Passion flower is the common name for the passiflora incarnata plant that grows on a vine. This plant is a beautiful flower that is known for its sedative and calming effects. It helps to quiet the mind and bring one back into the present by relaxing the central nervous system. This can make it helpful for anxiety, nervousness and having trouble sleeping.
The Passion flower is part of the passifloraceae species. These flowers grow on a vine and are sometimes referred to as passion vines. This family contains hundreds of different plants. Passiflora Caerulea is the blue passion flower and it may have some medicinal properties, but it is the P. incarnata subtype of the species from the passion vine that is most often used in medicine. The Blue Passionflower is native to South America while the passiflora Incarnata is found in North America and can survive in colder weather.

The flower of the P.incarnata species is different from most flowers that you will come across. It can look like it is from another world. It grows on a vine and has five petals that are a bluish-purple-white. In the centre of the petals is a group of appendages growing off the flower called a corona.

Where the name comes from?

They used the name passion for the passion of Christ believing the plant was intricately linked to their experience. Different areas will refer to the plant with a slightly different, but this underlying religious motive is present in whatever people refer to this plant as.
Does Passionflower produce fruits? Can you eat them?
Depending on the species of passiflora different fruit are produced. Passiflora Incarnata can produce a specific fruit that is often referred to as a maypop. May pop fruit can be eaten when they are ripe or can be used to make a jam. The fruit is non-medicinal.
The fruit from the p.ligularis species is the most popular fruit from the passiflora species, which is mainly found in warmer climates such as South Africa, South American and the Caribbean. It is commonly eaten as a fruit, as juice or as a flavour in cooking.

Passion flower aids in relief from racing thoughts that are preventing someone from sleep. It does this by acting on the central nervous system, binding to the GABA (gamma-aminobutyric acid) receptors that relax the body. It does this by
- inhibiting GABA reuptake: This prevents the brain from absorbing GABA so it increases the concentration of GABA in the brain. This means there is a more calming neurotransmitter and it helps us to slow down. It DOES NOT affect GABA release.
- binding to GABA-B receptors: binds to receptors in the brain that act as modulators that help to decrease anxiety and addiction withdrawal.
- non-binding to GABA-A receptors: does not bind to other receptors where drugs such as benzodiazepines and alcohol bind so that it does not have any addiction potential.

These various actions remind the body to slow down and decrease stress allowing the body and mind to start to feel sleepy. It is usually the dry extract of the plant that is used in herbal medicines.

Evidence
Passion flower is a well-studied plant that demonstrates efficacious actions for sleep, anxiety and overall relaxation of both. Some of the clinical trials involving passiflora are summarized below.
1. In a double-blind, randomized trial comparing the efficacy of passion flower extract with the pharmaceutical sedative drug oxazepam in the treatment of generalized anxiety disorder (GAD), no significant difference was observed between the two protocols. Oxazepam showed a rapid onset of action with significantly more problems relating to impairment of job performance.
- Overall Passiflora extract is an effective drug for the management of GAD, with a lower incidence of impairment of job performance compared to oxazepam.
2. A randomized, one-sided, blind clinical trial determined the efficacy of Passionflower in reducing anxiety during dental procedures. There was a significant difference in the anxiety levels before and after the Passionflower administration in the Passionflower group. Administration of Passionflower as a premedication is significantly effective in reducing anxiety during dental procedures.
3. Double-blind, placebo-controlled premedication in patients with preoperative anxiety. The NRS anxiety scores were significantly lower in the Passiflora group than in the control group. In outpatient surgery, administration of oral Passiflora incarnata as a premedication reduces anxiety without inducing sedation.
These studies clearly show both the sedative properties and anti-anxiety potential that this plant has.
