Passionflower was primarily used for nervous anxiety and insomnia, believed to be a sedative or relaxant.  Other reported traditional applications include insomnia, muscle spasm, asthma, menopause, and treatment for narcotic drug and alcohol withdrawal.  Passionflower was not widely used until the 1890s. The dried flowering and fruiting tops were listed in National Formulary (USA) from 1916 to 1936 as a sedative and sleep aid, but in 1978, the Food and Drug Administration banned it from sleep aids after no evidence for its effectiveness was presented during hearings.  It has recently developed quite a following overseas as a smoked or vaporized alternative to Cannabis, due to its sedative and tranquilizing nature. 
 

 

Passion Flowers have been associated with the Crucifixion of Jesus Christ.  The ten petals and sepals, represented ten disciples present at the crucifixion. The three stigma represented three nails on the cross, the five anthers the five wounds of Christ. The many fringes represented the crown of thorns in the passion story. Bosio counted 72 fringes or filaments, which according to tradition, is the number of thorns in the crown of thorns. Interpretations vary in literature.

  
 
The ideal temperature for releasing the most useful active compounds via aromatherapy is reported to be 154C.
 
 
Standardized extracts, tinctures, and solid formulations prepared by a health professional may provide more reliable dosage, however there is no guarantee of strength, purity, or safety of herbal medications, so effects can vary.  As with any medicinal preparation, to ensure the correct dose, patients have been encouraged to measure all liquid medications with an appropriate device such as a dropper, measuring spoon, or cup.  Some forms of Passionflower have been brewed to form a tea for drinking.  Tea made with the stems appears more potent than just the leaves and flowers alone.  Using different formulations of Passionflower together greatly increases risk of an overdose.
 
 
At this time there is not enough scientific information to determine an appropriate range of doses for Passionflower. The appropriate dosage of Passionflower depends on several factors such as the patient's age, health, and other medical conditions. Keep in mind that natural products are not always necessarily safe. Be sure to follow relevant directions on product labels and consult your pharmacist or physician before taking.
