Cajeput Essential Oil Benefits

As part of the same family as the popular tea tree oil, cajeput essential oil also hosts a range of benefits for your body. If you’re looking for relief from minor coughs, help with skincare, or just a way to relieve joint pain, cajeput may be a good choice for you.

1. Respiratory support

Respiratory issues plague us at all times of the year. You may suffer from congestion during allergy season or even experience coughing from irritation due to bacteria. Many essential oils have constituents that help alleviate the body’s response to these irritants, including phlegm production, coughing, and bronchial tissue inflammation. Cajeput essential oil was studied in 1991 using the lung tissue of rats. It was found that the body’s allergic reaction, namely histamine production was reduced. (1) A further 2001 lab study found that cajeput was one of a series of essential oils that was effective against bacteria that could be responsible for bacterial flu and pneumonia. (2)

2. Skin Care

As the largest organ of our body, our skin is also the first defense we have against germs and other pathogens that can cause serious illnesses. We are at risk of infections every time our skin is cut or broken, whether by accident or from skin diseases. Many times, these infections can be enough to impact of self-image as well. In a 2012 lab study, cajeput was one of a set of essential oils studied for its effect on various types of microbes that are found on the skin. These microbes can cause infections or worsen skin conditions like acne. The study found that cajeput had a positive impact on the most common of microbes and may be effective in treating certain skin infections. (3)

3. Muscular and joint comfort

Muscle and joint discomfort are part of being human, but many times it can interfere with our everyday lives. Chronic pain caused by medical conditions like autoimmune disorders can leave you in pain for days, and many over the counter remedies are not recommended for repeated use and have a window in which you can’t take any more. A study in 2000 looked at the effects of 1,8 cineole on rats with induced paw edema. The results showed that inflammation was reduced as well as indicators of pain and anxiety. Fluid retention decreased in the affected limb, and there were fewer indicators of the nervous system’s response to pain. Cajeput’s most abundant constituent is 1,8 cineole, making it a possible choice for treating the pain and inflammation associated with joint and muscle pain. (4)

4. Bug Repellent

Though we may consider stinging insects like mosquitoes to be pests, many countries around the world are afflicted with serious diseases passed by these insects. This includes diseases such as dengue fever, malaria, and the zika virus. Essential oils are a more natural alternative that may be available when commercial repellents and insecticides are scarce. In 2006, cajeput was one of several oils tested for effectiveness in repelling mosquitoes. Researchers applied the oils to human volunteers and observed that cajeput was an effective repellent for common insects that are known to transmit blood-borne illnesses. (5)

Cajeput Essential Oil Uses

The uses for cajeput essential oil are as remarkable as other oils made from Australia’s plants. It can be used with a number of complementary oils that add to its already useful traits. With a camphor-like scent reminiscent of tea tree, cajeput may have plenty of uses in your home.

Aromatic Uses

  • During allergy season, diffuse 2 drops each cajeput, lemon, and thyme throughout your house. This may help kill common microbes that cause respiratory irritation.
  • Add 5 drops each to dried potpourri: lemon, tea tree, and cajeput. This will make a centerpiece that will help alleviate anxiety and improve mood.
  • Diffuse 5-7 drops in distilled water to help improve focus and mood.

Topical Uses

  • In a 3-ounce roller bottle, add 10 drops each of cajeput and peppermint oil and fill with a carrier oil of choice. Apply to insect bites to help with inflammation and itching.
  • Combine 2 drops each of cajeput, peppermint, and frankincense with 1 tablespoon of carrier oil and ½ cup Epsom salts. Stir well and add to a warm bath.
  • In a 2-ounce bottle, add 10 drops cajeput and 3 drops each peppermint, frankincense, and copaiba and top with carrier oil of choice. Apply to aching joints as needed.

My Favorite Uses For Cajeput Essential Oil

As the years creep up on me, I find myself suffering from any number of minor ailments. This is most usually in the form of aching muscles as I try to keep myself in some kind of shape to keep up with business, family, and life in general.

My hands, in particular, seem to bear the brunt of everything I do. I pull weeds in the garden, I hold onto heavy weights for strength training, and I’m on the computer for a large portion of my day. My fingers get slightly swollen from resting on the desk to type.

I’d always turned to over the counter medications to help with those aches, but they never seemed to last for long, and then I had to wait to be able to use them again. Essential oils were the answer to being pain-free between medication administration.

I use a roller bottle with cajeput, peppermint, and eucalyptus and roll it across any aches that come with age or the work I put into my health and job. I have one at my computer and one next to my workout equipment. It’s an indispensable part of my routine.

I particularly like being able to detect the aroma as it comes off my hands to enjoy a good mood along with a pain-free day.
