The cover picture shows Galega officinalis, commonly known as goat's rue or French lilac. The botanical name comes from the lactogenic properties of one of its extracts (from the Greek Gala, meaning milk, and agein, meaning to provoke). Extracts contain the alkaloid galegin, a derivative of guanidine. 'Tea against diabetes prepared from Galega officinalis' is sold on the internet. Although metformin is the gold standard treatment for type 2 diabetes, less attention has been paid to its use in type 1 diabetes. In the present issue of Diabetologia (53:2264-2265) H. Schatz reports a decrease in insulin requirements with metformin treatment in type 1 diabetes, but no improvement in glycaemic control.
