The state tree of both Maine and Michigan as well as the Provincial Tree of Ontario, the White pine is the tallest evergreen tree native to Eastern North America. Treasured for its beauty and the hint of green it offers when everything else is draped in white in the winter, its bark has also been explored by Native Americans medicinally for hundreds of years. Interestingly, similar uses of the bark of other species have also been used within Traditional Chinese Medicine as well.
Herbalists have traditionally used White Pine Bark to treat colds and coughs for ages. As an expectorant it can be used as a component in a variety of treatments that helps to loosen and expel phlegm and mucous. Some have also used it to increase circulation, and studies have shown it to be nature's second largest source of the potent antioxidants called proanthocyanidins.
