Argentine Lignum Vitae (Bulnesia sarmientoi)

View More Images Below

Common Name(s): Verawood, Argentine Lignum Vitae

Scientific Name: Bulnesia arborea, Bulnesia sarmientoi

Distribution: Central America and northern South America

Tree Size: 40-50 ft (12-15 m) tall, 1-2 ft (.3-.6 m) trunk diameter

Average Dried Weight: 74 lbs/ft3 (1,190 kg/m3)

Specific Gravity (Basic, 12% MC): 1.01, 1.19

Janka Hardness: 3,710 lbf (16,520 N)

Modulus of Rupture: 25,730 lbf/in2 (177.4 MPa)

Elastic Modulus: 2,272,000 lbf/in2 (15.67 GPa)

Crushing Strength: 10,830 lbf/in2 (74.7 MPa)

Shrinkage: Radial: ~6%, Tangential: ~8%, Volumetric: ~13%, T/R Ratio: ~1.3

Color/Appearance: Heartwood color can range from a pale yellowish olive, to a deeper forest green or dark brown to almost black. The color tends to darken with age, especially upon exposure to light (see light-change color photo below). Pale yellow sapwood is clearly demarcated from heartwood. Quartersawn grain has a unique feathered pattern when viewed up close.

Grain/Texture: Grain is straight to spiraled or slightly interlocked. Fine even texture with very high natural luster.

Endgrain: Diffuse-porous; small to medium pores in wavy radial rows, moderately numerous to numerous; dark-colored heartwood deposits present; parenchyma vasicentric, and confluent; narrow rays, normal to close spacing.

Rot Resistance: Verawood is reported to be very durable for outdoor use and is said to last almost indefinitely in direct ground contact; Verawood is  also resistant to insect attack.

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

Odor: Verawood has a distinct, perfume-like fragrance that lingers even after it has been machined.

Allergies/Toxicity: Verawood sawdust has been reported to cause sneezing, and the closely related 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: Should be priced in the mid to upper range of imported exotic woods. Turning blanks and other small pieces are most commonly available, comparing similarly with other tropical hardwoods such as Cocobolo or Bocote. Larger pieces of lumber are less common but are also available.

Sustainability: This wood species is in CITES Appendix II, and is on the IUCN Red List as conservation dependent. Cessation of any current conservation programs would likely result in a vulnerable or endangered status.

Common Uses: Tool handles, mallet heads, bearings, bushings, boatbuilding, pulley wheels, heavy construction (in areas where the tree grows locally), and turned objects.

Comments: Verawood has very similar appearances and working characteristics to Lignum Vitae, and is sometimes referred to as Argentine Lignum Vitae. Technically Verawood is Bulnesia arborea, and Argentine Lignum Vitae is Bulnesia sarmientoi; though the two woods are so close in appearance and working characteristics that they have been combined on one page for simplicity’s sake. All the scans listed here are from Bulnesia sarmientoi. 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.

Recent genetic tests have shown that the two commercial Bulnesia species belong in a separate genera, which the initial researchers proposed to be placed in Gonopterodendron[1]Godoy-Bürki, A. C., Acosta, J. M., & Aagesen, L. (2018). Phylogenetic relationships within the New World subfamily Larreoideae (Zygophyllaceae) confirm polyphyly of the disjunct genus … Continue reading, though subsequent classifications have placed these species in the genus Plectrocarpa.

Since trade of genuine Lignum Vitae is restricted, (and is included in the CITES Appendix II), Verawood is a popular substitute: yet even this species (Bulnesia sarmientoi) has been included in CITES Appendix III, though it is not as restrictive as Appendix II.

Scans/Pictures: You can see from the picture(s) in the lower right that the wood is capable of turning a deep, almost forest green. Since there was a sticker above the area with the much lighter yellowish-olive color, it would stand to reason that this dark green color change came about through exposure to light.

My 95 year old father used to turn plates. I found this one and asked what kind of wood it was made from. He can’t remember the name but says on rare occasions it has this greenish tone. The plate shown is about 15” across and it is very light in weight. Any thoughts on what type of wood it is made from?

Kimberly Guzman

Can you tell me what kind of wood this is? I’m stripping an old desk with laminate and this is what is underneath.

Kimberly Guzman

Thank you for responding! I

Rob Wilkey

Just wanted to share some images of how rich these colors can become with some age and exposure. This is a ladle dish I made a little over a year ago. It sees frequent use – getting splashed with hot oil and other cooking debris on a daily basis – and it lives right underneath a window. The colors on the exposed side have darkened to a rich emerald green with streaks of turquoise, straw, and burgundy. The underside hasn’t changed as much due to less UV exposure, and is mostly still shades of brown with some green flakes.


