Mesua ferrea is a slow growing evergreen tree with very hard reddish timber, famous for its drooping new leaves flushed pink and its fragrant white flowers with a dense golden brush of stamens. It grows in the wet evergreen forests of the Western Ghats, Assam, the Andaman Islands and Sri Lanka and is planted around temples across India. In Ayurveda the dried stamens are Nagakesara, an aromatic astringent that stops bleeding, binds the bowel and steadies the stomach. It is one of the four aromatics of Chaturjata alongside cinnamon, cardamom and Indian bay leaf.

Nagakesara is the Ayurvedic astringent to reach for when bleeding and heat travel together. Its signature use is raktarsha, bleeding piles, as Nagakesaradi churna with butter and sugar; the butter cools the pitta while the stamens close the vessels.
