Corymbia Citriodora is a tall tree, growing to 35 metres in height, from temperate and tropical north eastern Australia. It is also known as Lemon - Scented Gum, Blue Spotted Gum, Lemon Eucalyptus and Eucalyptus Citriodora.
Corymbia Citriodora has smooth, pale, uniform or slightly mottled bark, white to coppery in summer, and a conspicuously narrow - leaved crown which smells strongly of Lemons. The bark is smooth for the entire height of the tree, often powdery, shedding in thin curling flakes.
Eucalyptus Citriodora is one of the most popular Eucalyptus trees grown throughout Melbourne in Australia, which is its native country. This species is believed to have originated from a restricted area of Queensland on the Tropic of Capricorn, and is now found growing throughout the world’s tropical climates.
There are many types of Eucalyptus used to distill oil. Oils high in Eucalyptol are used medicinally, and oils such as the Eucalyptus Lemon are used more in the fragrance industry. More recently it has become a popular addition to natural bug repellents.
Although large quantities of Eucalyptus Citriodora essential oil were distilled in Queensland during the 1950 and 1960, very little of this oil is produced in Australia today. The largest producing countries are now Brazil, China and India, with smaller quantities originating from South Africa, Guatemala, Madagascar, Morocco and Russia.
The essential oil of the Lemon-Scented Gum mainly consists of citronellal (80%), produced largely in Brazil and China.
In Brazil, leaf harvesting may take place twice a year, whereas most of the oil produced in India comes from smallholders who harvest leaves at irregular times, mostly depending on convenience, demand, and oil trading prices.
After collection, the leaves, stems and twigs are sometimes chipped before quickly loading into the still for extraction by steam distillation. Processing takes approximately 1,25 hours and delivers a yield of 1,0% to 1,5% of a colourless to pale straw coloured essential oil.
The odour is very fresh, Lemon-Citrus and somewhat reminiscent of Citronella oil (Cymbopogon Nardus), due to the fact that both oils contain high levels of the monoterpene aldehyde, citronellal.
