Part of the plant used: aboveground parts (leaves and stems)
Because of its great beauty, passionflower is a very popular plant. People use it as an ornamental plant in their garden around the world. It is found in all the Americas. When talking about passionflower, people usually refer to Passiflora incarnata used for its medicinal properties. Interestingly, there is more than 400 different species in the genus Passiflora. The applicable parts of passionflower contain flavonoids, cyanogenic glycosides, alcaloids (harmans), maltol, coumarins and several other substances. Passionflower's properties are usually attributed to its active flavonoids and alcaloids.
Used doses: 60 drops of liquid extract in combination with 0.8 mg of clonidine has been used daily.
There is insufficient reliable information to conclude that passionflower is effective in any other indication.
In 2004, Canada adopted new regulations that control the manufacturing, packaging, labeling and importing of natural health products. The new regulations also include an adverse reaction reporting system. Products that conform to the regulation's criteria are identified with a natural product number (NPN) and can be legally sold in Canada. This number indicates that the product meets specific criteria for safety and purity, not that it is effective for any indication.
Medicinal plant contents vary naturally from plant to plant - just as fruits from the same package may vary in taste and texture. There is no standard to measure the active content of each plant. Thus, efficacy of natural products should be expected to vary from brand to brand as well as from bottle to bottle of the same brand.
