Over the past few decades, the popularity of complementary and alternative medicine (CAM) has drastically increased, and essential oils are a part of that.
But what are essential oils exactly? For those new to this trend, these potent oils are extracted from plants to capture their scents, tastes, and other beneficial properties.
Whether you are looking for essential oils for hair growth or skin improvement, they offer a few health benefits. Not only that, but they are also widely used for aromatherapy.
How Do Essential Oils Work?
Essential oils are not intended for internal use unless you’re working with a licensed professional.
Essential oils are most commonly used by inhaling them, or applying them topically.
Any plant chemicals are absorbed when applied to your skin. It’s thought that specific application methods can improve absorption, such as heat application or different areas of the body. Nevertheless, research in this field is a bit lacking.
Oils can also be inhaled from the bottles, or with a diffuser. Inhalation affects the limbic system, which can affect the limbic system and by extension, things like emotions, memory, and stress, among other things.
Health Benefits of Essential Oils
Following are some of the evidence-based health benefits that essential oils offer:
Essential Oils for Anxiety and Stress
Using essential oils for anxiety and stress has proven to be effective. 43% of individuals with stress and anxiety are reported to use alternative treatment to help alleviate their symptoms.
Initial studies have been very optimistic for aromatherapy. Many have shown that alongside conventional therapy to treat anxiety and stress, the scent of specific essential oils can function.
However, it is difficult to perform blind experiments and rule out prejudices due to the compounds’ scents. Therefore, some studies have not been definitive on the stress-and anxiety-relieving impact of essential oils.
Essential Oils for Sleep and Insomnia
If you are looking for essential oils for sleep, it has been shown that smelling lavender oil enhances the quality of sleep for women after childbirth and heart disease patients.
Essential Oils for Headaches and Migraines
Two small experiments in the ’90s showed that dabbing a combination of peppermint oil and ethanol on the foreheads and temples of participants alleviated headache pain.
After applying lavender oil and peppermint to the scalp, recent studies have also observed decreased headache pain.
What’s more, it was suggested that the application to the temples of a mixture of chamomile and sesame oil may treat headaches and migraines. Using essential oils for headaches is a common treatment for a Persian headache.
However, further high-quality studies are required.
Essential Oils for Inflammation
It has been proposed that essential oils can assist in treating inflammatory conditions. Some studies of test tubes suggest that they have anti-inflammatory effects.
One mouse study showed that the ingestion of a mixture of essential oils from thyme and oregano helped cause colitis remission. Similar findings were found from two rat studies on caraway and rosemary oils.
The effects of these oils on inflammatory disorders have been investigated in very few human studies. Their efficacy and safety are still uncertain.
Antimicrobial and Antibiotic
In the quest for other compounds that can combat bacterial infections, antibiotic-resistant bacteria’s growth has renewed interest.
However, while these test tube analysis outcomes are fascinating, they don’t necessarily reflect the effects inside your body of these oils. They don’t demonstrate that a specific essential oil can cure human bacterial infections.

How to Choose the Right Essential Oils?
Many businesses say that their oils are “pure” or “medical grade.” These words are not widely defined, however, and thus carry little weight.
The consistency and composition of essential oils can differ significantly, considering that they are products of an unregulated industry.
To select only high-quality oils, keep the following tips in mind:
Purity: Find an oil that contains aromatic plant compounds only, without synthetic oils or additives. Typically, pure oils list the plant’s botanical name (such as Lavandula officinalis) rather than words like “lavender essential oil.”
Reputation: To purchase a brand with a reputation for making goods of high quality.
Quality: Real essential oils are the ones that have been least modified by the method of extraction. Choose an essential oil that has been extracted by distillation or mechanical cold pressing that is chemical-free.
Safety and Side Effects
Just because there’s something normal doesn’t mean that it’s secure.
Many bioactive compounds that can harm your health are found in plants and herbal products, and essential oils are no different.
However, when inhaled or mixed with a base oil for use on your skin, most essential oils are considered healthy. Be sure to remember those who may be inhaling the scent in your setting, including pregnant women, kids, and pets.
Nevertheless, they may cause some side effects, including:
- Asthma attacks
- Allergic reactions
In general, you want to use essential oils in moderation. Literal tons of plant material go into a single bottle, so while these oils are beneficial, they’re incredibly potent and should be treated with respect!
And if you ever have any questions about their uses, it’s always best to consult your doctor or a licensed, reputable professional who’s knowledgeable about essential oils.
Since there are limited studies available, it’s hard to know what information you can trust. It’s always best to be cautious and avoid potential issues with using oils.
