Daisies have been grown by humans for both aesthetic and medicinal purposes for many thousands of years, and were especially popular in ancient Egypt, with amulets in their likeness dating back as far as the Old Kingdom. This popularity could be attested to their healing properties, with wearers perhaps seeking protection or cures for certain ailments. Alternatively, images of daisies may have been a reference to the importance of natural cycles, as they open and close in accordance with the rising and setting of the sun.
