Our previous studies have shown that the ethanolic extract of Ocimum sanctum (OS) leaves was effective in alleviating the noise stress induced changes. Hence in this study, we have investigated the effectiveness of different types of crude OS extracts on some of the stress parameters after noise stress. The results of this study has shown that the active principle responsible for antistressor effect of ethanolic extract is also present in cold homogenised leaf extract of OS also. Hot extracts slightly decrease the potency of the active principle in normalizing corticosteroid level.Copyright 2002 John Wiley & Sons, Ltd.
