The cornflower plant covers the golden prairies from late spring onwards with its elegant blue flowers. For hundreds of years, the seeds of crops have been mixed with cornflower seeds and dispersed worldwide.  Pliny the Elder, a 1st-century Roman botanist, portrayed the cornflower plant as “an annoying flower for harvesters,” who did everything they could not to cut it with their sickles and scythes. Also, other classical writers have given us other positive words about this delicate plant.

The medicinal virtues of the cornflower plant were discovered by Mattioli, a 16th-century botanist who declared that “the blue flowers of this plant alleviate reddened eyes.” The healing virtues are a result of, according to Mattioli, the blend of opposite colors, red vs. blue, following the theory of signs.

Cornflower water, obtained by the decoction of its flowers, is primarily used in applications on the eyelids due to its notable anti-inflammatory effect. Eye irrigation and baths with cornflower water ease itching and eye irritation, besides giving a fresh and smooth look to tired eyelids. Thus, in many places, this plant is given the name of “bags-under-eyes.”

People who wash their eyes with cornflower water obtain a limpid and shimmering gaze, which flashes just like the cornflower’s tiny blue flowers in golden wheat fields.
