The sedative effects of this plant are largely due to its ability to modulate the activity of neurotransmitters in the brain, promoting relaxation and reducing anxiety. The anti-inflammatory properties of Passiflora incarnata are thought to be mediated by flavonoids, which have been shown to inhibit the production of pro-inflammatory cytokines. The antimicrobial activity of this plant is attributed to its volatile oils, which have been demonstrated to exhibit bactericidal and fungicidal properties against a range of microorganisms.
Additionally, the antispasmodic properties of Passiflora incarnata are believed to be responsible for its ability to relax smooth muscle and reduce muscle spasms.
What are the medicinal constituents this herb?
The most important healing constituents of Passiflora incarnata are kaempferol, a flavonoid that exhibits antioxidant and anti-inflammatory properties by scavenging free radicals and inhibiting pro-inflammatory enzymes.
Quercetin, a potent flavonoid, is also present in Passiflora incarnata, displaying anti-inflammatory and antioxidant activities, as well as inhibiting the production of pro-inflammatory cytokines and enzymes. Isovitexin-2'-o-glucoside, a flavonoid glycoside, has been reported to possess sedative and anxiolytic effects by modulating the activity of GABA receptors in the brain. Harmane, a β-carboline alkaloid, is found in Passiflora incarnata and has been shown to exhibit sedative and anxiolytic properties, likely due to its ability to modulate the activity of GABA receptors and inhibit the release of neurotransmitters.
Passiflorine, a flavonoid, is also present in Passiflora incarnata and has been reported to exhibit sedative and anxiolytic effects, as well as antispasmodic and anti-inflammatory activities.
What are the main herbal preparations this herb?
The main herbal preparations of Passiflora incarnata are tincture, tea, capsules, infusion, and salve.
Tinctures are prepared by soaking the dried plant in a solvent, such as ethanol, to create a concentrated extract. Tea is prepared by steeping dried or fresh plant material in hot water. Capsules and infusions are prepared by encapsulating or steeping dried plant material in hot water, respectively.
These preparations are used to harness the sedative and anxiolytic properties of Passiflora incarnata, which is attributed to its flavonoid and alkaloid content, particularly harman and harmine.
What are the possible side effects of using this herb improperly?
The possible side effects of using Passiflora incarnata improperly include exacerbating anxiety due to its sedative properties which can be overwhelming if taken in excessive amounts, triggering seizures in individuals with a history of seizure disorders as it can lower the threshold for seizure activity, worsening insomnia in some individuals as it can affect the sleep-wake cycle and cause dependence, aggravating insomnia due to its sedative properties causing a rebound effect, and lowering blood pressure as it can cause vasodilation and interact with medications that lower blood pressure.
This is because Passiflora incarnata contains flavonoids and alkaloids that can affect the central nervous system and interact with medications. The sedative properties of Passiflora incarnata are attributed to its active compounds including passifloric acid and flavonoids. Excessive consumption can lead to adverse effects including those listed above.
Individuals with pre-existing medical conditions should consult a healthcare professional before using Passiflora incarnata.
