A Review on Challenges and Opportunities in Herbal Medicine

Herbal medicines and their formulations have been used for thousands of years across both developing and developed nations. These remedies represent therapeutic knowledge accumulated over generations through traditional medical systems and practices. In recent years, herbal treatments have gained increasing acceptance worldwide due to their perceived effectiveness, safety profile, and minimal adverse effects. India possesses an extensive and valuable history of traditional herbal practices, especially through its indigenous medical systems such as Ayurveda, Siddha, and Unani, which primarily rely on herbal and herbo-mineral preparations. These formulations may include a single plant or a combination of multiple herbs, which makes standardization and quality control more challenging compared to conventional pharmaceutical drugs. Furthermore, the available scientific evidence regarding the safety and efficacy of many traditional medicines is still inadequate to meet global regulatory requirements. This review aims to highlight the major barriers and concerns related to conservation of medicinal plants, advancements in research and technology, production and quality control, safety and clinical validation of herbal products, as well as the emerging opportunities for herbal medicine at both national and international levels.
