Effect of Passiflora Edulis Sims onReserpine Induced Fibromyalgia

Abstract

This study was carried out to assess the possible effect of Passiflora edulis Sims on reserpine-induced fibromyalgia with using different animal models and commonly used in the Virginia, southern Illinois, southeast Kansas and India as a folk medicine. Possible effect of extract of the plant was evaluated on reserpine-induced fibromyalgia. For evaluating the effect of this Plant leaves extract, different models were used such as tail flick, radiant heat, hot plate and inclined plane model. Evaluation of anti-depression activity, forced swim test and elevated plus maze (EPM) model were used. Investigations were shown that reserpine-treated animals responded with significantly increased sensitivity of pain in tail flick latency, decreased threshold of paw-withdrawal and immobility time and in Randall test. Whereas Plant leaves extract at different level of doses (e.g. 200 and 400 mg/kg) has shown a significant reduction in time of immobility, withdrawal latency of tail and the significant increase in mechanical and thermal hyperalgesia. The Passiflora edulis Sims showed inhibition of algesic condition in all the models which was dose dependent. During forced swim test extract of plant showed the significant reduce immobility time as compared with the control group, also in the plus‐maze method, Plant leaves extract showed increased time spend in open arm. The results were confirmed that the use of the extract of leaves of Passiflora edulis Sims in the traditional management of pain and enhances behavioural activity.
