The dose makes the poison inferred
A reported rat oral LD50 for Eucalyptol is 2,480 mg/kg, the dose lethal to half the animals tested. Scaled by body mass alone:
173.6 g
a median lethal dose scaled to 154 lb (173,600 mg)
“The dose makes the poison” is a cross-species estimate shown as neutral science, not a threshold anyone should act on. Real toxicity depends on the person, not body mass alone.
