Copaiba Oil (Balsam)

Copaifera spp. · also called Copaiba balsam, copaiba oleoresin, copaiba oil-resin

Copaiba oil is a golden sap tapped from Copaifera trees in the Amazon and a distilled oil made from it. Amazonian folk medicine has long used the sap, and a few small trials of gels on skin and teeth have been done. The evidence is thin, and copaiba should not be swallowed or put on skin undiluted. Adulteration with cheaper oils is common.

About Copaiba Oil (Balsam)

Copaiba is a sap from Amazonian trees, long used in folk medicine. The sap and the oil distilled from it are different products. Human research is limited to a few small trials, and safety information for swallowing, pregnancy, children and pets is missing.

Oleoresin or essential oil?

Copaiba oleoresin is the sap-like liquid from the trunk of Copaifera trees. Reviews describe it as made of lighter, volatile sesquiterpenes (such as beta-caryophyllene) and heavier resin acids (such as copalic acid). In one study of a Copaifera langsdorffii sample, the volatile part was about 22.5% of the weight and the resin about 77.5%.

A steam-distilled 'essential oil' keeps the volatile part. The acne trial used a distilled oil whose main compound was cis-thujopsene, not beta-caryophyllene. In other oleoresins beta-caryophyllene was the main compound, and amounts vary by species and origin. Products sold as 'copaiba oil' may be either, and the sources we read do not settle which. Several species are used: Copaifera reticulata is the most studied, then C. langsdorffii and C. multijuga.

Quality and the forest

Lab papers say copaiba oil-resin has not been standardized by industry or regulators and has often been adulterated with cheaper oils such as soybean oil, normally above 50%. A new screening method can catch gross adulteration but not low levels. In a study of 40 samples, two commercial samples lacked most of the characteristic compounds.

Two papers describe oleoresin tapping as a forest product that brings income to local communities and supports forest conservation. We found no study of how tapping affects the trees, so this page does not rate the sustainability of any product.

What the research shows

There are four small human studies and they do not agree on a preparation: an oleoresin hydrogel on skin tears (84 patients), a distilled oil gel on acne (2012, size not in the abstract), a dental gel after tooth bleaching (75 volunteers) and a report of three people with psoriasis. None is large, and none tested a scent or massage use.

Most copaiba research is in dishes and animals. A review of 232 records found in vitro work most common, mostly from Brazil, with germ-killing and anti-inflammatory activity studied most. These results do not show what the oil does in a person.

Tradition or eraDocumented useSource
Amazonian folk medicinePapers describe copaiba oleoresin as one of the most important traditional resources of Amazonia, used for medicinal purposes on the skin and by mouth, and widely used in Amazon folk medicine. The knowledge belongs to the peoples and communities who developed it; the papers do not name specific nations, and this page does not claim to.Cardinelli et al. 2023; Almeida Junior et al. 2026
Brazil, since the 16th centuryA 2026 review says copaiba has been used in Brazil since the 16th century as an anti-inflammatory and curative agent, and for esoteric purposes.Passos et al. 2026 (scoping review)

Isolated compounds versus whole extracts

Oleoresin and distilled oil are different products. The oleoresin is the whole sap-like liquid from the trunk: a volatile part (sesquiterpenes such as beta-caryophyllene, 22.51% of the weight in one C. langsdorffii sample) and a non-volatile resin part (diterpene acids such as copalic acid, 77.49%). Steam distillation collects the volatile part, so a distilled essential oil should lack the resin acids (our reasoning from the papers, not a statement they make). The acne trial used a distilled oil whose main compound was cis-thujopsene, not beta-caryophyllene. The skin tear and psoriasis papers used the oleoresin. Retail products labelled 'copaiba oil' may be either, and the sources read do not settle which.

Skin tear healing (oleoresin in a hydrogel)

Very low certainty

One trial in 84 older hospital patients compared a copaiba oleoresin gel (2% and 10%) with plain gel on skin tears. The 2% gel healed faster than the 10% gel, but the abstract does not clearly show a difference from plain gel. No side effects were reported.

1 studiesNot covered. This page gives no amounts and no ways of using the oil.

