Introduction: Medicinal herbs Acorus calamus, Curcuma longa, Zingiber officinale, and Piper betle have been traditionally used for treating stomach-related conditions such as irregular bowel movement, bloating, and gastric ulcers. The present study aimed to explore current status, research trends, and future directions of these herbs as functional herbal teas in prevention and treatment of gastritis. Methods: A total of 80 articles from Scopus database were retrieved and reviewed. Research trends were quantitatively analysed using VOSviewer software, focusing on the keywords, authors, countries, journals, and documents. A narrative review was integrated to provide comprehensive insights into the study. Results: Analysis revealed China and India as driving forces of this specific area of research, with the Journal of Ethnopharmacology emerging as a prominent source for publications in this field. “Curcumin”, “ginger”, and “Helicobacter pylori” were the main keywords of the study. Several gastroprotective mechanisms, including stimulation of mucosal proliferation, regulation of gastric acid production, reduction of inflammation in the gastric mucosa, protection of the gastric mucosa from oxidative damage, and inhibition of the growth of H. pylori, were associated with these herbs. Active compounds, such as α-asarone, curcumin, gingerol, and piperbetol, were found to be responsible for these effects. Conclusion: This study highlights various gastroprotective properties of A. calamus, C. longa, Z. officinale, and P. betle, providing researchers with a deeper understanding of the subject matter and opening new avenues for potential development into a functional herbal tea formulation known as “Lega Tea” (Relief Tea).

Background: Tumor-infiltrating neutrophils and lymphocytes play essential roles in promoting or combating various neoplasms. This study aimed to investigate the association between tumor-infiltrating neutrophils and lymphocytes and the neutrophil-to-lymphocyte ratio in the progression of urothelial carcinoma. Methods: A total of 106 patients diagnosed with urothelial carcinoma were was. Pathological examination for tumor grade and stage and for tumor-infiltrating neutrophils, both CD4 and CD8+ T lymphocytes, as well as the neutrophil- to-lymphocyte ratio were evaluated. Results: The presence of neutrophils and the neutrophil-to-lymphocyte ratio correlated with high-grade urothelial neoplasms. In both low- and high-grade tumors, the lymphocytes increased during progression from a non-invasive neoplasm to an early-invasive neoplasm. CD8+ T lymphocytes increased in low-grade non–muscle-invasive tumors compared to non-invasive tumors. Additionally, there was a significant decrease in CD8+ T lymphocytes during progression to muscle-invasive tumors. Conclusions Our results suggest that tumor-infiltrating neutrophils and CD8+ T lymphocytes have a significant effect on tumor grade and progression.
