Corn

Corn is a consumable item in the Golden Sun series. When used, an ear of corn restores 100 Hit Points to a single party member. Its sell value is nine coins, and it can't be bought back.

Corn is unusual as far as consumable items go, as it is the first of the few non-stat-boosting consumable items to come in limited quantities; most other consumable items are either sold in stores or dropped by common monsters. As of Golden Sun: Dark Dawn, there are only two ears of corn in the series: one in the first game and another in the second.
