Carrot - 'A carrot' is the only description this item has.It's possible they could have been another healing item, or one of many 'quest' items needed to help a town improve. Aloe Leaves - The description states that they're 'Leaves from an aloe plant'.
None of them have any effect in-game, however. For instance, use Pro Action Replay (PAR) code 7F8000? (where '?' is one of the numbers listed below) to put that item in the first slot of your inventory. There are a number of items in the game which can only be obtained by hacking.
