Survival Sickness

Survival Sickness adds a deeper survival health system to Minecraft. Players can catch diseases from bad weather, mobs, unsafe food, desert heat, freezing, low sleep, wounds, and underwater strain.

To survive, you must prepare medicines, collect medical ingredients, use the Medicine Mixer, and trade with Doctor villagers.

This mod is made for survival, hardcore worlds, and multiplayer servers where health management should feel more meaningful.

Medicine Mixer

The Medicine Mixer is the main workstation used to create medicines.