Studies, doses and limits

What the trials found

A double-blind randomized trial at a university hospital in Rio de Janeiro: 84 patients with a mean age of 67 (29 on 10% oleoresin gel, 28 on 2% gel, 27 on plain hydrogel). Copaifera multijuga oleoresin.

Results

The 2% gel healed faster than the 10% gel (p < 0.05); healing time across all three groups did not clearly differ (p > 0.05); wound size reduction could not be shown to differ. All wounds healed by the end of the study. No local or serious adverse effects.

Effect sizes as reported

p-values only in the abstract.

Why this rating

One small trial. The main comparison with plain gel was not clearly better, people who dropped out were left out of the analysis, and the 2% beating 10% only compares two strengths of the same gel.

Form and dose studied

Not covered. This page gives no amounts and no ways of using the oil.

Who was studied

Mostly men, mean age 67, with skin tears treated in one hospital.

Limits

Single trial; one hospital; completers only; a hospital wound gel is not a retail oil.

Why researchers looked

Copaiba oleoresin has long been used on wounds, so researchers tested it in a gel on a common wound in older people.

Traditional use

Sources describe copaiba oleoresin as a traditional resource of Amazonia, used on the skin and by mouth in folk medicine, and used in Brazil since the 16th century as an anti-inflammatory and healing agent.

Proposed mechanism Preliminary mechanism

Not shown in this trial. Lab work (see the science tab) points to antimicrobial and anti-inflammatory activity, but that is not proof of how a wound heals.

A proposed mechanism does not show that the effect happens in people.

The gel was a medical wound product used in hospital. See the Safety tab: this page does not advise swallowing copaiba oil or using it undiluted on skin. Contact dermatitis from copaiba balsam has been reported in a child.

Acne (steam-distilled oil in a gel)

Very low certainty

A small placebo-controlled trial from 2012 reports that acne-affected skin area fell more with a gel containing 1.0% steam-distilled copaiba oil than with placebo gel. The abstract gives no group sizes and no direct statistical comparison, and the placebo group also improved.

1 studiesNot covered. This page gives no amounts and no ways of using the oil.

Studies, doses and limits

What the trials found

A double-blind, placebo-controlled trial in volunteers with acne (number not given in the abstract) using Copaifera langsdorffii essential oil, steam-distilled from the oleoresin, in a gel.

Results

Acne area fell with placebo (p = 0.001) and fell more with 1.0% oil (p < 0.001). The linear model explained 26.8% of variation for placebo and 69.5% for the oil. The distilled oil's main compound was cis-thujopsene (46.96%), not beta-caryophyllene.

Effect sizes as reported

Model fit (r2) only; no difference between groups stated in the abstract.

Why this rating

Size, length and funding are missing from the abstract, the placebo group improved, and no repeat trial was found.

Form and dose studied

Not covered. This page gives no amounts and no ways of using the oil.

Who was studied

Volunteers with acne vulgaris.

Limits

Details not in the abstract; 2012; not repeated; one species and one preparation.

Why researchers looked

Copaiba is traditionally described as anti-inflammatory and antiseptic, so researchers tried a gel on acne.

Traditional use

The authors describe copaiba oleoresin as widely used in traditional medicine for anti-inflammatory, healing and antiseptic purposes.

Proposed mechanism Preliminary mechanism

Not shown.

A proposed mechanism does not show that the effect happens in people.

See the Safety tab: this page does not advise swallowing copaiba oil or using it undiluted on skin. The trial tested a 1.0% oil in a gel, not oil on its own.

20

Psoriasis (three patients, oleoresin by mouth or on skin)

Not enough evidence

In a very small report, three people with long-term psoriasis got better in redness, thickness and scaling after taking or applying copaiba oleoresin. There was no comparison group, so this cannot show that the oleoresin works.

1 studiesNot covered. This page gives no amounts and no ways of using the oil.

Studies, doses and limits

What the trials found

A preliminary report of three patients with chronic psoriasis, no control group.

Results

The authors report significant improvement in erythema, skin thickness and scaliness in all three; no numbers are given in the abstract.

