Botanical name: Euphorbia hirta Family: Euphorbiaceae (Castor family)
Asthma Weed is a slender-stemmed, annual hairy plant with many branches, growing up to 40 cms tall, reddish or purplish in color. Leaves are opposite, elliptic-oblong to oblong-lancelike, 1-2.5 cm long, blotched with purple in the middle, toothed at the edge. Flowers, purplish to greenish in color, dense, axillary, short-stalked clusters or crowded cymes, about 1 mm in length. Capsules are broadly ovoid, hairy, three-angled, about 1.5 cm.
Medicinal uses: Asthma weed has traditionally been used in Asia to treat bronchitic asthma and laryngeal spasm, though in modern herbalism it is more used in the treatment of intestinal amoebic dysentery. It should not be used without expert guidance, however, since large doses cause gastro-intestinal irritation, nausea and vomiting.
