The laurel tree
is a small unimpressive shrub or tree, originating in the eastern Mediterranean
countries. The evergreen tree reaches maturity after five years and yields
about 5 kg of leaves per season, which in turn gives about 50-70 g of essential
oil.
Bay laurel was
used to fashion the laurel wreath of ancient Greece, a symbol of highest
status. A wreath of bay laurels was given as the prize at the Pythian Games
because the games were in honor of Apollo, and the laurel was one of his
symbols.
The symbolism
carried over to Roman culture, which held the laurel as a symbol of victory. It
is also the source of the word’s baccalaureate and poet laureate, as well as
the expressions "assume the laurel" and "resting on one's
laurels". Ovid tells the story in the Metamorphose that laurel tree was
first formed when the nymph Daphne was changed into a laurel tree because of
Apollo's pursuit of her. Daphne is the Greek name for the tree.
The essential
oil is extracted from the bay laurel leaves by steam distillation. The oil has
herbaceous and spicy scent and comes in numerous variations.
For example, the oil produced in North Africa has an aroma reminiscent of eucalyptus due to the high content of cineol while the oil produced in Italy or France has a lower cineol content resulting in an aroma most people associate with the laurel leaves used in cooking.

TOXICOLOGICAL INFORMATION
Safety
summary
·
Hazards: Potentially carcinogenic, based on methyl eugenol content;
essential oils high in 1,8-cineole can cause CNS and breathing problems in
young children; skin sensitization (low risk); mucous membrane irritation (low
risk).
·
Contradiction: Due to the
presence of high concentration of eugenol, this oil can cause irritations in
the skin and mucus membrane. It should be avoided during pregnancy. May cause
skin irritation in some individuals; a skin test is recommended prior to use.
Contact with eyes should be avoided.
Cautions: (dermal) Hypersensitive, diseased or damaged skin, children under
2 years of age. Some laurel leaf oils may cause skin sensitization.
Maximum adult
daily oral dose 18 mg
Maximum
dermal use level
·
EU 0.005%
·
IFRA 0.01%
Safety advice:
Recommended
dermal maximum of 0.5% and an oral maximum of 18 mg, based on 3.8% methyl
eugenol content with dermal and oral limits of 0.02% and 0.01 mg/kg.
Regulatory guidelines:
IFRA recommends
that the maximum concentration of methyl eugenol for leave-on products such as
body lotion should be 0.0004%. The equivalent SCCNFP maximum is 0.0002%.
Organ-specific
effects
·
Adverse skin reactions: In a 48-hour occlusive patch test on 50 Italian volunteers,
undiluted laurel leaf oil produced no adverse reactions. Similarly tested at
1%, it produced no reactions in 380 eczema patients (Meneghini et al 1971).
Undiluted laurel leaf oil was moderately irritating to rabbits, but was not
irritating to mice or pigs. Tested at 2% on 25 volunteers it was not
irritating, nor was it irritating when re-tested at 10%. A second sample of
laurel leaf oil was not irritating when tested at 10% on two separate panels of
volunteers. Laurel leaf oil was non-phototoxic in hairless mice and swine.
Systemic
effects
·
Acute toxicity: Laurel leaf oil acute oral LD50 in rats 3.95 g/kg;
acute dermal LD50 in rabbits >5 g/kg. 1,8- Cineole has been reported to
cause serious poisoning in young children when accidentally instilled into the
nose.
·
Antioxidant/pro-oxidant
activity: A laurel leaf oil showed moderate
antioxidant activity in scavenging DPPH radicals and inhibiting lipid
peroxidation.
·
Carcinogenic/anticarcinogenic
potential: Laurel leaf oil containing 2.5% methyl
eugenol was active against human melanoma, renal cell adenocarcinoma, and human
chronic myelogenous leukemia cell lines in vitro. Methyl eugenol is a rodent
carcinogen if exposure is sufficiently high.