Hi Eric
Can you confirm that this block is not Lignum Vitae?
I bought this as true guaiacum spp. But the end pores look like verawood?
It does smell like perfume and the density is about 1,2 kg/m3.
Is it possible to distinguish Bulnesia arborea from Bulnesia sarmientoi just form
Wood samples? thanks


Letter openers from verawood

Kathy Fowler

Hello Eric, I have been looking for a site like this to help me identify the type of wood that this table is made of. It is an old table that belonged to my Grandmother and had been painted white for what looked like a long time. The first picture is right after I had used a small hand sander to take the old paint off. The second picture was right after I applied 2 thin coats of Polyurethane, no stain at all. Thank you for providing this site, I look forward to hearing from you and finding out what… Read more »

Michael Dake

With the yellow popular, how do you recommend refinishing the table

Michael Dake

I just sanded down an old table. It has various colors in the wood that was used.
Can you tell by my picture what type of woods that was used to put this tabletop together.
The dark colors are actually a green .


I have a table that I just sanded down like this too! Curious as to what year you estimate your table?

Mike Duffy

Hi Eric, I’ve recently come across an off-cut of a very heavy wood I’ve had for a long long time and thought it time to work out what it might be. I’ve worked out that it has an average SG of 1.2 & investigating the end-grain I think it must be Verawood. It’s a fairly dark reddy brown – no green or yellow. I’m attaching some photos and would appreciate your input. The photo names should describe what the views are but they are (1) end grain & radial view (2) Tangential view (3) End grain (4) best effort for… Read more »

Mike Duffy

Hi Eric, thanks for your reply. I think that maybe my end-grain photo didn’t keep to scale – as I cropped and tidied it up a bit – so it probably looks larger than it should. I have a sample of Jarrah and the pores on that are about 40% to 50% larger than my mystery wood. Also the pore arrangement looks very different. All very puzzling as my mystery wood definitely has an average dry weight of 1.2 and neither of the Eucalyptus (Jarrah and Karri) seem to come near that. However ref your ironbark suggestion I came across… Read more »

mike duffy

Hi Eric, first off I’d like to thank you for providing such a great site..with so many ways of searching for woods. Your book is also very well laid out. Now that I’ve become a wood nerd, I’ve been using both resources quite a bit recently. Every time I come across a new piece of wood I have to find out what it might be! As for the long discussion about my particular piece I wondered if it might be some sort of Acacia, maybe Gidgee. I never realised that the Acacia genus was so huge (apart from all the… Read more »

mike duffy

Hi Eric, I’ve previously had a try with a UV LED bulb but it didn’t work for me.. I tried it with Jatoba and Afzelia, following your recommendations. Maybe I’ll need to buy a UV backlight flourescent tube.


Mike, I would agree with Eric, this piece does not look like Verawood (colour and endgrain is probably more related to a different species). By chance I have got lots of Verawood/Arg. LV and I have taken the time to inspect several pieces -also comparing them with Lignum Vitae- Try to file/sand it, if you would get a nice -and lasting smell- I could be wrong…

Mike Duffy

Hi Jose, yes I now don’t think it’s Verawood but have come round to the idea that my wood sample is IPÊ – see my earlier reply. Thanks for your interest. Mike


No problem Mike. It could be Ipe (although Ipe normally is greener), but could also be Sucupira Vermelha (Bowdichia spp)

Mike Duffy

Hi Jose, I had a look into your suggestion for Sucupira. In my book it only mentions Black Sucupira (Bowdichia nitida), not Vermelha. Certainy the face grain looks a good fit. In my book it states … “The heartwood is a dull reddish-brown to dark chocolate-brown with light yellow paremchyma markings which are noticeable on quartered surfaces as a striped figure”. On my quartersawn surface (see 1st photo) there are light coloured ‘misty’ type markings (flecks?), so maybe these are the paremchyma? I was coming round to my piece being Sucupira until, by chance, I came across a German website… Read more »


Hi Mike, there is also Amarela & Vermelha (it is easy to find the names in Brazilian – I’m not from Brazil though, I’m Spanish :)

From the pictures you provided it looks like closer to IPE…

Agreed, definitely a learning exercice!

Rob Wilkey

Mike, I agree on visual inspection with your identification of it as Ipe, but I’ve gotta ask – what does it smell like when you cut or sand it? Ipe has a scent that to me smells like root beer. I’ve never worked with a wood that smelled quite the same so that’s my go-to test when I think a piece might be Ipe

Mike Duffy

Hi Rob & Jose, I only have a few relatively small pieces of this mystery wood so I haven’t worked it much other than to prepare the faces for closer inspection. I’m still not convinced that this is IPE as it doesn’t have a distinctive smell when worked. Also, when first cut it looks a rich pink, then light crimson .. no where does it look green. When sealed it is a deep crimson brown colour. Looking at the pictures on the hobbithouseinc site, for Sucupira, many of the end-grain ones look very different to the one I found.. some… Read more »

Rob Wilkey

I’ll admit I’m a little stumped. The first and second pictures you linked at the top of this thread, “(1) end grain & radial view” and “(2) tangential view)”, makes me think of Katalox ( due to the color, yellow veins, and the way that it can show ray flakes when cut at certain angles The endgrain photos look a lot like Jarrah (, although as you mentioned, Jarrah seems to usually be lighter than what you’re measuring for these pieces. That last photo you linked above threw me another curveball – as those distinctive tiger-stripe lines are an unsual… Read more »

Hi, was wondering if this might be verawood. It’s very dense and heavy. Came from a mixed lot of hardwood. I can see faint traces of green in it. It’s at least 20 year old lumber.

