Turning raw frankincense resin into oil at home is entirely possible, and the method you choose depends on what kind of oil you want. True essential oil requires steam distillation or hydrodistillation, which involves heating water and resin so that volatile aromatic compounds evaporate, travel through a condenser, and separate into a concentrated oil. A simpler approach, resin-infused oil, involves soaking crushed resin in a carrier oil over days or weeks. Both produce useful products, but they are chemically and practically very different.
Essential Oil Versus Infused Oil
Before you start, it helps to know which product you are actually after, because the two get conflated constantly online. Essential oil is a concentrated extract of the volatile compounds in frankincense resin, produced exclusively by distillation. It contains no carrier fat and is potent enough to irritate skin if applied undiluted. Infused oil (sometimes called a macerated oil) is a carrier oil like jojoba or olive oil that has absorbed some of the resin’s aromatic and soluble compounds through prolonged contact. It is milder, easier to make, and can go straight onto skin without further dilution.
If your goal is aromatherapy, diffusing, or blending into skincare at specific concentrations, you want the essential oil, and that means distillation. If you want a fragrant body oil or massage oil and prefer a lower-effort process, infusion will serve you well. The rest of this article walks through both paths.
Picking the Right Resin
Frankincense resin comes from several Boswellia species, and the one you choose shapes the aroma and chemistry of the finished oil. The four species you are most likely to encounter commercially are Boswellia sacra (also sold as B. carterii), B. serrata, B. papyrifera, and B. frereana. A comparative chemical analysis of these four species identified over 200 distinct volatile compounds across them, with each species producing a clearly distinguishable chemical profile.1PubMed. Frankincense Revisited, Part I: Comparative Analysis of Volatiles in Commercially Relevant Boswellia Species In practical terms:
- B. sacra / carterii: The most widely used for essential oil production. It tends to produce a warm, resinous, slightly sweet aroma and is the species most commonly studied in frankincense research.
- B. serrata: Native to India, often available in bulk at lower prices. Its profile leans more woody and earthy.
- B. frereana: Sometimes called “Maydi,” prized for its clean, citrusy scent. It produces a lighter oil but the resin can be harder to source.
- B. papyrifera: Found primarily in the Horn of Africa. It has a sharper, more peppery character.
For a first home distillation, B. sacra or B. serrata are the most practical choices because they are widely available and well-documented. Buy resin that looks fresh: pieces should be semi-translucent or milky, not dark brown or powdery. Dusty, crumbled resin may have lost some volatile compounds to evaporation before you even begin.
How Hydrodistillation Works at Home
The standard method for extracting frankincense essential oil is hydrodistillation, the same basic process used for centuries to extract essential oils from plant material.2Comptes Rendus Chimie. Parameter optimization in microwave-assisted distillation of frankincense essential oil In a commercial setting, this is done in large copper or stainless steel stills. At home, you have two realistic options: a purpose-built countertop distillation kit (sold online for around $50 to $200) or a DIY setup using a large stockpot, a domed lid, ice, and a collection bowl.
Using a Countertop Still
Small copper or stainless steel distillation units designed for home essential oil extraction typically include a boiler pot, a column, a condenser coil, and a collection flask. To use one with frankincense resin, you crush or grind the resin into small pieces (a mortar and pestle or a freezer-and-hammer approach both work), add it to the boiler pot with water, and heat the mixture. As steam passes through and around the resin, it carries volatile compounds upward through the column and into the condenser, where cold water cools the vapor back into liquid. The liquid that collects in the flask separates into two layers: a thin layer of essential oil floating on top of a larger volume of hydrosol (aromatic water). You skim or pipette off the oil.
The Stockpot Method
If you do not have a dedicated still, a large stockpot with an inverted lid can serve as a crude but functional substitute. Place crushed resin and water in the pot, set a heat-safe collection bowl in the center (floating on the water or propped on a rack above it), and invert the pot lid so it domes downward. Place ice on top of the inverted lid. As the water heats, steam carrying volatile compounds rises, hits the cold underside of the lid, condenses, and drips down into the collection bowl. The resulting liquid is mostly hydrosol with some essential oil mixed in. Separation is trickier here because you collect far less oil relative to water, so you will need a separating funnel or careful pipetting.
Either way, the underlying chemistry is the same: heat drives volatile molecules out of the resin, steam carries them, and cooling condenses them back into liquid form.
