ABSTRACT
Objective: The purpose of this study was to explore the effect of aromatherapy on menstrual cramps and
symptoms of dysmenorrhea.
Design: The study was a randomized placebo-controlled trial.
Subjects: The subjects were 67 female college students who rated their menstrual cramps to be greater than
6 on a 10-point visual analogue scale, who had no systemic or reproductive diseases, and who did not use con-
traceptive drugs.
Intervention: Subjects were randomized into three groups: (1) an experimental group (n 25) who received
aromatherapy, (2) a placebo group (n 20), and (3) a control group (n 22). Aromatherapy was applied top-
ically to the experimental group in the form of an abdominal massage using two drops of lavender (Lavandula
officinalis), one drop of clary sage (Salvia sclarea), and one drop of rose (Rosa centifolia) in 5 cc of almond
oil. The placebo group received the same treatment but with almond oil only, and the control group received
no treatment.
Outcome measures: The menstrual cramps levels was assessed using a visual analogue scale and severity
of dysmenorrhea was measured with a verbal multidimensional scoring system.
Results: The menstrual cramps were significantly lowered in the aromatherapy group than in the other two
groups at both post-test time points (first and second day of menstruation after treatment). From the multiple
regression aromatherapy was found to be associated with the changes in menstrual cramp levels (first day:
Beta 2.48, 95% CI: 3.68 to 1.29, p 0.001; second day: Beta 1.97, 95% CI: 3.66 to 0.29,
p 0.02 and the severity of dysmenorrhea (first day: Beta 0.31, 95% CI: 0.05 to 0.57, p 0.02; second day:
Beta 0.33, 95% CI: 0.10 to 0.56, p 0.006) than that found in the other two groups.
Conclusions: These findings suggest that aromatherapy using topically applied lavender, clary sage, and rose
is effective in decreasing the severity of menstrual cramps. Aromatherapy can be offered as part of the nurs-
ing care to women experiencing menstrual cramps or dysmenorrhea.

INTRODUCTION
D
ysmenorrhea is defined as painful menstruation in-
volving low abdominal pains (menstrual cramps),
which may be accompanied by other symptoms such as nau-
sea and fatigue. Menstrual cramps caused by dysmenorrhea
are a common problem. Some studies suggest that 50–93%
of women experience menstrual cramps caused by dysmen-
orrhea, and that 10–26% of women experience severe pain.
In a recent study in Korea, 83% of college women com-
plained of menstrual cramps, 18% rating their pain as very
severe.
1
In the most severe cases, the pain was rated 7.9 on
a 10-point visual analogue scale (VAS). However, despite
frequent occurrence and severity, menstrual cramps are not
acknowledged as a serious problem or one requiring nurs-
ing intervention. However, Milsom et al.
2
showed that the
intra-uterine pressure (IUP) of a patient with dysmenorrhea
was 55.3 3.8 mmHg in the relaxation phase and 175.0
6.1 mmHg in the contraction phase, and that the IUP dur-
ing contraction is greater than in labor.
1
Dysmenorrhea is usually treated with drugs, such as anal-
gesics, sedatives, antispasmodics, prostaglandin inhibitors,
uterine contraction inhibitors, nonsteroidal anti-inflammatory
drugs, vasopressin antagonists, and medication to stop ovu-
lation.
3
In a review article, Dawood
3
suggested that none of
these therapies are particularly effective but some may lead
to dependence or affect cognitive function. Bed rest, local heat
therapy, surgical intervention, and psychotherapy have also
been used.
3
In a 1999 survey, Han and Hur
1
found that the
most common methods to cope with menstrual cramps were
“endurance” and medication. Campbell and McGrath
4
found
that 70% of women with dysmenorrhea use medication. How-
ever, Chambers et al.
5
noted that the medication might not be
effective if not used regularly. Many studies suggest that men-
strual cramps and dysmenorrhea are not managed efficiently
despite their high occurrence and severity.
A variety of alternative methods have been used to treat
menstrual cramps. Some experimental studies have found
alternative methods such as acupuncture
6
and transcuta-
neous electrical nerve stimulation (TENS)
7
to be fairly ef-
fective (e.g., 50% reduction in pain). Kotani et al.
