Essential Oils: What You Need to Know Before You Start Using Them
Essential oils are becoming more and more popular for their calming fragrances and potential healing properties. If you’re using them to relax, ease pain, or simply to give your house a pleasant odor, there are some things you need to know about what they are, how they work, and how to use them correctly.

1. What Are Essential Oils?
Essential oils are highly concentrated plant extracts—preserving their fragrance, or “essence.” Oils are produced from various plant parts—leaves, flowers, bark, or roots. They are applied by people in aromatherapy or diluted for external use, but they don’t work for everyone. Every oil has distinctive properties and what it may do for your health.
2. Popular Essential Oils and Their Potential Benefits
Here’s a glimpse at some popular essential oils and what the science has to say about their potential:
- Lemon Eucalyptus: Sought for its anti-inflammatory, antioxidant, and immune-strengthening qualities. Certain studies indicate it may assist with certain infections or even viruses, although further human studies are necessary.
- Frankincense: With its earthy, rich scent, frankincense has been utilized in religious and self-care practices for centuries. Although some utilize it to aid in inflammation or stress relief, there is still developing scientific evidence.
- Lemongrass: With its antioxidants and antimicrobial activity, lemongrass oil has been traditionally utilized to alleviate pain, digestive problems, and fever. It can possibly be used to provide relief for joint pain and inflammation.
- Peppermint: This invigorating oil is a favorite in natural health communities. It’s commonly employed for headaches, stomach upset, or just to clear the air. But it’s strong—consult with a health care provider first if you have an illness.”.
- Rosemary and Chamomile: Early research indicates rosemary oil may relieve congestion and inflammation, particularly in asthma patients. Chamomile is also said to have calming, anti-inflammatory properties and can contribute to relaxation and minor respiratory ailments.
3. Using Essential Oils Safely
There are numerous ways essential oils can be consumed:
- Inhalation: With a diffuser, spray, steam inhaling, or a cotton ball drop.
- Topical Application: Always dilute in a carrier oil (such as coconut, jojoba, or almond oil) before topical application.
- Baths: A few diluted drops can add a relaxing scent to a warm bath.
Never apply the essential oils directly to skin undiluted—they are potent and will irritate.
4. Safety First: Know the Risks
Essential oils may be natural, but they’re also extremely concentrated and can lead to:
- Skin irritation or allergic reactions
- Eye or mucous membrane sensitivity
- Shortness of breath, particularly in individuals with asthma or respiratory problems
Always do a patch test prior to applying a new oil to your skin. If irritation occurs, discontinue use at once.
5. Essential Oils and Asthma: Use With Caution
Others. Turn to such oils as rosemary or eucalyptus for relief from asthma, but there is a good chance that inhaling the essential oils can trigger asthma attacks or allergic reactions. The Asthma and Allergy Foundation of America says there’s not much solid evidence that essential oils assist with asthma, and pungent scents can irritate symptoms. Always consult your physician before using essential oils if you have asthma or other breathing issues.
6. Selecting Quality Oils and Storing Them Well
Essential oils are not FDA-regulated, so quality is highly variable. To remain safe:
- Purchase from reputable companies that provide transparent sourcing and purity commitment.
- Keep the oils stored in an area that is cool and dark to maintain their quality.
- Keep lids tightly sealed to protect against contamination or spillage by accident.
7. Who Should Avoid Essential Oils?
Not everyone must use essential oils. Exercise special care if you are:
- Pregnant or nursing
- On medications that can interact with plant chemicals
- Dealing with chronic health issues
Always consult a healthcare professional before adding essential oils to your well-being regimen.
8. Never Consume Essential Oils
This is a large one: don’t ingest essential oils. Even in small quantities, they are toxic. Consuming eucalyptus oil, for instance, causes nausea, dizziness, or seizures. Essential oils must be used only for inhalation or thin topical application—never ingested without expert advice.
9. Keep Pets Safe
Most essential oils are toxic—or even deadly—to animals, particularly birds and cats. Even with small quantities in a diffuser, they can be problematic. Store oil away from your pets’ reach, and do not use it in areas where they eat, sleep, or linger.
10. Final Thoughts: Benefits of Boundaries
Essential oils can be a great addition to a self-care routine—but they’re not magic bullets. Use them with respect, keep up with danger reports, and talk to a health expert before incorporating them into your daily self-care routine regularly, particularly if you have health issues or take medications.
