Bhringraj- Eclipta alba : A rare medicinal herb

Eclipta alba or Eclipta prostrata L. or Yerba-de- tago is a small plant belonging to the family Asteraceae or Compositae. It is commonly known as False Daisy in English and Bhringraj in Sanskrit. The word Bhringraj literally means that which bestows hair the splendid black colour like that of a grand humming bee. Its other names are – Keshraj or Bhringraj in Hindi, Uchi-sumbal in Manipuri, Karisilanganni or Kavanthakara in Tamil, Kannunni in Malayalam, Galagara in Telugu, Ajagara in Kannada, Kesarda in Oriya, and Bhangra in Santali.

Habit and Habitat

Eclipta is a small and erect annual herb. Its stem is usually erect, flat or round, blackish green, profusely branched and pubiscent. Leaves are opposite, serrate, 3 to 5 cm long and blackish green in colour. The inflorescence is a head with 6 to 8 mm diameter. It is solitary, white, achene, compressed, and narrowly winged. Fruits are many seeded. Seeds are black and resemble cumin seeds. Flowering takes place during August- September months and fruiting occurs up to November.
Eclipta alba syn. E. prostrata is cosmopolitan in distribution. However it is abundantly found in India, China, Brazil and United States. The United State’s Department of Agriculture has declared this plant as endangered. Habitat destruction, reclamation of wetlands and changes in climate seem to cause pressure on the survival and distribution of this plant as a result of which it has become rare and endangered in many parts of the world including India.
