If you have looked into the Gorilla Flow formula, you've probably noticed Gorilla Cherry listed front and center. Here is what that ingredient actually is, the research behind it, and why it sits at the heart of a serious men's prostate health supplement.
"Gorilla Cherry" is the marketing name for Prunus Africana — also known as Pygeum africanum or African plum. It is an evergreen tree native to the mountainous regions of central and southern Africa, traditionally used by local populations for centuries to support men's urinary and prostate health.
The active part of the plant is the bark, which contains a mix of phytosterols (especially beta-sitosterol), pentacyclic triterpenes, and ferulic esters. These compounds are what researchers have studied for their potential effects on prostate tissue and urinary function.
Most prostate supplements lean heavily on saw palmetto. Gorilla Flow takes a different angle — Prunus Africana sits at the heart of its formula because of the depth of research on its specific compounds and their relationship with the lower urinary tract.
A Cochrane systematic review by Wilt et al. analyzed the available randomized controlled trials of Pygeum for benign prostatic hyperplasia. The review found that men taking Pygeum were more than twice as likely to report an overall improvement in symptoms compared to placebo, with adverse effects similar to placebo (PMID: 11869585).
That kind of evidence base — a published Cochrane review — is rare in the supplement world. It is what makes Prunus Africana stand out among plant-based prostate ingredients.
The exact mechanism is still being researched, but several pathways have been proposed in the literature:
This is why Gorilla Flow describes Prunus Africana as a "dual-pathway" ingredient — it appears to support both inflammatory and hormonal aspects of prostate health.
Benign prostatic hyperplasia (BPH) — non-cancerous enlargement of the prostate — affects most men by their 60s. The hallmark symptoms include nighttime urination, weak stream, hesitancy, and a sense of incomplete emptying.
Research on Pygeum and BPH spans decades. Smaller trials going back to the 1970s reported symptomatic benefits, and these were updated and analyzed in the Cochrane review mentioned above. While the methodological quality of older trials varies, the overall direction of evidence has been favorable for symptomatic support.
The phytosterols central to Pygeum's mechanism have themselves been the subject of major clinical research. A multicenter randomized trial published in the Lancet reported that beta-sitosterol — a key phytosterol in Pygeum — was associated with improvements in urinary symptom scores compared to placebo in men with BPH (PMID: 7791519).
It is important to note: Pygeum is not a treatment for BPH in the medical sense. It is a dietary supplement that may support healthy urinary function. Men with diagnosed BPH should work with a urologist for medical management.
Both ingredients have a history of use in men's prostate supplements. The two have different mechanism profiles:
This is part of why Gorilla Flow combines both, alongside four other ingredients. The idea is to support multiple pathways simultaneously rather than relying on one mechanism. For a deeper dive, read our comparison of Gorilla Flow vs saw palmetto.
In the published clinical research, Prunus Africana has demonstrated a side effect profile similar to placebo. The most commonly reported issues — when they occur — have been mild gastrointestinal upset.
That said, anyone taking blood thinners, prescription prostate medications, or who has a known allergy should consult a physician before starting any new supplement. Pygeum is sourced sustainably in modern supply chains, addressing earlier conservation concerns about the species in the wild.
If you are evaluating Pygeum-based products, watch for:
Gorilla Flow checks all of these boxes — its Prunus Africana sits alongside five other complementary ingredients in capsules made in an FDA-registered U.S. facility.
Yes. "Gorilla Cherry" is the marketing name used by Gorilla Flow for Prunus Africana, which is also commonly known as Pygeum africanum or African plum.
Most published studies have used courses of 6 to 8 weeks before evaluating outcomes. Many men report noticing changes between weeks three and six of daily use. Plant-based ingredients tend to build effects gradually rather than producing dramatic overnight changes.
Speak with your doctor first. Pygeum may have additive effects with medications that influence prostate or hormonal pathways. A healthcare professional is the right person to evaluate your full situation.
