- Material Uses: The Kwakwaka’wakw shamans wove grand fir branches into head-dresses and costumes. The Hesquiat used the branches for incense and decorative clothing for wolf dancers. The Okanagan used the wood and bark to build canoes. The Salish used the bark to make a brown dye to apply to baskets. The knots in the wood were shaped, steamed, and carved into fish hooks by the Ditidaht, Salish, and other coastal groups. Pitch made from the bark’s resin has been applied to bows and paddles to secure grip.
- Medicinal Uses: The bark has been mixed with nettles to create a tonic and decoration for bathing. The Lushootseed have boiled its needles to make medicinal tea for colds. The Hesquiat mixed the pitch of young grand fir trees with oil and rubbed it on the scalp as a deodorant and to prevent balding. The bark has been mixed with other barks to make an infusion that was drank to cure internal injuries.
