  Common Teak scientifically known as Tectona grandis is a tropical hardwood tree species placed in the flowering plant family Lamiaceae which includes fragrant Premna, as well as herbs like marjoram, basil, Holy basil, oregano, savory, thyme, lavender, lemon balm, bugle, motherwort, self-heal, wall germander, cat nip, ground ivy, Jupiter’s sage and hyssop and a whole host of other plants. Some forms of teak are known as Burmese teak, Central Province teak (CP teak), as well as Nagpur teak. The plant is native to south and southeast Asia, mainly India, Sri Lanka, Indonesia, Malaysia, Thailand, Myanmar and Bangladesh but is naturalized and cultivated in many countries in Africa and the Caribbean. The generic name comes from ‘tekka’, the Malabar name for T. grandis. The specific name, grandis, is Latin for large or showy. Few of the popular common of the plants are Teak, Bankok teak, Common teak, Indian oak, teak tree, teak wood, sagwan, Thaekku and thekku.

The tree is now planted in tropical to sub-tropical areas throughout the globe, not only for ornamental reasons but also in plantations for commercial timber production. Timber from this tree is an important tropical wood. Teak wood has a leather-like smell when it is freshly milled and is particularly valued for its durability and water resistance. The wood is used for boat building, exterior construction, veneer, furniture, carving, turnings, and other small wood projects. Teak wood is hard, durable, fine-grained, and resistant to decay if exposed to moisture and of attractive deep brown color. Teak wood is used in a variety of ways, including (a) for outdoor purposes, it is used in the manufacture of outdoor furniture, boat building, doors and window frames, and (b) for indoor purposes, and it is used for flooring, fine furniture and veneer. Teak is the national tree of Indonesia.

Plant Description

Common teak is a large, long, tropical, deciduous, hardwood tree reaching about 40–50 m tall. Bole is generally straight and branch less for up to 20 m and is up to 150(–200) cm in diameter and is often buttressed and may be fluted. In seasonal climates, the tree is deciduous, whilst trees grown in non-seasonal climates are semi-deciduous. The plant is found growing in mixed hardwood forests and normally prefers deep, well-drained, fertile alluvial-colluvial soil with a pH of 6.5 – 8 and a relatively high calcium and phosphorous content. Teak does not tolerate water logging or infertile lateritic soils. The root system is superficial, often no deeper than 50 cm, but the roots may extend laterally up to 15 meters from the stem. Twigs are stout, gray- brown, somewhat angled, lenticellate, initially covered in silvery to rusty pubescence; leaf scars nearly round to flat-topped. Bark is fibrous, grayish brown with shallow longitudinal fissures.


Leaves are large, elliptic or obovate, 20 to 30 centimeters long, pointed at both ends, usually wedge-shaped at the base, with entire margins. Upper surface of leaves are rough and without hairs and the lower surface is densely covered with grey or yellowish hairs. Young leaves are red in color but become dark green at maturity.


Flowers are numerous, short-stalked, and arranged in large, terminal, much-branched panicles 30 to 80 centimeters long. Calyx is small, broad, bell-shaped, and covered with stellate hairs, with sub-equal and spreading lobes. Whole calyx is ultimately enlarged, up to 2.5 centimeters long and forming a membranous, blade-like covering to the fruit. Corolla is white, smooth, less than 1 centimeter across, with sub-equal and spreading lobes. Flowering normally takes place from June to September. Pollination is done by insects like bees, flies and ants.


Fertile flowers are followed by round woody globose drupe with four chambers, hard and woody enclosed in an inflated, bladder like green spongy covering and 1.2-1.8 cm in diameter, ripening in winter. Fruits are pale green at first, then brown at maturity. Each fruit may consist of 1 to 4 seeds. Seeds are ovoid 6 mm × 4 mm, without endosperm.

Health benefits of Common Teak

Listed below are some of the popular health benefits of consuming Common Teak

1. Skin health

Teak leaves are cooling in nature thus can act as an anti-inflammatory agent for reducing the inflammation of the skin. Leaves can be decocted or squeezed and used for preparing herbal medicines for treating skin diseases. Leaves can also help to tackle pruritus, which is a skin condition marked by severe itching of the skin.

