In reply to: Weird thing about citrus oils posted by Lauren on October 22, 2002 at 02:04:52:

Faery Ring is right, it is the furocoumarins that are removed to
render the oils safer. Note the ending there, safER. Citrus Oils are
still known for sensitising skin. Lemon oil, I have read, can still
be quite photosensitising even after distillation of those agents.

Distillation and expression are processes for extracting oil. As I
understand it, the two different processes yield two different
results. It's like the difference between squeezing your oranges to
get the juice, or soaking them in a chemical compound which you let
evaporate so you are left with orange juice. The two juices will have
different properties because of these different processes. Just
another thing to keep in mind when buying oils. A good supplier will
tell you just how their oils are made.

Folded oils are distilled and end up having properties that are
beneficial removed. This is for the end use that involves scent and
taste. I can't see folded oils having any use in aromatherapy,
natural care or henna. But that is my perception based on what I've
read. Just a disclaimer as I could find something that changes my
mind, but... I doubt it!

Something to keep in mind about citrus oils is that they are used as
industrial solvents and cleaners. Another thing to remember is that
oils that are said to be photosensitising are affected by UV light,
not just sunlight. You can get a sunburn even on an overcast day-
that's the UV light. Something to remember if you are using these
oils. Or using herbs, like St. John's Wort, known to be
photosensitising. Just a little caveat there!
