which citrus oils are phototoxic

[Guest guest]

Hi Everyone,

I wondered if anyone could tell me what citrus oils are photo toxic and

if it applies if expressed or distilled. My understanding was that

Sweet Orange was not, but Chrissie Wildwood in " The Encyclopedia of

Essential Oils " states that " ...Distilled orange is

phototoxic:........However, there is no evidence to suggest that

expressed sweet orange oil is phototoxic although it too contains

coumarins " . This is listed on page 146 of the 1998 edition.
