@bluenite, Hoping you get some responses to your question about using essential oils to help with the difficult symptoms of neuroborreliosis. I did a search of Connect and found only one member who had mentioned neuroborreliosis in a post here - https://connect.mayoclinic.org/comment/177392/ but the member is no longer active on Connect.

Thought I would share a couple of references in case you have not already seen them.