Effect sizes as reported

None given in the abstract.

Why this rating

Three people, no control, no blinding, no numbers. It is an idea to test, not evidence.

Form and dose studied

Not covered. This page gives no amounts and no ways of using the oil.

Who was studied

Three adults with chronic psoriasis.

Limits

No control group; tiny; route of use (mouth or skin) varied; not repeated.

Why researchers looked

Lab work showed an extract calming inflammatory signals in cells, so the authors tried it in a few patients.

Traditional use

Described by the authors as a folk remedy for several inflammatory diseases.

Proposed mechanism Preliminary mechanism

In human monocyte cells in dishes, a purified fraction lowered release of IL-1 beta, IL-6 and TNF alpha and blocked NF-kB entering the nucleus. This is lab evidence only.

A proposed mechanism does not show that the effect happens in people.

Taking oleoresin by mouth is not advised on this page. Psoriasis needs a doctor, not a home oil.

10

Tooth sensitivity after bleaching (copaiba gel applied by a dentist)

Low certainty

In one trial of 75 volunteers having teeth bleached, a copaiba oil gel kept sensitivity low, about the same as a standard desensitizing gel, while sensitivity rose in the placebo group. Bleaching worked equally well in all groups.

1 studiesNot covered. This page gives no amounts and no ways of using the oil.

Studies, doses and limits

What the trials found

A randomized clinical trial in Brazil: 75 volunteers in three groups of 25 (placebo gel, 5% potassium nitrate with 2% sodium fluoride gel, copaiba oil gel), three bleaching sessions with 35% hydrogen peroxide, sensitivity scored on a visual scale for 21 days.

Results

The copaiba and potassium nitrate plus fluoride groups had the lowest sensitivity with no significant difference between them. Placebo sensitivity rose after the last session (p = 0.035). Tooth colour change was the same in all groups (p = 0.725).

Effect sizes as reported

p-values only in the abstract.

Why this rating

A randomized, placebo- and active-controlled trial, but a single small trial of one experimental gel; the abstract gives no score values.

Form and dose studied

Not covered. This page gives no amounts and no ways of using the oil.

Who was studied

Healthy volunteers having in-office tooth bleaching.

Limits

One trial; short; one gel; results do not apply to other copaiba products.

Why researchers looked

Copaiba is traditionally described as anti-inflammatory, so dental researchers tried it for the sensitivity that bleaching can cause.

Traditional use

Not applicable. No traditional use for tooth sensitivity was found in the papers read.

Proposed mechanism Preliminary mechanism

Not established in the paper.

A proposed mechanism does not show that the effect happens in people.

This was an experimental dental gel used in a clinic, not a retail oil. See the Safety tab: this page does not advise swallowing copaiba oil or using it undiluted on skin.

11

Anti-inflammatory, germ-killing and healing effects in dishes and animals

Very low certainty

Most copaiba research is done in dishes and animals. Reviews say antimicrobial and anti-inflammatory activity is studied most, with antioxidant and healing effects also reported. Reviewers call for human studies.

3 studiesNot covered. This page gives no amounts and no ways of using the oil.

Studies, doses and limits

What the trials found

No human trial of these lab effects was found beyond the small trials on the other tab.

Results

A review of 232 research records found in vitro (dish) work the most common study type, mainly from Brazil, with Copaifera reticulata the most studied species followed by C. langsdorffii and C. multijuga. A scoping review of 22 topical studies found nine kinds of product and six kinds of therapeutic effect studied, antimicrobial action most often.

Effect sizes as reported

Not applicable (reviews of mostly lab work).

Why this rating

Lab and animal work, and reviews that only map what has been studied. Neither reviewer rates the effect in people.

Form and dose studied

Not covered. This page gives no amounts and no ways of using the oil.

Who was studied

Cells, animals and a few small human studies.

Limits

Reviews do not appraise study quality in the abstracts read; most work is by Brazilian groups; findings vary by species and sample.

Why researchers looked

Copaiba oleoresin is a traditional remedy, so scientists have tested it widely in the lab.

Traditional use

Copaiba oleoresin is a traditional resource of Amazonia; a 2026 review says it has been used since the 16th century as an anti-inflammatory and healing agent in Brazil.

