quote from the following paper...
"Dr. Matas had occasion to prescribe it for a man suffering from asthma, the patient,
from a misunderstanding of the directions, took six or eight four ounce bottles of Peroxide of Hydrogen during one night,
and was not only not injured by this excessive amount, but actually believed that he had benefited."
