Rehmannioside D is an indicator component of Dihuang (Rehmanniae Radix), a traditional Chinese medicine that shares the same origin in both medicine and food. Rehmannioside D, a natural iridoid glycoside, exhibits a broad spectrum of pharmacological activities, including nourishing yin and blood, cooling blood and stopping bleeding, providing analgesia, acting as an antidepressant, and preventing osteoporosis, thereby meriting intensified investigation. This paper systematically reviews the recent advances in rehmannioside D research, detailing the optimization of determination methods and the application of new technologies for rehmannioside D, as well as the content determination in different dosage forms. The principles of content variation in different producing areas, processing methods, and tissues of Rehmanniae Radix are summarized. Furthermore, it focuses on elucidating the pharmacological effects of rehmannioside D in the endocrine and cardiovascular systems, nervous system, and other aspects. In addition, this paper critically discusses the existing challenges in its research. The aim is to provide a scientific basis for the further development and clinical application of rehmannioside D, as well as the quality identification and comprehensive utilization of Rehmanniae Radix.
