Quality Aspects of Herbal Drugs and its Formulations

Abstract

Growing interest in complementary medicine and natural therapies has led to a sharp increase in the demand for herbal medications worldwide. Because plant sources vary widely, phytochemical compositions are complicated, and manufacturing processes are inconsistent, quality assurance in herbal medication formulations remains a significant difficulty despite their widespread use. Maintaining the quality of herbal medications is crucial for both patient safety and therapeutic efficacy, mainly because certain products have been found to include contaminants and adulterants. This review thoroughly examines herbal medications' quality elements, addressing important factors like stability, standardization, authentication, and origin. We discuss contemporary approaches, such as macroscopic, microscopic, and chromatographic techniques, for evaluating the authenticity and purity of raw materials. To guarantee consistency in bioactive content a crucial component of repeatable therapeutic effects the review goes into additional detail about standardization procedures. Additionally reviewed are quality control methods for identifying microbiological contaminants, pesticides, heavy metals, and adulterants. To further highlight the significance of shelf-life studies, the stability of herbal formulations influenced by variables such as formulation types and storage conditions is examined. New developments in analytical methods, such as DNA barcoding and mass spectrometry, are cited as crucial instruments for improving the quality control of herbal medications. This review seeks to offer a framework for raising regulatory requirements and guaranteeing the efficacy and safety of herbal formulations globally by addressing these crucial quality control issues.