Proposed mechanism Preliminary mechanism

Terpenes in the oleoresin, including beta-caryophyllene and diterpene acids such as copalic acid, are credited in the papers read. In cells, one purified fraction reduced inflammatory messengers and blocked NF-kB (see the psoriasis report). This is laboratory evidence.

A proposed mechanism does not show that the effect happens in people.

Lab and animal results do not show that any copaiba product is safe or works in people.

The evidence

The research centre for Copaiba Oil (Balsam). Every record here was checked against PubMed or the publisher's page; we never list a study we have not verified.

Evidence by outcome

Bars show how many studies we found for each outcome, not how well it works. People are added up across trials only (reviews are not added, to avoid double counting).

How we rate evidence

High certainty

Several well-run trials or reviews agree; further research is unlikely to change the picture much.

Moderate certainty

Good trials point the same way, but some doubt remains.

Low certainty

Small, short or inconsistent trials. The finding could change with better research.

Very low certainty

Very little or very weak human data. Treat as a possibility only.

Mixed findings

Trials or reviews disagree with each other.

Not enough evidence

Not enough human research to say either way.

Evidence against

Good research found no benefit, or found harm.

We take the reviewers' own risk-of-bias and GRADE statements where they exist, and otherwise judge from study size, design, consistency, directness and whether a product matches what is sold. Many publications do not make evidence high. Method note: We read the abstracts of 14 PubMed papers and records, plus the FDA, Poison Control and Tisserand Institute pages; we checked plant names in GBIF and compounds in PubChem. We did not check LiverTox, EMA, NCCIH, LactMed or IFRA.

Copaifera multijuga oleoresin in a carboxypolymethylene hydrogel, on the wound
oleoresin Not reported here weekly follow-up until healed · vs Plain hydrogel (standard treatment)
The abstract says average healing time across the three groups differed with p > 0.05, that the 2% gel healed faster than the 10% gel (p < 0.05), and that wound size reduction could not be shown to differ. All wounds healed by the end of the study; 47.6% healed by week 2. No local or serious adverse effects were reported. The authors conclude the 2% gel gives faster healing, but the abstract does not clearly show a difference from the plain hydrogel.

Says misuse of essential oils can cause serious poisoning. Pure essential oils are potent, and diluting them in a carrier oil is the best way to avoid a bad reaction from direct skin contact. Stop use and gently wash off if a rash or other skin reaction occurs. Do not use essential oils on damaged skin. Aspirating (breathing into the lungs) a swallowed oil can cause pneumonia. Children have thin skin and immature livers, which may make them more susceptible. Essential oils may interact with medications. Products are not well regulated, so species, concentration and contaminants can be hard to know, and products often contain other oils or alcohol. Allergy is a real possibility; rash is the most common sign, and breathing difficulty is a medical emergency. If you have bottles at home with young children, lock them up out of sight and reach of children and pets. If someone swallows an essential oil, call 1-800-222-1222 (US).

