Melaleuca cajuputi, also known as cajuput or white samet, is a plant of the Myrtle family, Myrtaceae, widely distributed in Australia, Southeast Asia, New Guinea and the Torres Strait Islands. It is a medium to tall tree with papery bark, silvery buds, and white or green flower spikes. It has important uses as a source of cauliflower oil.
In Southeast Asia, Melaleuca is used as fuel and to make charcoal. It is used on a small scale in house construction to support columns, frames and floors, as well as for fences. The bark has been used as roofing material and as a sealant in ship construction, including as caulking material for ships in Indonesia.
Australian Aboriginals used the leaves of this species to treat pain and inhaled the vapor from crushed leaves to treat respiratory infections. In Thailand, the leaves are used to make herbal tea to treat a range of medical problems. In many parts of Asia, oil of the jade tree, for which the tree is named, is used as a liniment and inhalant.
