Cilantro, also known as coriander in some parts of the world, is more than just a culinary herb. Its vibrant green leaves offer a refreshing burst of flavor, and surprisingly, they can be used to create a potent and aromatic essential oil. While not as widely commercially available as other essential oils, crafting your own cilantro essential oil is a rewarding process, providing a unique addition to your aromatherapy and wellness practices. This comprehensive guide will delve into the process, exploring different methods, safety precautions, and potential uses of this intriguing oil.
Understanding Cilantro Essential Oil
Cilantro essential oil is extracted from the leaves of the Coriandrum sativum plant. It possesses a distinctive aroma, often described as fresh, herbaceous, and slightly citrusy. The oil is rich in various chemical compounds, including linalool, alpha-pinene, and geranyl acetate, which contribute to its potential therapeutic properties.
Unlike other essential oils derived from seeds or resins, cilantro essential oil is obtained solely from the plant’s leaves. This distinction influences the extraction method and the oil’s final composition. Understanding this fundamental aspect is crucial for successfully producing high-quality cilantro essential oil.
The Benefits of Cilantro Essential Oil
Cilantro essential oil, though less common than other essential oils, offers a range of potential benefits, primarily stemming from its key chemical constituents. Linalool, for instance, is known for its calming and relaxing properties, making it a valuable addition to aromatherapy blends designed to reduce stress and anxiety. Alpha-pinene is believed to possess anti-inflammatory and analgesic properties, while geranyl acetate contributes to its pleasant aroma and may offer antioxidant benefits.
While research on cilantro essential oil specifically is ongoing, preliminary studies and anecdotal evidence suggest it may be beneficial for:
- Reducing anxiety and promoting relaxation
- Easing muscle aches and pains
- Supporting digestive health
- Acting as an insect repellent
- Boosting the immune system
It’s crucial to remember that essential oils are highly concentrated substances and should be used with caution. Always dilute cilantro essential oil appropriately before topical application, and consult with a healthcare professional or qualified aromatherapist before using it for therapeutic purposes, especially if you have any underlying health conditions or are pregnant or breastfeeding.
Distinguishing Cilantro Oil from Coriander Oil
It is important to distinguish between cilantro essential oil and coriander essential oil. While both come from the Coriandrum sativum plant, they are extracted from different parts. Cilantro essential oil is derived from the leaves, while coriander essential oil is extracted from the seeds. The resulting oils have distinct chemical compositions and aromas. Coriander seed oil typically has a warmer, spicier, and woodier scent compared to the fresh, herbaceous, and citrusy aroma of cilantro leaf oil.
Understanding this difference is critical when selecting and using these oils for aromatherapy or other purposes. Always check the label carefully to ensure you are using the correct oil for your desired application.
Methods for Making Cilantro Essential Oil
While professional-grade essential oil extraction often involves specialized equipment like steam distillers, it is possible to create a cilantro-infused oil or a rudimentary essential oil at home with readily available materials. Here, we’ll explore two main approaches: infusion and steam distillation (a simplified home version).
Infusion Method: Creating Cilantro-Infused Oil
The infusion method is the simplest way to capture some of the aroma and properties of cilantro in an oil. However, it’s important to understand that this method yields an infused oil, not a true essential oil produced through distillation.
Materials Needed:
- Fresh cilantro leaves, thoroughly washed and dried
- Carrier oil (e.g., olive oil, sunflower oil, grapeseed oil, or sweet almond oil)
- Clean, dry glass jar with a tight-fitting lid
- Cheesecloth or fine-mesh sieve
- Dark glass bottle for storage
Step-by-Step Instructions:
- Prepare the Cilantro: Finely chop the fresh cilantro leaves. The more finely chopped, the better the surface area for infusion. Make sure the leaves are completely dry to prevent mold growth during the infusion process. Moisture is the enemy here.
- Combine Cilantro and Carrier Oil: Fill the clean, dry glass jar about halfway with the chopped cilantro leaves. Pour the carrier oil over the leaves, ensuring they are completely submerged. Leave about an inch of headspace at the top of the jar.
- Infusion Process (Cold Infusion): Seal the jar tightly and place it in a cool, dark place for 4-6 weeks. Shake the jar gently every few days to help release the cilantro’s aroma and properties into the oil.
