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. Although it can't be bought, it can be sold for nine coins.

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, there are only two ears of corn in the series: one in the first game and another in the second.
