Question: Does hydrogen peroxide cause vomiting in humans?
I'm talking about he 3% kind. And if yes, how much?
Answers:
Yes it can. How much depends on the person, but even a capful can make you sick. It's not something you want to swallow at all if you can avoid it because it can be poisonous if you ingest too much.
