Passion flower is a vine native to Asia, New Zealand, Australia and tropical regions of the U.S.
In addition to its value as a garden ornamental, passion flower is cultivated and harvested for its leaves, stems and flowers, which produce a lovely tea. Passion flower is often combined with other calming herbs in tea blends, including valerian, lemon balm and hops.
Safety: Passion flower is considered safe in therapeutic dosages, but should not be used during pregnancy or lactation.
