Artemisia douglasiana, known as California mugwort, Douglas's sagewort, or dream plant, is a western North American species of aromatic herb in the sunflower family.

[10] Although A. douglasiana can reproduce from seed, it is primarily propagated from division and spreading of its underground rhizomes.

[9][13] Artemisia douglasiana is used by Native American tribes as a medicinal plant to relieve joint pain and headaches, and to treat abrasions and rashes (including poison ivy).

It is also used to treat women's reproductive issues, including irregular menstruation and is occasionally used as an abortifacient.

It is commonly carried to ward off spirits of the dead and was smoked or drunk as a tea to induce vivid dreams.