Leslie Elliottsmith

I was wondering if this is verwood. It is extremely hard. A neighbor who was a woodworker died and kids threw it out a large 3x3x4ft piece. I used my bandsaw to make some t track clamps.

Leslie Elliottsmith



Would verawood be used in a laminate/veneer in the 1930s or 40s? I was sanding a sapele/mahogany veneer, apparently went too deep, hit a distinct green and yellow cross grain. Was surprised and bummed, but also curious how it might pull if I leave the wear and urethane as is?


I agree with Eric – it will most likely be poplar. Poplar is a very popular wood base for veneered furniture, or for parts that are hidden from view.

Ed Davidson

End-grain view of a Verawood yo-yo. Easy to turn and finish. Smells good too.

Mari Thomas

Found this piece at a thrift store and starting sanding it to reveal this beautiful green colored wood!! One side is green and the other side is normal wood hue. Can you identify this?


I am refinishing a little vanity that came from my great Grandmothers place originally. As I stripped off the years of accumulated stains and varnish I was delighted to find initials carved into the surface of a couple of the drawers and the top surface belonging to my long gone Great Uncle. The next surprise is this small section that has a greenish hue totally different from the rest of the piece. Can you identify what type it is?


Hello! Thoughts on this bowl? Based off the thumbnails, argebtine lignum vitae is the closest I found to a match

David campbell

Any harm with this being a kitchen utensil handle that will get washed?


With this wood are also made wristwatches such as this photo, the Italian brand Woodstar Milano. https://woodstar.itcomment image


Really very nice


I like to inform the wood community,

Verawood is a beauitful green wood. HOWEVER, there is something that I had to learn the hard way, since I did not read this testimony from anyone: While Verawood often times change colors for the better, it is highly susceptible to heat. Once exposed to too high of a temperature (80 degrees F), the wood changes color NOT for the better: it has a bad habit of reverting back to its original Olive-Hazelnut color. Keep it away from heat, if you want to keep its green!!

Dave Adams

Can confirm as well, I have a watch made out of verawood and has turned more brown than green after wearing it to my outdoor job here in FL.

It still looks great and smells amazing though.


There are two species of “lignum vitae” . One is Bulnesia arborea from Brasil and Colombia also known as verawood or maracaibo,the other more fragrant from Paraguay is Bulnesia
sarmientoi or Palosanto. These are two different species and this article is actually not correct.


I turned a piece of this to make a handle for a pizza cutter kit that I bought. It does clog sanding belts but a rubberized belt cleaner will renew the sanding belt. I finished it with a tung oil mix.

Darin Kel J

I love the smell of this wood, though it clogs power belt sanders


smells like citrus

A neighbor gave me a slab of “Teak” that he used to make some replacement board for his boat long ago. He no longer owns the boat, but he enjoyed it very much. The “teak” is actually Argentine Lignum Vitae Somewhere I recall that Tung Oil is a good finish material for this type of wood. I used a 50/50 mix of tung oil and mineral spirits (so the oil would go farther into the grain). Attached is a photo, however the true color is more green. I believe the red below the bowl resulted in a warmer result. Thanks… Read more »


This is being sold under the name of ‘Green Sandalwood’ because of its rich aroma which makes it good for prayer beads too.

Tom C

I am not sure how long it takes to change color. I understand that most woods change color from one of two exposures:
Exposure to UV Light (the sun)
Exposure to Oxygen
I would think that a UV blocking finish (sometimes used to treat wood decks) may delay the change. I don’t think you can ever stop the oxygen exposure unless it is cast in resin.

Sorry that I can not help you any more than this. I believe the wood that I got from my neighbor was at least 5 – 10 years old.


Anthon Noire

i was working on a handle and when i sanded it around a month ago, it came up a warm caramel brown, but then i let it sit, indoors exposed but out of the sun, and its since turned an obvious darker green.


The deep jungle greens in this wood seem to be entirely based on the oils that cover the surface. I experimented a little bit and found that hanging a work-piece between two high powered lamps gives you a color change over night. I tried a few sealants and found that solvent based was the worst for preserving the color, oil based is somewhere in the middle and water-based polycrylic seems to preserve it the best of the ones I tried. It seems like the more the sealant interacts with the oil on the surface the duller the color gets.

Francois Sarrazin


I am about to enter into a relationship with verawood as a pen turner. I would like to know if the colour change still happens after the pen has been treated with French polish and wax. If so, approximately how long does it take?

I started sneezing within a minute of beginning to sand some verawood. I went ahead and continued, using planes instead… after a while my eyes, sinuses and the skin on my upper cheeks all were burning. It also left a hard crust on the edges of tools, rather like surface rust – not waxy but dry, brittle crust quite stuck to the tool edge, needs scraping off very often.

That said, it is beautiful, hard wood. The herringbone grain is fantastic.


Very nice site in deed.
I like the structure and the layout.
Plain information, fast, easy.

Here in Argentina Verawood is pretty much known as “Madera de palo santo” or just “palo santo”.

Maybe worth adding that name.



hasta luego.
