Black pepper (Piper nigrum) is

Black pepper (Piper nigrum) is more than a culinary spice—it is a pharmacological bioavailability enhancer. Its active compound, piperine, modulates drug-metabolizing enzymes and transport pathways, increasing systemic absorption of co-administered compounds such as curcumin. Long recognized in traditional formulations and now supported by pharmacokinetic research, pepper illustrates a core principle of therapeutics: efficacy depends not only on potency, but on delivery dynamics.
