What are Essential Oils?

Essential oils — plant extracts — are created by steaming or pressing different parts of a plant, such as leaves, flowers, fruits, etc. to extract the compounds that provide the aroma. A single bottle of essential oil can be made from several pounds of a plant.

Besides producing fragrance, these oils have many other functions about which we’ll talk in a minute.

What Is Aromatherapy?

Aromatherapy is when you use essential oils for therapeutic purposes. It has been practiced for millennia. When a person inhales, the scent molecules of essential oils move directly from the olfactory nerves to the brain, affecting the amygdala — the brain’s emotional center. During aromatherapy, you use essential oils to inhale them via your nose or put them on your skin to take a bath or get a massage.

Smells can elicit emotions and memories since the system is involved in memory formation. People believe that using essential oils on your skin and massaging them in relaxes your muscles. Each essential oil can have different effects but further research and studies are needed for more facts.

Disadvantages of Essential Oils

Now it’s time to dive into the disadvantages of essential oils and what kind of side effects they may have on health:

Allergic Reactions

In some cases, people might have irritation or allergic reactions to essential oils. Some of them can irritate your eyes, skin, and the mucus membranes of your nose. Some oils are considered more problematic than others and are jasmine, chamomile, ylang-ylang, lemongrass, bergamot, etc. Because essential oils are so strong, diluting them with a carrier oil is the best method to avoid a negative reaction while applying them to your skin. Don’t forget about patch testing before applying the essential oil to ensure that you don’t have any allergic reactions.

Ensure to follow these crucial steps:

  • Use unscented soap and wash your forearm.
  • Dry gently.
  • In a small part of your forearm, apply a few drops of diluted essential oil.
  • Wait for at least 24 hours.
  • Wipe it.

If you see some irritation, such as red and itchy skin, then definitely you have allergic reactions and must not use the oil. If an uncomfortable feeling of itching appears before the 24-hour period passes, you need to wash your forearm as fast as possible, using water and soap.

Asthma Attacks

The safest method to utilize essential oils is to inhale them through a smelling accessory or diffuser. Scents are known to elicit strong emotions and memories in people. Some oils have relaxing effects, and many people find specific scents to be soothing.

There are still certain hazards associated with using essential oils in this manner. While some promote essential oils as a strategy to relieve asthma symptoms, these compounds can potentially cause asthma attacks in some people.


Other negative effects of aromatherapy treatments include headaches, nausea, and light-headedness. However, these symptoms are not as harmful and you can get rid of them once you discontinue using essential oils or wash them off.

As a general rule, using anything in excess can be harmful to your health. As a result, you should use each thing in moderation to avoid harming your health. And always consult with your doctor before using essential oils.
