Cajeput tree is related to the tea tree as they are from the same genus, Melaleuca. It can be found close to shorelines on the island of Pulau Buru in Maluku and in some parts of Central Java. Cultivation is not needed as removing a tree creates rapid re growth of the tree and it tends to crowd out all other trees in the area.
Primarily used in massage oils, it is also used for its remedial qualities in treating stomach aches, common cold, nausea and insect bites. More than 90% of the oil produced is consumed locally by the pharma industry. Cajeput has been known to be used to overcome a lack of energy and renew a zeal for life.
It is known in ancient India as Kayaputi and was also revered in the East for all its uses. Cajeput has stood tall and is a time tested remedy for respiratory and sinus related infections since thousands of years.
Cajeput is a small tree with a soft, thick, spongy, ash-colored bark and scattered branches, with the slender twigs often drooping likethe weeping willow (Salix babylonica). The leaves are from 3 to 5 inches long, and very aromatic when bruised. An evergreen, vigorous growing tree, it can reach 30 meters (98 feet) and has a whitish spongy bark with a crooked trunk.
Cajuput essential oil is extracted from fresh leaves and twigs by steam distillation.
Although no serious threats are found to be associated with this oil, ingestion of a large quantity or application in highly concentrated form may still cause irritation. Therefore, only low or mild doses should be administered.

Adverse skin reactions Undiluted cajuput oil was not irritating to the skin of rabbits, mice or pigs; tested at 4% on 25 volunteers it was neither irritating nor sensitizing. It is non-phototoxic. 1,8-Cineole presents a low risk of both skin irritation and sensitization.
Reproductive toxicity The low reproductive toxicity of 1,8- cineole, (þ)-limonene, linalool and a-pinene suggests that cajuput oil is not hazardous in pregnancy.
Acute toxicity (human) 1,8-Cineole has been reported to cause serious poisoning in young children when accidentally instilled into the nose.
Acute toxicity (animal) Cajuput oil acute oral LD50 in rats 3.87 g/kg; acute dermal LD50 in rabbits >5 g/kg .
Carcinogenic/anticarcinogenic potential No information found. 1,8-Cineole is non- mutagenic and shows no evidence of carcinogenesis in rodents.
