What Is Palo Santo Resin

Palo santo resin is the concentrated tree exudate of Bursera graveolens, an aromatic dry-forest tree in the same botanical family as frankincense and myrrh. It may begin sticky and orange or green, then become thicker and harder as some of its lighter compounds slowly evaporate. It is a different ingredient from palo santo wood powder and from steam-distilled palo santo essential oil.

This is one of the most difficult ingredients we source. Palo santo is protected and tightly controlled in parts of its native range. Peru, for example, lists Bursera graveolens as Critically Endangered under national law, prohibits cutting live trees, and requires authorized management and traceability for legal harvest. Natural resin is a non-timber forest material, so its collection needs its own documentation rather than being treated as ordinary palo santo wood.

Those protections are a good thing, and they are part of what makes genuine, properly documented resin both valuable and scarce. We buy it in limited amounts, infuse the whole resin into tallow and oils, and filter the spent material back out. Because 3 Trees Tallow Salve is made in small batches around this rare ingredient, there may be seasons when it is sold out. We would rather wait for the right resin than replace it with something easier to obtain.

Traditional Use and Cultural History

Palo santo means “holy wood” or “sacred wood” in Spanish. Bursera graveolens has a living place in Northern Peruvian and southern Ecuadorian traditions that join physical care, household practice, cleansing, and spiritual life.

Ethnobotanical records describe palo santo wood and small stems used in fumigation and baths, as well as preparations connected with colds, coughs, discomfort, and rheumatic complaints. Among Saraguro yachakkuna in southern Ecuador, palo santo was documented in a culturally specific cargado prepared by macerating several plants in water or aguardiente.

Historical scientific writing also records palo santo resin or exudate in uses associated with pain and rheumatic discomfort. The records do not always separate wood, bark, smoke, resin, and oil, so we keep the preparation named whenever it is known. Even so, the resin belongs within a long relationship between people and this tree, not simply within modern fragrance culture.

Why We Love It

Whole Resin Holds More Than an Essential Oil

The first direct modern profile of naturally exuded Bursera graveolens resin was published in 2025. Researchers analyzed ethanol extracts from six resin samples gathered from 33 trees in coastal Ecuador and identified 36 volatile compounds. Limonene led the profile at an average of 51.9%, followed by menthofuran, beta-bisabolene, alpha-bisabolol, menthalactone, beta-bourbonene, valerianol, eudesmol, and other terpenes.

Researchers also emphasized that resin is a mixture of volatile and nonvolatile compounds and called for the heavier portion to be studied next. That is why the whole resin interests us. Distillation collects the compounds able to travel with steam, while the resin still holds material that does not simply distill away. Infusing the resin into tallow and oils gives compatible compounds a home in the fats that will touch the skin.

Helps Calm Irritated-Looking Skin

Alpha-bisabolol averaged 5.1% of the volatile profile in the direct resin study, although its amount varied naturally among samples. Separate research on a well-studied form of alpha-bisabolol found reduced TNF-alpha and IL-6 production in cell experiments, while topical application reduced swelling, lipid oxidation, and tissue changes in a mouse model of skin inflammation. In a 2023 study, topically applied Bursera graveolens essential oil reduced mouse-ear swelling by 25% and significantly lowered IL-8, IL-17A, and IL-23.

These studies used the isolated compound and distilled oil rather than our infusion, but I find the overlap valuable. A skin-calming terpene was identified directly in true palo santo resin, and exact-species research points in the same direction. That gives us a thoughtful scientific reason to value the resin for skin that looks red, stressed, or irritated.

Shows Antibacterial and Antifungal Potential

Essential oil distilled from fallen palo santo branches produced moderate-to-high laboratory inhibition against Staphylococcus aureus, Bacillus cereus, Listeria monocytogenes, Clostridium perfringens, Escherichia coli, Salmonella choleraesuis, and Candida albicans. In the 2023 dermal study, the oil was also active against Candida albicans, Candida glabrata, and Candida parapsilosis and was well tolerated in the skin models used.

Our whole-resin infusion is a gentler, less concentrated preparation, but these findings help us understand that palo santo’s volatile compounds are biologically active, not simply responsible for its scent. That adds another reason we appreciate the resin in skin care.

May Support a More Even-Looking Skin Tone

Alpha-bisabolol has also been studied for uneven pigmentation. In an eight-week study, 28 women applied an alpha-bisabolol cream daily to pigmented skin on the back and a vehicle cream to a comparison area. Most participants showed significant lightening in the area treated with alpha-bisabolol.

While the study used isolated alpha-bisabolol rather than a palo santo resin infusion, I find the connection fascinating now that alpha-bisabolol has been identified in true Bursera graveolens resin. It offers another possible way the resin’s chemistry may matter to the visible appearance of skin.

Quick Answers

Why can palo santo resin and 3 Trees be unavailable?

True resin reaches us in small, irregular lots. Legal harvest is limited by conservation rules, management plans, collection conditions, traceability, and what responsible suppliers can obtain in a given season. We make 3 Trees in small batches and will let it sell out when the right resin is not available.

Is palo santo resin the same as palo santo powder?

No. Palo santo powder is finely ground wood. Resin is the tree’s concentrated exudate. They share a botanical source and some related compounds, but their chemistry, texture, scent, and behavior in an infusion are different.

Why infuse palo santo resin into tallow and oils?

Many of the resin’s best-characterized terpenes are oil compatible, so fats give them a natural carrier. Infusion also lets us work with the whole resin rather than adding a concentrated distilled essential oil. The result is a rich resin infusion made for an oil-based salve.

Why use the resin instead of palo santo essential oil?

Essential oil contains the volatile compounds that travel through distillation. Whole resin also contains nonvolatile material that stays behind during that process. We choose resin because we want the broader botanical material and a softer scent held within the salve, not a formula built around concentrated essential oil.

Can palo santo resin help irritated-looking skin?

True palo santo resin contains alpha-bisabolol, and experimental research on that compound and on Bursera graveolens essential oil has found anti-inflammatory activity in skin models. I find that especially interesting for skin that looks red, stressed, or reactive, even though an infused resin product has not yet been studied directly.

Is palo santo resin antibacterial or antifungal?

Laboratory studies of concentrated Bursera graveolens essential oil found activity against selected bacteria and Candida species. Our whole-resin infusion is a gentler preparation, but the findings help explain why we value the tree’s active chemistry in supportive skin care.

What does palo santo resin smell like?

It is woody, resinous, warm, balsamic, lightly sweet, minty, and citrus-like all at once. The balance varies naturally by tree and batch, which is part of the beauty of a true forest material.

Is Bursera graveolens endangered?

The IUCN lists the species globally as Least Concern, while Peru lists it as Critically Endangered under its national law. Both can be true because one assessment looks at the species across its entire range and the other protects it within Peru. For us, the practical answer is that species identity, legal origin, collection method, and traceability all matter.
