Copaiba (Copaifera officinalis) Oil

Heritage and History

Copaiba (also spelled copaíba) oil comes from the resin of Copaifera trees, a genus in the legume family (Fabaceae) [1] with more than 70 species, most of them in Central and South America; Brazil alone is home to 26 [2]. The trees store an oily resin, called an oleoresin, in their trunks [3], and the name copaiba comes from the Tupi language by way of Portuguese [4].

Copaiba oleoresin has a long history in traditional medicine. Native peoples of the Brazilian Amazon have used it as an anti-inflammatory and applied it to the skin to heal wounds, and sixteenth-century chroniclers of Brazil's colonization recorded these uses [2].

Today, the essential oil distilled from copaiba resin is valued in perfumery and cosmetics [3] for its soft, woody aroma.

Cultivation and Regional Origins

Copaiba trees grow wild across tropical South America. Copaifera officinalis, the species whose name is used for copaiba oil in cosmetics, is native to Venezuela, northeastern Brazil and Bolivia [1], and Copaifera martii is native to northern and northeastern Brazil [5]; both grow mainly in seasonally dry tropical regions [1, 5].

The resin is harvested without cutting down the tree. Harvesters drill a small hole, about 2 cm wide, into the trunk, collect the resin through a pipe and then seal the hole with wood; in the past, trees were felled or cut open with axes or chainsaws [6]. Not every tree yields resin: in one Amazon study, fewer than half of the trees produced more than a milliliter at the first harvest, and for some species even a year or more between harvests may be too short [6].

Resin from several trees is often combined [2], and commercial copaiba is not always identified to species [3]. The essential oil is then obtained by steam distillation of the resin, which carries off its lighter, aromatic compounds.

Chemistry of Copaiba Oil

Copaiba oleoresin is made of two parts: heavier, non-volatile diterpene acids and a lighter, volatile fraction of sesquiterpenes [2]. Distillation captures the volatile fraction [3], so copaiba essential oil consists mainly of sesquiterpene hydrocarbons and is often dominated by beta-caryophyllene [2]. Key chemical constituents include:

• Beta-caryophyllene (typically 40–70%): The main component, also found in the essential oils of many spice and food plants and in cannabis [7]. It gives copaiba oil much of its warm, woody, slightly spicy character.

• Alpha-humulene (up to about 11%) and alpha-copaene (typically 2–10%): Sesquiterpenes commonly found among the major components of copaiba resin [2].

• Germacrene D (up to about 10%), trans-alpha-bergamotene (up to about 14%) and beta-bisabolene (up to about 12%): Other sesquiterpenes that round out the oil's aroma.

Composition figures are typical specification ranges for commercial copaiba essential oil; exact values vary from batch to batch.

Benefits for Skin and Hair

For Skin:

• Warm, Woody Aroma: Copaiba oil's soft, woody scent blends well with other woody oils such as cedarwood, sandalwood and vetiver, making it a natural choice for scenting body oils.

• Soothing Ritual: Massaged into the skin in a diluted blend, copaiba's warm scent makes for a calming, grounding self-care ritual.

• Comfort for Stressed-Looking Skin: Diluted in a carrier oil, copaiba is used in skin care blends designed to help skin look calm and comfortable.

For Hair:

• Scalp Massage Blends: Diluted in a carrier oil, copaiba oil adds a warm, grounding scent to scalp massage blends.

• Natural Fragrance for Hair Oils: A few drops of a diluted copaiba blend leave hair with a subtle, woody scent.

How It Works

Most of the published science on copaiba comes from laboratory and animal studies, and much of it tested the whole oleoresin rather than the distilled essential oil. Here is what that research found, and what it does and doesn't tell us.

Beta-Caryophyllene and the CB2 Receptor: Beta-caryophyllene binds selectively to CB2, one of the body's cannabinoid receptors. In mice given beta-caryophyllene by mouth, it reduced inflammation, and the effect disappeared in mice lacking CB2 receptors [7]. These results come from oral doses in animals, not from copaiba oil applied to skin.

Anti-Inflammatory Research: Several copaiba oleoresins have shown anti-inflammatory activity in laboratory and animal studies [2], including tests in rats and mice [3]. The effect probably comes from several compounds working together rather than from any single one [3].

Antibacterial Research: In laboratory tests, copaiba oleoresins from three species, including Copaifera officinalis and Copaifera martii, killed Gram-positive bacteria such as Staphylococcus aureus but had no effect on Gram-negative bacteria or yeasts [8].

Wound Healing: Laboratory studies of copaiba and wound healing are mixed, with some supporting its traditional use and others finding delayed healing [3].

Skin Sensitivity: Like several other fragrance terpenes, beta-caryophyllene is not itself allergenic but readily forms allergenic compounds when exposed to air. In a European study of patients with dermatitis, about 0.5% reacted to oxidized caryophyllene [9].

Allergen Information

Food allergens: Copaiba is not one of the nine major food allergens recognized by the U.S. Food and Drug Administration (milk, eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat, soybeans and sesame) [10]. It comes from the legume family (Fabaceae), which also includes peanuts and soybeans; we have not found evidence that people with peanut or soy allergy react to copaiba oil.

Fragrance allergens: Beta-caryophyllene, copaiba oil’s main component, is on the European Union’s list of fragrance allergens that must be named on cosmetic labels [11].

Reported reactions: Beta-caryophyllene readily forms allergenic compounds when exposed to air; in a European study of patients with dermatitis, about 0.5% reacted to oxidized caryophyllene [9]. Store copaiba oil tightly closed, away from heat and light.

Patch test: Dilute essential oils before applying them to the skin. As with any new skincare product, try a small amount of the diluted oil on your inner arm and wait 24 hours before wider use. If you have a known allergy, ask your doctor before using a new product.

Conclusion

Copaiba (Copaifera officinalis) oil is a warm, woody essential oil distilled from a resin that Amazonian peoples have used on the skin for centuries. Rich in beta-caryophyllene, it adds a soft, grounding scent to skin and hair care, while laboratory research continues to explore the compounds behind its traditional reputation.

Like other essential oils, copaiba oil should be diluted before use and may cause skin sensitivity in some people; patch test before first use. Store it tightly closed, away from heat and light, because oxidized oil is more likely to cause skin reactions [9]. Do not swallow copaiba oil; high doses taken by mouth can cause side effects [2].
