In its most basic sense, essential oils are plant extracts. They are highly concentrated oils extracted from the leaves, flowers, stems, roots, bark, or other parts of plants. They are highly concentrated and potent, with a strong aroma and flavor that is characteristic of the plant from which they are extracted. That is why they are called “essential oils,” because they contain the “essence,” which is the aromatic and flavor components of the plant from which they are extracted.

Essential oils have been used for centuries for their wide range of medicinal, health, and therapeutic benefits. Their antibacterial, antifungal and antiviral properties make them a useful and versatile product in your medicine cabinet.

Essential oils are commonly used in aromatherapy, which uses scents to promote relaxation, reduce stress, and improve overall well-being. They can also be used topically to improve the health and appearance of the skin or ingested in small amounts for their potential health benefits.

Benefits of Essential Oils

Here’s a look at some of the common health benefits that essential oils have been used to offer:

1. Reduces stress and anxiety

Perhaps one of the most popular benefits of essential oils is their ability to reduce stress and anxiety. Different essential oils have different scents, and many are believed to be particularly effective at promoting relaxation and reducing anxiety. Some come with sedative properties that can induce a calm, peaceful, relaxed, and uplifting feeling.

Some of the best essential oils for stress and anxiety include chamomile, bergamot, orange, rose, ylang-ylang, vetiver, and frankincense.

2. Alleviates headaches and migraines

Essential oils can work as natural migraine and headache relievers because they can effectively treat the trigger and address the root of the problem instead of masking it. Some essential oils reduce stress and improve circulation – all of which can be major causes of headaches and migraines.

Lavender is popular for treating headache pain, as it can be relaxing and calming. Other essential oils that can relieve headaches include eucalyptus (relieves sinus pressure that causes headaches), peppermint (offers a cooling effect and stimulates blood flow), and rosemary (promotes circulation, reduces inflammation, and gives a calming effect).

3. Aids in sleep and insomnia

Some essential oils offer sedative properties, which can be helpful for people who have trouble falling asleep or getting through the night. Among all essential oils, lavender is best known as an effective sleep aid because of its ability to calm and relax a person through its scent.

Smelling lavender oil’s relaxing fragrance has been shown to improve sleep quality. It’s tested in women after childbirth, patients with heart disease, and older adults living with dementia – all of which are types of people who usually experience low-quality sleep.

Some of the best essential oils for your immunity include oregano, ginger, lemon, myrrh, frankincense, eucalyptus, peppermint, and cinnamon.

How to Use Essential Oils

You can’t reap essential oils’ benefits if you don’t know how to use them. Aromatherapy is a popular use for essential oils, but there is more to them. Here are the different ways you can use essential oils:

1. Diffusion

Aromatherapy is the practice of using scents to promote relaxation and reduce stress, and a type of aromatherapy is diffusing essential oils. Using a diffuser, essential oils spread their aroma in the room. This device disperses tiny particles of the essential oil so you can breathe them in.

Popular types of essential oil diffusers include:

  • Electric diffusers
  • Ceramic diffusers
  • Candles
  • Lamp rings
  • Reed diffuser
  • Ultrasonic diffusers

Whatever diffuser you choose to use, avoid direct contact with the essential oils and dilute it first. Follow the manufacturer’s instructions in a diffuser for the proper oil-to-water ratio.

2. Dry evaporation

If you don’t want to use a diffuser, you can try dry evaporation – although the scent won’t probably spread as a diffuser can. This method requires a dry material like a cotton ball or fabric. Add a few drops of essential oil to the dry material and smell the aroma as it disperses.

You can add the material to the vents in your house, car, pillowcase, or shirt collar.

3. Inhalation

Inhaling essential oils can be an effective way to support respiratory health. Essential oils can be added to a bowl of hot water, and the steam can be inhaled or added to a vaporizer or humidifier. Eucalyptus and peppermint oils are particularly effective at improving respiratory function.

4. Topical use

You can also use essential oils for skin care and massage in different ways, as they can be applied topically to the skin for various purposes. Dilute them to carrier oils, such as coconut or jojoba oil, to use as a massage oil. Check for recipes online to make a blend. Focus on rubbing the essential oil blend in tightness, muscular pain, and tension areas. You can also gently rub it to pressure points like wrists, temples, and third eye.

Another option is to add essential oils to your favorite cosmetic products, like serums and toners. But always make sure to dilute the essential oil in a carrier oil first, and do not add too much oil.

If you want to create an essential oil blend for topical use, it’s best to store it in a small rollerball bottle so you can easily apply it to your skin.

5. Bath and shower use

While you may not want to store essential oils in the bathroom because the heat and humidity may affect their quality, you can find a lot of uses for them there. You can add a few drops of essential oils to your shampoo, body wash, or conditioner.

To inhale essential oils during your shower, add a few drops on the shower walls or a few drops of diluted oils to a warm washcloth you can use to exfoliate your skin. During baths, you may also choose to use an essential oil bath salt or a bubble bath product with an essential oil ingredient.

6. Household use

Essential oils can be used in various ways around the home. They can be added to natural cleaning solutions to add a pleasant scent and boost their cleaning power. Some essential oils, such as lemon and grapefruit oil, are believed to have disinfectant properties that can help kill germs and bacteria.

You can find many DIY recipes for household cleaners that use essential oils for their scent and antibacterial properties.

7. Ingestion

Some essential oils can be ingested in small amounts for their potential health benefits. Some oils, such as peppermint and ginger, are believed to aid digestion and reduce nausea. It’s important to note that not all essential oils are safe for ingestion, and they should only be used under the instruction of a trained herbalist.

However, a lot of experts advise using essential oils this way. Because they are so potent, they may be harmful as you take in a lot of plant material without realizing it. Some oils in certain amounts can even burn the mouth’s mucosal lining, so follow directions closely.
