When I was a kid my mother would give me a tablespoon of foul-tasting castor oil as a laxative. Since learning about the ricin connection it's always been a source of bemusement whenever I think about it. Edit: presumably by 'a lot' you mean milligrams (by ingestion) and not micrograms. From my understanding eating 100mg would be a certain death sentence.
