Summary
Artemisia californica, commonly known as California sagebrush, is a dominant shrub in coastal sage scrub communities [PMID:32504539]. It is used traditionally in American Indian medicine for pain therapy [PMID:24281255].
Background
Artemisia californica is a long-lived shrub native to southern California and coastal sage scrub vegetation [PMID:35869688, PMID:32504539]. It exhibits clinal genetic variation and local adaptation across latitudinal aridity gradients [PMID:23505064, PMID:27935026].
Traditional uses
It is traditionally used by American Indians as a liniment for pain therapy [PMID:24281255]. It is also recognized as a traditional medicinal plant of the Chumash American Indians of Southern California [PMID:27482826].
Active compounds
The plant contains monoterpenoids, sesquiterpenes, flavonoids, and alkaloids [PMID:24281255]. Specific isolated flavonoids include jaceosidin, jaceidin, and chrysoplenol B [PMID:27482826].
Mechanism of action
Sesquiterpene lactones from the Asteraceae family (which include A. californica) may modulate PGE2 levels by decreasing COX-2 activity and expression [PMID:30976671]. The flavonoid jaceosidin has demonstrated in vitro inhibition of the enzyme enoyl reductase (FabI) [PMID:27482826].
Clinical evidence
Evidence DPain (Acute and Chronic)
A liniment from Artemisia californica has been tested on patients with acute or chronic pain conditions with great success [PMID:30976671].
Evidence DBacterial Infection (E. coli)
Dichloromethane-soluble fractions and specific flavonoids (jaceosidin and jaceidin) exhibited antibacterial activity against a ΔtolC mutant strain of Escherichia coli in vitro [PMID:27482826].
Safety & adverse effects
Volatile materials produced by the leaves of Artemisia californica have been shown to inhibit the root growth of Cucumis and Avena seedlings [PMID:17833745].
Evidence summary
The evidence is primarily based on traditional use reports, in vitro laboratory studies, and ecological research. There are no randomized controlled trials or systematic reviews provided to support clinical efficacy.
