Imperialine 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 asthma due to its ability to relax smooth muscle tissue and reduce airway inflammation. Research also suggests that imperialine exhibits antitumor activity by inducing apoptosis in certain cancer cell lines, making it a subject of interest in oncology-related studies. Additionally, it has been explored for its antiviral effects, particularly against some strains of respiratory viruses. Its bioactive nature supports its role in herbal formulations aimed at boosting immune response and managing chronic inflammatory diseases.
