Inhibition of inducible nitric oxide synthesis by <i>Cimicifuga racemosa</i> (<i>Actaea racemosa</i>, black cohosh) extracts in LPS-stimulated RAW 264.7 macrophages

Abstract

Extracts from the roots of C. racemosa inhibit nitric oxide production by reducing iNOS expression without affecting activity of the enzyme. This might contribute to the anti-inflammatory activities of C. racemosa.
