Marula oil is extracted from the kernels (nuts) of the fruits of the Marula trees (Sclerocarya birrea), from the Anacardiaceae family. There are two types of Marula oil, the oil extracted from the seeds and the oil extracted from the nut's hard shell. Marula oil is traditionally used in cosmetics, in food as a cooking oil and as a meat preservative and to treat leather.

The Tsonga people of South Africa and Mozambique have used the oil as a moisturising body lotion for women and also as a massage oil for babies. In the past, women used Marula oil rather than water to clean themselves.
Marula oil forms also an important part of people's diets, especially for people of the Inhambane Province in Mozambique, Owambo in north central Namibia, Northern KwaZulu-Natal in South Africa and the Zvishavane district of Zimbabwe. Furthermore, marula plays an important role in the diet of Bushmen and Bantu tribes. The Venda use the oil from the kernels to preserve meat, which enables it to last up to a year. Today, Marula oil is still considered a delicacy by local people, and is added to a wide variety of traditional and modern recipes.
