Aim of this paper is to show antimicrobial, antifungal, antioxidant and acaricidal properties of tea tree (Melaleuca alternifolia). Tea tree exhibits wide spectrum of antimicrobial activity. Its mode of action against the Gram-negative bacterium Escherichia coli, the Gram-positive bacterium Staphylococcus aureus, and the yeast Candida albicans has been investigated using a range of different methods. As antimicrobial, tea tree possess high inhibitory antifungal activity because of its components such as terpinen-4-ol, α-terpineol, linalool, α-pinene, β-pinene, and β-myrcene followed by 1,8-cineole. Bioactive compounds such as α-terpinene, α-terpinolene, and γ-terpinene shows high antioxidant activity of tea tree. Also, tea tree with its components are known to possess bacteriostatic and germicidal properties and are used to cure infections of the skin and mucous membranes such as boils, abscesses and onychomycosis caused by Candida. Their apparent insecticidal and acaricidal properties have to date been tested on some human ectoparasites such as head lice and Sarcoptes scabiei, var. hominis, and in recent time tea tree extracts were used in research for controlling ticks (Ixodes ricinus) that are efficient vectors of pathogens.
