Lack of in vivo genotoxic effect of dried whole Aloe ferox juice

Aloe ferox Mill is widely used as a traditional herbal medicine for the treatment of a broad spectrum of illnesses given its laxative, anti-inflammatory, bitter tonic, anti-oxidant, antimicrobial and anti-cancer properties.Using the in vivo alkaline comet assay in animals (OECD 489), this study inve...
