Prickly Pear

Prickly Pears are dropped by Cacti in Desert biomes and can be used for crafting a Cactus Potions, which are essentially a slower healing version of a regular Life Potion.

Prickly Pears and Cactus Potions, while healing the player slower than regular Life Potions, are often easier to obtain due to the fact that one Cactus can drop up to three Prickly Pears upon destruction.
