What are the remedies to lower blood sugar?

A fist-sized onion head, cut into 6 to 8 parts, soaked in a wide-mouthed glassware, add a bottle of red wine (750 grams), 8 days after each meal on an empty stomach before taking a small glass of wine, a week to drink; together with soaked onion head eaten, the effect is better. This formula has the effect of stimulating insulin secretion and lowering blood sugar.
