Rating (out of 5): 1

Bilberry (Vaccinium myrtillus) has a long history of use in traditional European herbal medicine for various circulatory and vascular conditions, including those related to arteriosclerosis (hardening and narrowing of the arteries). Traditionally, bilberry fruit and leaf extracts have been used to support blood vessel health, improve circulation, and reduce capillary fragility. This use is largely attributed to the high content of anthocyanins—potent antioxidant compounds thought to support vascular integrity and combat oxidative stress, which is implicated in the development of arteriosclerosis.

However, scientific validation for bilberry’s effectiveness specifically in treating or preventing arteriosclerosis is limited. Most modern research on bilberry focuses on its antioxidant effects, potential to improve microcirculation, and benefits for eye health (such as in diabetic retinopathy). While animal and in vitro studies suggest that bilberry anthocyanins may have favorable effects on lipid profiles and endothelial function (both relevant to arteriosclerosis), robust clinical trials in humans are lacking. Thus, while bilberry is traditionally used for vascular health and there is some mechanistic plausibility, the direct evidence for its efficacy in arteriosclerosis remains weak.

In summary, bilberry’s use for arteriosclerosis is primarily rooted in traditional herbal practice, with only preliminary scientific support and no high-quality clinical evidence to strongly endorse its use for this specific condition.