8
found
that the herbal medicine Toki-shakuyaku-san [Japanese an-
gelica root (Angelicae radix), peony root (Paeoniae radix),
Poria (Hoelen spp.), Chinese atractylodes rhizome (Atracty-
lodis lanceae rhizoma), Oriental water plantian rhizome
(Alismatis rhizome), Cnidium (cnidii rhizoma)] was more ef-
fective than placebo in treating primary dysmenorrhea. At-
tempting to cure idiopathic menstrual pain, Kim* used a
placebo in the form of a vitamin pill. Dawood and Ramos
9
suggested that concurrent use of TENS and ibuprofen might
be an effective treatment, and Harel et al.
10
used supple-
ments such as omega-3 fatty acids. TENS and ibuprofen to-
gether appear to be the most effective treatment for men-
strual cramps. Vance et al.
11
tried microwave diathermy, and
Kim et al.
12
tried biofeedback. However, many of these
treatments cannot be prescribed by nurses, and many con-
ventional drugs have side effects or their main effects do not
last long. Because dysmenorrhea is so common and has been
inadequately addressed, it is important to find an effective
method that can be easily used.
Aromatherapy is the therapeutic use of essential oils from
plants. Essential oils can be absorbed into the body via the
skin or the olfactory system. Aromatherapy is thought to be
particularly efficacious against menstrual cramps or dys-
menorrhea.
13–15
In some countries aromatherapy products
are sold and aromatherapy is used as a major complemen-
tary “caring” therapy.
16
Aromatherapy is perceived to be a
safe therapy.
17
Essential oils have been used for several hun-
dred years and are used regularly today by the public for
stress-management and for minor ailments.
18
However, the therapeutic effects of aromatherapy are not
well supported by clinical studies.
19
Keville and Green
20
sug-
gested that essential oils should be used for several days be-
fore dysmenorrhea or menstrual cramps are expected. They
recommend that the essential oils of chamomile (Chamomelum
nobile), clary sage (Salvia sclarea), lavender (Lavandula an-
gustifolia), marjoram (Origanum majorana), melissa (Melissa
officinalis), and geranium (Pelargonium graveolens) help in
treating menstrual cramps. Tisserand
15
suggested clary sage,
lavender, rose (Rosa centifolia), marjoram, geranium, and gin-
ger (Rhizoma zingiberis recens) as effective in treating dys-
menorrhea. Dye
13
suggested clary sage, chamomile, geranium,
and rose, while Baker
21
suggested geranium, Roman
chamomile, rosemary, lavender, clary sage, and sage.
The essential oil of lavender is thought to be an adreno-
cortical stimulant that stimulates menstruation and circula-
tion and has anticonvulsive properties. Lavabre
14
suggested
that lavender is also useful as a sedative and to alleviate
pain. Tisserand
15
suggested that clary sage has functions
similar to estrogen, such as normalizing the menstrual cy-
cle, promoting menstruation, and strengthening the uterus.
Tisserand
15
also suggested that rose has a great affinity for
the uterus and helps regulate the menstrual cycle and reduce
excessive bleeding. In this study, we hypothesized that ap-
plying these three essential oils together would provide a
synergistic blend that would have the highest chance of suc-
cess in treating the pain of menstrual cramps.
Different methods are used to deliver aromatherapy, such
as diffusers, baths, massage, and compresses. Massage is be-
lieved to be an effective way to improve blood and lymph
circulation and to reduce stress and ease stiff muscles. For
massage, the essential oil is diluted in a cold-pressed veg-
etable oil, a popular choice being sweet almond oil.
13,14,20
Massage appears to be a suitable method to deliver aro-
matherapy to treat menstrual cramps of dysmenorrhea.
The purpose of this study was to investigate whether the
combination of lavender, clary sage, and rose applied topically
alleviates menstrual cramps. If the results were positive, this

method of aromatherapy might be adopted as a nursing inter-
vention for patients with painful menstrual cramps.
MATERIALS AND METHODS
Design
The study consisted of a double-blind, three-group ex-
perimental pre-test/post-test design. Fifty-seven (57) partic-
ipants were randomly assigned to one of three groups. The
experimental group received aromatherapy in almond oil
with massage, the placebo group received treatment with al-
mond oil only and massage, and the control group received
no treatment.
