  • Iris unguicularis Poir. Iridaceae. Algerian iris. Rhizomatous perennial. Distribution: NW Africa, E. Mediterranean It has scientifically-based potential. The rhizomes contain the chemical kaempferol which inhibits the enzyme alpha-glucosidase in the gut, reducing the rate of glucose absorption. This could be used to prevent the dangerous peaks of blood sugar that occur in diabetics and reduce eye and kidney complications. The unprocessed rhizome contains iridin, a toxic glycoside, which causes 'nausea, vomiting, diarrhoea and skin irritation'. Photographed in the Medicinal Garden of the Royal College of Physicians, London.
