Advanced Pharmacognostic Evaluation and Pharmaceutics-Based Standardization of Herbal Medicines for Improved Clinical Therapeutic Outcomes

Abstract

Since ancient times, herbal remedies have played an important role in the healthcare systems of many cultures and in many areas around the world. However, as public awareness of the potential dangers associated with synthetic medications (such as side effects), as well as the rising issue of antimicrobial resistance, and the increasing prevalence of chronic diseases has increased; the acceptance and use of herbal remedies continues to expand. While herbal remedies have tremendous therapeutic potential, many limitations such as, phytochemical variability, contamination, adulterated, improper processing, and a lack of standardization, can limit the therapeutic effectiveness of herbal remedies/products. These limitations lead to inconsistency in the quality, safety, and clinical outcomes of herbal remedies/products. Therefore, robust pharmacognostic evaluation and pharmaceutically-based standardization are critical for establishing the authenticity, purity, efficacy, and reproducibility of herbal medicine. Pharmacognostic processes include the macroscopic, microscopic, physicochemical, phytochemical, chromatographic, and molecular analysis of plant materials in order to identify and authenticate the source of a given herbal remedy/product, and to identify any contaminants/adulterants that may be present. Pharmaceutically-based standardization includes development of optimum extraction methods; the development of formulations; stability and bioavailability testing; and the development of methods for controlled distribution of the herbal remedy/product. The use of modern analytical technologies such as high-performance liquid chromatography (HPLC), gas chromatography-mass spectrometry (GC-MS), DNA barcoding, metabolomics, and nanotechnology have greatly enhanced the ability to accurately assess the quality of herbal medicine and to develop pharmacologically appropriate formulations. The therapeutic effect obtained by standardized herbal medicine (EHBM) has been found to significantly enhance therapeutic outcomes when used in the treatment of diabetes, cardiovascular diseases, cancer, inflammatory diseases, neurological diseases, and infectious disease, thus contributing to the establishment of EHBM within evidence-based healthcare systems.
