[2][3][4][5][6] The genus is primarily native to Australia and New Zealand, with a few species extending the range northward into Asia and across the Pacific to southern South America.

[7] [1] Volatile oils from Centipeda minima have been shown to modulate anti-inflammatory action by inhibiting inflammatory cytokines in a rat model.

[8] In a related study, C. minima eased allergic rhinitis by slowing the infiltration of eosinophils and the proliferation of mast cells.

[9] A comprehensive investigation of the GC-MS chemical profile of C. cunninghamii and its biological activity showed that this species' extract contains novel compounds that possess anti-inflammatory and antioxidant properties.

[10] In 2012, Nylinder et al. published an estimation of the species tree phylogeny of the Australian/New Zealand genus Centipeda (Asteraceae) based on nucleotide sequence data.
