White Paper
Raindrop
Therapy
The
use of essential oils is an ancient practice dating back to Egypt.Like
many other practices with roots in the past, it has been highly commercialized
to the public. It should rightly hold a respected position in alternative,
complementary health practices. In some parts of the world, such as France,
it may be practiced with care and skill. However, the general public in
the USA, is still in an initiate stage of understanding the use and benefits
of the oils. As such, this white paper is intended to educate the consumer
of essential oils and practices which they may be exposed to in their explorations.
While there is a sense that because it is “natural”, they are safe”, this
paper is intended to give you information about a practice promoted within
one company. The practice is called “Raindrop Therapy”, and is promoted
within the Young Living Company. While this paper does not make comment
regarding the company or it’s product, it does take a critical stand against
the use of the oils in “Raindrop Therapy”.
In
the USA, The National Association of Holistic Aromatherapy (NAHA) has defined
standard curriculum for certification for“Aromatherapy
Practitioner”. There are persons performing “Raindrop Therapy” (RDT), who
have not received training, observing similar curriculum standards. These
public demonstrations and conferences have been presented to the general
public as well as audiences of health care professionals including physicians,
nurses, midwives, doulas, and massage therapists. The purpose of this paper
is to assert a position against the use of a technique called “Raindrop
Therapy” as it currently cannot be supported as a recognized aromatherapy
“best practice.” This position is intended to educate and inform the public
as a part of the role of members of the Aromatherapy Community.
“Raindrop
Therapy” technique as developed by Mr. Gary Young is not to be regarded
as a best practice because:
vIt promotes the unsafe use of essential oils, putting people at risk of skin irritation and
vThere is no published empirical substantiation to support its claims that RDT is a “tool for assisting the body in correcting defects in the curvature of the spine, such as scoliosis.”[1]
Current
research of formal testing regarding the chemical structure, per cutaneous
absorption and dermal metabolism of essential oils as well as potential
skin reactions, including irritation, sensitization, phototoxicity and
essential oil toxicity, determines existing standard safety guidelines.Safety
guidelines are based on the assumption that essential oils used in aromatherapy
will be used at safe dilution levels for external use.
In
addition to standard dilution guidelines, the aromatherapy practitioner
must be aware of those individuals who are identified as a greater risk
for developing potential skin reactions, including persons with known allergies,
history of asthma, eczema, psoriasis, fair-haired, light skinned, and those
with a history of multiple allergies and medical complications.[2]
(Although this procedure does not preclude sensitization, only potential
irritation), “in order to avoid potential skin reactions, those “at-risk”
should receive skin “patch-testing” at “double the concentration
planned to use, prior to application of each essential oil.”[3]
There
is no published clinical evidence to support that RDT has any correcting
value as a tool to be used to adjust spinal curvatures caused by scoliosis,
or align electric and structural elements, even if the essential oils were
to be used at correct dilution levels and the individual’s skin was patch-tested
prior to application. Therefore, because of the unsafe use of undiluted
essential oils as well as unpublished claims, “Raindrop Therapy” technique
as developed by Gary Young is not supported as a “best practice.”
The
discussion that follows will present a description of 1) Raindrop Therapy
technique along with 2) current known safety standard guidelines regarding
the dermal application of essential oils
used
in RDT practice and 3) literature regarding unfounded claims of the rationale
for use of RDT.

“Next
comes the application of the oils of thyme and oregano. Hold the bottle
approximately six inches above the skin and let five drops of each oil
drop from the bottle evenly spaced along the spine from
bottom
to top (sacrum to atlas or 1st cervical). Try to stay in the
electrical field as much as possible. It
does
not matter which oil is applied first. Apply one oil and then layer it
by gently spreading it evenly along
the
curvature of the spine. Apply the second oils the same way.You
don’t need large drops, and more is
not
better. Then apply 10 to 15 drops of the V-6 Mixing Oil to prevent any
discomfort…
…Now
apply the oils of Cypress, Birch, Basil and Peppermint in that order.
Apply four to five drops of the first oil along the length of the spine.
Layer it in by evenly spreading it with your fingertips.Then
do the same with the other three. Starting on one side of the spine, gently
massage the oils in along the spine. Do not work directly on the spine.
Do not force it or apply direct pressure. Start at the sacrum and use the
fingertips of both hands placed side-by-side, and in a circular clockwise
motion, work up the side of the spine to the atlas, pushing or pulling
the tissue in the direction you want the spine to move. This
technique
helps to create a “space” for the spine to move.After
finishing one side of the spine, walk around to the other side of the individual
and begin on the second side starting from the sacrum working
up
to the atlas.Repeat this two more
times.
Step

