Poison Antidote...

I sure hope you don't try this because of one of the recipes!!  
(Better yet, don't  try it at all...call 911 and/or your local 
number for poison control.)  I publish it here because I found 
it tucked away in an old family cookbook.  jim

When poison has been swallowed no emetic is better than mustard.
Mix three teaspoons with a cup of warm watter and swallow at once
the stimulative action upon the stomach cause that organ to reject
all its contents the poisonous ingredients with the rest.
It is one of the quickest of all emetics and the Most harmless.
