Lemon balm Health Benefits
[nutritional values]
The health benefits of lemon balm have been known for many
years in Europe, especially its soothing effects on the
stomach. Lemon balm eases pain and discomfort associated
with digestion, including gas and bloating. It has also been
used traditionally as an herbal medicine for memory-
enhancement, but which is currently more widely used as a
mild sedative and sleep aid.

Lemon balm grows everywhere in the world, though its origin
is Europe. The plant is two feet high with deeply wrinkled dark
green leaves. And, herbal preparations are often made of
these leaves. The leaves contain rosmarinic, caffeic,
protocatechuic acids, phenolic compounds, flavonoids and
these chemicals may contribute the major portion of the
herb's beneficial effects [9, 12].

STUDIES - LEMON BALM BENEFITS

ANTI-OXIDANT ACTIVITIES
Oxidative damage is related to the development of chronic
diseases such as age-related neurodegeneration,
carcinogenesis and atherosclerosis. Antioxidants help lower
the risk of these diseases. Blomhoff R from Universitetet i
Oslo, Norway, suggested that lemon balm is a good source of
antioxidants. [1] In a study, lemon balm at a concentration of
1.5 % w/w was found to increase the antioxidant capacity of a
salad portion by 150 %. [2] On the other hand, lemon balm
oil extracts were found to possesse antioxidant activity, as it
reduced 1,1-diphenyl-2-picryl-hydrazyl (DPPH) in a vitro
testing. [3]

ANTI-CANCER ACTIVITIES
An in-vitro cytotoxicity assay using MTT indicated that lemon
balm oil extracts were very effective against a series of human
cancer cell lines (A549, MCF-7, Caco-2, HL-60, K562) and a
mouse cell line (B16F10). Thus, lemon balm may have benefits
on lowering the risk of certain cancers. [3]

SEDATIVE ACTIVITIES
Melissa officinalis (lemon balm) is contemporaneously used as
a mild sedative and/or calming agent. [7]

Hyperactivity is a very common disorder in children and it has
three major characteristics- Impulsivity, Distraction, and
Hyperactivity. Researcher at Universitat de Barcelona has
proposed to use lemon balm as an aid in the treatment of this
disorder. [5] In a randomized double blind, placebo controlled
trial, German researchers dosed 16 healthy volunteers with a
lozenge containing 4 different herbal preparations (lavender
oil, extracts from hops, lemon balm and oat) or a matching
placebo without any active ingredients. They observed that
the subjects had a better cope with psychological and
emotional stress after taking this lozenge based on their
electrical brain activities. [6]

In a double-blind, placebo-controlled, randomized, balanced
crossover experiment, 18 healthy volunteers received two
separate single doses of a standardized M. officinalis extract
(300 mg, 600 mg) and a placebo, on separate days. The
results showed that the 600-mg dose of Melissa ameliorated
the negative mood effects of the Defined Intensity Stressor
Simulation, with significantly increased self-ratings of
calmness and reduced self-ratings of alertness. In addition, a
significant increase in the speed of mathematical processing,
with no reduction in accuracy, was observed after ingestion of
the 300-mg dose. [7]

COGNITIVE PERFORMANCE
British researchers found that high dose of encapsulated
dried lemon balm leaf improved memory performance and Â
“calmness” significantly. [11, 13]

DYSPEPSIA
German researchers prepared a special supplement containing
extracts from bitter candytuft, matricaria flower, peppermint
leaves, caraway, licorice root and lemon balm for the
treatment of patients with functional dyspepsia. They dosed
120 patients suffered from functional dyspepsia with this
preparation at 4 different dosage patterns. They found that
patients with functional dyspepsia improved dyspeptic
symptoms significantly better than those taking placebo.

CONTENT VARIATION
The analysis of the oil composition of various cultivations of
lemon balms in Poland using GC/MS indicates the variations of
the oil contents from cultivations to cultivations. [8]
