 ==== Uses ====
-Iroko wood
 The timber is used for a variety of external and internal purposes including boat-building, domestic flooring, furniture and outdoor gates. From the late 1990s, it was used as part of the txalaparta, a Basque musical instrument constructed of wooden boards, due to its lively sound. Iroko is one of the traditional djembe woods. Iroko wood was the wood chosen for the pews in the Our Lady of Peace Basilica.

 They also claim that the spirit of the Iroko can be heard in houses which use iroko wood, as the spirit of the Iroko is trapped in the wood. In Nigeria the iroko wood is of much lower quality due to soil conditions as well as root-rot. Some Westerners refer to the wood as "poor man's teak".

-Color/Appearance: Heartwood is usually a yellow to golden or medium brown, with color tending to darken over time. Pale yellow sapwood is clearly demarcated from the heartwood.
+The tree is feared in some cultures where it originates and hence is shunned or revered with offerings. Yoruba people believe that the tree is inhabited by a spirit, and anybody who sees the Iroko-man face to face becomes insane and speedily dies. According to the Yoruba, any man who cuts down any iroko tree causes devastating misfortune on himself and all of his family, although if they need to cut down the tree they can make a prayer afterwards to protect themselves.

+**Color/Appearance:** Heartwood is usually a yellow to golden or medium brown, with color tending to darken over time. Pale yellow sapwood is clearly demarcated from the heartwood.
-Endgrain: Diffuse-porous; large to very large pores in no specific arrangement, very few to few; solitary and radial multiples of 2-3; tyloses common; growth rings indistinct; medium rays visible without lens, spacing wide to normal; parenchyma banded, paratracheal parenchyma vasicentric, aliform (winged and lozenge), and confluent.

-Workability: Generally easy to work, with the exception of its interlocked grain, which may cause some tearout during surfacing operations. Also, deposits of calcium carbonate are sometimes present, which can have a significant dulling effect on cutters. Iroko glues and finishes well.

-Allergies/Toxicity: Although severe reactions are quite uncommon, Iroko has been reported as a sensitizer. Usually most common reactions simply include eye, skin, and respiratory irritation. Iroko can  also cause other health effects in sensitive individuals, such as asthma-like symptoms, boils, and hypersensitivity pneumonitis. See the articles Wood Allergies and Toxicity and Wood Dust Safety for more information.
