Plant Description:
Melaleuca alternifolia, commonly known as tea tree is a species of tree or tall shrub in the myrtle family, Myrtaceae. Endemic to Australia, it occurs in southeast Queensland and the north coast and adjacent ranges of New South Wales where it grows along streams and on swampy flats, and is often the dominant species where it occurs.
Melaleuca alternifolia is a small tree that can grow to about 7 m (20 ft) with a bushy crown and whitish, papery bark. The leaves are arranged alternately, sometimes scattered or whorled. The leaves are smooth, soft, linear in shape, 10–35 mm (0.4–1 in) long, and 1 mm (0.04 in) wide. They are also rich in oil with the glands prominent. Flowers occur in white or cream-colored masses of spikes 3–5 cm (1–2 in) long over a short period, mostly spring to early summer, and give the tree an appearance of looking fluffy. The small, woody, cup-shaped fruit, 2–3 mm (0.08–0.1 in) in diameter, are scattered along the branches.
Tea tree is grown in plantations in northern New South Wales and south east Queensland. Plantation trees are planted in rows and kept to a maximum height of 4 metres. They are machine harvested and steam distilled immediately to obtain the highest quality Tea Tree essential oil.

Tea Tree Oil Uses:
Traditional Usage; Indigenous people would traditionally heat rocks in their fires until they got extremely hot. These hot rocks were then place into small pools of water, creating steam. The Tea Tree leaves and branchlets were place into the steaming water vapour and the oil vapour was then inhaled for respiratory conditions.
Leaves and small branchlets were ‘stuck’ onto affected areas of the body with wet mud similar to a compress.
Early European usage; In the early 1900s there were several small-scale distillations plants utilising wild tree populations, particularly around northern New South Wales. When antiseptics were in short supply during World Wars 1 and 2, soldiers were issued with Tea Tree oil as part of their first aid kit.
Present day usage; In the 1970’s interest in Tea Tree oil was restarted by the Dean family, just south of Byron Bay. Tea Tree oil is now known around most of the world. In the 1980’s and 90’s many Tea Tree oil plantations were established in the northern New South Wales region. Essentially Australia prides itself on sourcing its Tea Tree essential oil directly from local northern New South Wales Tea Tree farmers. These farmers have been long involved with the Tea Tree industry and their expertise and quality is second to none, please see our video above.
Precautions
Ginger oil is non-toxic and non-irritant (except when used in high concentrations) but could irritate sensitive skins and can also cause photosensitivity.
Keep out of reach of children. If you are pregnant, nursing, or under a doctor’s care, consult your physician. Avoid contact with eyes, inner ears, and sensitive areas.
