwheat can occur in some adults and children. Symptoms can include skin sensitization, allergic rhinitis, asthma, conjunctivitis, nausea, vomiting, and anaphylaxis (11435,11436,11437,96060,96061). Occupational exposure to buckwheat, or household exposure through sleeping on a buckwheat husk stuffed-pillow can cause sensitization, of which symptoms include allergic rhinitis and asthma (11437,11443).
