The edible onion, Allium cepa, is a cultivated species in the Allium genus. All members of Allium have important dietary and medicinal properties.

The pomegranate (Punica granatum L.) is a fruit that belongs to the Punicaceae family. A University of Georgia extension publication indicates that its Latin name means “seeded apple.” Pomegranate consumption by humans has increased in recent years because of its purported health benefits.
