Veratrum species (Melanthiaceae) have a long history of medical usage throughout Europe, Asia, and North America. However, they are well-known for their toxicity. Their pharmacological significance stems from a number of steroidal alkaloids with unique C-nor-D-homosteroidal and isosteroidal structures. This review provides an overview of the Veratrum-derived steroidal alkaloids. It focuses on their structural diversity, manufacturing processes, isolation methods, biological activity, and potential as new therapeutic leads. Nearly 185 steroidal alkaloids have been found in Veratrum species. They are usually classified as cevanine, veratramine, jervine, verazine, and solanidine. Improvements in chromatographic and spectroscopic technologies, particularly HPLC-MS/MS and multidimensional NMR, allow for a more detailed understanding of the structures of these complex substances and ensure quality control. Biosynthetic studies suggest that cholesterol is an important starting point for their synthesis, but various late-stage enzymatic processes remain unknown. Veratrum alkaloids have a diverse biological activity. Notably, they inhibit the Hedgehog/SMO pathway, as seen in cyclopamine and its derivatives, and impact voltage-gated sodium channels, such as veratridine. This emphasizes both their medicinal potential and hazardous hazards. Semi-synthetic alterations and research into the link between structure and activity have resulted in derivatives with increased potency, stability, and solubility, including prominent cyclopamine analogs such as patidegib. In conclusion, this review identifies Veratrum steroidal alkaloids as essential natural structures that link traditional medicine and modern drug research. It also emphasizes the importance of carefully evaluating their toxicity, as well as further research into their production and pharmacological properties, in order to realize their full therapeutic value.
