For a headache caused by stress, try a soothing cup of this tea recommended by Mary Bove, L.M., N.D., a naturopathic physician and director of the Brattleboro Naturopathic Clinic in Vermont: Blend one part each of the dried herbs wintergreen, willowbark and meadowsweet (available in most health food stores). Pour boiling water over a teaspoon of this blend, steep for ten minutes, strain, let cool to a drinkable temperature and drink.
