(A) Effect of extracts of Phyllanthus niruri 100 µg/mL, Ononis spinosa 100 µg/mL, Solidago virga-aurea 150 µg/mL, Peumus boldus 200 µg/mL, and Epilobium angustifolium 250 µg/mL water extracts and Fluxonorm® 800µg/mL on 8-iso-prostaglandin (PG)F2α production in isolated rat prostates challenged with E. coli lipopolysaccharide (LPS: 10 µg/mL). ANOVA, p < 0.0001, post-hoc ***p < 0.001 vs. LPS group. (B) Effect of water extracts of P. niruri 100 µg/mL, O. spinosa 100 µg/mL, S. virga-aurea 150 µg/mL, P. boldus 200 µg/mL, and E. angustifolium 250 µg/mL water extracts and Fluxonorm® 800 µg/mL on prostaglandin (PG)E2 production in isolated rat prostate challenged with E. coli lipopolysaccharide (LPS: 10 µg/mL). ANOVA, p < 0.0001, post-hoc ***p < 0.001 vs. LPS group.
