Rating (out of 5): 2

Cayenne pepper (Capsicum annuum) has a long history of traditional use to support circulatory health, including the health of capillaries and blood vessels. Herbalists and traditional medicine systems, such as Ayurveda and Traditional Chinese Medicine, have used cayenne to "stimulate blood flow" and "strengthen the vascular system." The active compound in cayenne, capsaicin, is known for its warming and vasodilatory effects, which are believed to help improve circulation and possibly support capillary function.

However, while there is some preliminary scientific evidence that capsaicin can influence blood flow and may have a mild vasodilatory effect, there is limited direct clinical research specifically connecting cayenne pepper or capsaicin with improved capillary health or the prevention of capillary-related disorders in humans. Most available studies are either animal-based or focus on general cardiovascular benefits, such as reduced blood pressure or improved endothelial function, rather than specifically targeting capillaries.

In summary, the use of cayenne pepper to support capillary health is primarily justified by traditional use, with some suggestive but limited scientific evidence. The overall quality and quantity of scientific research specifically addressing capillary support is not strong enough to fully endorse its effectiveness based on modern evidence.
