I think Eclipta prostrata.

Hi

Eclipta prostrata is common plant. Eclipta alba is white Bhringaraja and Wedelia calendulaceae L is yellow Bhringaraja this is because of its flower color.

All the best

Eclipta alba is synonym of Eclipta prostrata.

Eclipta prostrata (L.) L. is commonly known as  "Bhringraja"
