The Top 12 Things You Need to Know About Essential Oils (2024)

Are you looking for natural ways to support your health, wellness, and lifestyle? This is where the use of essential oils comes in. Essential oils take the essence of plants. When they're used in particular ways, essential oil scents and their topical applications can benefit both your body and mind.

But with so many essential oils out in the market, plus myths about their uses, it can be overwhelming.

If you plan to start your own oils business, this guide will walk you through the top 12 essential things you need to know about essential oils. We’ll discuss what essential oils are, how they work, and, most importantly, how to use them safely.

1. Essential oils come from plants

Essential oils come from different parts of plants - flowers, leaves, roots, and bark. These oils take the plant’s scent, flavor, and beneficial compounds.

The most common methods of extracting oils are:

• Steam Distillation: This is where steam is used to extract essential oils from plant materials. As the steam passes through the plant, it pulls the oil out. It is then separated and collected.

• Cold Pressing: Cold pressing involves pressing or squeezing the plant material to release its oils. This method helps maintain the oil's natural fragrance and properties.

• Solvent Extraction: This method is less common, but it uses alcohol or another solvent to extract essential oils from delicate flowers that may not survive the heat of steam distillation.

The concentrated nature of essential oils means that even a few drops can deliver potent effects. This is part of why they’re so appealing for health-supporting practices.

2. Essential oils work in two common ways

Essential oils interact with the body in two primary ways: through smell and through the skin. Both methods have special benefits and effects. It’s part of what makes essential oils so versatile.

Let’s breakdown these two:

Through Smell (Aromatherapy)

When you inhale essential oils, their properties travel through your system until it reaches the limbic system in the brain. Your brain’s limbic system is responsible for your emotions, memory, and mood.

The direct connection between scent and emotion is why essential oils are used for aromatherapy.

Each of these methods have their time and place, but it depends on your personal goals. It’s important to know that the right essential oils can help you:

• Relax: Lavender essential oil and chamomile essential oil are known for having calming effects. They’re famous for reducing stress and anxiety.

• Boost Mood: Oils like lemon essential oil and orange essential oil can lift your spirits. It can also energize individuals.

• Enhance Focus: Peppermint essential oil and rosemary essential oil can enhance mental clarity and improve concentration.

Through Skin Absorption (Topical Use)

A popular way of using essential oils is to put them on your skin. When applied this way, they are absorbed into the bloodstream through the pores. Topical use allows oils to:

• Improve Skin Health: Tea tree essential oil and frankincense essential oil can help with acne, aging, and skin irritation.

• Support Muscle Recovery: Peppermint essential oil and eucalyptus essential oil are two examples of oils that are commonly used for soothing sore muscles or reducing inflammation.

• Improve Circulation: To improve blood flow and overall circulation, ginger essential oil and other similar oils are the key.

3. Essential oils carry health and wellness benefits

Essential oils are known for their wide range of health and wellness benefits. Let’s go over some of the key benefits of essential oils. We’ll also talk about the oils that are known for said benefits:

• Stress relief and relaxation. Studies have shown that inhaling calming scents can help you unwind after a long day or manage anxiety. Lavender, chamomile, and bergamot oils are known for their ability to soothe you, lessen stress, improve sleep quality, and even calm the nervous system.

• Mood enhancement. Essential oils like peppermint, orange, and lemon, are known for being uplifting. They help improve your mood, boost your mental state, and help relieve feelings of sadness or fatigue.

• Better sleep quality. Health and wellness experts have used essential oils for a long time. Lavender, sandalwood, and cedarwood essential oil are known for helping people with their insomnia or restless nights.

• Pain and inflammation relief. The right essential oils can reduce swelling and lessen pain and discomfort in your body. Ginger essential oil is popular for its warming properties, but also its ability to lessen pain and improve circulatory system functions.

• Support the digestive system. Some essential oils carry benefits for your digestive system. It can help with nausea, indigestion, and bloating.

• Skincare benefits. Essential oils have a long history of being used for African skincare. They are in lotions, serums, and creams that help repair and nourish the skin. For instance, tea tree oil is good for acne treatment. Rose essential oil is popular for keeping the skin hydrated and wrinkle-free.

