Baicalein (BN) is an active ingredient naturally present in Chinese herbs, such as Scutellaria baicalein, Coptis chinensis, and Dendrobium officinale. It has a variety of pharmacological activities, including antioxidant, anti-inflammatory and antibacterial effects. Therefore, Baicalein (BN) is widely used in the field of medicine and is considered a potential natural medicine. Osteoporosis (OP) is a bone metabolic disease characterized by decreased bone mineral density and bone structure destruction, which is mainly caused by decreased bone formation and increased bone resorption. With the continuous development of molecular biology, the signaling pathways and gene targets of bone metabolism are also expanding. Recent studies have shown that baicalein may affect the function of osteoblasts, osteoclasts, and bone marrow mesenchymal stem cells through MAPK/ERK and MAPKs/NF-κB signaling pathways, so as to have a therapeutic effect on OP. However, the specific mechanism of baicalein in the treatment of OP is still unclear. This article reviews the literature, analyzes and summarizes the mechanism of action of baicalein, and discusses its potential in the prevention and treatment of OP, so as to provide a basis for the clinical application of baicalein.
