Best Essential Oil Diffusers for Asthma

Suffering from asthma can be difficult, as there is no known cure. However, many have praised the healing and soothing effects of essential oils for asthma.

Have you ever enjoyed the aroma of a rose? If so, you have experienced what essential oils are like.

Essential oils come from plants and are highly concentrated versions of the plants’ natural oils. The oils take on the characteristics of the plants, both the smell and any of the plants’ characteristics.

When purchasing oils, you can opt for a single oil from a particular plant or oil blends, which combine oils to produce a certain effect. Essential oils increase energy, improve health and improve sleep.

Once you have decided to use essential oils, you might want to try an essential oil diffuser. These units disperse essential oils into the atmosphere so you can better experience their healing and therapeutic properties.

Essential oil diffusers range in type and price, so there are many available to choose from.

Suggested oils for those suffering from Asthma

Asthma causes inflammation of the airways, which lead to symptoms such as difficulty breathing, tightening of the chest and wheezing. Essential oils diffused into the air can ease these symptoms. The oils known to help those suffering from asthma include the following:

  • Lavender – Most popular and known for its relaxing properties. It helps fight inflammation and the accompanying breathing problems.
  • Eucalyptus – Breaks up phlegm and mucous, which improves breathing by clearing the airways.
  • Peppermint – Acts as a natural antihistamine and decongestant, keeping the airways open to enhance breathing.
  • Chamomile – Relieves muscle contractions that can restrict swollen airways, which helps improve breathing.
  • Tea tree – Helps break up mucous that blocks the airways, allowing easier breathing.
  • Clove – Helps reduce inflammation, aids in breathing and reduces muscle spasms.

As always, check with your doctor before using any new oils, as some of these may interfere with your asthma rather than alleviate the symptoms.
