Yellow Star

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.
