Uses

Oral passion flower products are most frequently used for their effects on the central nervous system (CNS). While not all of their effects are understood, certain chemicals in passion flower may act like a class of prescription drugs known as benzodiazepines. Drugs such as benzodiazepines and herbals such as passion flower increase levels of a neurotransmitter known as gamma-aminobutyric acid (GABA). Neurotransmitters are chemicals that carry messages from nerve cells to other cells. In general, GABA decreases the activity of nerve cells in the brain, causing relaxation, possibly relieving anxiety, and potentially treating insomnia.

In addition, passion flower contains chemicals known as harmala alkaloids, which are thought to block an enzyme involved in depression. This enzyme, monoamine oxidase, breaks down other neurotransmitters--especially dopamine, norepinephrine, and serotonin--which affect mood stability. Blocking monoamine oxidase may increase the amounts of other neurotransmitters, which may improve mood. No large human studies have been performed to prove the effectiveness of passion flower for any CNS uses, however.

Although applying passion flower to the skin is not as common as taking it by mouth, topical forms may help to relieve minor skin conditions such as burns, cold sores, insect bites, razor burn, scrapes, and sunburn. Passion flower products also have been used to alleviate the itching and burning pain of hemorrhoids. Laboratory studies have shown that it possesses some possible mild anti-infective activity, so it may also help to prevent skin surface infections. Again, however, these uses have yet to be proven in human studies.
