Health pack

Summary
On the battlefield, Marines, and even Spartans need to have health packs, or MedKits, available. Each MedKit contains small stores of BioFoam (see below), a stitch kit, sedatives, bandages, and other useful field dressing components.

BioFoam is a healing, coagulant foam that is inserted into the skin and even deeper into the body itself. This foam keeps damaged organs in place and helps stop bleeding and hemorrhaging. It is, unfortunately, very painful to use.

These are only present in the first Halo video game. In Halo 2, health regenerates with an integrated Biofoam dispenser.