Main points to know 5
  • Do not swallow it, and keep it away from children and pets.. Poison Control says misuse of essential oils can cause serious poisoning, and that a swallowed oil breathed into the lungs can cause pneumonia. The Tisserand Institute says not to swallow essential oils unless a qualified practitioner licensed to prescribe them says so. Copaiba oleoresin is used by mouth in Amazonian folk medicine, and a 2023 review says its toxic effects are little known. No human trial of swallowed copaiba was found. If anyone may have swallowed an essential oil, call poison control (US 1-800-222-1222). Expert statement 15 19 5
  • Skin reactions are possible; never put it on skin undiluted.. A 2026 case report describes contact dermatitis from copaiba balsam in a child that looked like a deep skin infection. Only the title was available to read. The Tisserand Institute says the most common adverse reaction is a skin reaction, mostly from undiluted oil, and that an allergic reaction may mean avoiding that oil for life. Poison Control says to stop use and wash off if a rash appears and not to use essential oils on damaged skin. One hospital trial of an oleoresin hydrogel on wounds reported no local adverse effects. Case report and expert statement 3 19 15 6
  • Liver: one case report with another herb, and little else known.. A 2014 case report describes liver damage in an elderly woman who used herbal products of St John's wort and copaiba, and who recovered after stopping. The authors suspect the combination; copaiba alone was not shown to be the cause. Animal tests of one oleoresin found no toxicity in single-dose and eye tests, but repeated high-strength skin doses changed behaviour and blood measures. A LiverTox entry was not checked. Case report and animal 1 2 5
  • What is in the bottle may not be copaiba: adulteration is common.. Lab papers say copaiba oil-resin has commonly been adulterated with cheaper oils such as soybean oil, often above 50%, and that the oil has not been standardized by industry or regulatory agencies. Poison Control adds that essential oil products are not well regulated, so the species, strength and contaminants can be hard to know. A trial result is only about the oil that was tested. Laboratory and expert statement 13 12 15
  • Pregnancy, breastfeeding, babies, children, pets: no copaiba data.. No study of copaiba in pregnancy, breastfeeding, babies, children, cats or dogs was found in the sources read. Not described is not proof of safety. The Tisserand Institute advises people who are pregnant, or have epilepsy, asthma, a skin condition or take prescribed medicines, to ask a doctor or suitable practitioner before using essential oils.

Overdose, product quality and regulators

Summary. The documented harms are skin reactions (one case report) and the class warnings about swallowing essential oils. A 2023 review says the toxicity of copaiba oils is little known. In one animal study of a different Copaifera species, most acute tests showed no toxicity.

Amounts. No safe amount is established, and this page gives none.

Onset and course. Not described for copaiba.

Repeated use. Human trials read were short; in animals, repeated skin doses of the highest strength changed behaviour and blood measures.

Animal data. Copaifera epunctata oleoresin: acute oral, acute dermal and eye tests showed no toxicity; the repeated-dose skin test at the highest strength changed behaviour and blood measures; the authors conclude low toxicity risk.

Toxic parts. The oleoresin or its distilled oil. The paper read lists beta-caryophyllene as its main compound.

Not read. Tisserand and Young 'Essential Oil Safety', IFRA standards, EU fragrance allergen lists, LiverTox, LactMed, EMA/HMPC, NCCIH, any cat or dog study of copaiba, asthma, epilepsy and hormone studies.

Adulteration with soybean oil has been common. The oil is not standardized by industry or regulators, and products are not well regulated. Copaiba from forest sources contains trace metals and minerals; what the levels mean for users is not stated in the abstract read.

Adulteration with cheaper oils. Two lab papers say copaiba oil-resin has commonly been adulterated with soybean oil, normally above 50%; a screening method could detect gross adulteration but not low levels. Two commercial samples in a 40-sample study lacked most of the characteristic compounds. 13 12

Composition varies by species and origin. Samples grouped by origin, and the main compound differed between studied oils (beta-caryophyllene in one oleoresin, alpha-bergamotene in another volatile fraction, cis-thujopsene in a distilled oil). 12 10 20 2

Metals in the oleoresin. Ten forest samples were tested for 16 elements, including arsenic, cadmium and lead. The abstract gives only an overall range (0.055 mg/kg cadmium to 2355.9 mg/kg calcium) and no safety limits, so no conclusion is drawn. 4

Unregulated products. Species, strength and contaminants are not always known; products may contain other oils or alcohol. 15

  • Trouble breathing, swelling of the face or throat, collapse or hives after any contact or breathing in the oil: call emergency services at once.
  • A child or pet that has swallowed oil or is drooling, vomiting, very sleepy or struggling to breathe: call poison control or a vet at once.
  • A spreading red, hot or blistered rash after the oil touched the skin: stop contact, wash the skin and see a doctor.
  • Oil in the eyes: rinse with plenty of water and get medical help.
  • Yellow skin or eyes, dark urine or belly pain after using herbal products: see a doctor.

Stop using the product and contact a clinician or emergency service. In the US, Poison Control is 1-800-222-1222.

General information only, not medical advice. Ask a clinician or pharmacist before use, especially with medicines, in pregnancy or with a health condition. See the Natural Remedy Safety guide.

