The plant has traditional uses in Ayurveda. It is bitter, hot, sharp, and dry in taste. In India, it is known as "bhangra" or "bhringaraj". "Wedelia calendulacea" is known by the same names, so the white-flowered "E. alba" is called white "bhangra" and the yellow-flowered "W. calendulacea" is called yellow "bhangra".In Southeast Asia, the dried whole plant is used in traditional medicine, although there is no high-quality clinical research to indicate such uses are effective.