Temperature, Timing, and Yield
Getting the details right matters more than you might expect. In a laboratory study of B. sacra hydrodistillation, researchers collected oil fractions at different temperatures and time windows. Early fractions were collected during the first two hours at 78°C, while later fractions came at the 8-to-12-hour mark, with some runs conducted at 100°C.3PubMed Central. Frankincense essential oil prepared from hydrodistillation of Boswellia sacra gum resins induces human pancreatic cancer cell death in cultures and in a xenograft murine model The chemical composition of the oil shifted depending on when it was collected, meaning the first oil off the still smells different from the last.
For a home distiller, the practical takeaway is that longer runs produce more oil and a more complete aromatic profile. Studies on frankincense steam distillation have confirmed that the longer the distillation period, the higher the total oil yield, and that powdering the resin before distilling improves extraction compared to using whole chunks.4International Journal of Trend in Research and Development. Extraction of Essential Oil from Frankincense Using Steam Distillation Grinding increases the surface area exposed to steam, letting more volatile compounds escape.
As for how much oil you can expect, frankincense resin contains roughly 5 to 9 percent essential oil by weight.4International Journal of Trend in Research and Development. Extraction of Essential Oil from Frankincense Using Steam Distillation In practice, a home setup will not capture all of it. Incomplete condensation, oil left clinging to surfaces, and less efficient steam contact all reduce your yield. Starting with 100 grams of resin, you might realistically collect 2 to 5 milliliters of essential oil over several hours of distillation. That is not much, but a little goes a long way with essential oils.
Temperature control is also worth paying attention to. A gentle simmer is better than a rolling boil. Aggressive boiling can carry unwanted heavier compounds into the distillate, muddy the aroma, and push water into the collection vessel faster than the condenser can handle. If you are using a stockpot, keep the heat at medium-low once steam starts rising. If you are using a dedicated still, follow the manufacturer’s guidance, but most work best with steady, moderate heat.
Making a Resin-Infused Oil Instead
If distillation sounds like more trouble than it is worth for your purposes, a resin-infused carrier oil is a genuine alternative. It will not be an essential oil, but it will smell like frankincense and deliver some of the resin’s soluble compounds into a form you can use directly on skin.
The process is straightforward. Crush your resin into small pieces or a coarse powder. Place it in a clean glass jar and cover it with a carrier oil of your choice. Jojoba is popular because it has a long shelf life and is chemically stable. Olive oil works but has a stronger scent that can compete with the frankincense. Use a ratio of roughly one part resin to four or five parts oil by volume. Seal the jar and let it sit in a warm, dark place for two to six weeks, shaking it every few days. A sunny windowsill speeds things up but risks degrading some compounds with UV exposure, so indirect warmth is better. After steeping, strain out the resin pieces through cheesecloth. The resulting oil will have a mild to moderate frankincense aroma and a slightly thicker texture than the original carrier.
A faster warm infusion method involves placing the jar in a pot of water kept at about 50 to 60°C for several hours, essentially a double-boiler approach. This accelerates the transfer of aromatic and resinous compounds into the oil. You will not extract the most volatile terpenes this way (those need the higher temperatures and steam of distillation), but you will get a fragrant, usable oil in a single afternoon.
What Is Actually in the Oil
Frankincense essential oil is a complex mixture of terpenes and other volatile organic compounds. The specific blend depends on the species, the resin’s freshness, and the distillation conditions, but certain compounds show up consistently. Alpha-pinene is one of the most abundant, giving the oil its sharp, piney top note. Linalool contributes a floral sweetness. Research on frankincense oil has identified alpha-pinene, linalool, and 1-octanol among the components and found that these three compounds contribute to the oil’s topical anti-inflammatory effects, reducing swelling in laboratory models.5Journal of Ethnopharmacology. α-Pinene, linalool, and 1-octanol contribute to the topical anti-inflammatory and analgesic activities of frankincense by inhibiting COX-2
For the home distiller, the practical relevance is this: the early fractions of your distillation will be richer in lighter, more volatile terpenes like alpha-pinene, while the later fractions pick up heavier, warmer compounds. If you run your still long enough and collect everything together, you get a balanced oil. If you stop early, your oil will lean sharper and more citrusy. Neither is wrong, just different.
