If held by a Pokémon, it restores the user’s HP in a pinch, but it will cause confusion if the user hates the taste.

Effect:

Held in battle : When the holder has 1/2 its max HP remaining or less, it consumes this item to restore 1/8 its max HP. If the holder dislikes sour flavors (i.e., has a nature that lowers Defense), it will also become confused.
