Which Rosaceae herb uses bark and has anti-inflammatory and antioxidant actions, used for BPH and urinary disorders?

• A. Prunus africana
• B. Tribulus terrestris
• C. Rhamnus frangula
• D. Selenicereus grandiflorus

Answer: (A)

Prunus africana stands out because it is a Rosaceae herb whose bark is the part most often used medicinally. The bark extract is known for anti-inflammatory and antioxidant activities, which align well with addressing prostatic inflammation and oxidative stress seen in benign prostatic hyperplasia and related urinary symptoms. Historical and contemporary herbal use of Prunus africana centers on improving urinary flow and reducing irritation in BPH, making it the best fit for the described actions and plant part.

The other plants listed come from different families or use different plant parts with different primary applications. Tribulus terrestris is a Zygophyllaceae plant used mainly for male reproductive health but not for bark-based anti-inflammatory urinary support. Rhamnus frangula (buckthorn) is a laxative and comes from the Rhamnaceae family, not associated with bark-driven BPH therapy. Selenicereus grandiflorus is a cactus and not a Rosaceae, with uses more aligned to sedative or cardiotonic contexts rather than bark-based urinary indications.
