Put the water and pine needles in a pot with the lid on.
Bring the water and pine needles to a boil and then turn off the heat and let sit for 1 hour.
Using a metal strainer, strain out the pine needles.
Re-heat the tea.
Drink 1 to 3 cups a day at the onset of a cold. This tea can be very drying to your body, so only drink it occasionally or for a couple of days at a time.
