Also known as "passion flower" or "grenadilla," passionflower ( Passiflora incarnata ) is a plant recognized by the European Medicines Agency for its sedative properties. It is traditionally used to soothe anxiety and nervousness and promote better sleep.
Passionflower, a climbing plant of South American origin
Passionflower is a perennial climbing plant of the Passifloraceae family, native to South America and now cultivated in many tropical and temperate regions. Discovered in the 16th century by Spanish missionaries in Peru, it owes its name to the Jesuits, who saw in the particular structure of its flower a symbolic representation of the Passion of Christ: the crown of thorns, nails and whip are evoked by the different floral parts.
Its nickname "grenadilla" comes from its fruit, which resembles a small pomegranate with a sweet and tangy flavor, sometimes used in cooking in juices, sorbets, or jams. Used since Aztec times for its soothing properties, passionflower was only introduced for medicinal use in Europe in the 19th century. Today, it is among the most widely used medicinal plants in Western herbal medicine.
What are the active compounds in passionflower?
Passionflower owes its properties to several families of compounds, including flavonoids with antioxidant properties. Research suggests that certain constituents of the plant may interact with GABA receptors, a neurotransmitter involved in regulating anxiety and relaxation in the nervous system. This helps explain the traditional use of passionflower as a calming herb.
The European Medicines Agency (EMA) recognizes the traditional use of the aerial parts of Passiflora incarnata for the relief of mild symptoms of mental stress and to promote sleep, which places passionflower among the best-documented plants in the European pharmacopoeia.

Other traditional uses of passionflower
Beyond its effects on sleep and anxiety, passionflower is also traditionally used as an antispasmodic, particularly to relieve certain muscle spasms and digestive problems of nervous origin. Some preliminary studies have also explored a possible effect on blood pressure, linked to its antioxidant content, but these avenues require further confirmation before any firm conclusions can be drawn.
How to consume passionflower?
Passionflower comes in several forms, to be chosen according to individual preferences and lifestyle.
Infusion remains the most traditional method: simply steep one teaspoon of passionflower powder (1 to 2 g) in 150 ml of simmering water for about ten minutes. It can be consumed one to four times a day, ideally half an hour before bedtime to help with falling asleep.
For added convenience, liquid extracts to be diluted in water or an infusion are also available, as well as tablets, capsules or gummies dosed with standardized passionflower extract, often combined with other sleep plants in the same formula.
Precautions for use
Passionflower is generally well tolerated at recommended doses. As a precaution, its use is not recommended for pregnant or breastfeeding women. It may potentially enhance the effects of certain sedatives or anxiolytics: individuals taking such medications should consult a doctor before combining it with other herbs. As with any herbal remedy, it is recommended to adhere to the stated doses and not exceed the recommended duration of use without professional advice.
