Aloe ferox, a cousin of aloe vera, is a succulent native to South Africa. It is a listed endangered plant species, along with other species of the same genus. Reaching a height of three meters, it grows on hillsides, in grassy fynbos areas and at the edges of deserts. The plant must be four to five years old before the first harvest. The adult leaves are hand-picked by local populations every 18 to 24 months, weighing an average of 1.5 to 2 kg. The whole plant is used for its active ingredients: the leaves are ground into powder, with recuperation of the resulting gel extract.
