Northwest coastal tribes used sword fern leaves to line fire pits for cooking, and line baskets and drying racks. The rhizomes could be eaten by peeling and then steaming or roasting them. The leaves and/or stems could be made into tea for certain maladies.
This service that you perform is not only supplying the needs of the Lord’s people but is also overflowing in many expressions of thanks to God.2 Corinthians 9:12 NIV
