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.[6]

In Southeast Asia, the dried whole plant is used in traditional medicine,[7] although there is no high-quality clinical research to indicate such uses are effective.

Phytochemistry

Eclipta prostrata contains various phytochemicals, such as coumestans, polypeptides, polyacetylenes, thiophene derivatives, steroids, sterols, triterpenes, and flavonoids.[8]
