Mental health disorders, particularly anxiety and insomnia, are increasingly prevalent worldwide, prompting interest in herbal-based complementary therapies. This study surveyed 168 Hungarian healthcare professionals to evaluate their knowledge and recommendations regarding herbal sedatives and analyzed seven commonly suggested OTC products available in Hungary, using thin-layer chromatography (TLC) and UV–Vis spectrophotometry according to the European Pharmacopoeia. The survey revealed that 86.9% of respondents recommend herbal products for nervous system complaints, with Valeriana officinalis and Melissa officinalis being the preferred ingredients. Herbal teas and traditional herbal medicines were the most frequently suggested product categories. Laboratory analysis confirmed the presence of marker compounds in all tested products; however, significant variability in active ingredient concentrations was observed. One homeopathic product contained an unidentified alkaloid-like compound, raising safety concerns. Essential oil yields from tea mixtures also varied markedly, and some products did not meet pharmacopoeial standards for hypericin content. These findings highlight the popularity of phytotherapy among healthcare professionals and the need for stricter quality control of OTC herbal sedatives. Future research should include multi-batch analyses and clinical trials to establish robust evidence for efficacy and safety.
