Hawaiian Name(s): kukui, kuikui

Scientific Name: Aleurites moluccana

Vernacular Name: candlenut, tung tree

Description: Trees, to 25 m tall, silvery-gray powder on leaves.

Habitat Common in mesic valleys especially between 0–700 m on most main islands (Wagner et al. 1990:598).

Medicines: For ‘ea and paa‘ao‘ao the flowers and endosperm (nut) of the kukui are combined with ‘ala‘alawainui pehu stems (Peperomia spp.), ‘ohi‘a ‘ai bark (Syzygium malaccense), ‘aka‘akai ‘oliana (?onion, Allium cepa) bulb, noni fruit (Morinda citrifolia), kō kea (white sugarcane, Saccharum officinarum), and possibly kikania (Desmodium sandwicense). Ingedients are mashed and strained, and liquid ingested. For infected sores, including puho ‘a‘ai, the green flesh of the kukui fruit is cooked in kī leaves (ti, Cordyline fruticosa) and combined with ‘ulu sap (Artocarpus altilis), powdered ‘ahu‘awa (Cyperus javanicus), and powdered lama (Diospyros spp.); the mixture is applied as a salve. For forms of kohepopo (ke‘a, kahaea, papaku, nae‘oiku, wai‘opua, hopilo, ni‘au) kukui bark is combined with the bark of ‘ohi‘a ‘ai and koa (Acacia koa), the leaf buds and stems of ‘ala‘alawainui pehu (Peperomia spp.), the leaves, flowers, and leaf buds of ko‘oko‘olau, kohekohe (Eleocharis spp.), noni fruits, root bark of the ‘uhaloa (Waltheria indica), root bark of the pōpolo (Solanum amerricanum), and kō kea (white sugarcane, Saccharum officinarum). For pu‘ao pehu the "shell" (endocarp) is burned and the smoke is used from inside an ipu.To build strength after an illness the endocarps (nut meat) are ground, along with cooked kalo (taro, Colocasia esculenta), the flesh of kikawaioa (fern, Christella cyatheoides), these are eaten with fish and ‘uala poi (sweet potato, Ipomoea batatas) with a ko‘oko‘olau infusion. As a purge, the oil of the kukui endocarp is used, and followed by poi and pia (Tacca leontopetaloides) (Chun 1994:170–174).

Non Medicinal Uses: The light-weight wood can be used for canoes (Abbott 1992:81; Malo 1951:21); the bark for dye and fruits and oil for light (Hillebrande 1888:400); "nuts" (oily endosperm) placed inside bamboo as torch (kali kukui) or oil burned in lamps (Abbott 1992:77), fish floats from wood (Degener 1930:197), oil for fishing, polishing; soot collected on smooth, clean pebbles under which kukui nuts had been burned for tattooing (Abbott 1992:128; Handy et al. 1972:232), dye also from the fleshy part of the green part of fruit also for tattooing (not as good), the "meat" of the seed (endosperm) roasted and eaten as 'inamona relish (Handy et al. 1972:231); endosperm also used in fish bait (Abbott 1992:85; Krauss 1993:45); sap as adhesive (Abbott 1992:120; Degener 1930:77), the oil as a polish (Krauss 1993:22), oil used to clean birdlime from bird's feet (Degener 1930:290), sticks burned in divining ceremony (Degener 1930:199). Used for hula altars (Pukui 1942); "nuts" for lei (Krauss 1993:79); wood for house timbers (Handy et al. 1972:232). In the Ethnology Collection at Bishop Museum there are examples of kukui oil used to make kapa waterproof and there is a post-contact example of the wood made into a bowl.
