History
The
eucalyptus oil story began in 1788 with the arrival of
the First Fleet and Surgeon-General John White. Within a
few weeks of arriving, White recorded in his diary the
presence of olfactory oil in the eucalyptus; the genus
being named eucalyptus by the French botanist L’Heritier
in the same year. Governor Philip sent a sample to Sir
Joseph Banks. Surgeon-General White distilled a quart of
oil from the "Sydney Peppermint", Eucalyptus
piperita Sm., which was found growing on the shores
of Port Jackson, where Sydney now stands.
When
the oil was tested in England, it was reported to be
"much more efficacious in removing all cholicky
complaints than that of the oil obtained from the well
known English peppermint, being less pungent and more
aromatic". Following this discovery other people
extracted eucalyptus oil, including the pioneer, Dr
Officer in Tasmania, and the pastoralist Charles
Armitage, but none of them exploited it.
Baron Ferdinand von Meuller, the Government Botanist in
Victoria, encouraged Joseph Bosisto, a Victorian
pharmacist, to investigate the essential oils of the
eucalyptus on a commercial basis. Joseph Bosisto was a
Yorkshireman who had qualified as a Pharmacist in Leeds
and London. He arrived in Adelaide in 1848 at the age of
21. In 1851 he moved to Victoria in search of gold, but
instead opened a pharmacy in Richmond, where he built a
laboratory to investigate the chemical and medicinal
properties of Australian plants.
As a
result of the collaboration with von Meuller the
essential oil industry of Australia began in 1852, when
Bosisto commenced operations in a small, rudely
constructed still at Dandenong Creek, Victoria, using
the leaves of a form of E. radiata (then known
as E. amygdalina) which grew profusely in the
district. Bosisto soon built other distilleries at
Emerald, Menzies Creek and Macclesfield.
Sales were to a restricted local market until overseas
interest grew sufficiently for Bosisto to begin exports
to England in 1865. Messrs. Alfred Felton and Frederick
Grimwade saw the possibilities of the trade and their
firm, Felton Grimwade & Co. became the distributors of
Bosisto’s Oil of Eucalyptus which then was the only
distinctively Australian substance in the British
Pharmacopoeia.
To
develop the new industry, Felton, Grimwade, Bosisto and
others formed a new firm, the Eucalyptus Mallee Company
and bought Antwerp Station - a property on the Wimmera
River, near Dimboola, Victoria.
The
low-growing Mallee eucalyptus were particularly suitable
for cropping, but the area was remote and the company
found unexpected difficulties from hungry rabbits and
indolent aboriginal labourers. The enterprise was held
up for some months by delays in the opening of the
railway from Melbourne to Dimboola. By June 1882, 40
pounds of oil had been produced for export to England
and Germany.
In
1885 the Antwerp Company was merged with Bosisto’s
original business and a firm called J. Bosisto and Co.
was formed. The new company was to be solely a
manufacturer with Felton Grimwade and Co. undertaking
distribution and all the necessary bookkeeping and
marketing.
It
is difficult to be certain which was the next species to
be exploited as E. globulus, E. oleosa
and E. cneorifolia were distilled for
commercial purposes in the early 1880’s. Many farmers in
Tasmania were distilling E. globulus at about
the same time. E. cinerea was distilled in the
Goulburn district of NSW between 1880 and 1900. There is
no doubt that considerable interest was evinced in the
exploitation of E. globulus, which ranked only
second to E. amygdalina as a commercial
oil-producing species.
Practically all of these species, with the exception of
E. globulus, have been superseded by those
giving larger yields of oil. The pioneer investigations
of Baker and Smith showed that other species such as
E. polybractea, E. australiana, and E.
dives gave higher yields of oil of equal or better
quality. It is from these latter species that the
present-day Australian eucalyptus oils of commerce are
produced.
The
production of eucalyptus oil in the 1880’s was often
carried out by aboriginals and by erstwhile miners as
the goldfields petered out. It was hard work. The virgin
scrub was cut by hand with slashers and special sickles.
It was collected and carted by wagon to the distillery
where the freshly cut leaves were dumped into vertical
iron stills set into the ground below wagon level for
easy filling. After steam had carried over the volatile
oil the spent leaves were hoisted out by derrick and
dumped on the fire whose rising column of smoke was a
constant landmark.
The
old distilleries were somehow kept going by pieces of
wire, bits of tin, lumps of clay, and the infinite
resourcefulness of the true bush workman, whose
ramshackle buildings were made of hand hewn posts and
roofed with branches of nearby trees.
Sales continued to increase with interest being fostered
through international exhibitions. Between 1854 and 1891
Bosisto’s oil of eucalyptus was exhibited and was
awarded prized in 17 international exhibitions. By the
turn of the century oil was being exported to the United
Kingdom, Germany, USA, Canada, South Africa, India,
China, New Zealand and several countries in the Far
East.
Sales were brisk following a lively promotion campaign.
Bosisto’s produced an elaborate new label and a thousand
circulars attesting to the powerful properties of oil of
eucalyptus for "arts, manufactures, medicine and
sanitary purposes" were distributed throughout the
colonies and in Europe. In addition to the oil itself,
Bosisto produced asthma cigarettes of eucalyptus
globules which soon won some renown. These could be
bought with or without tobacco. He also had a profitable
line in Syrup of Red Gum for bowel complaints which he
claimed was very soothing.
By
1900 Australia’s eucalyptus oil industry was well
established and able to supply the world market with
substantial quantities of various types of high grade
oils.
However, it should be pointed out that from the very
beginning oil production has been a very primitive
business. Even today in a few areas the distillation of
the foliage is still carried out in primitive stills set
here and there in the mountains.
That
the industry could develop and prosper until the Second
World War is due greatly to one factor. Around the turn
of the century the once rich gold fields in Victoria and
New South Wales - the present producing regions of
eucalyptus oils - started to run out and become
unprofitable.
The
gold miners found themselves without work. They had
become used to the rough but free and independent life
in the bush and consequently joined the eucalyptus
distillers rather than seek employment in cities and
towns. Things changed with World War II. The old class
of distillers was gradually dying out and the younger
generation would no longer accept the low wages and poor
living conditions that had prevailed.
By
about 1950 the cost of producing eucalyptus oil in
Australia had increased so much that the oil could no
longer compete against Spanish and Portuguese oils and
Australia lost its leading position in the eucalyptus
field.
Labour cost, however, was not the only cause of the
decline. After the Second World War there was a strong
demand for Australian wheat and this induced drastic
destruction of stands of high quality eucalyptus
species. Improved wheat strains and modern farming
machinery allowed wheat to be grown successfully on land
formerly suited only for eucalyptus. The class-conscious
prosperous Australian wheat farmers have always been
inclined to look upon oil production as a low grade
occupation. Wheat growing appeared to be more profitable
than eucalyptus oil production.
Australia dominated the world eucalyptus oil market for
over 80 years. Regretfully Australia’s market share then
declined to the point where Australia became a net
importer of eucalyptus oil. Happily this trend is now
being reversed, at least for medicinal oils. Advances in
science and technology have been combined to modernise
the industry.
By
introducing mechanical harvesting and new distillation
equipment the cost of production has been reduced
greatly. This together with the natural advantages
Australia has in having stands of eucalypts with high
quality pharmaceutical oils has given the industry an
opportunity to again become the dominant supplier in
world trade. |
