(±)-N-3-Benzylnirvanol is a racemic mixture of (+)-N-3-Benzylnirvanol and (-)-N-3-Benzylnirvanol. Both enantiomers are selective inhibitors of cytochrome P450, specifically inhibiting CYP2C19.

Rhodionin and rhodionin can inhibit cytochrome P450 2D6 non-competitively with high specificity which could have implications for interactions with co-administered drugs; they can significantly suppress the elevation of the postprandial blood triglyceride level suggests that they may be to the treatment of lifestyle-related diseases such as hyperlipidemia and exogeneous obesity and to health foods.