How Home-Distilled Oil Compares to Store-Bought
A fair question is whether home distillation produces anything comparable to commercial frankincense essential oil. A study comparing lab-distilled Boswellia carteri oil against twenty-one commercial samples found meaningful variation among the commercial oils themselves, with some showing signs of adulteration or compositional inconsistency.6PubMed Central. Comparison of Volatile Constituents Present in Commercial and Lab-Distilled Frankincense (Boswellia carteri) Essential Oils for Authentication Another analysis of twenty commercial frankincense oils found significant variation in their chemical profiles.7South African Journal of Botany. Volatile composition and antimicrobial activity of twenty commercial frankincense essential oil samples
The takeaway is encouraging for home distillers: the “standard” for commercial frankincense oil is itself a moving target. Quality varies widely from brand to brand. A carefully done home distillation using good resin can produce oil that falls well within the range of what is sold commercially. Where home oil typically falls short is in batch-to-batch consistency (commercial distillers control variables more precisely) and in volume (you will produce milliliters, not bottles). But for personal use, the quality gap is smaller than you might assume.
Storing Your Finished Oil
Essential oils degrade over time, and the three main enemies are heat, light, and oxygen.8Comprehensive Reviews in Food Science and Food Safety. Stability of Essential Oils: A Review The lighter, more volatile compounds in your frankincense oil, including many of the terpenes that give it its distinctive top notes, are the most susceptible to breaking down. Research on essential oil storage has shown a consistent decline in the concentration of lower-molecular-weight compounds over time, especially at room temperature, driven by evaporation and oxidation of their reactive chemical structures.9Scientific Reports. Preservation of essential oil quality in endangered Ziziphora tenuior L. under different storage conditions
To maximize shelf life, store your oil in small, dark glass bottles (amber or cobalt blue), filled as full as possible to minimize the air space above the liquid. Keep the bottles in a cool, dark place. A refrigerator is ideal. This will not make your oil last forever, but it slows the oxidation process considerably. Expect well-stored frankincense essential oil to retain its aroma and potency for at least a year or two; poorly stored oil can go flat and develop off-notes within months.
Infused oils have a shorter shelf life because the carrier oil itself can go rancid. Jojoba-based infusions hold up the longest, sometimes two years or more when refrigerated. Olive oil infusions should be used within six months to a year.
Safety and Practical Cautions
Distillation involves sustained heat and steam, so basic kitchen safety applies. Keep a close eye on your water level during long runs; if the pot boils dry with resin in it, you will get scorched resin and potentially noxious smoke instead of essential oil. Replenish water as needed, using a kettle of already-hot water so you do not shock the system with cold water and interrupt the steam flow.
Essential oil from any distillation should be diluted before applying to skin, typically to about 1 to 3 percent in a carrier oil for adults. Undiluted essential oil can cause contact irritation or sensitization. Pregnant women, young children, and people with sensitive skin should use lower concentrations or consult a healthcare provider.
One common mistake among first-time distillers is expecting the oil to smell exactly like the raw resin. It will not. Burning frankincense resin on charcoal releases a different set of compounds than steam distillation does, and some of the heavier resinous molecules that give frankincense incense its deep, churchy character do not come over in the steam. Your distilled oil will smell brighter, sharper, and more terpenic than the burning resin. That is normal.
Sourcing Resin Responsibly
Frankincense trees face real conservation pressures. Overharvesting, habitat loss, and climate stress threaten several Boswellia species, and the question of how to regulate the trade has become contentious. A proposal to list Boswellia species under CITES Appendix II, which would require exporting countries to issue permits certifying that harvests are legal and sustainable, has been debated, though researchers have pointed out that such listing may create unintended complications for communities that depend on the resin trade.10Forest Policy and Economics. Good intentions meet complex realities: CITES listing of diverse frankincense (Boswellia species) might do more harm than good
As a buyer, you can support better practices by purchasing from vendors who identify the species and country of origin, who can describe their supply chain, and who sell resin rather than anonymously blended oils. Cooperatives in Somaliland, Oman, and Ethiopia increasingly market directly to consumers. Paying a fair price for quality resin is not just ethical; it also tends to mean fresher, higher-quality starting material for your distillation, which translates directly into better oil.
Improving Your Results Over Time
Home distillation is as much craft as chemistry. Your first batch will likely be modest in yield and rough around the edges. Each run teaches you something: how fast to heat, when to add more water, how to position the condenser for maximum cooling, and how finely to grind the resin. Research on essential oil distillation more broadly has demonstrated that iterative refinement of processing parameters can substantially improve both yield and chemical quality over successive batches.11PLOS ONE. Distillation of essential oils: An innovative technological approach focused on productivity, quality and sustainability
Keep simple notes on each run: how much resin you used, the grind size, how long you distilled, the heat level, and how much oil you collected. After three or four batches, patterns emerge. You might notice that grinding the resin finer and running the still an extra hour doubles your yield, or that a particular resin from a particular supplier gives a richer aroma. That kind of hands-on iteration is where home distillation becomes genuinely rewarding, because the product improves in ways you can smell and measure.
