Overview
Cornflower grew wild among Persian wheat fields — hence its Persian name 'wheat flower.' The brilliant blue petals have been used in Persian, Anatolian, and European folk medicine for centuries, most famously as a compress and eye-wash for tired, irritated eyes. The plant is cool and slightly drying, mildly bitter, and a classical companion to chamomile and rose in calming eye and skin formulas.
