Results of Oil Research - January 1997

Late last year I started testing
some oil samples that had been supplied by Peter Thompson (Qld),
John Snowden (WA) and Greg Barowski (VIC) to assist us with research
into the differences in arthritis treatment in emu oil.
In the last 12 months we have tested about 40 samples and
have obtained some interesting results.
This research
has primarily involved emus sourced in Queensland and much encouragement
from Peter Thompson, John and Fay Spencer, and it would also not
have been possible without assistance from Craig Davis of Queensland
Department of Primary Industries, Desley Butters and Athol Turner.
Whilst this work would not have been possible without their
help, there is no way that the challenges confronting the research
needs of emu oil will be satisfied if we continue to rely on this
level of funding and assistance.
I therefore
applaud these people for agreeing to let me indicate the results
form what I have been doing.
Following therefore is an overview of what we have been trying
to do and a summary of results to date.
It is too early to draw any conclusions other than to state
that there is a very large variation in the anti-inflammatory potency
of emu oil samples that I have tested to date.
My colleague in the Hospital, Dr. Sherree Cross, and Dr.
Snowden (Ag. West, S Perth) will be looking at the wound healing
potential of some of these oils to see if this correlates with the
anti-inflammatory activity.
Further
research is needed and I am extremely please to know that Peter
will be setting up several pens for different nutritional regimes
so that we can follow these through in a few months time to see
what, if any, variation we find in the medicinal potential of the
oils.
The major
objective of the research has been to find a source of oil with
a consistent high level of biological activity that we can use as
a benchmark for further testing and for development of a chemical
test that does not require the use of rats.
Dependence on rats for testing for beneficial medicinal properties
is not only expensive and time consuming but likely to be limited
due to the pressures associated with animal rights pressure groups.
Having
had the opportunity to test samples where we know the whole history
of the birds that the fat has been supplied form has been an essential
prerequisite for these trials.
Also knowledge that we will be able to source additional
birds form the same supplier when we locate the ideal outcome has
been equally as important.
Results
of this research have revealed a large variation different samples.
Based on our scoring system which provides an overall anti-arthritis
score of from 1 to 100, we have obtained results ranging from 0
to 81.
Whilst
it is too early to draw conclusions as to what conditions or prerequisites
provide the best oil in terms of biological activity (particularly
for treating arthritis) we have been rather dismayed by the large
variation in samples.
The samples
tested have included differences based on genetic background (ie
Queensland of West Australian origin), nutritional regime (ie several
proprietary mixes with and without access to pasture as well as
straight native vegetation);
Sex;
Age;
Native
of farmed;
Gut
versus back fat.
We have
also tested oils which are commercially available in the UK, USA,
Canada, and sourced from five Australian States.
In concluding
this article I would like to make a special appeal for the Industry
as a whole to get behind this research.
If we are unable to get national funding for the work that
needs to be done, individuals, such as those who have so far contributed
to this research, will be forced to keep any information obtained
to themselves to enable them to be remunerated for their contributions.
