For centuries, both the bulb and its protective layers have been cherished in traditional remedies and natural wellness routines. Packed with powerful antioxidants and essential nutrients, incorporating onions into your diet is a smart move, but learning to repurpose their peels unlocks an entirely new level of sustainable living and natural benefits.
