Eastern hemlock contains tannins (organic compounds), which are responsible for some of its medicinal properties. The bark has astringent properties, and the leaves contain significant amounts of vitamin C.
Traditionally, Eastern hemlock was used to treat digestive disorders, mouth/throat disorders, and diarrhea.
Although the Eastern hemlock is primarily used for lumber today, Native Americans used the tree's cambium (the tissue in a plant that produces new cells) in breads, soups and pemmican (dried, pounded meat mixed with fat and berries). Early settlers also used the tree in dying wool and tanning leather.
