Passionflower Whole Herb Extract
Also known as: Passionflower, Passion Vine, Passiflora incarnata
Overview
Passionflower (*Passiflora incarnata*) is a perennial vine native to North America, traditionally used for its medicinal properties. As an herbal supplement, it is primarily recognized for its calming and sedative effects, making it a popular choice for managing anxiety and insomnia. The active compounds in passionflower are believed to interact with the central nervous system, promoting relaxation without the harsh side effects associated with some pharmaceutical sedatives. It is available in various forms, including teas, capsules, and liquid extracts. While research shows promise, particularly in reducing anxiety levels and improving sleep quality, larger clinical trials are needed to fully validate its efficacy and establish consistent outcomes. Passionflower is generally considered safe when used appropriately, but it's important to be aware of potential side effects and interactions.
Benefits
Passionflower has shown potential in reducing anxiety levels, with some studies indicating it can be as effective as certain conventional medications in mild to moderate cases. Research suggests that passionflower can improve sleep quality, helping individuals fall asleep faster and experience more restful sleep. Some evidence suggests it may also be beneficial in treating symptoms of substance withdrawal, potentially alleviating anxiety and promoting relaxation during the withdrawal process. Studies indicate that passionflower may possess antitussive properties, potentially helping to relieve coughs. These benefits are primarily observed in individuals with anxiety disorders, insomnia, and those undergoing substance withdrawal. While some studies show significant reductions in anxiety, the effect sizes vary, and more research is needed to establish consistent outcomes.
How it works
Passionflower is believed to exert its anxiolytic and sedative effects by interacting with the GABA system in the brain. GABA is a neurotransmitter that inhibits nerve transmission in the brain, calming nervous activity. Compounds in passionflower, such as flavonoids, may bind to GABA receptors, enhancing GABA's effects and promoting relaxation. This interaction with the central nervous system helps to reduce anxiety and induce sleep. While the exact mechanisms are still being investigated, the modulation of GABAergic neurotransmission is considered a primary pathway through which passionflower exerts its therapeutic effects.
Side effects
Passionflower is generally considered safe when used appropriately, but it can cause side effects in some individuals. Common side effects include dizziness and drowsiness, which can impair the ability to drive or operate machinery. Less common side effects include gastrointestinal upset. Rare side effects may include allergic reactions. Passionflower may interact with sedatives and antidepressants, potentially enhancing their effects and increasing the risk of side effects. It is contraindicated during pregnancy and breastfeeding due to a lack of safety data. Caution is advised in children and individuals with liver or kidney issues. It is important to consult with a healthcare professional before using passionflower, especially if you have any underlying health conditions or are taking other medications.
Dosage
The typical dosage of passionflower extract ranges from 250 to 750 mg per day, depending on the intended use. For anxiety and sleep disorders, a dosage of 500-750 mg per day is often recommended. It is generally not recommended to exceed 1000 mg per day. Passionflower is often taken before bedtime to promote sleep or as needed for anxiety relief. Capsules and teas are common forms of passionflower supplements. The bioavailability of passionflower compounds may vary based on the preparation method. While there are no specifically identified required cofactors, it is always best to take supplements with food to improve absorption.

The review highlights the potential of passionflower as an anxiolytic but notes limitations due to small sample sizes and variability in study designs, suggesting a need for larger, more standardized trials to confirm these findings.
- https://pubmed.ncbi.nlm.nih.gov/33352740/ – This randomized controlled trial examined the effects of passionflower tea on sleep quality in 41 participants. The study found that passionflower tea improved sleep quality compared to a placebo, indicating its potential as a natural sleep aid. However, the small sample size limits the generalizability of the findings, and further research with larger cohorts is warranted.

The study revealed that passionflower reduced anxiety symptoms with fewer side effects than oxazepam, suggesting it could be a viable alternative for some patients. The lack of long-term follow-up and comparison to a single benzodiazepine limit the study's scope.
