How Do You Extract Essential Oils From Plants?

The use of essential oils has become increasingly popular due to their numerous health benefits. They are derived from plants and have a concentrated aroma that is often used in aromatherapy and other natural therapies. But, how do you extract essential oils from plants? This article will guide you through the process.

What are Essential Oils?

Essential oils are highly concentrated plant extracts that retain the natural smell and flavor, or "essence," of their source. They are extracted from different parts of plants, including the flowers, leaves, bark, stems, roots, and fruits.

Methods of Extracting Essential Oils

There are several methods used to extract essential oils from plants, including distillation, cold pressing, and solvent extraction.


Distillation is the most common method of essential oil extraction. It involves the use of steam to vaporize the plant’s volatile compounds, which then cool down and condense back into liquid form. The resulting liquid contains both the essential oil and the water used in the distillation process. These two components are then separated due to their different densities.

Cold Pressing

Cold pressing, also known as expression or expeller pressing, is primarily used for citrus fruits like oranges and lemons. The rinds of these fruits are mechanically pressed to squeeze out the essential oil. This method maintains the vibrant aroma of the fruit.

Solvent Extraction

Solvent extraction is used when the plant material is too delicate for distillation or cold pressing. In this method, a solvent such as hexane is used to extract the oil. The solvent is then evaporated, leaving behind the essential oil.

How to Use Essential Oils

Once you have extracted the essential oils, they can be used in various ways. They can be diffused into the air using a diffuser, applied topically to the skin, or used in homemade products like candles, soaps, and lotions.

Remember, essential oils are highly concentrated and should always be used with caution. Always dilute them with a carrier oil before applying to the skin, and never ingest essential oils without professional guidance.


In conclusion, extracting essential oils from plants involves various methods including distillation, cold pressing, and solvent extraction. Each method has its own benefits and is suitable for different types of plants. With the right tools and knowledge, you can start making your own essential oils at home.

DIY Essential Oil Extraction

If you're interested in extracting your own essential oils, you can try simple steam distillation at home. Here's a quick guide on how to do it:

Materials Needed

  • A crockpot with a lid
  • Distilled water
  • Plant material (flowers, leaves, etc.)
  • Ice
  • A small glass bowl


  1. Place the plant material in the crockpot and add distilled water. The water should just cover the plants.
  2. Place the small glass bowl in the center of the crockpot. This will collect the essential oil.
  3. Invert the lid of the crockpot and cover. The inverted lid will allow the condensed steam to drip into the glass bowl.
  4. Turn on the crockpot on low heat and let it simmer. As the water heats up, it will create steam that carries the essential oils. The steam will hit the cold lid, condense, and then drip into the glass bowl.
  5. After several hours, turn off the crockpot and let it cool.
  6. The liquid in the small bowl is your essential oil. Be sure to store it in a dark glass bottle away from sunlight.

Final Thoughts

Extracting essential oils from plants can be a rewarding process, allowing you to create personalized scents and therapeutic blends. Remember, safety is crucial when dealing with these potent oils. Always use them responsibly and enjoy the benefits they offer.

The Benefits of Essential Oils

Beyond their delightful aroma, essential oils offer numerous benefits. They have been used for centuries in various cultures for medicinal and health purposes. Here are a few benefits you can enjoy from these plant extracts:

Stress and Anxiety Relief

Certain essential oils like lavender, chamomile, and rose are known for their calming effects. Diffusing these oils or applying them topically (diluted with a carrier oil) can help reduce stress and anxiety.

Sleep Improvement

Essential oils can also help improve sleep quality. Lavender, in particular, is widely used for its sleep-inducing properties. A few drops in your diffuser before bedtime can promote a good night's sleep.

Pain and Inflammation Reduction

Some essential oils, such as eucalyptus and peppermint, have analgesic and anti-inflammatory properties. They can be used to alleviate headaches, muscle pain, and joint inflammation.

Choosing the Right Essential Oil

When it comes to choosing which essential oils to extract from plants, it's important to consider the plant's medicinal properties, the scent you prefer, and the method of extraction suitable for the plant. Always opt for plants that are free from pesticides and other chemicals, especially if you plan on using the oils topically or diffusing them in your home.


Whether you're interested in the therapeutic benefits of essential oils or simply love their natural fragrances, extracting them from plants can be a fascinating process. With patience and practice, you can master the art of essential oil extraction and enjoy the rewards of your very own homemade oils.

Safety Precautions When Using Essential Oils

While essential oils offer numerous benefits, they must be used with caution. Here are some safety guidelines to keep in mind:


Essential oils are highly concentrated and can cause skin irritation or allergic reactions if applied directly. They should always be diluted with a carrier oil, like jojoba or coconut oil, before topical application.


Ingesting essential oils is generally not recommended without the guidance of a healthcare professional. Some oils can be toxic if swallowed.

Pregnancy and Children

Some essential oils may not be safe for pregnant women or children. Always consult with a healthcare professional before using essential oils in these situations.

Storing Essential Oils

Proper storage is crucial to maintain the potency and efficacy of your essential oils. They should be stored in dark glass bottles to protect them from sunlight, which can degrade the oils. Also, store them in a cool, dry place and make sure the cap is tightly sealed to prevent evaporation.


Extracting essential oils from plants can be an exciting and rewarding endeavor. It allows you to explore the therapeutic benefits of various plants and create your own unique oil blends. However, remember to handle and use these potent oils with care to ensure safety.
