Ethno Botany Teak is a yellowish brown timber with good grains and texture. The wood is oily to the touch. Its natural oils make it useful in exposed locations. They make the timber termite and pest resistant and so durable even when not treated. It is used for outdoor furniture, boat decks, and other articles where weather resistance is desired. It is also used for cutting boards, indoor flooring, and countertops and as a veneer for indoor furnishings. It is brittle and therefore less suitable for articles requiring high resilience, such as tool handles and sporting goods.

Ethno BotanyTeak is a yellowish brown timber with good grains and texture. The wood is oily to the touch. Its natural oils make it useful in exposed locations. They make the timber termite and pest resistant and so durable even when not treated. It is used for outdoor furniture, boat decks, and other articles where weather resistance is desired. It is also used for cutting boards, indoor flooring, and countertops and as a veneer for indoor furnishings. It is brittle and therefore less suitable for articles requiring high resilience, such as tool handles and sporting goods. Also used for pulp and paper, MDF board and sawn timber. Local wood uses include tools, handicraft, construction and agro-forestry. Teakwood has been used for charcoal and fuel wood, it is a good fire starter, but nowadays it is usually considered too valuable for anything but pruning remnants and other rejects to be used in this way. Root bark and young leaves produce a yellowish-brown or reddish dye, which is used for paper, clothes and matting. In traditional medicine, a wood powder paste has been used against bilious headaches and swellings and internally against dermatitis or as a vermifuge. The charred wood soaked in poppy juice and made into a paste has been used to relieve the swelling of the eyelids. The bark has been used as an astringent and the wood as a hair tonic.
Animal / Plant HostCaterpillar of Hyblaea and Pyrausta feed on teak leaves. Teak is a host plant for caterpillar of the Endoclita moth, several woodborers and other Lepidoptera including Turnip Moth. Crowns are often host semi-parasitic mistletoes, such as Loranthus spp. and Dendrophthoe falcate.
