Exposure to any kind of noise exceeding 90 dB is reported to be a stressor. This study focuses on whether Emblica officinalis supplement (333 mg/kg/b.wt) could avert the noise stress induced behavioural changes in Wistar albino rats. Noise stress animals were exposed to 100 dB (4 hr/day) for 15 days. When compared to control and E. officinalis treated animals, noise stress animals showed an increased immobilization, rearing, fecal bolus and marked decrease in ambulation and grooming in open field test, whereas in elevated plus maze, it showed a marked decrease in the number of open arm entry and percentage, time spent in open arm and percentage. Noise stress animals treated with E. officinalis showed improvement in all the above observations and recovered from the stress. The results imply that E. officinalis possesses anti-stressor property by reducing the noise stress induced alterations in behaviour, its effect might be due to the antioxidant property of E. officinalis.