- Infusion Process (Warm Infusion): Alternatively, for a quicker infusion, you can use a gentle heat method. Place the sealed jar in a warm place, such as a sunny windowsill or a water bath (bain-marie) set at a very low temperature (around 100-120°F or 38-49°C) for a few hours each day, for 1-2 weeks. Monitor the temperature carefully to avoid overheating the oil, as high heat can degrade the oil and the cilantro’s beneficial compounds.
- Strain the Oil: After the infusion period, strain the oil through a cheesecloth or fine-mesh sieve into a clean bowl or container. Squeeze the cheesecloth to extract as much oil as possible from the cilantro leaves.
- Storage: Pour the strained cilantro-infused oil into a dark glass bottle and store it in a cool, dark place. This will help preserve its freshness and potency. Properly stored, cilantro-infused oil can last for several months.
Important Considerations for Infusion:
- Drying is Key: Ensure the cilantro leaves are completely dry to prevent mold growth.
- Quality of Carrier Oil: The quality of the carrier oil will impact the final product. Choose a high-quality, cold-pressed oil.
- Sunlight and Heat: Avoid exposing the oil to direct sunlight or high heat during the infusion process, as this can degrade the oil.
- Shelf Life: Cilantro-infused oil has a shorter shelf life than true essential oil. Observe for any signs of rancidity (off smell) and discard if necessary.
Simplified Steam Distillation Method (Home Version)
While a professional steam distillation setup is complex, a simplified version can be attempted at home. This method aims to extract a small amount of essential oil through steam, though the yield and purity will not match that of professional extraction. Caution: This method involves heat and steam. Exercise extreme caution to avoid burns.
Materials Needed:
- Large stainless steel pot with a lid
- Heat-safe bowl that can fit inside the pot without touching the bottom
- Brick or heat-safe platform to elevate the bowl inside the pot
- Fresh cilantro leaves, coarsely chopped
- Ice packs
- Distilled water
- Small glass container to collect the distillate
- Turkey baster or syringe
Step-by-Step Instructions:
- Setup: Place the brick or heat-safe platform in the center of the large pot. Add distilled water to the pot, ensuring the water level is below the top of the brick or platform. Place the heat-safe bowl on top of the brick or platform. The bowl will collect the distilled liquid.
- Add Cilantro: Place the chopped cilantro leaves around the bowl inside the pot, but not in the bowl. You want the steam to pass through the cilantro.
- Inverted Lid and Ice: Invert the lid of the pot and place it on top, creating a sealed environment. The inverted lid will encourage condensation to drip into the bowl. Place ice packs on top of the inverted lid. The cold temperature will help condense the steam more effectively.
- Heating and Distillation: Slowly heat the pot on a stovetop over low to medium heat. As the water boils, the steam will pass through the cilantro leaves, carrying the essential oil vapors. The steam will then condense on the cold lid and drip into the bowl.
- Collection: Continue the distillation process for 1-2 hours, carefully monitoring the water level in the pot and adding more distilled water as needed to prevent it from running dry. Important: Do not let the pot boil dry.
- Separation (Very Challenging): After the distillation process, carefully turn off the heat and allow the pot to cool completely. Use a turkey baster or syringe to carefully collect the liquid (distillate) from the bowl. This liquid will be a mixture of water and a small amount of cilantro essential oil.
- Separating the Oil (Difficult): Separating the essential oil from the water is very difficult with this method and likely won’t result in a significant amount of pure essential oil. The small amount of oil that is produced is highly likely to remain mixed with the water. Attempting to physically separate small amounts can be done in a separatory funnel, which can be purchased online. Otherwise, you will end up with what is known as a hydrosol, which is aromatic water.
- Storage (Hydrosol): If you cannot separate the oil, store the hydrosol in a dark glass bottle in the refrigerator. Use within a few weeks.
Important Considerations for Simplified Steam Distillation:
- Safety First: This method involves heat and steam. Exercise extreme caution to avoid burns. Wear oven mitts and handle hot components carefully.
- Low Yield: The yield of essential oil using this method will be very small. Do not expect to produce a significant amount of pure essential oil.
- Hydrosol: You are more likely to produce a hydrosol, which is an aromatic water containing a small amount of essential oil. Hydrosols are gentler than essential oils and can be used as facial toners or room sprays.
