The dried flowers are used to make medicine. People take cornflower tea to treat fever, constipation, water retention, and chest congestion. They also take it as a tonic, bitter, and liver and gallbladder stimulant.
Do you want to add a bright pop of blue to a dish? Try doing it with cornflowers — an edible bloom that has a slightly sweet to spicy, clover-like flavour. Cornflowers are often used as a garnish; although, the flower can also be used as a natural food dye. Is also used as a botanical in some Gins, Vodka's and even special Bourbons.
