Overview
About Kukui nuts
Kukui is the Hawaiian name for the nut of Aleurites moluccanus, the state tree of Hawaii and the same nut sold across Southeast Asia as a curry-paste thickener.
The thing to know first is that raw kukui is not food. The kernel contains phorbol esters and saponins that act as a violent purgative, and Hawaiian tradition used one or two roasted nuts deliberately as a laxative. Roasted and pounded into salt it becomes inamona, the classic seasoning for poke. On the trigger grades kukui reads like other oily nuts: high in nickel, borderline for oxalate and fermentability, and otherwise low in histamine, low in lectins and rated anti-inflammatory.

How Kukui nuts scores
Watch for
What trips people up
- Raw kukui is toxic, not merely unpleasant. Phorbol esters of the tigliane type are powerful cathartics, and ingesting raw kernels brings on nausea, cramping abdominal pain, vomiting and heavy diarrhoea, with dehydration and electrolyte loss if enough is eaten
- Even properly roasted, kukui stays laxative in quantity. A pinch of inamona on poke is the traditional dose. Eating them by the handful the way you would eat macadamias is where people get into trouble
- High in nickel, which is the one grade that behaves like an ordinary food trigger here and matters if you are managing systemic nickel allergy
- Borderline for oxalate and for SIBO, so it counts toward those budgets, though the portions kukui is normally eaten in are small enough that this rarely leads
- Beware weight-loss capsules and slimming teas sold as candlenut or nuez de la India. They rely on the raw nut precisely for its purgative effect and have caused serious poisoning

FAQ
Common questions about Kukui nuts
Are kukui nuts poisonous?
Raw ones effectively are. The kernel contains phorbol esters and saponins that irritate the gut aggressively, producing nausea, cramping, vomiting and profuse diarrhoea, and larger amounts cause dangerous fluid and electrolyte loss. Roasting or cooking is what makes them edible, and the pressed oil sold for skin care is not intended to be swallowed. The nuts sold online as nuez de la India for weight loss are this same raw nut being used for its purgative effect.
Why do kukui nuts cause diarrhoea even when they are cooked?
Because roasting reduces the purgative compounds rather than removing them entirely, and kukui is very high in oil on top of that. Hawaiian practice used one or two roasted nuts as a deliberate laxative, which tells you how little it takes. As a seasoning it is fine: inamona is roasted kukui pounded with salt and used in small pinches on poke, and in Indonesian and Malaysian cooking the nut is ground into a spice paste and cooked through, so a single portion contains very little.
Is kukui the same thing as candlenut?
Yes, the same tree and the same nut. Kukui is the Hawaiian name, candlenut is the English one and comes from the traditional use of the oily kernels strung on a stick as a lamp, and it is kemiri in Indonesian and buah keras in Malay. Recipes calling for candlenut and Hawaiian recipes calling for kukui are asking for the same ingredient.
Is kukui safe if you have a tree nut allergy?
Nobody can promise that. Botanically kukui is in the spurge family alongside cassava and castor, so it is not related to walnut, almond, cashew or pecan, and cross-reactivity is not predictable in either direction. Because it appears in Southeast Asian curry pastes that are rarely labelled clearly, anyone with a nut allergy should treat candlenut as an unknown and clear it with their allergist rather than assuming the botanical distance protects them.
