Evaluation Of Anti-Inflammatory and Analgesic Activity Using Herbal Extracts of Ziziphus trinervia and Sagittaria trifolia

AbstractBackground: Chronic pain and inflammatory conditions pose significant global health challenges, often requiring long-term pharmacological interventions that carry potential side effects. Traditional medicine offers a rich source of potential natural alternatives; however, the precise mechanisms and efficacy of certain remedies require rigorous scientific validation. This study investigates the therapeutic potential of two such plants: Ziziphus trinervia and Sagittaria trifolia. Objective: This research project aimed to systematically evaluate the analgesic (pain-relieving) and anti-inflammatory capabilities of ethanolic extracts derived from Ziziphus trinervia and Sagittaria trifolia, employing both in vivo animal models and in vitro biochemical analyses to understand their mechanisms of action. Methods: The study utilized albino Wistar rats, allocated into nine distinct treatment groups for efficacy testing. Anti-inflammatory activity was assessed using the established Carrageenan-induced paw edema assay. Analgesic effects were quantified through the Eddy’s hot plate test. Gas Chromatography-Mass Spectrometry (GC-MS) was deployed to profile the phytochemical composition. Additionally, various inflammatory mediators, including specific interleukins (IL-1, IL-6, IL-8), cytokines, histamine, and prostaglandin E2 (PGE2), were measured to understand the extracts’ influence on inflammatory pathways. Results: The findings confirmed that the ethanolic extracts of both Ziziphus trinervia and Sagittaria trifolia elicited potent, dose-dependent anti-inflammatory and analgesic responses. The extracts effectively mitigated swelling in the edema model and significantly elevated the pain threshold in treated animals. GC-MS data identified a spectrum of bioactive compounds, such as flavonoids and specific fatty acids, hypothesized to be responsible for these pharmacological outcomes. Conclusion: The results robustly support the traditional use of Ziziphus trinervia and Sagittaria trifolia. The extracts exhibit substantial therapeutic potential as natural anti-inflammatory and pain-management agents. This work establishes a foundation for future research aimed at isolating lead compounds and exploring potential clinical applications for managing inflammatory conditions in humans.
