Stim Canisters are your primary source of healing in Jedi: Fallen Order. BD-1 carries them and administers them to Cal with a quick press of a button. You start with a limited number, but you can find additional Stim Canister upgrades hidden in chests throughout the galaxy. Each upgrade permanently increases the number of stims BD-1 can carry by one. Prioritizing these upgrades is highly recommended, especially on higher difficulties, as they significantly improve your survivability. Always keep an eye out for chests, as these are often where stim upgrades are found.
