The flavonoids in passion flower are the primary constituents responsible
for its relaxing and anti-anxiety effects. European pharmacopoeias
typically recommend passion flower products containing no less than
0.8% total flavonoids. The European literature involving passion
flower recommends it primarily for anti-anxiety treatment; in this
context, it is often combined with valerian, lemon balm, and other
herbs with sedative properties.
