Acne, dandruff and fungal infections – what can tea tree oil really do?

Benefits are promising, but misuse can cause irritation and allergic reactions

Tea tree oil (Melaleuca alternifolia) is one of the most studied essential oils. It is derived from the distillation of tea tree leaves, native to Australia, and contains compounds that have shown antimicrobial and anti-inflammatory activity in laboratory studies.

However, this does not mean that tea tree oil is a “natural remedy” for every skin problem. According to the National Center for Complementary and Integrative Health (NCCIH), there is some evidence that topical use can help with acne and athlete’s foot, but for many other uses the evidence is still insufficient.

One of the most studied uses of tea tree oil is the treatment of mild to moderate acne.

Some studies have shown that preparations with 5 percent tea tree oil can reduce the number of pimples and acne severity. A randomized clinical trial in 60 people found improvement after using 5 percent tea tree oil gel.

However, a newer review of studies says stronger evidence is needed to determine its effectiveness for sure.

Some data shows that tea tree oil may help relieve symptoms of fungal foot infections, especially in cases of mild.

However, the NCCIH points out that it may not be as effective as standard treatments and the evidence is still limited, Telegraph reports.

Tea tree oil has also been studied for onychomycosis, but the results are not as convincing. According to the NCCIH, only a few studies have been conducted and the quality of the evidence is not sufficient to draw a firm conclusion.

Therefore, in the case of an advanced nail infection, it should not replace treatment recommended by a dermatologist.

Some hair care products contain tea tree oil and have been studied for dandruff and itchy scalp. However, the clinical evidence for different uses of this oil is not equally strong.

For this reason, it is better to use products specially formulated for the scalp rather than pure essential oil.

One of the most important rules is: tea tree essential oil should not be ingested.

When used on the skin, it is safer to choose ready-made products with suitable concentration, instead of applying the pure oil directly. on skin.

Undiluted oil may cause redness, burning, itching, dryness or contact dermatitis. The NCCIH also warns that oxidized oil, meaning one that has been exposed for a while to air, light, or heat, may cause more allergic reactions.

Before using a new product, test a small area of skin and observe if any reaction occurs.

Who should be especially careful?

People with very sensitive skin, eczema, or a history of allergic reactions to essential oils should be careful.

Also, tea tree oil should not be taken by mouth. Ingestion can cause serious symptoms, especially in children.

It should not be applied to deep wounds or serious infections without a doctor’s advice.

Not every “natural” use is proven

Tea tree oil is being studied for many other uses, including various skin problems and infections. But laboratory results are not the same as clinical trials in humans.

Therefore, although the oil has interesting antimicrobial properties, it should not be seen as a substitute for proven treatments.

If used properly and in appropriate preparations, it can be a useful adjunct for some mild skin problems, but “natural” does not automatically mean safe or effective for every condition.
