Passion Flower
© Steven FosterHow It Works
For many years, plant researchers believed that a group of harman alkaloids were the active constituents in passion flower. Recent studies, however, have pointed to the flavonoids in passion flower as the primary constituents responsible for its relaxing and anti-anxiety effects.3 European herbal pharmacopoeias typically recommend passion flower products containing no less than 0.8% total flavonoids. The European literature involving passion flower recommends it primarily for the treatment of mild to moderate anxiety. In this context, it is often combined with valerian, lemon balm, and other herbs with sedative properties.
How to Use It
The recommended intake of the dried herb is 4–8 grams per day.4 To make a tea, 0.5 to 2.5 grams of the herb can be steeped with boiling water for ten to fifteen minutes and drunk two to three times per day. Alternatively, 5–10 ml of passion flower tincture can be taken three to four times per day.
