It is characterized by symptoms such as abdominal discomfort, bloating, and nausea, which can significantly impact a person's quality of life. While there are several pharmaceutical treatments available, many individuals are turning to herbal remedies as a safer and more natural alternative. This clinical study aimed to evaluate the efficacy and safety of poly-herbal formulation (PHF), marketed under brand names like Dizester® Herbal, Great Day®, etc. in patients suffering from functional dyspepsia compared to Pantoprazole, a commonly used pharmaceutical treatment.</div></div><div><h3>Materials &amp; Methods</h3><div>The study included 80 patients, with 40 patients in each treatment arm. The primary objective was to assess the improvement in symptoms using various questionnaires at All India Institute of Medical Science Bhubaneswar, including the Reflux Disease Questionnaire, Short-Form Leeds Dyspepsia Questionnaire, GERD-Health Related Quality of Life Questionnaire, visual analogue scale (VAS) for pain, and Investigator's Symptomatic Assessment. The secondary objective was to evaluate the safety of PHF by assessing liver and renal function parameters and hemogram.</div></div><div><h3>Results &amp; discussion</h3><div>The results showed significant improvement in symptoms of GERD in the PHF group, which was comparable to the Pantoprazole group. The burning feeling behind the breastbone, pain behind the breastbone, burning feeling in the center of the upper stomach, acid taste in the mouth, and unpleasant movement of material upwards towards the mouth improved significantly from the beginning of the study to the follow-up visits. The mean VAS score reduced by 71.5 % in the PHF arm and 67.85 % in the Pantoprazole arm. Additionally, the study found no abnormal elevations in liver and renal function parameters in blood or any abnormal changes in hemogram, indicating the safety for use in patients with functional dyspepsia. Since the synthetic anti-dyspeptic drugs like proton pump inhibitors are known to have adverse effects, this natural alternative PHF shows promising results in a safer way.</div></div><div><h3>Conclusion</h3><div>In conclusion, this study provides evidence for the efficacy and safety of PHF in improving symptoms of functional dyspepsia. The use of synthetic anti-dyspeptic medications has been associated with the occurrence of undesirable effects. In light of this, PHF has demonstrated encouraging outcomes in a manner that is considered safer.</div></div>","PeriodicalId":34599,"journal":{"name":"Phytomedicine Plus","volume":"5 1","pages":"Article 100671"},"PeriodicalIF":0.0,"publicationDate":"2024-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142723892","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Black, green, and purple teas, renowned for their antioxidant properties, exhibit efficacy against various cancers, including prostate cancer.</div></div><div><h3>Study Design</h3><div>This was an experimental study conducted from the Kenya Medical Research Institute (KEMRI).</div></div><div><h3>Aim of the Study</h3><div>the present study aimed to evaluate the Cytotoxic effect of black, green and purple teas against prostate cancer cell line DU-145 and in silico prediction of Tea catechins interaction with prostate cancer proteins such as 3D-crystal structures of Androgen-receptor(5T8E) and Human p38 MAPK(1KV2).</div></div><div><h3>Methods</h3><div>The study started by quantifying tea catechins (Epigallocatechin gallate (EGCG), Epigallocatechin EGC, Epicatechin gallate (ECG) and Epicatechin (EC) with high-liquid chromatography (HPLC), cytotoxicity analysis of black, green and purple tea crude extracts against DU-145 cell line at 24hr and 48 hrs by Resazurin assay and molecular docking was performed with Autodock Vina 1.1.2 software.</div></div><div><h3>Results</h3><div>EGCG appeared the most predominant catechin with 552.2 ± 10.61 (mg g^-1 DW) while EC was the lowest detected with 118.08 ± 9.45 (mg g^-1 DW). Purple tea extract exhibited high antiproliferative activity with IC50 of 98.69±1.99 µg/ml at 24hr and 91.21±6.91 µg/ml at 48hr, green tea followed with 121 ± 5.97µg/ml at 24hr and 107.1 ± 2.03 µg/ml at 48hr IC50; black tea was the least effective tea at both 24hr and 48hr with IC50 of 290.8 ± 2.46µg/ml and 237.8 ± 5.59µg/ml respectively. Prediction of catechin target genes and Prostate cancer (Pca)-related genes discovered 121 catechin target genes and 34,926 Pca-related genes. EGC exhibited high binding interaction to 5T8E with the lowest affinity of -9.1Kcal/mol followed by EGCG at -8.4 (Kcal/mol then EC with -8.2 (Kcal/mol) and EGC at -8.1 (Kcal/mol).
