Versatile Applications
Cardiovascular Protection
Microcirculation improvement:
Inhibits PAF-induced platelet aggregation (IC50=0.8 μM)
Clinical data: 120mg/day ×8 weeks → 35% ↑cerebral blood flow
Anti-atherosclerotic:
40% ↓endothelial ICAM-1 expression
30% ↓MMP-9 activity (plaque stabilization)
Neuroprotective Mechanisms
Clinical Trials: Alzheimer's patients show 2.5-point MMSE improvement (24 weeks)
Sensory Function Enhancement
25% ↑retinal blood flow (diabetic patients)
15dB hearing threshold improvement (age-related hearing loss)
