ある研究結果 (Mehrotra et al., 2011) found that the extract of amla pulp had anti-H. pylori activity against different strains of H. pylori that were resistant to different antibiotics. The extract also retained its antioxidant properties even after being exposed to high temperatures and acidic conditions. This suggests that amla could protect the stomach lining from oxidative damage and inflammation caused by H. pylori.
