Cultivation and Marketing

Propagation
A. triphysa is propagated by direct sowing. It has been raised successfully by planting nursery-raised seedlings.
Management
Pollarding is recommended in managing A. triphysa under a 10 year rotation. Seedlings are vulnerable to weeds and shade.
Uses and Function
Shade or shelter: A useful shade provider. Soil improver: Leaf litter of A. triphysa on decomposition restores soil fertility. Ornamental: A tree often planted for aesthetic purposes. Intercropping: Used as live stakes for supporting black pepper (Piper nigrum). Other services: The dried bark and gum exudates are burnt as incense.
Timber: Wood is used for making boats, matches, fishing floats and weaponry accessories e.g. sword handles and spear sheaths. Gum or resin: A gum is obtained from stem cuttings of A. triphysa. Tannin or dyestuff: A dye obtained from the plant’s leaves stains satin black Essential oil: Aromatic oils are obtained from the bark. Medicine: The plant roots, leaves, bark and gum exudates are used as medicine in India.
