Abstract Natural products (NPs) including herbal teas are widely consumed in Malaysia but lack stringent regulation. Naturally occurring phytochemicals including estragole (genotoxic), aristolochic acids (AAs; Group 1 carcinogen) and certain pyrrolizidine alkaloids (PAs; Group 2B carcinogen) pose severe hepatotoxic and nephrotoxic risk. An integrated risk assessment using the Margin of Exposure (MOE) and the RISK21 framework was applied to 90 NPs (30 per compound).
