    Tea tree oil: What can it do for your patients?

    Tea tree oil is an essential oil that is obtained through steam distillation of the leaves of the native Australian coastal tree, Melaleuca alternifolia. M. alternifolia is an evergreen shrub with needle-like leaves that grows from 5 to 8 meters in height. Tea tree oil has been used in a wide variety of medicinal applications from coughs and colds to skin infections.1 Relevant to dermatology, tea tree oil can be found in over-the-counter soaps, astringents and shampoos and is typically added to these products for its antimicrobial properties.
