***Calophyllum inophyllum*** is a large evergreen plant, commonly called **Alexandrian laurel** **balltree**, **beach calophyllum**, **beach touriga**, **beautyleaf**, **Borneo-mahogany**, **Indian doomba oiltree**, **Indian-laurel**, **laurelwood**, **red poon**, **satin touriga**, [//en.wikipedia.org/wiki/Cambodia Cambodia]; [//en.wikipedia.org/wiki/China China] (on [//en.wikipedia.org/wiki/Hainan Hainan]); southern India; Andaman and Nicobar Islands [//en.wikipedia.org/wiki/Indonesia Indonesia]; [//en.wikipedia.org/wiki/Japan Japan] ([//en.wikipedia.org/wiki/Ryukyu_Islands Ryukyu Islands]); [//en.wikipedia.org/wiki/Malaysia Malaysia]; [//en.wikipedia.org/wiki/Myanmar Myanmar]; [//en.wikipedia.org/wiki/Papua_New_Guinea Papua New Guinea]; the [//en.wikipedia.org/wiki/Philippines Philippines]; [//en.wikipedia.org/wiki/Sri_Lanka Sri Lanka]; [//en.wikipedia.org/wiki/Taiwan Taiwan]; [//en.wikipedia.org/wiki/Thailand Thailand]; [//en.wikipedia.org/wiki/Vietnam Vietnam]; the northwestern, southwestern and south central Pacific Region in: the [//en.wikipedia.org/wiki/Cook_Islands Cook Islands]; [//en.wikipedia.org/wiki/Fiji Fiji]; [//en.wikipedia.org/wiki/French_Polynesia French Polynesia] ([//en.wikipedia.org/wiki/Marquesas_Islands Marquesas] and [//en.wikipedia.org/wiki/Society_Islands Society Islands]); [//en.wikipedia.org/wiki/Guam Guam]; the [//en.wikipedia.org/wiki/Marshall_Islands Marshall Islands]; [//en.wikipedia.org/wiki/Micronesia Micronesia]; the [//en.wikipedia.org/wiki/Northern_Mariana_Islands Northern Mariana Islands]; [//en.wikipedia.org/wiki/Palau Palau]; and [//en.wikipedia.org/wiki/Samoa Samoa]; and in Australia in: [//en.wikipedia.org/wiki/Northern_Territory Northern Territory] and [//en.wikipedia.org/wiki/Queensland Queensland]. The nuts are dried before cracking, after which the oil-laden kernel is removed and further dried. The first [//en.wikipedia.org/wiki/Neoflavone neoflavone] isolated from natural sources (1951) was [//en.wikipedia.org/wiki/Calophyllolide calophyllolide] from *C. inophyllum* seeds.

The [//en.wikipedia.org/wiki/Mavilan Mavilan], a [//en.wikipedia.org/wiki/Tulu_language Tulu]-speaking tribe in north [//en.wikipedia.org/wiki/Kerala Kerala] in India, use the bark to make a powder that they mix with water and apply it to plants affected by a type of plant disease caused by water that they call *neeru vembu*.

The sap of the tree is poisonous and is used to make poison arrows in Samoa. The mature fruit is poisonous enough to use as rat bait.

The [//en.wikipedia.org/wiki/Fatty_acid_methyl_ester fatty acid methyl esters] derived from [//en.wikipedia.org/wiki/Calophyllum_inophyllum_seed_oil *C. inophyllum* seed oil] meets the major [//en.wikipedia.org/wiki/Biodiesel biodiesel] requirements in the [//en.wikipedia.org/wiki/United_States United States] ([//en.wikipedia.org/wiki/ASTM_International ASTM] D 6751), and [//en.wikipedia.org/wiki/European_Union European Union] ([//en.wikipedia.org/wiki/European_Committee_for_Standardization EN] 14214).  The average oil yield is 11.7&nbsp;kg-oil/tree or 4680&nbsp;kg-oil/hectare.  In the northwest coastal areas of Luzon island in Philippines, the oil was used for night lamps.  This widespread use started to decline when kerosene became available, and later on electricity.  It was also used as fuel to generate electricity to provide power for radios during World War II.

The tree is regarded as sacred in some Pacific islands because of its excellent growth in sandy soil as shade tree and many uses. The 1889 book 'The Useful Native Plants of Australia records that "During a debate on the Pearl Fisheries Bill in the Queensland Assembly, a clause was specially inserted to protect trees of this species at Thursday Island. A fine of £10 is inflicted on any person who cuts down or injures this or a cocoa-nut tree, or any other tree bearing edible fruit. This clause is, of course, in the
interest of the aboriginals.".