4. Essential oils are not cure-alls

As beneficial as organic essential oils are, they are not cure-alls. They can support overall wellness and help ease certain symptoms, but they are not a replacement for medical treatment.

Oils like tea tree and lavender have anti-inflammatory and antiseptic properties, but they cannot replace antibiotics or other prescribed medications.

Think of essential oils as additional health and wellness support. They’re not stand-a-lone cures for health issues, but they can help support your journey towards full health and wellness.

In order to experience the essential oil benefits, it’s important to learn about what’s in each essential oil. Remember to read labels carefully and identify precautions. Follow the “How to Use” instructions very closely.

If you have specific health conditions or are taking medications, ask your doctor to check how essential oils can potentially interact with certain treatments.

Using these oils responsibly and knowing their limitations can help ensure a positive and safe experience.

5. Essential oils can expire

No matter how well you store them, essential oils can and will expire over time. Unlike artificial fragrances, pure essential oils are highly concentrated plant extracts. They break down naturally over time. Knowing how to identify expired oils and proper storage techniques can help essential oils’ shelf life.

So how do you tell if essential oil has expired?

The oil may develop a stale, musty, or “off” smell when it’s no longer fresh. Some oils, such as citrus oils, might darken or develop a cloudy appearance over time. If you notice an oil becoming thicker than usual or has a changed texture, it’s a sign that it has oxidized and lost its beneficial properties.

How long essential oils last depends on the type of oil and how it’s stored:

• Citrus Oils: These have a shorter shelf life, often lasting 1–2 years.
• Most Other Essential Oils: Oils like lavender, peppermint, and eucalyptus generally last 3–5 years.
• Resins and Woods (e.g., Sandalwood, Frankincense): These can sometimes last up to 6–10 years when stored properly.

6. Essential oils are natural and mostly safe

One of the biggest appeals of essential oils is their natural origin. They don’t have artificial additives or chemicals. When used correctly, essential oils can be a safe and effective way to enjoy the benefits of plants.

Essential oils are usually made through methods like steam distillation and cold pressing. These methods keep the oils as pure as possible, so they can keep their therapeutic benefits. And unlike the usual beauty and wellness products, pure essential oils only go through minimal processing. That means there is less risk of irritation or side effects caused by artificial chemicals.

7. The best essential oils can have healing properties

Research has shown that some oils carry therapeutic properties that may benefit certain conditions. They serve as complementary tools to help manage symptoms and improve well-being.

Scientific Findings About Essential Oil Benefits

Essential oils like lavender, chamomile, and bergamot have been studied for their ability to provide relief from stress and anxiety.

Research suggests that inhaling lavender oil can reduce anxiety levels. It promotes relaxation and even lowers blood pressure and heart rate in some cases. Bergamot and chamomile are similarly shown to positively affect mood and reduce stress when used in aromatherapy.

Lavender, chamomile, and sandalwood are also recommended for people struggling with insomnia. There are studies around these oils that show how beneficial they are to a person’s healthy sleep cycle.

The right essential oils can also help with headaches and tension-related pain. For instance, diluted eucalyptus essential oil helps ease sinus-related headache pain.

Some essential oils are also helpful for fighting bacteria and other mild skin irritations.

Areas Where Continued Research is Needed

Lots of studies show promising results, but more research is needed to fully understand the long-term effects and limitations of using essential oil.

Some studies on essential oils have small sample sizes or focus on short-term effects. And since essential oils are not regulated as medications, their quality can vary widely. This varied level of quality may affect their effectiveness.

As we’ve mentioned before too, essential oils are a complement to medical care - not the whole cure. Essential oils can support your well-being, but they shouldn’t replace treatments recommended by healthcare professionals - especially for serious or chronic conditions.

8. Most essential oils are good for diffusers

One of the most popular ways to enjoy essential oils is by diffusing them into the air. When used in a diffuser, essential oils release a fine mist, so you can inhale their beneficial compounds. This method of consuming essential oil is good for helping you relax, purify the air, and enhance your mood.

However, it’s important to avoid diffusing essential oils around children, pets, and pregnant women. These groups of people are known for being largely sensitive to strong scents.

