Onions are bulbous vegetables of the Allium genus. Like their relative garlic, onions are common allergens.
Onions are a significant source of a variety of polyphenols, notably phenolic acids and flavonoids. Onions are a common allergen; it is not uncommon for an individual to be allergic to raw but not cooked onion, though others are allergic to it in both raw and cooked form.
Onion can be toxic to most pets, in raw and cooked form.
