Where does the tea tree grow?

The tea tree grows mainly in Australia.


– The tea tree is a plant from the same family (myrtaceae) as the eucalyptus, and therefore originally from Australia. There, tea tree is widely used and can be found in all pharmacies.

– Its essential oils (rich in terpenes) have shown great effectiveness against mycoses, proven by several clinical studies.

– Tea tree is also effective against acne, similar to that of benzoyl peroxide (a molecule widely used in acne) but with fewer side effects, as it is known that benzoyl peroxide has a tendency to discolor fabrics ( clothes, towels,…) and can sometimes cause irritation. Tea tree essential oil can therefore be a great treatment in case of mild to moderate acne. If you adopt a tea tree cream, give preference to those based on tea tree essential oil whose concentration varies between 5 and 15%. Do not use tea tree in case of rosacea as it can aggravate the symptoms.