Wood can be used for treating leucoderma, which is a cutaneous condition with localized loss of skin pigmentation that may occur after a series of inflammatory skin conditions, post-dermabrasion, burns or intralesional steroid injections have taken place. Leucoderma skin condition is mostly a cosmetic problem thus it is neither contagious nor infectious. Oil extracted from teak flowers can be used for treating scabies. Scabies is a transmissible skin disease symptomized by the itching of skin with small raised red spots, caused by the itch mite.

Bark can be used for treating leprosy. It is worthy to note that leprosy is a contagious disease that affects the skin, nerves and mucous membranes by causing discoloration and lumps on the skin. In severe cases, leprosy can lead to permanent disfigurement and deformities.

2. Overcome Anemia

Teak leaf extract is supposed to overcome anemia, this has been proven by several studies done by scientists Togo. Stating teak leaf extract tested on mice was able to increase the concentration of hemoglobin, platelets, and hematocrit and reticulocyte levels can increase endurance in young platelets.

3. Wound Healing benefits

Frontal leaves of teak can be prepared herbally and used for treating and healing wounds especially scald or burn wound. These researchers evaluated the effect of a hydrochloric extract of teak on experimentally induced wounds in rats. The models selected for the study were burn wound, excision wound, dead space wound and incision wound. An appropriate gel formulation was chosen for the application using cellophane membrane penetration.

An oral treatment with leaf extract produced a significant increase in the dry weight, breaking strength and hydroxyproline content of the granulation tissue in dead space wound. These researchers concluded that the oral (250 mg and 500 mg/kg body weight) or topical (5% and 10% gel formulation) application of teak leaf extract exhibit wound healing effects.

4. Supports Hair Growth

Oil extracted from teak flowers can be applied on hair for promoting hair growth. Additionally, another research reported that teak seeds are traditionally prepared and used as hair tonic mainly in the Indian system of medicine. Research was carried out to evaluate the petroleum ether extract of teak seeds and its effect on hair growth in albino mice. The 5.00% and 10.00% extracts added into simple ointment base were topically applied on the shaved denuded skin of albino mice.

5. Beneficial for Haemoptysis

Teak leaves can be used for treating haemoptysis. Haemoptysis is a health condition marked by the coughing up of blood.

6. Treats Gastrointestinal Disorders

Teak wood can be decocted and used for treating gastrointestinal disorders such as dysentery, stomach ache, piles and constipation.

7. Treats Headache

Studies reveal that the oil extracted from teak wood can be applied on the forehead for relieving headache. This is credited to the analgesic properties of this plant.

8. Treats of Anuria

Roots of the teak plant can be decocted and used for treating anuria. Anuria is a health condition marked by the failure of the kidneys to produce urine.

Qualities of Teak Wood


Teak wood is very strong and highly durable, which means that it is long-lasting, thus, can withstand wear, pressure, or damage. Teak wood is marked by its high density and as such does not easily get damaged or decay. Teak wood can also withstand water, moisture and adverse weather conditions. Teak wood furniture can last for a very long period of time, thus if you don’t want to keep wasting money on cheap soft furniture, always buy teak wood furniture as it can last for even more than hundred years.

Easy Maintenance

Teak wood furniture is very easy to clean and maintain.

Strong Resistance to Insects and Termites Attacks

Teak consists of powerful oils that give the wood a very high resistance to insects, fungi and termites attacks.


Teak wood is distinguished by its rich golden-brown color, which gives it an attractive appearance and outlook.

Supports the Ecosystem

Teak plant supports our ecosystem by beautifying the environment, ventilating the atmosphere and preventing erosion.

Teak Wood Furniture – Advantages and Disadvantages

Whether it is for furniture or flooring, teak wood has been a preferred solid wood material since many long years. Let’s take a look at the advantages and disadvantages of teak wood.

Benefits of using Teak Wood

1. Aesthetic appeal

Teak wood has a very attractive looking straight grain pattern coupled with a rich golden-brown color. In addition to this teak wood furniture also feels great to the touch, when compared with the newer engineered wood alternatives such as Particle boards, MDF and even plywood.

There are other hardwoods which are nearly as strong as teak, but it’s mainly because of its beauty that teak wood is so popular all over the world.

2. Quite Strong

Teak wood is a hardwood obtained from broad leaved deciduous trees, and it is remarkably strong, not only when compared to softwoods such as Mango wood or Pine wood, but also when compared with most of the other hardwood species of trees.

