These provide limited healing (+5 units of health), but do little to reverse the effects of major damage.
Nali Healing Fruit
This native plant has natural healing properties. When eaten, it can give you a 29-unit health boost. In multiplayer games, Nali Healting Fruits re-grow soon after they are picked.
Superhealth
Boosts your health by 100 units. Don't waste Superhealth by using it when you are close to full health (200 units). Wait until you need a big health boost before you pick it up. (Note: you can not exceed 100 health without one of these)
Armor
You will find many different types of armor throughout the game, all of which increase your resistance to damage from weapons and impact. Certain types of armor provide better protection from certain forms of attack. The more damage your armor absorbs, the weaker it becomes. Keep an eye on your Armor level indicator to see how much strength your armor has left. Once your armor level reaches zero, the armor no longer offers you any protection.
Asbestos Suit
Provides resistance to fire and heat damage.
Kevlar Suit
Works in conjunction with Armor to provide even greater protection from damage.
Anti-Toxin Suit
Prevents damage from Tarydium waste pools, and other toxic areas. Note: all protective suits increase your overall resistance to any sort of damage to some degree. Like armor, protective suits become weaker as they absorb damage.
