Herbal bioenhancer is an agent of herbal origin or any phytomolecule which is capable of enhancing bioavailability and bio-efficacy of a particular drug or nutrient with which it is combined without any typical pharmacological activity of its own at the dose used. Maximizing bioavailability is therapeutically important because the extent of bioavailability directly influences plasma concentrations and consequently therapeutic efficacy. Bioavailability enhancement can make the expensive drugs affordable and reduce the toxic effects by reducing the required dose of drugs. A bioenhancer may act by different mechanisms like promoting the absorption of the drugs from gastrointestinal tract, inhibiting or reducing the rate of biotransformation of drugs in the liver or intestines, modifying the immune system in such a way that the overall requirement of the drug is reduced substantially, etc. Ayurveda the science of life is based on highly scientific principles.
