Restoration and Conservation
- Provides food for and is pollinated by butterflies
- Establishes rapid tall herbaceous cover and stabilizes soil in disturbed areas
- Tlingit prepared the roots for blood disease remedies
- Nuxalk would use the roots to make tea for stomach pains, gonorrhea, and as a diuretic
- Roots were boiled in mountain goat grease for treating smallpox
- Kwakwaka’wakw would dry the root, soak, scrape, and then held it in the mouth as a type a cough medicine, like cough drops
- Lummi chewed the leaves to help cure smallpox
- Skagit burned the twigs (maybe roots too) and used the ashes mixed with bear grease to create a salve for swellings, particularly for the throat. They would also make a root infusion tea to cure colds and sore throats.
- Klallam would make the same salve but use it on sores that wouldn’t heal
- Mainland Comox would steep the roots and drink the roots to heal any swelling or even bath the swelling in the solution. They would burn the whole plant to make a charcoal that they could then use to reduce swellings or add some charcoal to water to prevent internal bleeding
- Root infusion teas were given to Squamish women right before birth to help start the internal healing process
- Makah ground the root in water and ingested it for kidney pains, and they would chew the leaves as a remedy for spitting up blood and signs of TB. They also had their own medicine for gonorrhea using the roots
