Anti - inflammatory and sedative - hypnotic activity of the methanolic extract of the leaves of mentha arvensis.

Mentha arvensis Linn, a plant used as traditional medicine and in perfumery, has now been explored for its pharmacological activities as an anti-inflammatory and also as sedativehypnotic plant drug. The methanolic extract of the leaves after being processed, was taken for the pharmacological study. Anti-inflammatory activity was carried out on albino rats. Further, the activity was compared to that of a standard anti-inflammatory drug - nimesulide and the percent inhibition of oedema determined. The sedative hypnotic activity, when carried out on mice, showed the potentiation of pentobarbitone induced sleeping time. The data of average recovery time was analyzed to show the standard deviation from the mean.
