Eucalyptus,
(genus Eucalyptus), large genus of more than
660 species of shrubs and tall trees of the myrtle family
(Myrtaceae), native to Australia, Tasmania, and nearby islands. In
Australia the eucalypti are commonly known as gum trees or stringybark trees.
Many species are cultivated widely throughout the temperate regions
of the world as shade trees or in forestry plantations. Economically,
eucalyptus trees constitute one of the most valuable groups within
the order Myrtales.
The eucalypti grow rapidly, and
many species attain great height. The giant gum tree, or mountain ash
(Eucalyptus regnans), of Victoria and Tasmania, is one of the largest species
and attains a height of about 90 metres (300 feet) and a circumference of 7.5
metres (24.5 feet). Many species continually shed the dead outermost layer
of bark in flakes or ribbons, whereas certain other species have thick
textured bark. The leaves are leathery and often hang obliquely or
vertically; most species are evergreen. The flower petals cohere
to form a cap when the flower expands. The capsule fruit is
surrounded by a woody cup-shaped receptacle and contains numerous minute seeds.
Possibly the largest fruits—from 5 to 6 cm (2 to 2.5 inches) in diameter—are
borne by mottlecah, or silverleaf eucalyptus (E. macrocarpa).
The leaf glands of many
species, especially black peppermint tree (E. salicifolia)
and Tasmanian bluegum (E. globulus), contain a volatile aromatic oil known
as eucalyptus oil. Its chief use is medical, and
it constitutes an active ingredient in expectorants and inhalants.
Tasmanian bluegum, northern gray ironbark (E. siderophloia), and other
species yield what is known as Botany Bay kino, an astringent dark
reddish resin, obtained in a semifluid state from incisions made in the
tree trunk.
Eucalyptus Oil in Pharma
As an ingredient, the
cineole-based oil is used as component
in pharmaceutical preparations to relieve the symptoms of influenza
and colds, in products like cough sweets, lozenges, ointments and inhalants.
Inhaled eucalyptus oil vapor may be a decongestant.
Essential oil obtained by steam
distillation and rectification from the fresh leaves or the fresh terminal
branchlets of various species of Eucalyptus rich in 1,8-cineole. The species
mainly used are Eucalyptus globulus Labill, Eucalyptus polybractea
and Eucalyptus smithii. Eucalyptus oil BP has cineole of over 70%
and is used as a component in pharmaceutical preparations of medicines such as
colds and coughs.
The cooling scent
of Eucalyptus Essential Oil is used in aromatherapy to relieve mental
exhaustion and rejuvenate the human spirit. It boosts circulation to the brain
and reduces harmful surface and airborne pathogens upon contact.
Essence of Eucalyptus Oil
As A Perfume Ingredient, adding
eucalyptus to a fragrance can be a very tricky endeavor because it is so potent
that it can easily dominate any scented formulation and deteriorate into ‘an
unwanted hint-of-mothball’ aspect.
Typically used as a minty, woody,
citrusy middle note in fragrances, eucalyptus is known for its fresh clean
aroma and is often found in soaps, detergents, mouthwashes and lotions as well
as perfume. It adds an airiness to any fragrance with its fresh, green,
camphor-like and lemony aspects.
