More Passion Flower Info




TRIBAL AND HERBAL MEDICINE USES
Passion fruit is enjoyed by all rainforest inhabitants -humans and animals alike. Several species of Passiflora have been domesticated for the production of their edible fruit. The yellow, gelatinous pulp inside the fruit is eaten out of hand, as well as mixed with water and sugar to make drinks, sherbet, jams and jellies, and even salad dressings. Indigenous tribes throughout the Amazon have long used passionflower leaves for its sedative and pain-relieving properties; the fruit is used as a heart tonic and to calm coughs.
Passionflower was first "discovered" in Peru by a Spanish doctor named Monardes in 1569 who documented the indigenous uses and took it back to the Old World where it quickly became a favorite calming and sedative herb tea. Spanish conquerors of Mexico and South America also learned its use from the Aztec Indians and it eventually became widely cultivated in Europe. Since its introduction into European herbal medicine systems, passionflower has been widely used as a sedative, antispasmodic and nerve tonic. The leaf infusion was introduced in North American medicine in the mid 1800's as a sedative through native and slave use in the South. It was also used for headaches, bruises and general pain; applying the bruised leaves topically to the affected area. In many countries in Europe, the U.S. and Canada, the use of passionflower leaves to tranquilize and settle edgy nerves has been documented for over 200 years. It was also employed for colic, diarrhea, dysentery, menstrual difficulties, insomnia, neuralgia, eye disorders, epilepsy and convulsions, and muscle spasms and pain.


BIOLOGICAL ACTIVITIES AND CLINICAL RESEARCH
Passionflower (as well as its harmane alkaloids) have been the subject of much scientific research. After almost 100 years of study the sedative, antispasmodic and analgesic effects of this tropical vine have been firmly established in science. The analgesic effects of passionflower were first clinically documented in 1897 while the sedative effects were first recorded in 1904. Antispasmodic, anti-anxiety and hypotensive actions of passionflower leaves were clinically validated in the early 1980's. An extract of the fruit demonstrated anti-inflammatory and tranquilizing effects in animal studies. Also, a leaf extract has also shown to have diuretic activity in rats.
Passionflower has traditionally been used as an aphrodisiac and recent clinical studies with mice have verified this use as well. In a 2003 study, a leaf extract was reported to improve overall sexual function, increase sperm count, fertilization potential and litter size. Its traditional use for coughs has also been recently confirmed. In a 2002 study with mice a passionflower leaf extract was shown to be comparable to the cough suppressant action of codeine.
