Making turmeric oil at home is a simple process of slowly infusing a carrier oil with turmeric over low heat for two to three hours. The result is a golden, aromatic oil you can use for skincare, massage, or as a base for homemade beauty products. There are a few different methods depending on your equipment and how much time you have.
What Turmeric Oil Actually Is
It helps to know that “turmeric oil” can mean two different things. True turmeric essential oil is produced through industrial steam distillation, a process that requires specialized equipment, hours of pressurized steam, and yields less than 1% oil by weight from fresh rhizomes. That’s not something you can do in a kitchen.
What you can make at home is a turmeric-infused oil: a carrier oil (like coconut, jojoba, or olive oil) that has absorbed turmeric’s active compounds through gentle heating. This infused oil picks up curcumin (the pigment responsible for turmeric’s color and many of its skin benefits) along with aromatic compounds called turmerones. Curcumin is highly fat-soluble and barely dissolves in water, which is exactly why oil is such an effective medium for extracting it.
Choosing Your Ingredients
Dried Powder vs. Fresh Root
Dried turmeric powder is the better choice for infusing oil. Fresh turmeric root is 80 to 90 percent water, so you get far less curcumin from the same amount. Drying concentrates the active compounds significantly. Fresh root also introduces moisture into your oil, which shortens its shelf life and can encourage bacterial growth. If you do use fresh root, slice it thinly and let it dry completely before infusing.
Picking a Carrier Oil
Jojoba oil works well for skincare because it closely mimics the skin’s natural oils and resists going rancid. Coconut oil is another popular choice, especially if you plan to use the finished product on hair or body. For a more affordable option, olive oil and canola oil are solid picks. Both contain fewer of the fatty acids that oxidize quickly, so they stay fresh longer than oils like sunflower or grapeseed.
Stovetop Infusion Method
This is the most common approach and produces a usable oil in a single afternoon.
- Ratio: 1 tablespoon of turmeric powder to 2 ounces of carrier oil. You can scale this up proportionally.
- Combine: Add the turmeric and oil to a small saucepan or double boiler.
- Heat: Turn the burner to its lowest setting. You want the oil warm, not simmering. If you see bubbles or smoke, it’s too hot.
- Infuse: Let the mixture heat gently for 2 to 3 hours, stirring occasionally. The oil will deepen to a rich golden or orange color as the curcumin dissolves into the fat.
- Strain: Once cooled slightly, pour the oil through a fine mesh strainer lined with cheesecloth or a coffee filter into a clean glass jar. Squeeze the cheesecloth to get every drop. Discard the spent powder.
A double boiler (or a glass bowl set over a pot of simmering water) gives you more temperature control and reduces the risk of scorching. This is worth the extra setup if you’re making a larger batch.
Slow Cooker Method
If you’d rather not babysit a stovetop, a slow cooker set to its “warm” setting works perfectly. Use the same 1 tablespoon to 2 ounces ratio, combine everything in the slow cooker, and let it go for 2 to 3 hours. Some people leave it longer, up to 4 or 5 hours, for a more concentrated infusion. The low, steady heat of a slow cooker is forgiving and nearly eliminates the risk of overheating.
Cold Infusion (No Heat)
You can also skip heat entirely. Combine the turmeric powder and carrier oil in a sealed glass jar, shake well, and store it in a cool, dark place for one to two weeks. Shake the jar once a day to redistribute the powder. This method extracts less curcumin than heat infusion, but it preserves more of the delicate aromatic compounds that break down at higher temperatures. Strain through cheesecloth when the infusion period is done.
Storage and Shelf Life
Homemade infused oils need proper storage to stay safe and effective. Oregon State University’s food safety guidelines recommend refrigerating homemade herb and vegetable oils and using them within four days, or freezing them for longer storage. This applies most strictly when fresh plant material is involved, since moisture creates conditions for bacterial growth.
Because you’re using dried turmeric powder (no moisture), your infused oil will last longer than a fresh herb oil. Stored in a sealed glass jar in the refrigerator, a well-strained turmeric oil typically stays good for several weeks to a couple of months. Label the jar with the date you made it. If the oil develops an off smell or changes color dramatically, discard it. Keeping it in a dark bottle or away from light slows oxidation.
Using Turmeric Oil on Skin
A turmeric-infused carrier oil is already diluted, so it’s generally safe to apply directly to skin. You can use it as a facial oil, body moisturizer, or massage oil. Start by testing a small amount on the inside of your wrist and waiting 24 hours to check for any reaction.
The biggest practical concern is staining. Curcumin is an intense yellow pigment, and it will temporarily tint your skin. To minimize this, use less turmeric in your infusion (try half the standard ratio for facial products), apply only a thin layer, and keep it on for 10 to 15 minutes before wiping off any excess. Rinsing with micellar water or a gentle toner afterward removes residual yellow tint. Kasturi turmeric, a variety sold specifically for cosmetic use, is a naturally non-staining alternative you can substitute in any of the methods above.
Your hands and any utensils will also turn yellow during preparation. Wearing gloves while mixing and straining saves cleanup time. For countertops, a paste of baking soda and water usually lifts turmeric stains.
Using Turmeric Oil in Food
If you’ve made your infusion with a food-grade oil like olive or coconut, you can use it in cooking. It works well drizzled over roasted vegetables, stirred into rice, or whisked into salad dressings. The fat in the oil actually improves your body’s ability to absorb curcumin, since the compound is nearly insoluble in water (only about 11 nanograms per milliliter dissolves in plain water) but readily dissolves in fat. Pairing turmeric oil with black pepper further increases absorption, as a compound in pepper slows the breakdown of curcumin in your digestive system.
Tips for a Stronger Infusion
If your first batch comes out lighter than expected, there are a few adjustments to try. Increase the ratio of turmeric to oil, going up to 2 tablespoons per 2 ounces. Extend the heating time to the full 3 hours. Use high-quality turmeric powder with a vivid orange color, which generally indicates higher curcumin content. Stale or pale-yellow powder has likely lost potency. You can also run a second infusion: strain out the spent turmeric, add fresh powder to the already-infused oil, and heat again for another round of extraction.
