Parts Used & Where Grown

Passion flower is a climbing vine renowned for its beautiful white flowers with purple, blue, or pink calyx crown blooms. The plant is native to North, Central, and South America. While primarily tropical, some of its 400 species can grow in colder climates. The mystery of such a beautiful blossom emerging from an unassuming bud has been compared to the Passion of Christ. This inspired the plant’s name, which dates back to the 17th century. The leaves, stems, and flowers are used for medicinal purposes.

Anxiety (Valerian)
100 to 200 mg valerian and 45 to 90 mg passion flower three times a day
A combination of passion flower and valerian has been shown to reduce symptoms in people suffering from anxiety.

Several plants, known as “nervines” (nerve tonics), are used in traditional herbal medicine for people with anxiety, with few reports of toxicity. Most nervines have not been rigorously investigated by scientific means to confirm their efficacy. However, one study found that a combination of the nervines valerian and reduced symptoms in people suffering from anxiety.

Insomnia
Refer to label instructions
Passion flower is commonly recommended by doctors as a mild sedative for those suffering from insomnia or nervous exhaustion.

Combining valerian root with other mildly sedating herbs is common both in Europe and the United States. Chamomile, hops, , lemon balm, American scullcap, and catnip are commonly recommended by doctors. These herbs can also be used alone as mild sedatives for those suffering from insomnia or nervous exhaustion. Chamomile is a particularly good choice for younger children whose insomnia may be related to gastrointestinal upset. Hops and lemon balm are approved by the German government for relieving sleep disturbances. In a double-blind trial, the combination of valerian root and hops was significantly more effective than valerian root alone for treating insomnia.

Traditional Use (May Not Be Supported by Scientific Studies)

The historical use of passion flower is not dissimilar to its current use as a mild sedative. Medicinal use of the herb did not begin until the late 19th century in the United States. Passion flower was used to treat nervous restlessness and gastrointestinal spasms. In short, the effects of passion flower were believed to be primarily on the nervous system, particularly for anxiety due to mental worry and overwork.1

The effectiveness of passion flower as a treatment for anxiety has been confirmed in a double-blind study. In that study, 45 drops per day of an extract of passion flower taken for four weeks was as effective as 30 mg per day of oxazepam (Serax®), a medication used for anxiety.2
