Peiminine is widely used in traditional medicine for its anti-inflammatory and analgesic properties. It is commonly applied in formulations aimed at relieving respiratory conditions such as cough and bronchitis due to its expectorant effects. The compound also shows potential in modulating immune responses, making it useful in supporting treatments for chronic inflammatory diseases. In recent research, peiminine has drawn attention for its anti-cancer activity, particularly in inhibiting the growth of certain tumor cells, suggesting possible integration into adjunct cancer therapies. Additionally, it is studied for its neuroprotective effects, which may contribute to the development of treatments for neurodegenerative disorders.
