The internal investigation revealed that at the time of Edmonds' admission only one ampoule of tiger snake antivenene had been available, and the single ampoule of polyvalent antivenene had been withheld from use.
The latter could also be used in solid form--'Condy's crystals'--which remained a popular, albeit, useless remedy long after antivenenes had become widely available.
Although highly traumatic, they were probably more effective treatments than those offered by the medical fraternity before the development of specific antivenenes. Thus, there are numerous accounts of bush workers in remote districts removing envenomated parts of their anatomy with an axe or any other convenient sharp instrument, blasting fingers and toes off with firearms, or biting out the envenomated section with their teeth.
From this time it became clear that specific antivenenes would be required to counteract the bites from different species, with Martin also revealing that intravenous use was the only effective way the treatment could work.
The establishment of the Commonwealth Serum Laboratory (CSL) in 1916 hastened research into Australian shake venoms, even though the development and distribution of antivenenes was of relatively minor importance in the institution's vast array of medical endeavours.
