Exorcism

This is a major step up from parasite removal as there are times when powerful demonic entities can start living inside people and feeding off their energy.  As you can imagine, negative beings like fear, pain and suffering so they love to foster that inside a person if they get the opportunity. 

In times gone past, a priest would have turned up with a crucifix or a witch with an amulet, both able to expel demons using wisdom and technology.  In this quantum age a remote energy healer can expel the demons without having to turn up anywhere with anything.

All demons are expelled in an environmentally friendly way and not left to run amok and infest others.  They are banished via portal to their next destination, leaving the person free.
