Medicine is combining plants and fabrics to create Salves, Pills, or Bandages.
To do this you need a Medicine Station. This will look like the crafting table with some bottles on it. In addition, plant types, especially Flax. You can also now craft a bucket and gather Muddy Water.
A Filter station is also needed. This will be a simple craft. You can add water from your bucket to the filter station and over time it will become pure. Muddy Water–>Pure Water.
Option 1: HANDCRAFTED: Flax–> Fabric
