Osthole is widely studied for its pharmacological properties and is primarily used in research related to anti-inflammatory, anti-cancer, and neuroprotective applications. It has shown potential in inhibiting tumor growth in various cancer cell lines by inducing apoptosis and suppressing cell proliferation. In neurological research, osthole demonstrates protective effects in models of Alzheimer’s and Parkinson’s diseases due to its ability to cross the blood-brain barrier and reduce oxidative stress. It is also investigated for its role in bone health, where it may promote osteoblast differentiation and support bone formation. Additionally, osthole exhibits anti-allergic and anti-asthmatic effects by modulating immune responses and reducing histamine release. Its use remains largely experimental, focused on preclinical studies for drug development.
