Peripheral neuropathy was induced in rats by administration of vincristine sulfate 50 gg kg i.p. for 10 consecutive days. The mechanical hyperalgesia cold allo-dynia paw heat hyperalgesia and cold tail hyperalgesia were assessed by performing the pinprick acetone hot plate and cold tail immersion tests respectively. Biochemically the tissue thio-barbituric acid reactive species TBARS super-oxide anion content markers of oxidative stress and total calcium levels were measured. Vincristine administration was associated with the development of mechanical hyperalgesia cold allodynia heat and cold hyperalgesia. Furthermore vincristine administration was also associated with an increase in oxidative stress and calcium levels. However administration of Ocimum sanctum 100 and 200 mg kg p.o. and its saponin rich fraction 100 and 200 mg kg p.o. for 14 days significantly attenuated vincristine-induced neuropathic pain along with decrease in oxidative stress and calcium levels. It may be concluded that Ocimum sanctum has ameliorative potential in attenuating chemotherapy induced-painful neuropathic state which may be attributed to decrease in oxidative stress and calcium levels. Furthermore saponin rich fraction of Ocimum sanctum may be responsible for its noted beneficial effect in neuropathic pain in rats. Introduction Neuropathic pain has been described as the most terrible of all tortures which a nerve wound may inflict 1 . Despite progress in the .
