Hemlock has almost interchangeable properties with balsam fir. The needles are high in vitamin C and have also been used to treat scurvy. The Mi’kmaq, however, used the inner bark for treating scurvy. Some sources say that the bark and leaves of hemlock or spruce, not cedar, was the plant that cured Jacques Cartier’s men of scurvy. The Iroquois, Abnaki, Algonquin and the Native Americans of Delaware and Oklahoma have all been reported to use hemlock branches, applied externally or taken internally, for treating rheumatism and arthritis.
John uses hemlock as food, medicine, and shelter-building. The inner bark can be rinsed, dried, and ground to make a flour. The boughs are good for use in outdoor shelters. They provide soft, insulating bedding and a rain-shedding roof, assuming the boughs are placed right side up—as they are oriented on the tree.
