Study showed an inhibitory effect of P niruri extract on CaOx crystal growth and aggregation in human urine, suggesting an interference with the early stages of stone formation and presents an alternative form of treatment and / or prevention of urolithiasis. (11)
• Antihyperuricemic Effect:
Study showed the methanol extract of P niruri and its lignans were able to reverse the plasma uric acid of hyperuricemic animals. The effect could be through its uricosuric action and partly through xanthine oxidase inhibition. The antihyperuricemic effect of the lignans was attributed to their uricosuric action. A methanol extract of leaves showed dose-dependent oral antihyperuricemic activity in potassium oxonate- and uric acid-induced hyperuricemic rats. (12)
• Acute Toxicity Study / Leaf Extract Effect:

• Hepatoprotective Against Alcohol and Other Hepatotoxicants:
Study showed a hepatoprotective effect against alcohol and several hepatotoxicants. PN can potentially inhibit the transcription of pro-inflammatory cytokines (TNFa) produced by kupffer cells. The hepatoprotective effect is attributed to bioactive compounds such as lignans, alkaloids, terpenoids,and tannins, especially phyllanthin and hypophyllanthin, quercetrin, astragalin, gallic acid, elagic acid and corilagin.
Extracts of leaf, stem, root, and fruit were evaluated for antimicrobial activity. Ethanol, water, n-butanol extracts of leaf, stem and fruit parts were found to be effective against most of the human pathogenic microorganisms. (27)
• Anti-Lithiatic / Leaves:
In vitro study evaluated various extract for anti-urolithiatic effect with two standard drugs, Neeri and Cystone as control. Results showed the water extract of leaves to have anti-urolithiatic effect, equal to cystone in dissolving the exiting calcium oxalate crystals. A methanol extract was second in anti-lithiatic activity. (29)
