Peripheral nerve injury (PNI) is one of the major health concerns faced by the community at present. Till now, available therapeutic approaches are ineffective to fully heal a nerve injury and to assure the functional recovery entirely. Natural compounds can prove attractive and effective drug candidates to bridge up this gap. In this scenario, the present study was designed to explore the role of methanolic extract of Foeniculum vulgare (F. vulgare) seeds in accelerating the function regain following a sciatic nerve injury in a mouse model. For this purpose, 12 adult healthy albino mice (BALB/C), 8-10 weeks old, were grouped as control (Ctrl, n = 6) and treatment (Trt, n = 6). The treated group was given methanolic extract of F. vulgare (200 mg/kg per day) started from the day of nerve crush until the end of the study. The sensorimotor function regain assessed by hot plate test, grip strength, and SFI assessments was found significantly (p < .05) ameliorated in the F. vulgare-treated group. A prominent improvement in the muscle mass of the treated group further affirmed these effects. Furthermore, morphometric analysis of muscle fiber cross-sectional area of tibialis anterior muscle between groups revealed a noticeable improvement in muscle fibers' diameter of the treated group. Conclusively, these findings suggest that F. vulgare methanolic extract exhibits the potential to escalate functional recovery following a peripheral nerve injury. However, the real players of this extract and the mechanism involved in boosting functional restoration need to be dissected by further work.
