I have been providing you with resources and information on new essential oils resources. This is to empower you with education for their safe use and to take advantage of these new aromatic tools for living a healthy, non-toxic lifestyle.

Last week, I started reviewing Kunzea essential oil. It is truly a unique essential oil. It is a single oil with a chemical makeup that makes it behave more like a blend. You can catch summary of its awe-inspiring properties, uses, chemistry, and my own personal experience by watching this video.

After noting its profound emotional effect on me and the accolades of Kunzea ambigua form my essential oil mentors, it was my desire to continue to learn more and share it with you. Below is a summary of what I found.*

A Review of Studies on the Benefits of Kunzea Essential Oil


1. Supporting an Annoyance Free Outdoor Event

In a test with human volunteers, Kunzea ambigua showed minor repellency against some annoying critters outdoors. Several other articles refer to Kunzea’s potential for this as well.

Although in this study, Kunzea was less effective than DEET, there is the benefit of it being a  less toxic choice. (You  may want to read this on why I’m wary of DEET.)

Another option to save your hands from swatting critters all day  is this Insect Repellent.

I think I may add a little drop of Kunzea oil to my bug-away goop for when I head out to explore and find the great outdoors especially populated creepy-crawlies!



2. Keeping Kids Hair Critter-Free

In a 2016 in vitro study, the authors state:

Head lice (Pediculus humanus capitis) infestations are a public health concern. The insecticidal properties of the Australian native plant Kunzea ambigua (commonly known as tick bush) have been documented. In this study, we tested activity of kunzea oil (KO) against head lice through in vitro bioassays. Head lice were exposed to filter paper treated with either KO, as either a 5 or 100% oil, or commercial formulations containing either permethrin or tea tree oil (TTO) for 120 min. Head lice exposure to KO, both as a 5 and 100% solution oil, resulted in 100% mortality within 120 min with a mean survival times of 17·1 and 34·8 min, respectively. There was no significant difference between the mean mortality of head lice exposed to 5% KO (17·1 ± 1·0; 95% CI: 115·2–19·0) and 5% TTO (21·2 ± 1·9; 95% CI: 17·4–25·1). This study revealed, for the first time, that KO holds great potential as an effective alternative to current active ingredients contained within commercial pediculicide formulations. 

Although petri dish studies cannot be generalized to humans, in this situation this study is helpful. This is because it is based on a topical application of the essential oil to a critter. It is not extrapolating the action of an isolated compound from an essential oil that has to be further biotransformed in the organs of elimination of the human or mammal.



3. Skin Care in Humans, Horses, and More Proof of Inhibiting of the Unwanted Buggies

In this thesis on Kunzea, the author reviews:

The differences between species of Kunzea

The potential for its ability to blot out unwanted microbes and annoyances

Kunzea’s action on a skin condition in horses and toenail fungus in humans

The review states:

For thousands of years natural products have had a prominent role in treating ailments. Among the plant-derived products used as medicinal agents, essential oils have been widely appreciated for their use as antimicrobial agents. Myrtaceous essential oils have also attracted industrial interest primarily due to their antimicrobial properties. Tea tree oil is the prominent contender. Kunzea oil is a myrtaceous essential oil obtained from the shrub Kunzea ambigua (Smith) Druce 1917. K. ambigua, genus Kunzea, family Myrtaceae, is endemic to northeast Tasmania as well as the Furneaux Islands and eastern coastal regions of Victoria and southern New South Wales. Kunzea oil has been listed as a therapeutic substance by the Therapeutic Goods Administration in Australia for topical application for the treatment of various dermatological ailments (AUSTL 72143; 1996). Kunzea oil is currently used in aromatherapy, as a topical antiseptic and for the treatment of various bacterial-fungal skin infections, eczema and psoriasis in humans and pastern dermatitis in horses. The initial objective of the study was to examine the chemical composition, antimicrobial activity and the insect repellency potential of kunzea oil. The second phase of the study investigated the potential usefulness of kunzea oil for the treatment of onychomycosis and efficacy of formulations containing kunzea oil for the treatment of pastern dermatitis in horses, in randomised controlled trials.

Investigation on the chemical composition of kunzea oils demonstrated differences
between oils from different plants (Kunzea spp.) analysed in this study. The results from the repellency trial indicated that K. ambigua essential oil offers protection from biting mosquitoes similar to that afforded by citronella oil. Kunzea oil-based formulations may be suitable for use in areas of low mosquito activity
by people who wish to avoid the use of synthetic repellents. Kunzea oil appears to possess potentially useful in vitro antimicrobial activity with some fractions having higher activity. However, more work is required to further establish the optimum antimicrobial potential of kunzea oil. Two of the randomised clinical trials demonstrated the potential clinical usefulness of kunzea oil based topical formulations to treat pastern dermatitis in horses and pedal fungal infections in humans. Results of the pilot in vivo investigations open several avenues for further work in the form of in vitro bioassays and randomised, controlled trials for the development of topical formulations as an addition to the current battery of topical modalities for the management of cutaneous infections in humans and animals.

4. The Power of a Patent

In a patent application, “Essential Oil of Kunzea Ambigua and Methods of Use,” the abstract states:

A method for treating disease includes the steps of obtaining the essential oil from the Kunzea ambigua plant and administering the essential oil obtained to a human to take internally. The essential oil of the Kunzea ambigua plant has been discovered to act positively against parasitic infestation of humans and animals, and also has been found to have high kill rates against various viral and bacterial infections.

You can read all its descriptions and claims here.



Kunzea essential oil is an amazing addition to anyone’s essential oils toolkit. It has many varying properties due to its distinct makeup. I believe that we are only beginning to explore its power. This weekend, my mom had the same response that I did with this oil.
