Passion fruit seeds may offer significant cardiovascular benefits

Sano, Sugiyama, Ito, Katano, and Ishihata (2011) investigated the vasorelaxing effects of the major polyphenols found in passion fruit seeds. Vasorelaxation refers to the widening of blood vessels resulting from relaxation of smooth muscle cells within the blood vessel walls. This widening of blood vessels leads to a decrease in vascular pressure which is important for a healthy cardiovascular system.