The safest and most common essential oils used for diffusing are lavender, peppermint, eucalyptus, lemon, and frankincense.

Keep these practices in mind when diffusing essential oils into a room:

• Use the Right Amount: 3-5 drops of essential oil are enough for a standard-sized diffuser. Too much of it can cause headaches or irritation.

• Ventilate the Room: Make sure that fresh air can circulate through the room. Keep the area well-ventilated to prevent over-saturation of the essential oil mist.

• Diffuse in Intervals: Diffuse oils for short periods. 15-30 minutes with breaks in between should be good. Doing it this way prevents overexposure and maximizes the beneficial effects.

• Choose High-Quality Oils: Use 100% pure, therapeutic-grade essential oils for diffusion. You’ll want to avoid inhaling harmful additives or chemicals in essential oils.

9. Essential oils work well with carrier oils

Essential oils are highly concentrated extracts. Using them directly on the skin may cause irritation or sensitivity. To safely apply essential oils, they should be diluted with carrier oils.

This method makes the oils gentle enough for topical use while maintaining their beneficial properties. Much like essential oils, carrier oils are typically plant-based. Each one has unique benefits that complement essential oils. Some popular carrier oils you should know about are:

• Coconut Oil: Highly moisturizing and a popular choice for skin applications and massage blends.

• Jojoba Oil: The oil that closely resembles skin’s natural sebum. It is great for all skin types and beneficial for sensitive skin.

• Sweet Almond Oil: Lightweight, nourishing, and rich in Vitamins A and E.

• Olive Oil: The most readily available option. It works well for dilution but has a stronger scent compared to other carriers.

• Grapeseed Oil: This lightweight oil absorbs quickly and is great for oily or combination skin.

10. High-quality essential oils come with certifications

Quality matters when it comes to essential oils. You need to choose oils that are pure, organic, and free from artificial additives. A reputable supplier or seller will be transparent about their sourcing, extraction methods, and purity.

Here’s how to identify high-quality essential oils:

• Check for purity. The label should say 100% pure essential oil - no added fillers, synthetic fragrances, or diluents. Terms like “therapeutic-grade” and “organic” are a good sign.

• Check for botanical names. Reliable brands include the scientific (Latin) name of the plant on the bottle, such as Lavandula angustifolia for lavender. This level of detail shows that the brand is specific about sourcing and quality.

• Organic and non-GMO. Oils labeled organic and non-GMO are cultivated without synthetic chemicals. This entails a purer product. This is especially valuable for oils used in skin care, inhalation, or diffusers.

• Country of origin. Essential oil quality differs depending on the region where the plant is grown. Most reputable brands list the country of origin.

High-quality essential oils also go through meticulous testing to confirm their purity and potency. Look for proof of third-party testing, and certification labels such as USDA Organic, Non-GMO Project Verified, or ECOCERT.

These are signs that the oil has met specific purity and production standards. Certifications can also help confirm that an essential oil is produced without harmful pesticides or synthetic additives.

11. Using essential oils can come with risks

Always remember that natural doesn’t always mean risk-free. Lots of people assume that because essential oils are natural, they are automatically safe for everyone. But just like all natural substances, these oils can still cause allergic reactions, skin irritation, and other sensitivities.

Remember to use essential oils with a sense of respect and care, especially if you’re new to them.

Improper use of essential oils can lead to skin irritations and sensitivity and dangerous allergic reactions. Ingesting oils in large amounts can cause digestive discomfort, nausea, and even toxicity. Poorly diffused essential oils can also cause respiratory issues and it can trigger asthma or allergies.

Here are some tips for safely using essential oils for skin or overall health:

• Dilute oils with a carrier oil. A common dilution ratio is 1–2 drops of essential oil per teaspoon of carrier oil.
• Before applying an essential oil to a larger skin area, do a patch test on a small part of your skin (like the inside of your forearm) and wait 24 hours to check for any reaction.
• Limit diffusion time to about 30–60 minutes to avoid the harmful effects of overexposure.

When used correctly, essential oils can be powerful tools for wellness. But, by understanding their potential risks and taking precautions, you can enjoy them safely and effectively.