The levels of dysmenorrhea and general and menstrual
characteristics were measured before the study began. After
the intervention, the levels of dysmenorrhea were measured
for each group on the first and second days of menstruation.
Subjects were told there were no side effects or contraindi-
cations to the treatment they were about to receive, but that,
in rare instances, skin irritation could occur. The study re-
ceived institutional approval from the Human Investigation
Ethics Committee and administrative approval from the Hu-
man Subjects Review Board of Wonkwang University Hos-
pital and School of Medicine before we approached the sub-
jects and obtained written consent from them.
Participants
The participants were college women enrolled in uni-
versities in Korea. A previous survey had identified 85
women who experienced dysmenorrhea. The selection cri-
teria were: (1) pain of menstrual cramps greater than 6
points on the 10-point VAS (a line calibrated from 0–10,
with 0 representing “no pain at all” and 10 representing
“pain as bad as it could be”); (2) no systemic disease or
disease of the genital organs; and (3) no use of contra-
ceptives. Participants who failed to meet all of these cri-
teria were excluded from the study. Patients with myoma
or fibrocystadenoma were also excluded from the study.
Of the 85 subjects who were originally screened, 67 en-
tered the initial phase of the study.
The experimental group (n 25; mean age, 20.6 1.27
years) received aromatherapy in almond oil with massage.
The placebo group (n 20; mean age, 20.9 1.93) re-
ceived treatment with almond oil only and massage, and the
control group (n 22; mean age, 20.5 0.51) received no
treatment. To randomize the study, each participant drew a
piece of paper with either A, B, or C written on it from a
closed box. When a participant drew A, she joined the ex-
perimental group; B, the placebo group; and C, the control
group. In discussing the nature of aromatherapy and the ex-
perimental procedures, the subjects were informed that they
would receive one of two types of aromatherapy, both of
which had the potential to relieve menstrual cramps. Sub-
jects were blinded as to whether they were receiving real or
sham aromatherapy, as were the clinical observers assess-
ing the endpoints. Four assistants contacted the subjects and
checked their responses.
Intervention
The experimental group received aromatherapy in the treat-
ment room every day beginning one week before the start of
menstruation and continuing until the first day of menstrua-
tion. The experimental and placebo groups received 15 min-
utes of aromatherapy or placebo, respectively. The aro-
matherapy was provided in the form of abdominal massage
with essential oils of lavender, clary sage, and rose in a 2:1:1
ratio, diluted in almond oil at a final concentration of 3%. The
treatment room for abdominal massage was isolated and
equipped with beds warmed by heating pads. Clients were re-
quested to lie on the bed and rest after the abdominal mas-
sage. The clients in the placebo group had the same treatment
with almond oil only. Each treatment lasted about 15 minutes
for both groups. No treatment was provided to the control
group, who continued their daily routine.
Each subject received a 15-minute abdominal massage
beginning with effleurage strokes in the shape of a flat di-
amond, working clockwise with a pressure of 4 on a scale
of 0–10, where 0 is no pressure and 10 is crushing pressure.
The masseur’s left hand was placed on the right hand and
both hands were placed on the right lower abdomen. The
stroke went to the ribs and then across the abdomen to the
left lower abdomen. This was followed by gentle kneading
at the left and right of the waist and then stroking across the
abdomen. Following this, the effleurage flat diamond stroke
began again. The strokes were slow, smooth, and continu-
ous. A cushion was placed under the subject’s knees to keep
the abdomen relaxed.
Data such as the severity of menstrual cramps and the
general and menstrual characteristics were collected from
all participants before the experiment and designated as pre-
test data. Data on the severity of menstrual cramps were col-
lected on the first and second days of menstruation after the
experimental treatment and designated as post-test data.
Measurement of menstrual cramps
The intensity of menstrual cramps was measured with a
10-point VAS, indicated by pointing to the appropriate value
on a 10-cm horizontal ruler. The intensity of pain was rated
to the first decimal place in centimeters. Higher scores re-
flected a greater severity of menstrual cramps.
Severity of dysmenorrhea
To measure the effect of dysmenorrhea on daily life, a
verbal multidimensional scoring system was applied as
used by Andersch and Milsom
22
and Sundell et al.
