Theobromine poisoning, also informally called chocolate poisoning, is an overdosage reaction to the xanthine alkaloid theobromine, found in chocolate, tea, cola beverages, and some other foods. Median lethal (LD50) doses of theobromine have only been published for cats, dogs, rats, and mice; these differ by a factor of 6 across species. At doses of 0.8-1.5 g (50-100 g cocoa) per day sweating, trembling and severe headaches were noted. Limited mood effects were shown at 250mg/day and negative mood effects above.
