The aqueous extracts obtained from three Helichrysum species (Asteraceae) growing in Turkey, H. arenarium (L.) Moench. subsp. aucheri (Boiss.) Davis & Kupicha, H. noeanum Boiss. and H. pilicatum DC. subsp. pilicatum, were evaluated for their in vivo anti-inflammatory activity using carrageenan-induced hind paw edema and antinociceptive activity using p-benzoquinone-induced abdominal constriction test. Aqueous extracts from H. arenarium and H. pilicatum subsp. pilicatum showed 37.0 %, 30.4 % inhibition at 100 mg/kg doses and 31.2%, 28.3% at 200 mg/kg doses in p-benzoquinone-induced abdominal constriction test, respectively, without inducing any gastric damage. The aqueous extracts of all the plants didn't show any anti-inflammatory activity in carrageenan-induced hind paw edema model at 50, 100 and 200 mg/kg doses. During the acute toxicity evaluation, neither death nor gastric bleeding was observed for any of the plant extracts.
