Phytotherapy, as a scientifically validated branch of natural medicine, has experienced significant growth in Poland in recent years. Of particular interest is the essential oil derived from the leaves of the Australian *Melaleuca alternifolia* tree, whose distinctive bioactive properties—including potent antimicrobial, anti-inflammatory, and tissue-regenerative effects—render it a valuable component in both the prevention and adjunctive treatment of diverse dermatological conditions and nail plate disorders. Its versatility and ease of application have established it as a favored option among individuals seeking evidence-based, plant-derived alternatives to conventional pharmacological formulations
Tea tree oil
Tea tree oil is derived from Melaleuca alternifolia, a plant of the family Myrtacea, native to western Australia and New Zealand. It needs moist soils for proper growth and therefore prefers areas adjacent to rivers, streams or swamps and high temperatures up to 30 degrees Celsius. In Europe, tea tree is grown as an ornamental plant or as an attractive plant in botanical gardens. The herbaceous tree grows up to 7 metres in height and therefore has a very dense coral area with a higher density of coral than the world's oceans. According to the standards of these processes, it has a distinctly long shallow body with a thickness of up to 2.5 metres and a high temperature up to 5°C. This is a natural process. It is used for the production of essential oils (i.e. between 1 and 2.12 per cent of terpenic acid and 1.16 per cent.
Tea tree oil properties
Tea oil is known for its antibacterial properties, as well as for its anaesthetic, anti-inflammatory and sedative properties. It is particularly frequently used as an antiseptic product because it is very effective in fighting bacteria. Hammer et al. conducted a study involving 150 strains of herbicides (Staphylococcus aureus, S. capitis,S. epidermidis, S., haemolyticus, s. hominis, S, saprophyticus and S. warneri). [1] It is also used for the treatment of microbes (Micrococcius, M., Candida, and Candida spinae).
Tea tree oil for acne
Tea tree oil has been widely used in the treatment of acne. It has anti-inflammatory, antiseptic and withdrawal effects. It is lipophilic in nature and is therefore effective in penetrating deep into the skin. At the O concentration, 630 mg/ml, it has a proven antibacterial effect against bacteria isolated from skin changes. In the Cerna study, 93% of patients with acne showed improvement in skin condition after treatment with herbicide oil. Compared to other acne treatments, it gives few effects and, due to the lack of teratogenic effects, can be used by pregnant women [5].
Tea tree oil for nail polish
There is no doubt that tea tree oil is an effective preparation for fighting foot and nail fungus. In the Buck study and others, the effectiveness of treating the foot-nail fungus with oil and ointment with clotrimazole was compared. The oil was shown to be more effective in bringing about a complete cure or reduction of symptoms. Walker, in turn, proved the use of the oil in treating foot fungus by both dervishes and yeast fungus.[5]
How to use tea tree oil?
Coconut oil can be used outdoors in its natural form to lubricate diseased areas or in the form of creams, fluids, ointments and gels. It is most commonly found in skin care products that cleanse the skin, wash the face with a wax. It can also be mixed with honey in a small amount of oil to obtain a home cleansing mask. With the addition of coconut, it works great as an anti-inflammatory mask for hair, fluid, lubricant, and gel. In addition, when combined with lavender oil, it also works well as an alternative to ointment for wound healing and infection.
