What is Passionflower?
Passionflower is a herb native to the tropical areas of the United States, it typically grows in the southeast region of the US where the weather is hot.
The scientific name for passionflower is Passiflora incarnata. Other common names include maypop, purple passion flower, apricot vine, and old field apricot.
Passionflower is primarily used as a sleep aid and to reduce anxiety. Additional research shows that it can help manage menopause symptoms, regulate blood pressure, calm muscle spasms, increase memory, manage attention-deficit hyperactivity disorder (ADHD), and has anticonvulsant effects.
We will dive into some of these benefits below.
Health Benefits of Passionflower:
Passiflora incarnata has many purported health benefits. We’ve listed the top research-backed benefits below, based on our analysis.
1. May Improve Sleep Quality
Studies have shown that about one-third of the world’s population suffers from differing levels of insomnia. Lack of sleep can significantly impact one’s overall health and well-being and lead to negative health conditions. With the rise of herbal medicine, passionflower is popularly used as a sleep aid.
A double-blind, placebo-controlled study demonstrated that consuming one cup of passionflower tea nightly has short-term sleep benefits. These sleep benefits include better sleep quality and a feeling of refreshment upon waking.
Another clinical trial studied the effects of passionflower on individuals with insomnia. Findings revealed that a small dose of 60mg (extract form) could significantly increase total sleep time. It appears that passionflower improves sleep efficiency while decreasing the likelihood of waking up during the night.
Summary:
Passionflower appears to be a promising natural remedy for improving sleep quality. However, longterm human clinical trials are needed to ensure its efficacy for insomnia.
2. May Reduce Anxiety
Anxiety is the body’s natural response to stress. While it’s natural, there may be a concern when anxiety is persistently occurring, and the feelings of fear, worry, nervousness, or irritability impede one’s everyday life.
General Anxiety Disorder (GAD) is the most common type of anxiety. GAD is characterized as excessive anxiety or extreme nervousness that interferes with daily functioning. While there are many pharmaceutical treatments for anxiety, many of them are overused and have side effects. Researchers are looking at passionflower as a safer alternative.
A clinical trial compared passionflower and oxazepam (a benzodiazepine used to treat anxiety) in the treatment of GAD. The study revealed that passionflower extract (45 drops/day) and oxazepam (30mg/day) are both effective in the management of GAD with no significant difference in efficacy. However, passionflower showed an advantage with a lower incidence of impairment on job performance as compared to oxazepam.
Many patients experience stress or anxiety before surgical procedures. A clinical trial showed that patients given an oral dose of 500mg of passionflower ninety minutes before surgery had significantly decreased anxiety levels, indicating that passionflower may be a useful herb for stress.
Another study that examined anxiety during dental procedures used 20 drops of passionflower extract the night before surgery and 20 drops the morning of surgery (ninety minutes prior). The results showed a decrease in overall anxiety levels.
Another clinical trial studied the anxiolytic (anti-anxiety) effects of passionflower and midazolam (a benzodiazepine used to treat anxiety) on patients undergoing dental extraction. It showed an anxiolytic effect similar to midazolam, with fewer adverse events noted.
Summary:
Due to it’s relaxing effect, passion flower appears to be an effective herb for reducing GAD (generalized anxiety disorder). It also appears to be a safer alternative to the standard pharmaceutical approach.
3. May Reduce Menopausal Symptoms
Research has looked at the potential benefit of using passionflower as an herb for for reducing menopausal symptoms.
As women age and estrogen production drops, menopausal symptoms typically arise. Common symptoms include hot flashes, vaginal dryness, sleep disturbances, anxiety, and depression. It’s thought that the menopause transition is experienced by 1.5 million women each year.
A randomized clinical trial compared the effects of St. John’s wort and passionflower on women with menopausal symptoms. Findings revealed that there were no significant differences between these two herbs, as they both resulted in decreased menopausal symptoms, including vasomotor signs (heart palpitations, hot flashes, etc.), insomnia, depression, anger, and headaches.
Additionally, the other benefits listed in this article, namely sleep support and anxiety reduction are also extremely helpful during the menopause transition.
Summary:
Initial research shows that passionflower may be benfical for women encountering menopausal sympoms. Further research is needed to verify the efficacy.
4. May Support Cognitive Health
Research shows a vital connection between insomnia and neurodegenerative diseases, implying that chronic insomnia may progress to Alzheimer’s disease.
One animal study found that passion flower extract helped to improve neurogenesis. Neurogenesis is the process of new neurons forming in the brain. This study may suggest that passionflower can be a potential treatment for enhancing memory and preventing Alzheimer’s disease through its actions on the hippocampus (the memory center of the brain).
A recently published meta-analysis noted that Passiflora incarnata may be helpful in treating symptoms in neuropsychiatric patients. The researchers also noted that no adverse effects, including memory loss or collapse of psychometric functions, were observed in any of the trials that they reviewed.
Summary:
Animal studies show that passionflower has the ability to improve neurogenesis. While this research is promising, human clinical trials are needed to confirm these findings.
