Herbs from the Gentianaceae family are widely known for their medicinal and pharmacological properties. They were used centuries ago as a part of traditional medicine in China and Tibet. This review aims to draw attention to the potential uses of gentian herbs in treating various diseases, including skin conditions, gastrointestinal and liver disorders, wound healing, rheumatoid arthritis, and diabetes. The aim of our study was to systematically summarize current knowledge about key bioactive compounds present in both roots and aerial parts—such as xanthones, iridoids, and flavonoids—and highlight their pharmacological significance. We also focused on the Gentianaceae family’s usage in complementary and alternative medicine, as well as their anti-inflammatory, anti-melanogenic, anti-ischemic, anti-fibrotic, and antioxidant properties, which can be utilized in the treatment and prevention of dermatological diseases, such as skin cancers. Here, we involve ethnomedicinal knowledge with modern pharmacological data; we also highlight the scientific relevance of gentian-derived compounds in drug development. This review concludes that these species represent a promising source of natural agents, while also underlining the need for further research and conservation strategies to preserve threatened species.

Patients undergoing cardiac surgery are particularly vulnerable to infectious diseases, which may adversely affect perioperative outcomes and long-term prognosis both before and after the procedure. Moreover, those requiring heart transplantation must take immunosuppressive medications, further compromising their immunity. This narrative review aims to look for the sources of increased risk for infections as well as synthesize vaccination recommendations for these patient groups based on the available literature and guidelines. We considered the influence of age, comorbidities, length of hospitalization, procedure-related risks, and blood product transfusions on the increased risk of vaccine-preventable diseases. By comprehensively addressing these factors, healthcare providers can develop tailored vaccination strategies that maximize protection for cardiac surgical patients while minimizing potential complications and optimizing overall health outcomes.
