Pygeum

Prunus africana, also known as the African cherry, is a tree native to montane regions in central and southern Africa and several islands including Bioko, São-Tomé, Grande Comore, and Madagascar. Traditionally, its bark has been used for a variety of medicinal purposes such as treating fevers, malaria, stomach pain, kidney disease, and other ailments. The bark extract, known as Pygeum, is marketed as a supplement for prostate health, particularly for benign prostatic hyperplasia (BPH). However, scientific evidence regarding its effectiveness is mixed and inconclusive. Some studies suggest potential benefits in relieving symptoms of BPH, while others, including a 2016 literature review, found no significant benefit. Pygeum is believed to work by interfering with growth factors and having an anti-androgenic effect, although more research is needed to confirm these effects in humans. Additionally, Prunus africana is rich in plant sterols, which are thought to be beneficial for prostate health. The tree, which can grow up to 20 meters high, is characterized by its almond-scented leaves, creamy-white flowers, and purplish-red cherries that turn black when ripe. Despite its medicinal properties, there are concerns about the sustainability of harvesting its bark, as overexploitation threatens the survival of the species.
