If you happen to ever feel as if you have eaten something dodgy and either get food poisoning or feel as if it's coming on.
I went and sat in casualty department at the hospital for three hours, then went home unseen and sick as a dog.
I prayed please help me god I feel so sick, then I spied the onion, and remembered that during the war soldiers that ate onions never got food poisoning.
So with nothing to loose I chomped through three raw onion sandwiches . Within an hour symptoms subsided I was amazed to this day.
Eat a raw onion sandwich this will alleviate the symptoms.
Whenever in doubt I get an onion out. cheers...
