Common Name(s): Lignum Vitae

Scientific Name: Guaiacum officinale, G. sanctum

Distribution: Central America and northern South America

Tree Size: 20-30 ft (6-10 m) tall, 1-2 ft (.3-.6 m) trunk diameter

Average Dried Weight: 79 lbs/ft3 (1,260 kg/m3)

Specific Gravity (Basic, 12% MC): 1.05, 1.26

Janka Hardness: 4,390 lbf (19,510 N)

Modulus of Rupture: 18,450 lbf/in2 (127.2 MPa)

Elastic Modulus: 2,043,000 lbf/in2 (14.09 GPa)

Crushing Strength: 12,200 lbf/in2 (84.1 MPa)

Shrinkage: Radial: ~5%, Tangential: ~8%, Volumetric: ~13%, T/R Ratio: ~1.6

Color/Appearance: Heartwood color can range from a olive to a dark greenish brown to almost black, sometimes with a reddish hue. The color tends to darken with age, especially upon exposure to light. Color of genuine Lignum Vitae tends to be darker than that of Argentine Lignum Vitae.

Grain/Texture: Grain is interlocked, sometimes severely so. Has a very fine texture and an oily feel. Bare wood can be polished to a very fine luster due to its high natural oil content.

Endgrain: Diffuse-porous; small to medium pores, few; exclusively solitary; mineral deposits occasionally present; parenchyma diffuse-in-aggregates, vasicentric; narrow rays,

Rot Resistance: Lignum Vitae is reported to be very durable for outdoor use and is also very resistant to insect attack.

Workability: Lignum Vitae has a tendency to skip over-top jointer cutters on account of its extremely high density, and very light passes are recommended. Lignum Vitae will also dull cutters, and overall is considered quite difficult to work. Also, due to its high oil content and density, it’s very difficult to get a strong and reliable glue joint. However, Lignum Vitae is an exceptional wood for turning on the lathe, and finishes well.

Odor: Lignum Vitae has a mild, perfume-like fragrance.

Allergies/Toxicity: Lignum Vitae has been reported to cause skin irritation. See the articles Wood Allergies and Toxicity and Wood Dust Safety for more information.

Pricing/Availability: Trade of Lignum Vitae is restricted in CITES Appendix II, and prices for genuine Lignum Vitae are accordingly very high: and usually from questionable sources. Lignum Vitae is typically sold by the pound, (instead of the more common board-foot measurement), and since it is the heaviest wood in the world, this also makes it considerably expensive.

Sustainability: This wood species is in CITES Appendix II, and is on the IUCN Red List. It is listed as endangered because populations are severely reduced and exploitation for both its wood and resin extracts have continued for hundreds of years.

Common Uses: Tool handles, mallet heads, bearings, bushings, pulley wheels, and turned objects.

Comments: Lignum Vitae is regarded by most to be both the heaviest and hardest wood in the world. Its durability in submerged or ground-contact applications is also exceptional. Lignum Vitae has been used for propeller shaft bearings on ships, and its natural oils provide self-lubrication that gives the wood excellent wear resistance.

Unfortunately, Lignum Vitae has been exploited to the brink of extinction, and is now an endangered species. Verawood—a related wood species with similar working properties and characteristics—is commonly used as a substitute, and is sometimes called Argentine Lignum Vitae. Yet even this species (Bulnesia sarmientoi) has been included in CITES Appendix III, though it is not as restrictive as Appendix II where Lignum Vitae is found.

Though Verawood is in a different Genus than Lignum Vitae, (Bulnesia and Guaiacum, respectively) both genera are biologically classified in the same Family: Zygophyllaceae. Both woods are extremely hard, heavy, oily, and have a feathered grain pattern with a distinct brownish olive color.

The name Lignum Vitae is Latin, and means tree of life, or wood of life, which is derived from the tree’s many medicinal uses.

The smell of fresh cut Lignum Vitae is a breath of fresh air. Even better than pine-sol.

My cricket fan friend tells me that Lignum Vitae is (or maybe was) used to make cricket bails to be used in windy weather. If they still fall off the umpire can choose to play on without bails, and must decide if a hit constitutes a broken wicket or not.

I am a flutemake/fluteplayer from Connemara Ireland. I got a lovely piece of Lignum Vitae from a musician friend from Belgium and I wish to find out whether or this timber is suitable for making traditional Irish flutes, keeping in mind that the flute would be left in on your face when playing.

This wood is used for rudder bearing material in the U.S.S. Constitution.

I have a guitar with a nearly black Lignum Vitae fretboard and it’s the best I’ve ever played


loool, For sure that ain’t lignum vitae. It’s probably Ebony. Can you proof it’s L.V.? I don’t think so.Give the model number and I’m sure the specs will not say Lignum Vitae fretboard.


Density. If it is as you say, you’ll need to prove it. Don’t let it out of your sight.


That’s Gorgeous

I have been turning old bowling balls into potpourri bowls brilliant to work with

Ken Wiley

My favorite wood-carving mallet is made of Lignum Vitae. I love the feel of it the weight and balance of it is perfect for what I do. When I bought it 40 years ago I was told to put it in water occassionally to keep it in good shape but I never did, and it’s fine the way it is.

