Abstract
Flavonoids are an important class of phytopharmaceuticals in plants. Naringin (naringenin-
7-O-rhamnoglucoside) is a flavanone glycoside isolated from folk herbal medicine Exocarpium Citri
grandis (called Huajuhong in Chinese). Massive experimental works have been performed on naringin
describing its phytochemical, pharmacokinetic, and bioactive properties. Naringin was found to possess
multiple pharmacological activities in relieving inflammation, diabetes, neurodegeneration, cardiovascular
disorders, and metabolic syndrome. Recently, it has been approved as a potential antitussive
and expectorant for clinical trials. However, the pharmacokinetic aspects of naringin and its therapeutic
potentials in respiratory diseases have not been comprehensively reviewed. The present review provides
highlights of naringin with respect to its absorption, distribution, metabolism, excretion and its
therapeutic effects on cough, phlegm, and pulmonary inflammation. This review would be helpful for
the interpretation of pharmacokinetics and pharmacodynamics of naringin in clinical trials.
Keywords:
Naringin, pharmacokinetics, therapeutic efficacies, antitussive, expectorant, anti-inflammation.
