Jasmine (Jasminum) is a genus of shrubs and vines with about 200 species, native to tropical and warm temperate regions of the Old World. The majority of species grow as climbers on other plants or on structures. Jasmine flowers are white in most species, but with some species being yellow flowered.
Jasmine is frequently used in aromatherapy. Jasmine aroma appears to have sedating and relaxing properties. Jasmine is a common fragrance used in perfumes.
Jasmine Tea
Jasmine tea is sometimes made from green or pouchong (Chinese
green) tea leaves that are scented with jasmine flowers. The jasmine
flowers are harvested during the day and stored in a cool place until
night. During the night, the flowers bloom with full fragrance. The
flowers are layered over the tea leaves during the scenting process. The
quality of jasmine tea is determined by the quality of green tea used as
its base and the effectiveness of the scenting.
There are many herbal
teas available, and jasmine tea is a good option. However, it is a good
idea to alternate different herbal teas in order to get a number of
beneficial substances from different teas. It has been proposed that
jasmine tea has anticancer benefits. This may be true, but many herbs have
anticancer benefits and there is no reason to suspect jasmine tea is any
more beneficial than other herbal teas.
Jasmine Research Update
Chemopreventive efficacy and anti-lipid peroxidative potential of
Jasminum grandiflorum Linn. - jasmine - on
7,12-dimethylbenz(a)anthracene-induced rat mammary carcinogenesis.
Fundam Clin Pharmacol. 2005 Dec;19(6):687-93.
The aim of this study was to investigate the chemopreventive efficacy
and anti-lipid peroxidative potential of jasmine on
7,12-dimethylbenz(a)anthracene (DMBA)-induced rat mammary carcinogenesis.
The results of this study clearly indicate that jasmine has potent
chemopreventive efficacy in experimental mammary carcinogenesis and
further studies are warranted to isolate and characterize the bioactive
principle from jasmine
Effectiveness of aroma on work efficiency:
lavender aroma during recesses prevents deterioration of work
performance.
Chem Senses. 2005 Oct;30(8):683-91.
The present study investigated whether exposure to aromas during recess
periods affects work performance. Subjects comprised 36 healthy male
students (mean age, 24 years) who were randomly divided into
three groups: (1) control group, not exposed to aroma during recesses; (2)
jasmine group, exposed to jasmine aroma during recesses; and (3) lavender
group, exposed to lavender aroma during recesses. All participants
completed five work sessions performing a task requiring concentration on
a computer monitor, with each session lasting 60 min. Recess periods of 30
min were provided between each session. To clarify the time at which work
concentration was lowest, work performance for the control group was
analyzed. Concentration was lowest in the afternoon period, where
afternoon drowsiness is strongest. Comparison of the three groups for this
time period indicated significantly higher concentration levels for the
lavender group than for the control group. No such effect was noted for
the jasmine group. Although lavender is a sedative-type aroma, use during
recess periods after accumulation of fatigue seems to prevent
deterioration of performance in subsequent work sessions.
Sedative effects of the jasmine tea odor and
(R)-(-)-linalool, one of its major odor components, on autonomic nerve
activity and mood states.

We investigated the effects of the odor of jasmine tea on autonomic
nerve activity and mood states in a total of 24 healthy volunteers. We
used the odor of jasmine tea at the lowest concentration that could be
detected by each subject but that did not elicit any psychological
effects. R-R intervals and the POMS test were measured before and after
inhalation of the odors for 5 min. Both jasmine tea and lavender odors at
perceived similar intensity caused significant decreases in heart rate and
significant increases in spectral integrated values at high-frequency
component in comparison with the control. In the POMS tests, these odors
produced calm and vigorous mood states. We also examined the effects of
(R)-(-)-linalool, one of its major odor components, at the same
concentration as in the tea, and (S)-(+)-linalool. Only (R)-(-)-linalool
elicited a significant decrease in heart rate and an increase
in high-frequency component in comparison with the controls, and produced
calm and vigorous mood states. Thus, the low intensity of jasmine tea odor
has sedative effects on both autonomic nerve activity and mood states, and
(R)-(-)-linalool, one of its components, can mimic these effects.
Jasmine Tea Questions
Q. Is it okay to drink jasmine
tea daily?
A. Jasmine tea does have good antioxidants, but I
prefer to alternate different tea. Drinking jasmine tea 2 or 3 times a
week would be fine, and the rest of the time you can alternate drinking a
number of other herbal teas available in health food stores.
Q. I'm a freelance writer. I've been asked to write
a short piece on Jasmine Tea as a potential mood lifter for a magazine.
I've written for such magazines as Alternative Medicine, Better Nutrition,
Urban Male etc. I've just started my research and discovered recent
studies suggest jasmine tea produces calm and vigorous mood states. Would
you be so kind to offer a quote for my article? If so, please provide a
written response to the following questions?
1. How often do you recommend drinking jasmine tea? Every day, 1-3 times a
week, once a week when, how much?
2. Do you find jasmine tea effective in calming mood? Thank you for your
time. I look forward to hearing from you.
A. I prefer individuals vary the teas they drink in order to obtain
beneficial substances from a number of herbal teas as opposed to ingesting
the same substances every day. As such, drinking jasmine tea once or twice
a week would be quite acceptable. Jasmine tea has a mild calming effect,
but - based on the jasmine tea brands I have tried - it is not as potent
as some other teas such as passionflower.
