Properties of Tea Tree essential oil

Tea Tree essential oil is highly concentrated in monoterpene carbides and alcohols. These different molecules give it the following main properties:

  • broad spectrum antibacterial ++++ (terpinen-4-ol):

    tea Tree essential oil is bactericidal through its ability to penetrate, permeabilize and liquefy the membrane of bacteria, causing the internal components of the bacteria to leak. Additionally, Tea Tree inhibits the growth of a wide range of bacteria. Studies have demonstrated its effectiveness on Escherichia coli and Staphylococcus aureus (often responsible for cystitis) and also Cutibacterium acnes (the cause of acne).

  • broad spectrum antifungal ++++ (terpinene-4-ol, γ-terpinene, α-terpinene):

    the aromatic molecules contained in the Tea Tree have the ability to insert themselves into the membrane of certain mushrooms. The membrane being involved in certain vital parameters, the growth and development of the fungus, this therefore causes their elimination and allows Tea Tree to be effective in cases of mycoses such as candidiasis or dermatophytoses for example. The Tea Tree has been the subject of several conclusive studies on mushrooms of the genus Candida (albicans, glabrata) And Malassezia (globosa, furfur) among others.

  • antiviral +++ (terpinene-4-ol, γ-terpinene, α-terpinene):

    the main components of Tea Tree have a virucidal action and can prevent contact between viruses and the body's host cells. Studies of enveloped viruses such as Herpes simplex viruses type 1 and 2 (HSV-1 and HSV-2) have found that Tea Tree molecules insert into and destroy the virus shell, causing leaking internal components such as its genetic information.

  • antiprotozoal, antiparasitic +++ (terpinene-4-ol, γ-terpinene, α-terpinene):

    tea Tree essential oil penetrates directly into the external cells of the parasite, which results in altering its cell membranes and its intracellular constituents. Tea Tree also limits the development of larvae of intestinal parasites and limits the hatching of eggs of certain parasites.

  • immunomodulating ++ (terpinen-4-ol):

    studies have shown that Tea Tree has the ability to modify the production of certain inflammatory mediators (TNF-α, IL-1β, IL-8, IL-10, prostaglandins E2, immunoglobins A and M, etc.) which are involved in the body's immune response. In addition, it would be capable of increasing the expression of the CD11b receptor, responsible for phagocytosis, that is to say the elimination of pathogenic elements by white blood cells.

  • radioprotector ++ (terpinene-4-ol, γ-terpinene, α-terpinene):

    the anti-inflammatory and slightly antioxidant properties of Tea Tree make it an interesting essential oil for preventing radiodermatitis, that is to say skin burns caused by radiotherapy.

But also these secondary properties:

  • anti-oxidant

To check before using Tea Tree essential oil

Favor organic as soon as possible

Tea Tree essential oil, whether from South Africa or Australia, may contain significant levels of pesticides if it is not ORGANIC. Contrary to some rumors, distillation does not eliminate these pesticides. Essential oils have excellent bioavailability (whether orally or cutaneously), the use of non-ORGANIC essential oils presents a significant risk. In addition, growing an ORGANIC Tea Tree will be much more environmentally friendly, through the ban on pesticides and synthetic fertilizers. Finally, certification by an ORGANIC label guarantees a minimum of traceability and prevention of manufacturer fraud. For all these reasons, we recommend that you preferably purchase a organic Tea Tree essential oil, especially since the price difference is often minimal.

Check chemotype

The concept of chemotype in aromatherapy is essential to guarantee the quality of an essential oil. An essential oil can be called chemotyped if its label specifically mentions: its precise botanical definition (including genus, species and subspecies or variety), the main molecules that it contains and the precise geographical origin of the plant from which the essential oil comes. You will therefore need to check that the chemotype is correctly indicated, but also that it is the correct chemotype. For the Tea Tree, it's quite simple: 

  • Precise Latin name: Melaleuca alternifolia (Maiden & Betche) Cheel
  • Main molecules: terpinèn-4-ol, γ-terpinene, eucalyptol (1,8-cineole), α-terpinene and paracymene
  • Origin: South Africa or Australia

For reasons of effectiveness and safety, the choice of a good chemotype is often crucial in aromatherapy, as the biochemical compositions of oils vary greatly from one chemotype to another. Tea Tree, however, presents a fairly low risk from this point of view, the majority of products available in France respecting this chemotype. 

Request access to analytics

Understanding all the analyzes carried out by a manufacturer to ensure the good quality of an essential oil is not within everyone's reach. However, you can ensure that these analyzes exist, for each batch, and that they are public. This is the best guarantee of quality that a brand can give to its customers. You will be able to find, at least, for each essential oil: its chromatographic analysis, its organoleptic analysis and some physical analyzes (density, rotational power, refractive index). Regarding Tea Tree, the results you can expect are listed above.
