Product Abstract
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.
History
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.
Harvesting/Extraction Information
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.
