Peimine is primarily used in traditional medicine for its anti-inflammatory and analgesic properties. It has been studied for its potential in treating respiratory conditions such as bronchitis and cough due to its expectorant effects. Research also indicates neuroprotective activity, suggesting possible applications in managing neurodegenerative disorders like Alzheimer's disease. Additionally, peimine exhibits antitumor potential by inducing apoptosis in certain cancer cell lines, making it a subject of interest in oncology research. Its sedative and anxiolytic effects are utilized in formulations aimed at improving sleep and reducing anxiety.
