Research and biological activities
Volatile oils from Centipeda minima have been shown to modulate anti-inflammatory action by inhibiting inflammatory cytokines in a rat model. In a related study, C. minima eased allergic rhinitis by slowing the infiltration of eosinophils and the proliferation of mast cells.
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.
Phylogeny
On 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. Centipeda racemosa (Snuffweed) is the sister to remaining species, which is also the only consistently perennial representative in the genus. Centipeda pleiocephala (Tall Sneezeweed) and C. nidiformis (Cotton Sneezeweed) constitute a species pair, as does C. borealis and C. minima (Spreading Sneezeweed), all sharing the symplesiomorphic characters of spherical capitulum and convex receptacle with C. racemosa. Another species group comprising C. thespidioides (Desert Sneezeweed), Centipeda cunninghamii (Old man weed, or Common sneeze-weed), C. crateriformis is well-sup- ported but then include the morphologically aberrant C. aotearoana, all sharing the character of having capitula that mature more slowly relative the subtending shoot. Centipeda elatinoides takes on a weakly supported intermediate position between the two mentioned groups, and is difficult to relate to any of the former groups based on morphological characters.
