If you lived during Old Testament days, you would use olive oil to wash a sick person's head. You would spread honey over a cut with a tool that looked a lot like three paintbrushes held together with rubber bands. You would rub yeast on a baby's hurting gums or give garlic to someone with a toothache. (Caution: Don't try these remedies on yourself or friends.)
