Cyanthillium cinereum (also known as little ironweed and poovamkurunnal or poovamkurunnila in Malayalam, and monara kudumbiya in Sinhalese) is a species of perennial plants in the sunflower family.

and has become naturalized in Australia, Mesoamerica, tropical South America, the West Indies, and the US State of Florida.

[8] The species can be confused with Emilia sonchifolia, but the flower bracts of the latter are much longer and vase-shaped.

[citation needed] Cyanthillium cinereum has been used for smoking cessation in Thailand and other countries, and as relief for the common cold.

[9] It used to be called Vernonia cinerea, but apparently there was a taxonomic update, sometime prior to early 2014.
