Passiflora incarnata extracts can be potentially used to produce organic sunscreens with a protective defense against UV radiations. The use of these plant compounds would diminish the concentration of synthetic UV filters in sunscreens.
P. incarnata is still used by Native Americans, for example Cherokees use the root of the plant as topical anti-inflammatory medicine. Tea made from the roots is used as a tonic for the liver and for skin boils.