- Purity: The oil produced using this method will not be as pure as commercially produced essential oil.
- Sanitation: Ensure all equipment is thoroughly cleaned and sanitized before use.

Its aroma is also believed to possess calming and uplifting properties, potentially aiding in stress reduction and mood enhancement. However, it’s crucial to note that more research is needed to definitively confirm all of these benefits.
What are the two primary methods for making cilantro essential oil?
The two most common methods for creating cilantro essential oil are steam distillation and solvent extraction. Steam distillation, considered the gold standard for producing high-quality essential oils, involves passing steam through the cilantro plant material. The steam carries volatile aromatic compounds, which are then condensed and separated, resulting in pure essential oil.
Solvent extraction, on the other hand, uses chemical solvents like hexane to extract the oil from the plant. While this method is often more efficient and can yield a higher volume of oil, it may leave trace amounts of solvent residue in the final product. This residual solvent can be a concern for some users, especially those with sensitivities.
Can I make cilantro essential oil at home without specialized equipment?
While true essential oil extraction typically requires specialized equipment like a still for steam distillation, it is possible to create a cilantro-infused oil at home using a carrier oil. This method, known as infusion, involves steeping fresh cilantro leaves in a carrier oil like olive oil, almond oil, or jojoba oil.
The process involves gently heating the carrier oil and cilantro leaves to allow the oil to absorb the plant’s beneficial compounds and aromatic properties. While the resulting infused oil won’t be as potent or concentrated as true essential oil, it can still provide therapeutic benefits and add a delightful cilantro flavor to culinary creations. It’s important to store this infused oil properly in a cool, dark place to prevent spoilage.
What carrier oils are best to use when diluting cilantro essential oil for topical application?
Choosing the right carrier oil is crucial when diluting cilantro essential oil for topical use, as it can influence the oil’s absorption and overall effectiveness. Popular choices include jojoba oil, which closely mimics the skin’s natural sebum and is easily absorbed. Another excellent option is sweet almond oil, known for its moisturizing properties and suitability for most skin types.
Grapeseed oil is another lightweight option that’s rich in antioxidants and absorbs quickly. For drier skin, avocado oil or coconut oil (fractionated) can provide extra hydration. It’s essential to perform a patch test before applying any diluted essential oil to a larger area of skin to check for any allergic reactions or sensitivities.
How do I properly store cilantro essential oil to maintain its quality?
Proper storage is essential for preserving the quality and potency of cilantro essential oil. The key is to protect it from exposure to light, heat, and air, as these elements can degrade the oil’s beneficial compounds. Always store cilantro essential oil in a dark-colored glass bottle, such as amber or cobalt blue, to shield it from light.
Keep the bottle tightly sealed when not in use to prevent oxidation and evaporation. Store it in a cool, dark place, such as a cabinet or drawer, away from direct sunlight and heat sources like stoves or radiators. Storing your cilantro essential oil properly will help extend its shelf life and ensure that it retains its therapeutic properties for a longer period.
Are there any safety precautions I should take when using cilantro essential oil?
Cilantro essential oil, like all essential oils, should be used with caution and awareness of potential safety concerns. Always dilute cilantro essential oil with a carrier oil before applying it topically, as undiluted essential oils can cause skin irritation or sensitization. A general guideline is to use a 1-3% dilution for adults.
Pregnant and breastfeeding women should consult with a healthcare professional before using cilantro essential oil, as its effects during these periods are not fully known. Keep essential oils out of reach of children and pets. If you experience any adverse reactions, such as skin irritation, nausea, or headache, discontinue use immediately. Always consult with a qualified aromatherapist or healthcare provider for personalized advice.
How can I verify the purity and quality of commercially purchased cilantro essential oil?
Ensuring the purity and quality of commercially purchased cilantro essential oil is paramount for experiencing its potential benefits safely and effectively. Look for reputable brands that provide detailed information about their sourcing, extraction methods, and testing procedures. Companies that offer GC/MS (Gas Chromatography/Mass Spectrometry) reports demonstrate a commitment to transparency and quality control.
These reports analyze the chemical composition of the oil, verifying its purity and identifying any adulterants. Be wary of excessively cheap oils, as they may be diluted with cheaper ingredients or of inferior quality. Reading customer reviews can also provide valuable insights into the oil’s aroma, effectiveness, and overall quality.
