Mother root of Aconitum carmichaelii Debeaux exerts antinociceptive effect in Complet Freund’s Adjuvant-induced mice: roles of dynorpin/kappa-opioid system and transient receptor potential vanilloid type-1 ion channel

摘要

BackgroundProcessed Chuanwu (PCW), the mother root of Aconitum carmichaeliiDebeauxv, has been widely used as a classic Traditional Chinese Medicine for pain relieve for over two millennia clinically. However, its action on chronic inflammatory pain has not been clarified. Here, we investigated the antinociceptive effect of PCW in complete freund’s adjuvant (CFA)-induced mice and its possible mechanisms associated with opioid system and TRPV1 ion channel.
