The healing item that restores 25 health over time is the Syringe.
In Apex Legends, a Syringe is a small consumable healing item used to restore a player’s health rather than their shields. Using one restores 25 health over five seconds, making it useful after taking damage when a player does not need the larger recovery provided by a Med Kit. Syringes are common ground loot and can be carried in stacks.
The main distinction is between health and shields. A Shield Cell restores 25 shield points, while a Syringe restores 25 health points. A Phoenix Kit restores both health and shields but takes much longer to use, and a Med Kit restores substantially more health than a Syringe.
Players often choose Syringes when they need a quick, relatively low-commitment heal or want to conserve larger items. Healing can be interrupted by movement or combat, so using one safely usually requires cover. The exact usefulness of a Syringe can also depend on a Legend’s abilities, armor state, and whether the squad is preparing for another fight.
