Importance:

Sclerocarya birrea is an economically and culturally important African tree, valued for products such as Amarula Cream Liqueur, cosmetic oil, and its traditional medicinal uses, while also supporting rural livelihoods. Its drought tolerant and deep rooting system make it important in agroforestry and ecosystem resilience. Sequencing its genome will improve understanding of its biology, support conservation and breeding efforts, and enhance sustainable commercial development.

Species Card Details

Importance:

The species is a widely used medicinal plant in South Africa, well known for its immune-boosting properties. The rootstock is used to treat tuberculosis, urinary tract infections, prostate issues, rheumatoid arthritis and depression. Key compounds include hypoxoside, which converts to rooperol and sitosterol. However, raw forms contain toxic compounds. The species is heavily harvested, with unsustainable trade and habitat loss threatening the wild population. Conservation efforts are needed to protect this valuable species.