Pay
close attention because the back can become very hot!
The
heat will generally build slowly in intensity to where it will peak in
five to eight minutes and then cool down to where it feels pleasant. The
water in the towel drives the oils deeper into the skin. The more out of
balance, the more virus or bacteria activity in the body, or the more inflammation
in the spine, the hotter the area will become along the spine. Some people
will experience no heat, for some it will be mild and very pleasant, while
for others it may be hot and a little
uncomfortable. Pay attention to what the person is saying. Ask questions.
If it gets too uncomfortable, remove the towels and apply V-6 Mixing Oil
on the back and work it in. This will usually remove the heat in minutes.
After
putting the towels on, wait a few minutes to see how the person is responding.
If the back does not become very hot, have the person roll over so the
back is against the towels on the table. This usually creates more heat.”
Step

“Take
the four oils of Birch, Cypress, Basil and Peppermint, in that order,
and apply two to three drops of each oil along the inside of the lower
legs along the shin bone from the bottom of the knee area to the top of
the big toes. Apply one at a time and layer each oil in before applying
the next oil. Place fingers of one hand along the inside of the shin bone
just below the knee, work down to the ankle, and then along the foot up
to the top of the big toe using the Vita Flex Technique. Roll your fingers
up and then over onto the nails of the fingers, applying slightly more
pressure at the top of the roll and releasing as you come over onto the
nails. Short nails would be appreciated by the person on whom you are working.
Do this
three
times on each leg….”
Step

“Have
the person on the table roll back so he or she is again face down. Rest
the head in the head-cradle of the massage table again and make sure the
person is lying straight. Remove the towels
and then examine the spine. Corrections may or may not be visible. At this
point you may add another therapy as desired. Sometimes the desired results
do not come immediately, and yet the body will continue to respond for
days, at which time you may begin to see gradual changes…
This
is the basic Raindrop Therapy, although there are several variations. Everybody
is different, and what works for one may not work for another. Different
body types respond to the applications in ways not expected. Learn to be
sensitive to the person to whom you are working so that you can respond
to his or her needs.”
The
question is often asked, “How long does this application last? Again, everybody
responds
differently.
Generally speaking, the level of health and proper diet are key factors,
as are exercise and mental attitude. One application may last months for
one person, but then for another it may be necessary to have the application
done every week until the body begins to respond. The key is to retrain
the body. In some cases, you will have to develop a new memory in the tissue
in order for the body to
stay
where it should be. This may take a few weeks or even a full year.” 4
The
Video Presentation Variation
In
the video, in which Mr. Young describes the process, he uses the oils of
Oregano 4 drops, and 5 drops of Thyme. He also states that if there are
arthritic or compressed disks, then to use 6 drops birch, 3 drops
lemongrass,
4-5 drops marjoram, 4-5 drops cypress and a couple of drops of Peppermint.
He
further goes on to explain that certain essential oils are known to be
caustic to the skin, such as the citrus, coneriferous and spice oils, such
as clove, nutmeg. He states that these oils are OK to use neat as in drops
on the spine, but for a larger area, like the whole back, to dilute them
15-30 drops to one ounce, and children and the elderly should be 15 drops
to an ounce.5
The
practice of applying these essential oils undiluted to the skin is not
consistent with “best practice” taught in standard curriculum for professional
aromatherapy education recognized by NAHA. The use of the undiluted essential
oils promoted within Raindrop Therapy, are not supported in safety manuals.

