The flowers, young leaves and tender pods of the white flowered Agasti are edible. Young pods are eaten like string beans. Flowers are an excellent source of calcium, fair source of iron and very good source of vitamin B. It typically produces a soft wood, however, the density of the wood increases with age and the timber from 5-8 year old trees is used in house construction or as craft wood. The wood is of low quality. The tree has potential uses as pulp fibre, firewood, animal fodder or green manure and landscape decoration. It also has potential for reforesting eroded land and grassy wastelands. It’s excellent forage for growing goats.
Here in my state i.e. Orissa during the pious month of Kartik (which is November), the old women especially widows observe their habisha or fasting and worship Lord Vishnu in the form of Lord Jagannath. During Habisha they observe great penance, they don’t use oil, don’t take any non-veg food, or garlic, onion or spicy curry. They eat sunned (arua) rice, moong or masoor dal. Only limited and particular vegetables are allowed to take, like plantain, yam, and arum. The dalma or dal with these vegetables is cooked without oil or spice. Only a little bit of ghee is allowed. During this period of penance and austerity they cook and eat the leaves of Agasti as a leafy vegetable or saag. Most probably because of its good iron content it has been introduced traditionally as a good nutrition supplement.
All parts of this unique plant are useful. It’s an extremely useful tree. But I know no tree which is not useful :).
