Aromatherapists competence to prescribe internal use
I can say with a fair amount of knowledge on this sub)ect, that few aromathera*ists are what I would
consider ade0uately trained in *athology and diagnosis. Those sub)ects are critically im*ortant,
because if do not know how to differentiate between someone having a sim*le stomach u*set, or a
ma)or gastrointestinal tract disease, then giving oils internally is *laying with fire. Even on those
courses that teach the internal use of oils, the sub)ect of clinical diagnosis is a**allingly inade0uate.
In addition, on most such courses, the use of essential oils is taught on which there is no safety data
available and on which there is scant evidence of thera*eutic efficacy. I have here evidence on such
matters from so called /leaders in the field/. %or euba
In the wide variety of &romathera*y books and *eriodicals available today, we find many
recommendations regarding the safe, thera*eutic use of essential oils, often contradictory and seldom
su**orted by either references, research or actual clinical e

Why is there such a diversity of opinion regarding essential oil toxicity?
Three reasons a**ear to me outstanding 5 that of 2*hiloso*hical2 differences, the lack of knowledgeamongst *ractitioners and authors and the fear of *ublic misuse.

In terms of the most common uses of essential oils in &romathera*y, it is the acute ';- dose that is
most relevant in this consideration. This is considering thera*ists using essential oils on their clients
and *re*aring formulations for the client to use outside of visits.

3nternal useIn Euro*e, some *eo*le use essential oils internally@ They mi< them with an oil5
soluble li0uid such as honey, olive oil, or soy milk. #$'( use +--7 *ure essential oils that
have been a**roved for internal use 3such as lemon, orange, *e**ermint, gra*efruit, etc. 5
consult the >1&" list4, and only one dro* at at time at first, unless you are used to taking
more. Taking too many essential oils internally can cause intense healing reactions and can be
E1( uncomfortable. However, one dro* of *e**ermint, orange, lemon or gra*efuit added
to a glass of water can be very refreshing and healing. It is rarely necessary to use more than
this internally.

"kin irritation can occur from contact with undiluted essential oils. Be *articularly careful when using
aniseed, basil, cinnamon, citronella, clove, fennel, ginger, lemon, lemongrass, lemon myrtle, may
chang, *ine, sage, tea tree and thyme. These essential oils may irritate or cause sensitisation to the skin
in some individuals, more so than other essential oils. &nyone who knows they have sensitive skin
should always use a low dilution when a**lying oils to the skin.

uring *regnancy, many aromathera*ists consider it *rudent to avoid the use of aniseed, basil, bay
laurel, cedarwood, cinnamon, citronella, clary sage, clove, fennel, hysso*, )uni*er berry, sweet
mar)oram, myrrh, nutmeg, *arsley, *e**ermint, rose, rosemary, sage and thyme, because of the belief
they may harm the foetus or involve some risk of miscarriage. 3?4
The latest research available by Tisserand and Balacs suggests that most of these oils are safe during
*regnancy as long as they are not taken orally and the directions for use are followed. & ma

*ennyroyal, sassafras and wormwood. I would also add wintergreen to this list. Even though it is listed
as an oil not to be used in aromathera*y at all, it is still widely available. It is also very im*ortant that
anyone taking warfarin medication should avoid wintergreen essential oil because it has established
incom*atibilities, even when a**lied to*ically. 3:4
