Dried root tubers of L.aggregata have been widely used in Chinese herbal medicine for thousands of years to promote qi, relieve pain, warm kidney, and disperse cold. This review aims to assess the research progress of L.aggregata, to comprehensively understand its development status, to point out the shortcomings of the existing researches, and to provide reference for further research on L.aggregata. By searching various databases for literatures on "Lindera aggregata", "Linderae Radix" and "Lindera strychnifolia", as well as relevant textbooks and digital documents, an overall and critical review of the subject was conducted. Through phytochemical studies on different parts of L.aggregata, about 260 compounds were isolated, including flavonoids, alkaloids, terpenes, volatile oils, and other compounds. A large number of in vivo and in vitro studies have shown that L.aggregata has a plethora of pharmacological effects such as anti-cancer, anti-arthritis, anti-bacterial, anti-oxidation, anti-diabetic nephropathy, hepatoprotective, lipid-lowering effect and so on. While the pharmacological effects of L.aggregata have been confirmed, most studies only use simple in vitro cell lines or animal disease models to evaluate their pharmacological activities. Therefore, future research should be conducted in a more comprehensive clinical manner. Further pharmacological research is also necessary to fully clarify the action mechanism of L.aggregata. It is also interesting to note that L.aggregata is often used to treat frequent urination in ancient times, but its molecular basis and mechanism of action are still unclear, and systematic studies are lacking. In terms of quality control, the source of L.aggregata is single, mostly wild, and the main medicinal part of L.aggregata is the tuber, while the yield of straight root is large. Therefore, further attention should be paid to the rapid propagation technology of L.aggregata and whether straight root can be included in medicinal use. It is also worth thinking whether sulfur-fumigation is necessary for preserving L.aggregata. As vinegar-processing is a common processing method for L. aggregata, the mechanism of such processing method remains to be investigated. In addition, in-depth research on the pharmacokinetics and long-term toxicity of L.aggregata is necessary to ensure its efficacy and safety. Copyright © 2023 Elsevier B.V. All rights reserved.
