Extracts prepared using crude solvents exhibited higher antifungal activity as compared to their corresponding aqueous extracts. No good activity was observed in the aqueous extract. The pathogen inhibiting activity was found to be dose dependent.

Silymarin (100 mg/kg), a known hepato-protective drug used for comparison exhibited significant activity.
