Abstract Reabsorption of the nucleus pulposus (NP) in lumbar disc herniation (LDH) refers to the natural absorption or even complete disappearance of LDH. In order to better treat LDH, it is necessary to further study its mechanism and develop new therapeutic drugs. Clematidis Radix Et Rhizoma is a ranunculus family plant which has multiple biological activities, and Embinin is one of its bioactive ingredients. However, its effects on LDH were unclear. In this study, the role of Embinin was investigated in LDH rat models. LDH model was established by lumbar epidural insertion of tail disc. Our results showed that Embinin promoted lumbar disc neovascularization, induced apoptosis of NP cells in LDH rats, and promoted lumbar disc resorption. Furthermore, mechanistic study showed that Embinin activated the cAMP pathway in the rat models. In conclusion, Embinin has the potential to serve as a drug for the treatment of LDH.
