The 'Candlenut' ('''Aleurites moluccana'''), is a
tree in the family
Euphorbiaceae, also known as 'Candleberry', 'Indian walnut', 'Kemiri', 'Varnish tree' or 'Kukui nut tree'.
Its native range is impossible to establish precisely because of early spread by man, and the tree is now widely distributed in the New and Old World tropics. It grows to a height of 15-25 m, with wide spreading or pendulous branches. The
leaves are pale green, simple and ovate, or trilobed or rarely 5-lobed, with an acute apex, 10–20 cm long. The
nut is round, 4–6 cm in diameter; the
seed inside has a very hard seed coat and a high oil content, which allows its use as a candle (see below), hence its name.
Uses
★ The candle nut is similar (though "rougher") in flavor and texture to the
macadamia nut, which has a similarly high oil content. It is mildly toxic when raw.
★ The nut is often used cooked in
Malaysian and
Indonesian cuisine, where it is called ''buah keras'' or ''kemiri''. In
Java, it is used to make a thick sauce which is eaten with vegetables and rice.
★ Several parts of the plant have been used in traditional medicine in most of the areas where it is native. The oil is an irritant and
purgative and sometimes used like
castor oil. It is also used as a hair stimulant or additive to hair treatment systems. The seed kernels have a
laxative effect. In
Japan its
bark has been used on
tumors. In
Sumatra, pounded seeds, burned with charcoal, are applied around the navel for
costiveness. In
Malaya, the pulped kernels or boiled leaves are used in poultices for headache, fevers, ulcers, swollen joints, and
gonorrhea. In
Java, the bark is used for bloody
diarrhea or
dysentery.

''Aleurites moluccana'' flowers
★ In ancient
Hawaii, the nuts, named ''kukui'' were burned to provide light. The nuts were strung in a row on a palm leaf midrib, lit one end, and burned one by one every 15 minutes or so. This led to their use as a measure of time. One could instruct someone to return home before the second nut burned out.
★ In
Tonga, still nowadays, ripe nuts, named ''tuitui'' are pounded into a paste, ''tukilamulamu'', used as soap or shampoo.
★ Candle nuts are also roasted and mixed into a paste with salt to form a Hawaiian condiment known as ''inamona''. Inamona is a key ingredient in traditional Hawaiian ''poke''. It's the Hawaiian state tree.

Modern cultivation is mostly for the oil. In plantations, each tree will produce 30–80 kg of nuts, and the nuts yield 15 to 20% of their weight in oil. Most of the oil is used locally rather than figuring in international trade.
Mythology
In Hawaii the Candlenut tree is a symbol of enlightenment, protection and peace. Candlenut was considered to be the body form of
Kamapua'a, the pig god. One of the legends told about a woman who, despite her best efforts to please her husband, was routinely beaten. Finally, the husband beat her to death and buried her under a kukui tree. Being a kind and just woman, she was given new life, and the husband was eventually killed.
