Euphorbia hirta (sometimes called asthma-plant[3]) is a pantropical weed, originating from the tropical regions of the Americas.

[4] It is a hairy herb that grows in open grasslands, roadsides and pathways.

It is widely used in traditional herbal medicine across many cultures, particularly for asthma, skin ailments, and hypertension.

[6][7] This erect or prostrate annual herb can grow up to 60 cm (24 in) long with a solid stem that is furnished with many yellow to reddish coarse hairs, and produces an abundant white latex.

The fruit is a capsule with three valves (creating 3 sides), uniformly appressed hairy, containing tiny (0.7–0.9 mm), oblong, four-sided orange to pink or red seeds.
