Black chokeberry (Aronia melanocarpa) has been investigated in some scientific studies for its potential cardiovascular benefits, including effects relevant to arteriosclerosis (the thickening and hardening of arterial walls). The berries are rich in polyphenols and anthocyanins, compounds known for their antioxidant and anti-inflammatory properties. Several small-scale human and animal studies suggest that chokeberry extracts may help reduce risk factors associated with arteriosclerosis, such as high blood pressure, LDL cholesterol, and oxidative stress. For instance, a double-blind, placebo-controlled trial published in Phytotherapy Research (2007) found that patients with metabolic syndrome who consumed chokeberry extract for two months showed significant reductions in total cholesterol, LDL cholesterol, and blood pressure compared to placebo. Other laboratory studies indicate chokeberry polyphenols may inhibit processes involved in the development of atherosclerotic plaques, such as LDL oxidation and endothelial dysfunction. However, the number of high-quality clinical trials remains limited, sample sizes are small, and long-term effects are not well established. As such, while there is some scientific basis for the use of black chokeberry in supporting cardiovascular health and potentially slowing arteriosclerosis progression, the evidence is still preliminary and not robust enough to warrant strong recommendations. More large-scale, rigorous clinical studies are needed to confirm these effects.