Frequently asked questions

Is copaiba oil safe to swallow?

This page does not advise it. Poison Control warns that misuse of essential oils can cause serious poisoning, and the Tisserand Institute says not to swallow them unless advised by a qualified, licensed practitioner. Copaiba oleoresin is used by mouth in Amazonian folk medicine, but a 2023 review says its toxic effects are little known. No human trial of swallowed copaiba was found. If anyone swallows an essential oil, call poison control (US 1-800-222-1222).

15 19 5

Can I put copaiba oil on my skin?

Not undiluted. The Tisserand Institute and Poison Control both warn against undiluted essential oils on skin, and a 2026 case report describes contact dermatitis from copaiba balsam in a child. Stop and wash it off if a rash appears. Ask a pharmacist or dermatologist before using any essential oil product.

19 15 3

What is the difference between copaiba oleoresin and copaiba essential oil?

The oleoresin is the whole sap from the tree: a volatile part plus a heavier resin part with acids such as copalic acid. A steam-distilled essential oil keeps only the volatile part, so its makeup differs. The acne trial used a distilled oil; the skin tear and psoriasis papers used the oleoresin. Retail products can be either, so check the label and ask the seller.

10 20 6

Does copaiba oil help wounds or skin tears?

The evidence is thin. In one trial of 84 older hospital patients, a 2% oleoresin hydrogel healed faster than a 10% one, but the abstract does not clearly show a difference from plain hydrogel. No side effects were reported. That was a medical gel, and it does not show that a bottle of oil heals wounds.

6

Does copaiba oil help acne?

One small placebo-controlled trial from 2012 reports a larger fall in acne area with a 1.0% steam-distilled copaiba oil gel than with placebo gel. The abstract gives no group sizes, and the placebo group improved too. It has not been repeated in our searches, so certainty is very low.

20

Does copaiba help tooth sensitivity?

One trial of 75 volunteers found a copaiba oil gel, applied in a dental clinic after bleaching, kept sensitivity low, about the same as a standard desensitizing gel, while placebo sensitivity rose. It is a single trial of an experimental gel, so certainty is low.

11

Is copaiba oil anti-inflammatory or a pain reliever?

It has a long traditional reputation, and reviews say anti-inflammatory activity is among the most studied effects, mostly in cells and animals. We found no trial of copaiba for pain. In cells, one purified fraction lowered inflammatory messengers. Lab results do not show a benefit in people.

8 10

Is copaiba oil safe in pregnancy, while breastfeeding, or around children and pets?

Unknown. No copaiba-specific data were found. The Tisserand Institute advises people who are pregnant, or have epilepsy, asthma or skin conditions, to ask a doctor first, and Poison Control says children have thin skin and immature livers. Keep oils locked away from children and pets, and call poison control or a vet if one is swallowed.

19 15

Can copaiba cause liver problems?

One 2014 case report describes liver damage in an elderly woman who used St John's wort and copaiba products together; she recovered after stopping. Copaiba alone was not shown to be the cause. A 2023 review says toxicity of copaiba oils is little known. Tell a doctor about yellow skin or eyes, dark urine or belly pain.

1 5

Is the copaiba oil I buy pure?

It may not be. Lab papers say copaiba oil-resin has not been standardized by industry or regulators and has often been adulterated with cheaper oils such as soybean oil, normally above 50%. Poison Control says essential oil products are not well regulated. A trial result applies only to the preparation that was tested.

Which compounds are in copaiba?

Beta-caryophyllene is a main compound in some oleoresins (39.7% in one Copaifera epunctata sample), while one C. langsdorffii volatile fraction was mostly alpha-bergamotene, and a distilled oil in the acne trial was mostly cis-thujopsene. Resin acids such as copalic acid are in the oleoresin. Amounts vary by species and origin, and the research does not show that any single compound causes a benefit or harm.

Is copaiba harvesting good for the forest?

Two papers describe oleoresin tapping as bringing income to local communities and supporting forest conservation. We found no study of how tapping affects the trees, so the sustainability of a given product cannot be judged from this evidence. Ask the seller where and how it was harvested.
