Cornflower
Centaurea cyanus
Cornflower has ridden along in European grain fields for centuries, so entwined with wheat and rye that old herbalists simply called it the cornflower, corn being the old word for any grain. Young men once tucked the blossom into a buttonhole to signal they were courting, and folklore held that if the flower wilted too quickly, the love was doomed to fade just as fast, which is how it earned the name bachelor's button. Herbalists in the German and French countryside dried the petals for teas meant to settle the stomach and brewed cooled infusions to soothe tired eyes after long days in the sun or at close needlework. The vivid blue petals also found their way into inks, dyes, and wine to lend color long before synthetic dyes existed.

Traditional preparations.
A traditional mild infusion sipped after meals, valued in old herbal practice as a gentle bitter for digestion and as a calming evening cup.
Steep 1 teaspoon of dried cornflower petals in 250 ml of just-boiled water for 8 to 10 minutes, then strain and drink warm.
A folk remedy for tired, puffy eyes after a long day, using the cooled tea on the closed eyelid rather than as a rinse.
Brew a cup of cornflower tea as above, let it cool completely, then soak a clean cloth or cotton pad in the liquid and rest it over closed eyes for 10 minutes.
Safety.
Cornflower petals are commonly eaten as a garnish and are safe in normal amounts, though people sensitive to ragweed, daisies, or chrysanthemums may react to it.
