The dose makes the poison inferred

A reported mouse oral LD50 for Benzoic acid is 1,940 mg/kg, the dose lethal to half the animals tested. Scaled by body mass alone:

135.8 g
a median lethal dose scaled to 154 lb (135,800 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.