23
The
system uses four grades to indicate the extent to which
dysmenorrhea influences daily life. According to this scor-
ing system, mild dysmenorrhea is defined as menstruation

that is painful but seldom inhibits the woman’s normal ac-
tivity and analgesics are seldom needed. Moderate dys-
menorrhea affects daily activities and requires analgesics,
but missing work or school is unusual. Severe dysmenor-
rhea clearly inhibits daily activity, is managed poorly by
analgesics, and has associated somatic symptoms such as
headache, tiredness, nausea, vomiting, or diarrhea. Symp-
toms were scored from 1 to 4 (1 none; 2 mild; 3 moder-
ate; 4 severe), according to the intensity experienced by
the subjects.
Data analysis
The data were analyzed using SigmaStat (Systat Software,
Richmond, CA) and SPSS software (SPSS, Chicago, IL).
Since the data were not normally distributed, the results are
presented as medians and interquartile ranges (IQRs). All out-
comes were compared using the nonparametric Mann-Whit-
ney rank test between groups and the Wilcoxon signed-rank
test across treatment times for each group.
Multiple regression analyses were used to estimate the ef-
fects and the validity of the hypothesis. We divided the analy-
ses into two parts, analyzing the first- and second-day results
with respect to baseline. In each of these analyses, the change
score (postintervention minus preintervention) was regressed
on the baseline score with two dummy-variable indicators:
one indicator was 1 for the placebo group and 0 otherwise,
and the other was 1 for the aromatherapy group and 0 other-
wise. The coefficients of these indicators therefore represent
placebo versus control and aromatherapy versus control com-
parisons. This procedure was performed separately for the
first- and second-day data.
The severity of dysmenorrhea in each woman was di-
chotomized into either 1, representing improvement (mean-
ing a strictly better postintervention score), or 0, represent-
ing no change or a lower postintervention score than
preintervention score. We then applied generalized multiple
linear regression modeling to this outcome.
RESULTS
The participants reported no side effects from the treat-
ment. The demographic characteristics of the participants
are listed in Table 1.

Table 2 lists the medians and IQRs for the levels of men-
strual cramps in the groups measured at three time points. The
severity was significantly lower in the aromatherapy group
than in the other two groups at both postintervention time
points (first and second days of menstruation after treatment).
Regression analyses were also applied to the changes in
severity at each day (postintervention minus preintervention)
using the baseline value, two indicators for aromatherapy, and
placebo compared to control. Aromatherapy was most strongly
associated with change in severity (Beta 2.48, 95% CI:
3.68 to 1.29, p 0.001), followed by the baseline value
of level of menstrual cramps (Beta 0.62, 95% CI: 0.99
to – 0.26, P 0.001), with the weakest association being with
placebo (Beta 0.42, 95% CI: 0.83 to 1.67, p 0.51) com-
pared to control for the first day. The trend was the same for
the second day. Aromatherapy was most strongly associated
with change in severity (Beta 1.97, 95% CI: 3.66 to
0.29, p 0.02), the baseline value of level of menstrual
cramps (Beta 0.52, 95% CI: – 1.04 to – 0.003, p 0.05),
and placebo (with the weakest association being with placebo
(Beta 0.27, 95% CI: 1.49 to 2.04, p 0.76) compared to
the control group).
Table 3 lists the severity of dysmenorrhea. We estimated
and tested the trends by applying multiple linear regression
modeling to the dichotomized severity of dysmenorrhea and
the dummy-variable indicators. The results demonstrated
that aromatherapy was associated with the change in sever-
ity (Beta 0.31, 95% CI: 0.05 to 0.57, p 0.02), the base-
line value of severity (Beta 0.21, 95% CI: 0.04 to 0.37,
p 0.02), and not for placebo (Beta 0.003, 95% CI:
–0.29 to 0.28, p 0.98) compared to controls for the first
day. The trend was the same for the second day. Aro-
matherapy was associated with the severity change (Beta
0.33, 95% CI: 0.10 to 0.56, p 0.006), the baseline value
of severity (Beta 0.33, 95% CI: 0.18 to 0.48, p 0.001),
and not for placebo (Beta 0.15, 95% CI: 0.40 to 0.10,
p 0.23) compared to controls.