Graham Large

Worked with Lignum vitae at Chatham Dockyard on warship propellor thrust blocks / bearings.I believe policeman’s truncheons were once made of it. , also seem to remember staying at a chain hotel (Amadeus ) ? at two locations where a piece of Lignum vitae was used as a bar floor feature.Would not have thought too many guests would have known what they were looking at.


This wood was used as rail road ties here in Costa Rica.
Hand cut with an axe.
The better it was cut the more the rail company paid.
My 85 year old neighbor and friend still has the axes he used to cut ties with.


I will sail to costa rice to remove these railroad ties lol


What are the axe handles made from?

Peter Folske

I picked up about 40 pieces that are 18inch x 3×3. Rough sawed it was shipping material marked product of India this is a project just sanded no finish

Michael Woods

Is the oil in this wood foodsafe for cutting boards?


The dust of this wood is considered toxic with exposure to skin over time can cause dermatitis. Here is a link to woods and their toxicity and effects.

Wood has been banned by many countries for food blocks because bacteria has been found to survive in the cracks and knife scores even after submergence cleaning. White plastic is the alternative.


Hi i have 6 large lignum vitae rollers that have come off an 1800 period rack sawbench size is 23 inches length and 6″ diameter they have a steel shaft thro the middle just wondering if there is any value in these thanks

Jeff Herman

I LOVE this material for making tools in restoring silver because of its density and tight grain. I put a 1200-grit finish on the wood ends and use them to remove dents in trays because it doesn’t stretch silver the way steel does.

guy boor

I have a 2x2x8 inch pices of this wood it was given to me from a friend. I make tobacco pipes, I’m concerned about the the fumes or gas that could occurre from the natural oils in wood when the tobacco is burning in the smoking chamber. Would anyone know if this wood has ever been used for a Tobacco Pipe. Or if this wood was used in food or water containers application.

Carolina Hennig

In Paraguay they use it for cups for their national drink called Tereré. Google it, you’ll see. They call it Palo Santo there.


My father has a load of it in his shed from the 1970’s. Every now and again he will make a pan handle out of a bit. I had not idea it was so sought after.


Care to sell any of it? If so please email me at


Lignum Vitae is also used in leather working, specifically polishing the edges of straps and belts.

During the ’70’s I owned a Star class sailboat #2112. The skeg and rudder were made of
Lignum Vitae which was unpainted and had a 2″ split at the top of the rudder. I tried to repair the split and was unsuccessful. The boat was built in Chicago in 1942. Frames were white oak. The garboard planks were mahogany. The rest of the planking was white cedar. Each side was a single plank 30″ wide, 24′ long and 2″ thick. Not a blemish in either one. I doubt
that one could find wood like this today.


I’ve been looking for a naturally green wood for a custom butcher block. After much research this is the one that’s come up the most. Any pictures I’ve seen have been a darker colour (not green). Does anyone have any experience with Lignum Vitae? What would you recommend be done in order to have the wood turn green? (expose to sunlight? etc)


Thanks for the info, very helpful.

Dan Downard

True Lignum Vitae will still turn green even after you put polish on it. (if you can get it to stick to it) I have made a few rings out of it and finished it with CA glue, but it really didn’t need it as it can be sanded to a high shine. If you want to get good at sharpening your tools work with this stuff…..


My verawood matches your picture, it is nothing like lignum vitae in my experience. It was sold to me as lignum vitae; a hard lesson.


It is very easy to tell them apart. The Verawood endgrain runs mirror like through the whole piece.

I am an apprentice saddle maker in the U.S. and just received some tools
from a master saddler, David Boot from England. Some of the tools are
made from lignum vitae, including a masher and loop blocks. Both of the
types of tools are meant for extreme force, and are not only extremely
strong, but they are equally as beautiful.


I have a supported spindle with lignum on the tip and an insert in the support bowl. It spins really well and for a long time. It helps the tip NOT to become blunt and slow down.

I have a set of crown green bowls made from lignum vitae. Far better to play with than the more widely used plastic varieties.

Rod Reidnauer

I’m right in the middle of fashioning a set of 4-1/2 x 7 inch lignum vitae bearings for a 1200 lb flywheel. It is a bit rough on tools, but it sure is pretty, polished stuff just the way it comes off the saw. I have a picture of the bearings being constructed at

Don Rivest

Some older hydro-turbines used journal bearings made made from this material – for the same reasons as ship’s propellers. I’ve also understand that the block and tackle equipment in many older ships had bearings of Lignum Vitae. Cool stuff!


I had a mate that worked on the Queen mary he was the 34 officer & his job was to watch the main bearing on the prop shaft & put water on when needed the bearing was Lignum Vitae

Geoff Lusk

I have a Lignum Vitae cane that was given to my Great Grandfather at the opening of the Panama canal, this wood was apparently used in the construction of the canal.

late father had set of highland bagpipes made from this wood in 1925 by a maker in otago n.z. wood came from propeller bearings in old ship. beautifull soft mellow sound commented on by several piping judges over the years.
