Did you know?

The fizzing action of hydrogen peroxide on wounds comes from the enzyme catalase which breaks H2O2 into water and oxygen gas. Dogs have catalase in their stomach lining which is why ingested hydrogen peroxide induces vomiting — the enzyme creates gas bubbles that trigger the vomiting reflex.
