Uses
A decoction or infusion of the wood is generally considered a strong emmenagogue and astringent. It is used to cure tuberculosis, diarrhoea and dysentery, and also used as a vulnerary. The seeds serve as sedative. In Thailand, the wood is used as a blood tonic, in the treatment of pulmonary diseases, as an expectorant and emmenagogue. A few drops of wood extract in drinking water is considered refreshing, due to the fragrance and colour it imparts. In Vietnam, it is considered an emmenagogue, haemostatic, and is prescribed in haemoptysis and post-partum haemorrhages. In Sabah, a decoction of the bark is drunk as a tea to treat tuberculosis and lumbago. The red dye extracted from the heartwood is used for colouring cotton, silk, wool and matting. In some countries it is used as a colouring agent for food.
