A leaf decoction from BREADFRUIT tree is taken in Trinidad to treat diabetes. The complaint was treated in Russian folk medicine by strict diet, with an infusion of BILBERRY leaves — a tablespoonful to a cup of boiling water, infused for half an hour. PERIWINKLE used to be an Irish (County Cavan) treatment for the condition. In Africa, the seed of the BLUE LOTUS (Nymphaea caerulea) has been used for the condition. GINGER has been used for diabetes, in the form of juice, mixed with sugar candy! In America, an infusion of SPINY COCKLEBUR plants before they flowered has been used. HERB ROBERT is recorded as being a diabetes remedy in Ireland — a handful of the herb to a pint of water, in wineglassful doses, night and morning.
