Passionflower has one of the most stunning, intricate flowers in the world. The trailing vine is native to the southern United States—although the “passion” part of its name came from European explorers who saw symbols of the Passion of Christ in its showy, fringed blossoms.

Passionflower herb powder is ground from dried leaves and stems of the Passiflora incarnata vine. All parts of the plant are known to combat anxiety and promote relaxation, but the leaves are perhaps the most potent. Contemporary herbalists recommend it as a sleep aid and gentle sedative.

Cut and sifted passionflower herb is popular as a simple tisane or combined with other calming herbs, and the herb powder is often encapsulated as a supplement. Although generally considered safe, some people experience dizziness when using passionflower herb, and it should be used cautiously with other herbs or medications.
