Abstract

Caryota urens L. is a widely cultivated plant often employed in traditional medicine for the treatment of various conditions such as arthritis, gastritis, skin disorders, blisters, and pain relief. Despite its common use, the anti-inflammatory effect ofC. urens fruit extract remains unproven and undocumented in scientific literature. This study assessed the anti-inflammatory effects of ethanol extract ofC. urens fruit and provide scientific evidence for the anti-arthritis herbal remedy. A rheumatoid arthritis model was induced by injecting complete Freund's adjuvant (0.1 mL) into the right hind paw of mice, and three doses of ethanol extract ofC. urens fruit (100, 200, and 300 mg/kg body weight) were administered for treatment. The severity of arthritis was evaluated through joint circumference and arthritis scores, as well as hematological and biochemical parameters (red blood cells, white blood cells, erythrocyte sedimentation rate, alkaline phosphate, C-reactive protein, and rheumatoid factor). The inflammatory and anti-inflammatory cytokines (TNF-α, INF-γ, IL-1β, IL-6, and IL-10) and histological changes in the joints were also examined. The results demonstrated a significant reduction in paw volume and arthritis scores with all three doses of the extract. Furthermore, theC. urens fruit extract exhibited the ability to modulate the interplay of inflammatory cytokines and mitigate the histological alterations induced by Freund's adjuvant. The effectiveness of the high dose (300 mg/kg body weight) was comparable to the Mobic (0.2 mg/kg body weight). In conclusion, this study elucidates the potential ofC. urens fruit extract in arthritis treatment, providing a scientific justification for it traditional use as a remedy for arthritis management.
