Analgesic and anti-inflammatory activity of aqueous extract of Bubonium graveolens

Abstract

Introduction: Bubonium graveolens is used in traditional pharmacopoeia against imbalances of the gastrointestinal tract, cephalic pains, and bronchitis, and as an anti-inflammatory agent.
 Methods: We have investigated the analgesic and anti-inflammatory activities of the aqueous extract of Bubonium graveolens in male mice of strain NMRI Albinos, weighing between 22 g and 38 g. Acetic acid was used to induce writhes in the mice and inflammation of paw edema.
 Results: Evaluation of the analgesic activity showed that the aqueous extract at 150 mg/kg of the plant induced a decrease in the number of abdominal cramps caused by 1% acetic acid. The aqueous extract of the plant had an analgesic effect almost equal to that of Diclofenac; in fact, the latter caused a pain inhibition of 49 ± 1.1% while Bubonium graveolens caused a pain inhibition of 49.6 ± 2.1%, at the concentration of 150 mg/kg. Evaluation of the percentage of inhibition showed that the aqueous extract of Bubonium graveolens had a better anti-inflammatory activity compared to Diclofenac sodium during the treatment duration (69.57% — 56.52% at 60 min; 71.43% — 50.00% at 120 min, and 75.00% — 66.67% at 180 min).
 Conclusion: The results of this research indicate that Bubonium graveolens inhibits inflammation and could explain its effective use in traditional medicine.

Preparation of Chitosan Nanoparticle from Crab Shells and Evaluation of ‎Analgesic and Anti-inflammatory Activities of Chitosan-loaded ‎Haematostaphisbarteri Hook. f. Stembark Extract

“…An acetic acid-induced abdominal writhing test was used to detect the peripheral analgesic effect of the stembark extract due to its ability to detect the analgesic activity of medicinal plants and other drugs at doses which remain inert for other assays (Fyad et al, 2020). The acetic acidinduced writhing test is a recommended model for evaluating the peripheral analgesic effect of plant extracts and drugs (Yimer et al, 2020).…”

Anti-urolithiatic, antibacterial, anti-inflammatory and analgesic effects of Erica arborea flowers and leaves hydromethanolic extracts: An ethnopharmacological study

“…The abdominal contractions result from the administration of subcutaneous acetic acid-induced peripheral analgesic activity ( Yimer et al, 2020 ). In addition, it is responsible for the high release of free pain-causing substances such as arachidonic acid by COX and prostaglandin pathways, which produce sensitization of primary afferent nociceptors, thus making the visceral pain inside the treated peritoneal fluids via increasing blood flow ( Fyad et al, 2020 ).…”
