For many years, I could not be in a room where citrus had been peeled for many hours after the peeling. If any pieces of peel were left out, I couldn't go in the room. If the door to that room was open, I couldn't be in any adjoining room either and I reacted to the orange oil left on the hands of whoever peeled it.
As I began to heal, I was able to peel an orange under cold running water, with gloves and mask on.
In time I was able to remove the mask but still had to use cold running water and gloves and could not leave any of the peel out.
I hadn't tried it for almost a year until 2 months ago when I had a sudden craving for an orange and I decided to try peeling it like a normal person and see how I did.
I was fine!
What's more, I enjoyed the smell!
Also a surprise to me were the facts that I could leave the orange peel out without reacting and that I didn't react to the orange oil left on my hands.
This was all incredibly exciting to me (and still is :).
I love oranges and it's totally liberating to be able to peel one for myself, in my own home, with no ill effects! I've repeated the experiment a number of times since I first tried it a few months ago and I've been fine each time - actually enjoying the wonderfully fresh smell.

FYI:
I believe that concentrated orange oil 'cleaners', degreasers and solvents and essential oils are not safe to use. Unfortunately they are often marketed as 'natural', 'green' and 'non-toxic'.