DISCUSSION
One of the main goals of nursing is to enhance a patient’s
quality of life, which might include providing proper nursing
care for patients with menstrual cramps or dysmenorrhea. Be-
cause menstrual cramps and dysmenorrhea are personal top-
ics, women may suffer from these symptoms without seek-
ing help from a health care professional.
4,24,25
In some
extreme cases, the internal pressure from the uterine contrac-
tion during menstruation may be higher than that of labor.
22
The participants reported a serious level of discomfort before
the experimental treatment, as shown by the mean rating of
menstrual cramps of 7.18 1.37 on the 10-point VAS.
According to Sundell et al.
23
and Han and Hur,
1
greater
menstrual flow is associated with more severe pain. The
pretest data showed no differences in menstrual flow be-
tween the three groups. Han and Hur
1
showed that variables
such as age at menarche and the interval and duration of
menstruation are not related to menstrual cramps. These
variables did not differ significantly between groups and the
age at menarche differed by only 0.3 of a year.
In the experimental group, the abdominal massage was
given using 3% essential oils consisting of lavender, clary
sage, and rose (2:1:1 ratio) diluted in almond oil. Massage
is thought to enhance essential oil penetration into the skin.
The VAS was used to measure the effect of the experi-
mental treatment on menstrual cramps. Our results showed
that the levels of the menstrual cramps were reduced in the
experimental group more significantly compared with those
of other groups. In the experimental group, the menstrual
cramps on the first menstruation day decreased from 7.40

to 4.26 after aromatherapy. The change of the severity of
dysmenorrhea was significantly associated with aromather-
apy, suggesting that aromatherapy has an alleviating effect
on the severity of dysmenorrhea experienced during the first
few days of menstruation.
When the results of the study are compared with the out-
come of relaxation treatment to alleviate menstrual cramps via
biofeedback training, the reduction to 5.3 of menstrual treat-
ment is higher than that of bio-feedback.
12
In a study to ver-
ify the effects of herbal medicine on menstrual cramps, Kotani
et al.
8
reported a decrease in cramp severity from 6.2 to 4.4 on
the 10-point VAS scale after one menstrual cycle and to 3.2
after the second cycle. The effect of aromatherapy treatment
in our study produced a similar effect to those of the herbal
medicine TSS and TENS, which decreases the incidence of
sharp pains by 50%.
7
Although no other clinical studies have
been published on the effect of aromatherapy on menstrual
cramps, our data appear to support claims that aromatherapy
has beneficial effects in treating menstrual discomfort.
Menstrual cramps and dysmenorrhea are believed to be
“anemic pains” caused by reduced blood flow because of uter-
ine hyperactivity. The pain is associated with increased
prostaglandin and vasopressin production,
26,27
which causes
contraction and infarction of the endometrium. Menstrual
cramps and dysmenorrhea can occur when the menstrual flow
is constricted. Menstrual cramps are thought to be relieved by
increased blood circulation and antispasmodic and hormone-
regulatory drugs. The experimental group showed a signifi-
cant association with the changes in the scores for menstrual
cramps compared to the other groups after the intervention,
suggesting that aromatherapy has a beneficial effect on the
cramps experienced during the first few days of menstruation.
The experimental group showed significant improvement
of dysmenorrhea as assessed by the verbal multidimensional
scoring system. The data suggest that topically applied di-
luted essential oils of lavender, clary sage, and rose are ef-
fective in alleviating the pain of menstrual cramps. Tradi-
tionally, lavender has been used as an analgesic, sedative,
and anticonvulsant; clary sage as an anticonvulsant, regula-
tor of menstruation, and to support the actions of estrogen;
and rose to alleviate uterine problems.
28
There is a limitation associated with the blinding used in
this study. It is generally preferable to have participants ran-
domized by a third party (often the project biostatistician or
someone otherwise not associated with the study) using a
computer-generated random-number procedure. Hence, the
blinding procedure used in this study (i.e., of drawing slips
from a box) is considered inadequate.
In conclusion, this research suggests that aromatherapy
has a significant effect on menstrual cramps or dysmenor-
rhea. Because there were no side effects, aromatherapy can
be regarded as a safe, simple, cost-effective, and viable
method of nursing care suitable for all patients. However,
nurses should first undertake clinical training in aromather-
apy before incorporating it into their practice.
