Nag Champa is one of the flowering trees of the Magnoliaceae family with bright Orange Yellow flowers. Michelia Champaka Alba is a close relative of Michelia Champaka producing white flowers with more or les the same aromatic compounds. Champaka is a holistic flower with hundreds of references in the folk lore & legends of Hindu mythology. It is also refered to in many classical medical textbooks of ancient India.
The fragrance resembles Yalang-Yalang, though Yalang-Yalang is sweeter in comparison to Nag Champa. These flowers produce an exquisite and heady fragrance just before sunset, when they bloom.
The petals resemble the hood of a snake. Hence the name Nag Champa. In many Indian Languages Nag means Snake.
