The two extract doses (300 and 600 mgkg) exhibited PSA reduction of 55.5% (4 ng/ml) and 55.5% (4 ng/ml), respectively; finasteride-treated rats showed 44.4% (5 ng/ml), while simultaneous extract administration with BPH induction for thirty days resulted in 55.5% (5 ng/ml). This evidence concerns the gene KLK3 and benign prostatic hyperplasia.
