α-terpineol reduces mechanical hypernociception and inflammatory response.

α-Terpineol (TPN), a volatile monoterpene alcohol, is relatively non-toxic and one of the major components of the essential oils of various plant species. In this study, we tested for the antihypernociceptive activity of TPN (25, 50 or 100 mg/kg, i.p.

Citronellol, a monoterpene alcohol, reduces nociceptive and inflammatory activities in rodents.

We describe the antinociceptive and anti-inflammatory properties of citronellol (CT) in rodents. CT, a monoterpene alcohol, is a naturally occurring monoterpene compound prevalent in essential oils of various aromatic plant species, such as Cymbopogon citratus. In mice, when evaluated against acetic-acid-induced abdominal writhing, CT (25, 50 and 100 mg/kg, i.

Carvacrol attenuates mechanical hypernociception and inflammatory response.

Carvacrol is a phenolic monoterpene present in the essential oil of the family Lamiaceae, as in the genera Origanum and Thymus. We previously reported that carvacrol is effective as an analgesic compound in various nociceptive models, probably by inhibition of peripheral mediators that could be related with its strong antioxidant effect observed in vitro. In this study, the anti-hypernociceptive activity of carvacrol was tested in mice through models of mechanical hypernociception induced by carrageenan, and the involvement of important mediators of its signaling cascade, as tumor necrosis factor-alpha (TNF-α), prostaglandin E(2) (PGE(2)), and dopamine, were assessed.
