Corruption is a consistent problem in my world. It damages the environment and changes the wildlife. But there is a method to deal with it. Humanity is able to mark the ground with intricate symbols that draw in the corruption. And by providing certain materials the corruption can be turned into a material form and fought, defeated, or even captured.

Capturing corruption allows one to purify it over time and then return to the area it was captured to improve its form. 

Over time the corruption beast will need to recharge, meaning you need to enter a corrupted area, or the creature will go dormant until this is done. 

The materials needed are the following:

Fluid - the healing and distribution method in all living things. Be it blood, sap, egg yolk.

Muscle - the sturdy parts of the beast. Exoskeletons, bones, muscle and wood.

Flesh - the elastic parts of living entities. Skin, scales, joints, leaves.

Bloom - the materials of survival. Common materials include pollen, honey, fruits and berries.

Wither - the martials of death, after all, nothing can live forever. Alcohol, bacteria, rotting substances like egg yolk or fat.

Vessel - a container for the creature. Must be made of an inorganic material, such as stone, ceramic, or metal.

A hypothetical use of magic in my world. Alchemical Summoning and Capture.
