Pygeum (African Plum Bark): Uses, Benefits, Dosage & Safety

Last updated: June 2026 · Reviewed by the FactoWiki Editorial Team for clarity and source accuracy

What is Pygeum (African Plum Bark)?

Pygeum comes from the bark of the African plum or African cherry tree (Prunus africana, formerly Pygeum africanum). It has traditional use in Africa for urinary problems and is marketed, often alongside saw palmetto, beta-sitosterol and stinging nettle, for the urinary symptoms of benign prostatic hyperplasia (BPH). Its components include phytosterols and fatty acids. Demand has led to overharvesting, making the tree a conservation concern and sustainable sourcing an ethical consideration.

What Pygeum (African Plum Bark) is commonly used for

In supplements, Pygeum (African Plum Bark) is most often included for prostate & men's urinary health support. It is used as nutritional support, not as a treatment for any medical condition — the distinction matters, because the claims on a sales page are often stronger than the evidence allows.

How Pygeum (African Plum Bark) works

Pygeum's phytosterols are proposed to have anti-inflammatory effects on prostate tissue and to influence growth factors involved in prostate enlargement, which is the rationale for its use in urinary symptoms. As with other prostate botanicals, the laboratory rationale is more developed than the high-quality clinical evidence.

What the evidence says

Here's an honest snapshot of what published research suggests about Pygeum (African Plum Bark) — including where the evidence is limited.

• An older systematic review suggested pygeum might modestly improve urinary symptoms and flow in BPH, but the included trials were small, short and methodologically weak. (PubMed research)
• More recent rigorous trials are scarce, so the evidence base remains limited and dated. (PubMed research)
• It is frequently studied and sold in combination with other prostate botanicals rather than alone. (PubMed research)

Typical dosage used in studies

Older trials commonly used about 100-200 mg/day of a standardised bark extract. This is research information, not a recommendation.

Side effects and safety

Pygeum is generally well tolerated; mild digestive upset, nausea or diarrhoea are the most commonly reported effects.

Frequently asked questions

Does pygeum help prostate symptoms?

Older, weak trials hinted at a modest benefit for BPH urinary symptoms, but the evidence is limited and dated, and rigorous modern trials are scarce.

How does it compare to saw palmetto?

Both are popular prostate botanicals with limited high-quality evidence; pygeum's trials are older and smaller. Neither is a substitute for medical assessment.

What dose was used in studies?

Around 100-200 mg/day of a standardised bark extract.

Is pygeum safe?

Generally well tolerated, with mild digestive effects the main complaint.

Is there an ethical concern?

Yes — the African plum tree has been overharvested, so choosing sustainably sourced pygeum matters.
