Its timber is highly esteemed for door and window panels, joinery and furniture especially for drawers, wardrobes, cupboards, kitchen and camp furniture, and musical instruments because of its lightweight, stability and durability. It is also used for bentwood articles. In boat building it is used for decking and for oars. Gmelina arborea is a popular timber for picture and slate frames, turnery articles and various types of brush backs, brush handles and toys also for handles of chisels, files, saws, screw drivers, sickles etc. The wood is also used for manufacturing tea chests and general purpose plywood, blackboards, frame core and cross bands of flushdoor shutters. In the instrument industry gambhar timber is widely employed for the manufacture of drawing boards, plane tables, instrument boxes, thermometer scales and cheaper grade metric scales. It is also used in artificial limbs, carriages and bobbins. It is an approved timber for handles of tennis rackets, frames and reinforcements of carom boards and packing cases and crates. Gamhar is used in papermaking and matchwood industry too.

Gmelina arborea leaves are considered good for cattle (crude protein – 11.9%) and are also used as a feed to eri-silkworm.

Chemistry

Lignans, such as 6“ - bromo - isoarboreol, 4-hydroxysesamin, 4,8-dihydroxysesamin, 1,4-dihydroxysesamin (gummadiol), 2-piperonyl-3-hydroxymethyl-4-(α-hydroxy-3,4-methylenedioxybenzyl)-4-hydroxytetrahydrofuran and the 4-O-glucoside of 4-epigummadiol, can be isolated from the heartwood of Gmelina arborea. The parent compounds are arboreol or gmelanone.

Umbelliferone 7-apiosylglucoside can be isolated from the root.

Five constituents, isolated from the heartwood of G. arborea, (+)-7′-O-ethyl arboreol, (+)-paulownin, (+)-gmelinol, (+)-epieudesmin and (−)-β-sitosterol, show antifungal activity against Trametes versicolor.
