This study is intended to study the effects of one-time acute dosing of a solid extract of Passiflora incarnata, also known as Passionflower, on blood pressure and heart rate in students. Our hypothesis is that blood pressure levels and heart rates will decrease significantly in response to Passiflora incarnata.
