Safety, efficacy and anti-inflammatory activity of rho iso-alpha-acids from hops

Rho iso-alpha-acids (RIAA) is a modified extract from the flower cone of hops (Humulus lupulus L.). The safety profile and anti-inflammatory activity of RIAA was assessed using in vitro models and clinical biomarkers. This study suggests that RIAA is an alternative to NSAIDs with an expected reduction in adverse events.
