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.
