Background:
Heracleum persicum is a common dietary spice with several traditional medicinal properties important for cardiovascular health including antioxidant, hypolipidemic, and anti-inflammatory effects. This study explored the effects of supplementation with H. persicum fruit on the angiographic findings of patients with minimal coronary artery disease (CAD).
Methods:
Subjects who were diagnosed with <50% stenosis in any of their coronary arteries by angiography were selected for this trial and randomly assigned to H. persicum hydroalcoholic fruit extract (n = 15; 300 mg/day) or placebo (n = 12) for 6 months. At the end of the trial, participants underwent a second coronary angiography in order to evaluate the progression of their disease.
Results:
Posttrial angiography did not reveal any improvement in the number of stenosed vessels after consumption of H. persicum extract versus placebo (P > 0.05). Similarly, there was no significant difference between the study groups in terms of disease progression and chest pain score (P > 0.05).
Conclusions:
The present results do not support any clinically significant benefit of supplementation with H. persicum extract on the angiographic findings of in patients with minimal CAD.
