I don’t know its origins, but this email is making the rounds. And, for the record, my Dad used to suggest number 7 for all sorts of maladies:

AMAZINGLY SIMPLE HOME REMEDIES
1. If you are choking on an ice cube, don’t panic. Simply pour a
cup of boiling water down your throat and presto. The blockage
will be almost instantly removed.
2. Clumsy? Avoid cutting yourself while slicing vegetables by
getting someone else to hold them while you chop away.
3. Avoid arguments with the Mrs. about lifting the toilet seat
by simply using the sink.
4. For high blood pressure sufferers: simply cut yourself and
bleed for a few minutes, thus reducing the pressure in your
veins. Remember to use a timer.
5. A mouse trap placed on top of your alarm clock will prevent
you from rolling over and going back to sleep after you hit the
snooze button.
6. If you have a bad cough, take a large dose of laxatives,
then you will be afraid to cough.
7. Have a bad toothache? Smash your thumb with a hammer and you
will forget about the toothache.
