The combination of fresh orange slices, balsam, rosemary, cinnamon and cloves create a beautiful natural aroma for the holidays.
You can also add in orange slices and sprigs as the day goes on. By the end of the day my pot usually has almost 2 oranges simmering and 10 sprigs of balsam. I let the water level go down so the balsam sits on top the oranges that are emerged in the water.
You should be able to get a few days of use out of this before you will need to replace it.
