Point Swap

Point Swaps are items found in Paper Mario: The Thousand-Year Door. They are commonly sold at Glitzville Shop for five coins each. When used, this item will allow Mario or his partner to switch their HP and FP. This does not allow either stat to exceed its normal maximum; any "overflow" points are simply lost. Using a Point Swap when FP is 0 will successfully reduce the target's HP to 0, and apply whatever consequences normally occur.

Cooking
Cooking a Point Swap with another item has various results. For restoration items, an HP-restoring item will usually turn into an FP-restoring item of the same amount and vice versa. For attack and status items, the result is often an item that is conceptually the reverse or opposite of the first item, and again is usually reversible. Point Swap recipes aren't recorded in the Recipes journal except for those that create Poison Shrooms.
