Tea tree is the name of a plant native to Australia, scientifically known as Melaleuca alternifolia.1 The oil extracted from the leaves of the tea tree is tea tree oil, a widely used ingredient in a variety of household and cosmetic products, like shampoos, massage oils, laundry detergents, and skin and nail creams for its potential antiseptic benefits. Tea tree oil is pale yellow in colour. It has a strong odour and may provide a cooling sensation on the skin.2 It has been widely used in Australia as a topical medicine for almost 80 years.3 Common names of tea tree include tea tree oil, Australian tea tree oil, melaleuca oil and tea tree essential oil.4

Chemical Constituents of Tea Tree

The main component present in tea tree oil is terpinen-4-ol. Tea tree oil contains more than 100 compounds.

These are alpha pinene, sabinene, alpha terpinene, D-limonene, p-Cymene, 1,8-cineol, gamma terpinene, terpinolene, terpinen-4-ol, alpha terpineol, aromadendrene, ledene, delta cadinene, globulol and viridiflorol.2

Did you know tea tree oil-based gel may aid in inflammatory gum disease called persistent gingivitis? Studies have shown that people using tea tree oil gel may have less bleeding and irritation.

Potential Uses of Tea Tree

Tea tree may have potential uses for various health conditions; however, more human studies are needed to support its true scope in humans.

Potential uses of tea tree for vaginal candidiasis  

The overgrowth of Candida albicans in the vagina is called vaginal candidiasis or thrush; it is a fungal infection. Tea tree oil may have the potential to be developed as an effective agent for managing vaginal candidiasis. The benefits of tea tree oil in vaginal candidiasis have been observed in lab studies. However, these studies are done in laboratories and not humans; therefore, extensive clinical trials are required to check its efficacy in human beings.3

Potential uses of tea tree for acne

Tea tree oil may have antibacterial and anti-inflammatory properties that might be useful in managing acne. Many topical preparations containing tea tree oil have been used to stop the bacteria involved in acne. The use of tea tree oil might significantly reduce acne lesions by decreasing open and closed comedones (blackheads and whiteheads). The antiacne benefit of tea tree oil has been observed in many clinical trials, which demonstrates that topical application of tea tree oil (5%) might be effective in managing mild to moderate acne.6 However, every person has a different response to different herbs. Therefore, it is better to consult a doctor before you use tea tree oil for your acne problems.

Potential uses of tea tree for fungal infections

Potential uses of tea tree for seborrheic dermatitis

Seborrheic dermatitis is a superficial fungal infection occurring in areas rich in sebaceous glands. Tea tree oil may have antifungal activity against Malassezia furfur, which indicates that it might be beneficial in the management of seborrheic dermatitis.6 However, you should never use tea tree oil to self-medicate yourself. It is better to consult a dermatologist for your dermatitis-related problems. They will be the best person to guide you with your condition.

Potential uses of tea tree for dandruff

Shampoo containing 5% tea tree oil was found to be effective in dandruff in a clinical study (human trial). Therefore, tea tree oil might be helpful in the management of dandruff.6 However, this study is insufficient; therefore, further studies are required to suggest the benefits of tea tree in fighting dandruff problems.

Potential uses of tea tree for wound healing

Tea tree oil was found to be beneficial in providing a cooling sensation to burn wounds and increasing the rate of wound healing.6 However, this information is insufficient and requires large-scale human studies to suggest the potential uses of tea tree oil for wound healing in humans.

Potential uses of tea tree for viral infections

Tea tree oil may have potential antiviral activity against herpes simplex virus 1 and herpes simplex virus 2. Tree tea oil may have shown effectiveness in recurrent herpes labialis infection (skin rash on lips caused due to herpes virus) in a clinical trial. Tea tree oil may have also shown benefits in dealing with hand warts caused due to human papillomavirus.6 However, if you have viral infections like the herpes simplex virus, it is best to seek medical help and get a proper diagnosis and treatment for your condition.

Potential uses of tea tree for head lice

Tea tree oil is found in many preparations that are used as an alternative solution for head lice infestation. Tea tree oil, along with lavender oil, has shown effectiveness in dealing with live head lice in subjects in a clinical study. The results indicate that tea tree oil may be beneficial as an alternative method for head lice.6 However, use these alternatives only under the guidance of your doctors.

Potential uses of tea tree for demodicisosis

Demodicisosis is an eyelid infection caused due to Demodex (a type of mite). Eyelid scrub using tea tree oil effectively eradicated eyelid demodex and helped with demodicisosis in a clinical study. Therefore,  it may indicate that tea tree oil and shampoo might be beneficial in eradicating eyelid Demodex.6 However, take medical help before using the tea tree for your infections and only use it if prescribed.

Though studies show the benefits of tea tree in different health conditions, these studies are insufficient and require further studies to establish the true scope of benefits of tea tree on human health. In addition, every person may respond differently to this herb. Therefore, it is essential to consult a doctor before using tea tree oil for any medical condition.