3. Very Durable

With proper care, teak wood furniture lasts for many long years (in many cases over 100 years). This is the reason why we still find antique teak pieces around. If you wish to buy furniture that will serve you, your children and then your grandchildren, then the best option is to go for teak wood furniture. Compare this longevity with particle board furniture which lasts only 2 to 3 years. This is because particle boards are not as strong and often get damaged while relocating or because of water. Durability can be counted as one of most significant advantage that teak wood offers.

4. Natural resistance to termites and insects

Teak wood has a natural oil content that resists termites (white ants), fungal stains, and also repels other insects that can destroy wood. Anyone who has ever had termites climbing on walls all over the house, and eating all the expensive wooden furniture before, will readily promise for how important this benefit is. This termite and insect resisting quality in turn increases the life span of wood, and is the reason why teak wood is superior compared to many other wood species.

5. Heat moderation

Teak wood like all other solid wooden furniture moderates heat. What this means is that it does not become too hot or too cold in the hot summers or the cold winters even when exposed to the elements. Though most people do not explicitly notice this particular quality of wood, it is one of the reasons why people instinctively like the touch and feel of natural wood furniture compared to its plastic or metal counterparts.

6. Resists rot and decay

Teak wood has a very high density, and does not rot or decay easily. This is the reason why it is so durable. Teak wood also has a natural resistance to several alkaline and acidic substances. Hence it does not get spoiled or stained easily.

7. High dimensional stability

Properly seasoned teak wood furniture does not warp or shrink too much. It retains its dimensions and is a stable material. Seasoning of wood involves drying the timber logs obtained from trees, so as to reduce its moisture content. Well-dried wood is not easily affected by climate changes.

8. Moisture-resistant

Teak wood has a good resistance to moisture and water. Other than its beauty, this is the reason why it is the preferred wood material used in ship-building for making the wooden flooring and decks. Because of its moisture resistance, teak wood is well suited for making indoor furniture as well as high quality garden furniture.

9. Can be hand-carved

From a carpenter’s or artisan’s point of view, teak is a fantastic material to work with, because unlike engineered wood products such as Particle boards, MDF or plywood, it can be hand-carved to increase its beauty. Most of the antique teak wood furniture often has interesting design patterns or shapes carved into the wood surface. Teak wood can be also be easily sawn and cut to desired sizes to make customized pieces of teak wood furniture as per client’s requirements.

10. Goes well with iron and other metals

Wood and metal are used a lot in combination. E.g. consider the table-mounted sewing machines of olden days, or the nails that are used in woodworking. It is important that the metals should not corrode or rust because of the wood. Though we cannot see it, woods are continually reacting to the environmental changes, and balancing their moisture content with the ambient moisture. What this means is that if the atmosphere is dry, the wood gives out moisture. And when such moisture comes in contact with metals it can be the cause of corrosion. Teak wood does not have this disadvantage, and has a good compatibility with iron and other metals.

11. Quite heavy

Teak wood is a very dense wood and has a high weight to volume ratio. This can be considered a beneficial trait, because a very basic rule in woodworking is that the denser and heavier a wood is, the stronger it will be. In addition to this most people have a distinct preference towards heavy and sturdy pieces of furniture, when it comes to buying solid wood furniture.

Disadvantages of Teak wood:

1. Very Expensive

This is the major drawback of teak wood is that it is very costly. The reason for this is the declining natural resources over the years. Demand is as high as ever, but supply has reduced. Other than the natural old-growth teak wood in forests, teak plantations (farms) have also flourished over the past years to try and meet this high demand.

Price of teak wood logs is indicated as per cubic feet price, and it is much higher compared to buying plywood. Add to this the payments required to be made to artisans for making a customized piece, or the commissions that dealers earn in the case of buying readymade teak wood furniture. It all adds up to the costs.

2. Hard to find high-quality wood

High quality and genuine teak wood is hard to identify for customers since it needs some knowledge and experience about woods. Perhaps the easiest way to fix this issue is to get suggestions and help from a trusted and reliable source.

3. Woodworking Tools get blunted

Teak is a hard material. From a carpenters point of view it presents a minor problem since the woodworking tools become blunt and need to be sharpened while working on the wood.

4. Needs care (needs to be polished once in every couple of years)

Compared to decorative laminates over plywood, solid teak wood furniture needs more care and maintenance. It needs to be polished every couple of years to maintain its beauty. There are different kinds of polish available called lacquer, but the easiest way is perhaps to use Touch Wood polish from Asian Paints that is specifically made for giving shine to wooden surfaces.
