Helenium autumnale
North American Asteraceae used by Native Americans as sneezing powder and for respiratory conditions.
Helenium autumnale (sneezeweed) is a North American asteraceous plant traditionally used by Native Americans for respiratory conditions and as a sneezing powder. Its primary active compounds, helenalin and other sesquiterpene lactones, exhibit anti-inflammatory and antitumor properties, though clinical evidence is limited to pilot studies and traditional use.
Helenalin exerts anti-inflammatory effects by inhibiting nuclear factor-kappa B (NF-κB) activation and reducing pro-inflammatory cytokines such as TNF-α and IL-6. It also induces apoptosis in cancer cells through mitochondrial pathway activation and caspase-3 cleavage. Sesquiterpene lactones may modulate glutathione levels and sensitize cells to oxidative stress, contributing to both therapeutic and toxic effects.
