            The edible portion comprises about 75% of the fruit and contains per 100 g: water  85 g, protein 0.7 g, fat 0.6g,carbohydrates 16.4g, fibre2.3g, ash0.5g, calcium 95mg, phosphorus 17mg, riboflavin 0.1mg, niacin 0.4 mg, phosphorus 17 mg, iron1.2mg, vitamin A 131 IU ,thiamine 0.06 mg, riboflavin 0.1 mg, niacin 0.4 mg, vitamin C93mg. 

 The seeds are salted and pounded to obtain an edible meal.

           The wood is used for general construction work and indoor woodwork.  It seasons well, is easy to work and rakes a beautiful polish. The heartwood is durable for interior work but very perishable when in contact with the ground.  The sapwood is very susceptible to damage by dry-wood termites.

Cultivation:

Medang kok grows chiefly in primary, lowland, inland forest, sometimes in coastal forest, rarely up to an altitude of 400 m.  In the Philippines it thrives in places with a distinct and season on a wide range of soil types,

The propagation is mostly by seed although it can be readily propagated by cleft grafting on its own or mango roots.  Grafted trees remain much smaller and have a more compact crown than seedlings..

Medang kok seems to be much hardier than mango as the common mango pests like leafhoppers, tip bores and seed borers do not affect this fruit..
