Just seen on Outrageous Acts of Science 2 guys eat the worlds hottest horse radish and they broke down why its hot and how you cant wash or mute the burn like a pepper and basically its a defense mechanism of the plant when 2 ingredients get combined it combines into allylisothiocyanate a VAPOR thats why it cant be washed out because the vapor has already enterd your nasal passages....so outlaw horse radish. Im still shocked some idiot hasnt tried vaping body fluids of different types.....yet.
