These are the usable items in the game. You can't buy these anywhere; the only way to get them is to win them from enemies. Major enemies generally drop a fixed number of certain items (usually Elixirs or wines), but occasionally some minor ones do as well. Obviously, you can't be too indiscriminate about using these; usually, you should rely on your innate recovery rather than on items. However, in a fight when recovery is needed fast, these may well save you. Both wines and Elixirs will permanently raise your statistics; however, they will randomly raise them by somewhere between one and four points, inclusive. This means that if you save your game before using them, then start using them, you can manipulate events such that you get the maximum bonus out of all of them. Also, if you take off all your equipment, you may have a higher chance of getting the higher bonuses.