Methyl
salicylate can be absorbed transdermally in sufficient quantities to cause
poisoning in humans. Topically applied methyl salicylate can potentiate
the anticoagulant effect of warfarin, causing side effects such as internal
hemorrhage. A similar interaction is possible, but by no means certain,
with other anticoagulants such as aspirin and heparin. Many liniments contain
methyl salicylate or wintergreen oil.
Comments:
There have been sufficient cased of poisoning by methyl salicylate or by
oils containing it that it would be prudent to avoid use of this oil in
aromatherapy. Virtually all ‘sweet birch oils’ are in fact synthetic methyl

Comments:In
light of its high thujone content, tansy oil should be avoided altogether
in aromatherapy.48
Some
Tansy oils contain very high levels of b-Thujone
which orally is extremely toxic and which does seem to be absorbed through
the skin.49
On the other hand some tansy oils contain no or insignificant amount of
this chemical so until such time as full analysis is declared on essential

Examination
of the published literature on the rational for the use of Raindrop therapy,
written or published by Gary Young rationalizing the use for Raindrop Therapy,
has implies that the process has a curative effect on scoliosis:
Excerpts verbatim from Essential Oils Desk Reference by G.Young:
·Raindrop
Technique is a powerful, non-invasive tool for assisting the body in correcting
defects in the curvature of the spine. During the years that is has been
practiced, it has resolved numerous cases of scoliosis and kyphosis and
eliminated the need for back surgery for thousands of people.
·Raindrop
Technique originated in the 1980’s from the research of D. Gary Young working
with a Lakota medicine man named Wallace Black Elk. It integrates Vita
Flex and massage, utilizing the poser of essential oils in bringing
the
body into structural and electrical alignment.
·Raindrop
Technique is based on the theory that many types of scoliosis and spinal
misalignments are caused by viruses or bacteria that lie dormant along
the spine. These pathogens create inflammation, which, in turn, contorts
and disfigures the spinal column.
·Raindrop Technique uses a sequence of highly antimicrobial essential oils designed to simultaneously reduce inflammation and kill the responsible viral agents.52
“ Scoliosis”
(discussion on etiology of scoliosis from the writings of Young)
While
a few cases of scoliosis can be attributed to congenital deformities (such
as MS. Cerebral Palsy, Down’s Syndrome, or Marfan’s Syndrome), the vast
majority of scoliosis types are of unknown origin.
Some
medical professionals believe that many cases of scoliosis begin with hard-to-detect
inflammation along the spine cased by latent viruses. Others believe that
it may be due to persistent muscle spasms that have pulled the vertebrae
off the spine out of alignment.
The
Raindrop Technique is one of the most effective therapies for straightening
spines misaligned due to scoliosis.”53
Excerpts from:The Science and Application of Essential Oils, D. Gary Young, ND “ (Video) 1994
Statements
on tape by G. Young
“Raindrop
Therapy is a technique that is beneficial for back problems, scoliosis,
deteriorated disks and compressions”. 54
The
following section provides samples of information found on the World Wide
Web describing Raindrop Therapy.
1.“The
Raindrop Therapy combines the science of aromatherapy with the techniques
of Vita Flex, reflexology, massage, etc, in the application of essential
oils, which are applied on various areas of the body to bring structural
and electrical alignment. Thyme has been scientifically proven to be anti-infections,
antibacterial, and antiviral.
There
is some indication that scoliosis is the result of some viral and or bacterial
activity that has taken place
in the body at some point before the scoliosis began. These essential oils
can easily penetrate the body
and may help kill any virus or bacteria that may be present.”55
2.
“The Raindrop Therapy combines the science of aromatherapy with the
techniques of Vita Flex, reflexology,
massage, etc, in the application of essential oils, which are applied on
various areas of the body to
bring structural and electrical alignment.”56
3.“Raindrop

in the curvature of the spine.
It has resolved numerous cases of scoliosis and eliminated the needs for
back surgery for thousands of
people. Raindrop technique is based on the theory that many types of scoliosis
and spinal misalignments are caused by virus or bacteria that are dormant
along the spine. These pathogens
create inflammation which in turn controls and disfigures the spinal column.
Raindrop Technique uses a sequence of highly anti-microbial essential oils
designed to simultaneously reduce
inflammation and kill the viral agents responsible for it.”57
There
are numerous other references like these on the World Wide Web and a simple
search using the term “Raindrop Therapy” would yield many more.This
information either implies or states, that the use of Raindrop Therapy,
has either a corrective action on scoliosis or that it benefits person,
with scoliosis, or that is somehow otherwise helps to bring the body into
structural or electrical alignment.
Now
let’s turn our attention to what qualified authorities on the topic of
scoliosis, have to say about the etiology of scoliosis.
