Candlenut is the seed of the fruit produced by the candlenut tree (Aleurites moluccanus). The seed, seed oil, and kernel have sometimes been used as medicine.

While candlenuts resemble walnuts in appearance, candlenuts are extremely poisonous, even deadly, if they are eaten raw or undercooked. Candlenut contains various substances that might stimulate the bowels and cause sweating. It also contains toxic chemicals, such as cyanide.

People use candlenut for asthma and constipation and to encourage hair growth, but there is no good scientific evidence to support these uses. Using candlenut can also be unsafe.
When taken by mouth: Candlenut is unsafe. It contains a chemical similar to cyanide as well as other poisons. Even one seed might cause severe poisoning. Candlenut can cause extreme stomach pain, violent vomiting, breathing problems, and possibly death.

When applied to the skin: There isn't enough reliable information to know if candlenut is safe or what the side effects might be.

Pregnancy and breast-feeding: It's unsafe for anyone to take candlenut by mouth. If you are pregnant or breast-feeding, it could harm you as well as your baby.
