Bark/Twig: Bark is gray to reddish-brown, 6-9 mm thick, fibrous, separated into flat, connected ridges.

The wood’s light weight and resistance to decay makes it useful for a number of applications. The principal commercial uses of northern white-cedar are for rustic fencing and posts; other important products include cabin logs, lumber, poles, and shingles. Smaller amounts are used for paneling, piling, lagging, pails, potato barrels, tubs, ties, boats (especially canoes), tanks, novelties, and woodenware. The timbers were used to make the ribs in birchbark canoes. "Cedar leaf oil" is distilled from boughs and used in medicines and perfumes. Boughs are also used in floral arrangements.
essential oil of northern white cedar is used in cleansers, disinfectants, hair
preparations, insecticides, liniment, room sprays, and soft soaps.
The Ojibwa are said to have made soup from the inner bark of the young
twigs. The twigs are used by some
to make teas for relief of constipation and headache.
