Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Bilberry (Vaccinium myrtillus) has a long history of traditional use in European herbal medicine, particularly for circulatory and vascular health. Traditionally, bilberry has been used to “strengthen” the heart and improve blood circulation, especially in cases of “heart weakness” or mild cardiovascular complaints. This usage is rooted in folk medicine and herbal texts from the 19th and early 20th centuries, where bilberry was sometimes included in tonics aimed at supporting the heart and blood vessels.

The rationale for its use is mainly attributed to its rich content of anthocyanins and flavonoids, which are believed to promote capillary strength and improve microcirculation. Some animal studies and laboratory research suggest that anthocyanins may have antioxidant and vasoprotective effects, which could theoretically benefit cardiovascular health. However, direct clinical evidence supporting bilberry’s efficacy specifically for “heart weakness” or as a primary treatment for heart conditions is lacking. Most modern research on bilberry focuses on its role in eye health, diabetes, or peripheral circulation, rather than on direct effects on cardiac function.

In summary, while bilberry’s use for “heart weakness” is backed by traditional practices, there is limited scientific validation for this specific indication. Its reputation in supporting heart health is largely historical and based on general circulatory support, not robust clinical trials targeting heart disease or cardiac insufficiency. Therefore, its evidence rating for this use remains modest.
