ObjectiveThe increasing demand for natural, safe, and high-quality meat products has prompted interest in replacing synthetic preservatives with plant-based alternatives. This systematic review aimed to evaluate the effects of spice essential oils (SEOs) on the physicochemical, antimicrobial, antioxidant, and sensory properties of processed sausages.MethodsFollowing PRISMA guidelines, a comprehensive literature search was conducted in English databases from November 2007 to September 2025 and 54 relevant articles were selected based on predefined inclusion criteria.ResultsThe reviewed studies demonstrated that SEOs significantly improved the oxidative stability, microbial safety, and sensory quality of sausages. These essential oils can regulated pH and water activity during storage.ConclusionSEOs represent effective natural preservatives that can enhance the safety, stability, and sensory acceptability of processed sausages. Optimizing their concentration and application methods, alongside synergistic combinations with natural extracts or reduced nitrite levels, can provide a promising strategy for producing healthier meat products.

Background and aimsAntispasmodics and antidepressants are standard therapies for managing both the gastrointestinal symptoms and psychological comorbidities associated with irritable bowel syndrome (IBS). However, direct comparative evidence regarding their efficacy across different symptom domains is scarce. This systematic review and network meta-analysis aimed to assess the relative effectiveness of these agents on abdominal pain, psychological outcomes, overall IBS symptom severity, and quality of life (QoL).MethodsWe conducted a comprehensive search of PubMed, EMBASE, and Scopus to identify relevant randomized controlled trials evaluating antispasmodics and antidepressants for IBS. Eligible studies underwent quality assessment and were synthesized using network meta-analysis. We calculated standardized mean differences (SMDs) with 95% confidence intervals (CIs) for pain outcomes (VAS), anxiety, depression, the IBS Severity Scoring System (IBS-SSS), and QoL.ResultsTwenty-nine studies were included in the analysis. Significant reductions in pain (VAS) were observed with imipramine (SMD -34.06; 95%CI -51.89 to -16.22) and the alverine/simethicone combination (SMD -6.23; 95%CI -9.93 to -2.53), while mebeverine and anise oil showed benefits in specific IBS subgroups. The most substantial improvements in anxiety occurred with flupentixol-melitracen (SMD -6.63; 95%CI -10.13 to -3.13), followed by small-intestinal release peppermint oil, fluoxetine, and vortioxetine. Imipramine was most effective for depressive symptoms (SMD -9.40; 95%CI -10.29 to -8.51), followed by venlafaxine, flupentixol-melitracen, desipramine, and vortioxetine. Amitriptyline was the only agent to show significant improvement in IBS-SSS scores (SMD -23.70; 95%CI -43.27 to -4.13). The largest gains in QoL were associated with otilonium bromide (SMD 30.90; 95%CI 26.62 to 35.18), followed by venlafaxine, amitriptyline, and cumin sofouf.ConclusionsImipramine and alverine/simethicone were superior for reducing abdominal pain, whereas flupentixol-melitracen, peppermint oil, fluoxetine, and vortioxetine demonstrated the strongest anxiolytic effects. Effective options for depression included imipramine, venlafaxine, flupentixol-melitracen, desipramine, and vortioxetine. Notably, amitriptyline uniquely improved overall IBS severity scores, while otilonium bromide, venlafaxine, amitriptyline, and cumin sofouf provided the greatest benefits for QoL. These findings clarify comparative efficacy and may guide tailored pharmacotherapy strategies for IBS patients.

Irritable bowel syndrome (IBS) is a common disorder of brain-gut interaction that presents with abdominal pain, bloating associated with variable stool consistency. Many IBS patients prefer plant-based preparations to pharmacological therapy; however, the utility of this approach is not well established. To address this issue, a systematic review with meta-analysis to assess the efficacy and safety of plant-based therapy in IBS patients was performed. Literature search with 3 electronic databases (Medline via PubMed, Embase via Ovid, and Web of Science Core Collection) from inception to May 2024. Efficacy was assessed using dichotomous ratings of change in IBS symptoms. A random effects model with 95% confidence intervals was used. Through the screening process, 60 eligible studies were identified (6329 patients). Meta-analysis was performed for fiber (8 studies, RR = 1.22; 95% CI: 1.00-1.49), peppermint oil (7 studies, RR = 1.63; 95% CI: 1.33-2.00), Aloe vera (3 studies, RR = 1.25; 95% CI: 0.76-2.06), and Chinese herbal medicine (7 studies, RR = 1.56; 95% CI: 1.27-1.92). For other plant-based substances investigated in at least one randomized controlled trial (RCT) (e.g., St. John's wort, Anise oil), there were insufficient data for a meta-analysis. The quality of many studies was limited. The findings demonstrate that the treatment of IBS patients with peppermint oil and Chinese herbal medicine were more effective than placebo and had a good safety profile. Dietary fiber showed effects that approached significance. Further, well-powered RCTs are needed to establish the place of plant-based preparations in IBS treatment.

Illicium verum Hook. F., also known as star anise, is one of the most important plants of the genus Anise in the family Magnoliaceae. I. verum not only has the functions of warming Yang, dispersing cold, regulating Qi and relieving pain but can also be used as a condiment to increase flavor as well as reconcile and remove fish smells. Currently, 201 chemical constituents have been identified from star anise; among these, star anise oil and shikimic acid are the two most widely used and studied chemical components in star anise, with the oil accounting for a large proportion of the total. This review integrates, classifies and updates studies related to the botany, pharmacology, phytochemistry, traditional and modern uses and quality control of star anise, with a special reference to its phytochemical composition and pharmacological activity. It will provide a reference for further research on this important medicinal plant. In addition, the broad applications and research profiles of star anise essential oil and shikimic acid are highlighted. Our review indicates that the research prospects regarding star anise are very broad and worthy of further investigation.
