Antiinflammatory activity and acute toxicity of Dodonaea viscosa.

The hydroalcoholic extract (HAE) of the leaves of Dodonaea viscosa, given by oral route at dose of 300 mg/kg, significantly inhibited the paw edema induced by carrageenin injection. The extract did not show any sign of toxicity in mice up to 5000 mg/kg p.o. This result seems to support the use of D. viscosa leaves ethanolic extract in relieving inflammation.
