Abstract
This review provides a comprehensive synthesis of the ethnopharmacological uses, modern applications, phytochemistry, and pharmacological mechanisms of Hippophae rhamnoides L. (H. rhamnoides) It begins by detailing its foundational role in traditional medical systems within its native range, including Tibetan, Mongolian, and Chinese medicine, as well as its broader Eurasian ethnobotanical applications. The work then systematically outlines the plant's diverse modern utilizations in nutraceuticals, cosmeceuticals, pharmaceuticals, and environmental remediation. A thorough organ-specific analysis of its phytochemical architecture that identifies key bioactive constituents in berries, seeds and leaves links to demonstrated pharmacological effects, including hepatoprotective, anti-inflammatory, cardioprotective and neuroprotective activities. A critical discussion on the potential interference of Pan-Assay Interference Compounds (PAINS) is included to provide a necessary caveat for interpreting bioactivity data. Finally, the review identifies persistent challenges including phytochemical standardization and the translational gap between preclinical and clinical research, and proposes future research directions focused on rigorous clinical trials, mechanistic studies and sustainable exploitation within a circular bioeconomy framework.
