Frozen eggs are a common ingredient in potions, particularly Love Potions. They can also be swallowed whole as an antidote to ague. An Ashwinder egg is essential to the creation of Felix Felicis.
Some enlarged Ashwinder eggs played a large part in the ending of the Hogwarts school pantomime tradition. In the play The Fountain of Fair Fortune, an Ashwinder was supplied by Professor Kettleburn to play the 'blind and bloated' worm. The Ashwinder was enlarged with the use of an Engorgement Charm; however things got out of control, and the Ashwinder laid its eggs. These eggs, presumed to be enlarged like the Ashwinder, set fire to the floorboards in the Great Hall and ended the Hogwarts pantomime tradition.
During the Calamity, which happened across the Wizarding world in the 2010s, wizards and witches who worked as volunteers for the Statute of Secrecy Task Force often collected and used these eggs, as ingredients for various potions brewed to help address the mysterious situation.
