The Best Essential Oils for Mucus Cough

best essential oils for mucus cough

Here are some of the best essential oils:

1. Lavender Essential Oil

Lavender oil has amazing anti-microbial and anti-fungal properties which can help to clear mucus in the airways.

It also contains an active chemical compound called linalool, which helps with oxidative stress, inflammation, and cellular homeostasis.

This chemical component makes it very effective at boosting the immune system and the overall health of your respiratory system.

Some studies show that there are significant therapeutic effects of Lavender essential oil on airway inflammation and mucus-producing cell hyperplasia.

2. Peppermint Essential Oil

Peppermint essential oil has natural anti-fungal, anti-bacterial, and anti-viral properties. While it’s not a potent decongestant like Eucalyptus or Lavender, it does provide some relief as a decongestant.

It contains menthol, which can provide a cooling sensation and help soothe irritated airways.

This study shows that people who inhaled peppermint essential oil did not report any improvement but overall felt better.

3. Geranium Essential Oil

It is a volatile essential oil with a camphor-like odor. It is traditionally used to treat colds, sore throats, and bronchitis.

This study shows that inhaling Geranium essential oil can improve chest tightness, reduce mucus production, and has anti-inflammatory benefits in asthmatics. 

Researchers also found that there’s a connection between the geranium extract and reduced cough symptoms.

4. Thyme Essential Oil

Thyme contains a monoterpene chemical called thujone, which is a potent anti-microbial and anti-fungal.

It helps relieve respiratory issues like cough, bronchitis, and congestion due to its amazing decongestant properties.

In this study, it has been found that thyme essential oil can be used as an antimicrobial agent for a couple of respiratory issues including mucus cough.

5. Eucalyptus Essential Oil

Eucalyptus essential oil is used to ease cough and clear mucus in the airways by stimulating the respiratory system and reducing swelling in the throat.

It has anti-microbial as well as decongestant properties, which help to get rid of the congestion in your nose and throat.

A recent study on children shows that Eucalyptus essential oil can be used as a vapor rub to ease respiratory congestion and help children sleep better.

6. Tea Tree Essential Oil

Tea tree oil is known for its antibacterial and antiviral properties. It can help fight infections that may contribute to mucus production.

According to a study published in 2015, it can be used for the treatment of respiratory infections e.g. cold, influenza, and bronchitis.
