Carissa macrocarpa (Natal Plum), is a shrub native to South Africa, where it is commonly called the Large Num-Num. In Zulu, as well as in the Bantu tribes of Uganda, it is called Amathungulu or umThungulu oBomvu. In Afrikaans the fruit is called Noem-Noem. A traditional food plant in Africa, this little-known fruit has potential to improve nutrition, boost food security, foster rural development and support sustainable landcare.
