Liquor ammonie was an antidote for snake bites in the late 19th century. George Halford, a medical professor at Melbourne University promoted ammonia injections to stimulate the heart and reinvigorate the blood. Inspired by experiments in dogs, his suggestion to intravenously dose snakebitten patients with an acknowledged poison was certainly controversial. The prevailing treatments, for doctors and laity, were ligature, cutting and sucking the wound, rest (or vigorous exercise), and prodigious quantities of alcohol. Support for ‘Halford’s injection’ nevertheless grew: Victorian doctors, chemists and citizens extolled its effectiveness in both human and animal patients.
