What is RelaxHerb?

What is passion flower?

Passion flower (Passiflora incarnata) is a genus of the Passifloraceae family of flowers which grow in Central and South America, as well as southern parts of the United States where it is known as Maypop.

It was widely used by Native Americans in North America to treat anxiety and insomnia. Europeans adopted the use of passion flower as a treatment for epilepsy initially. Over time it started to be used as a sedative.

The name "passion" refers to the religious symbolism which European Christian missionaries instilled upon it. They believed the visual aspects of the flower resembled key aspects of the passion of Christ. Around the world, the name of the flower usually stems from the geographical location at which it is found.

Today, passion flower extract can be found in a number of products marketed to treat anxiety and insomnia. Passion flower extract is available in tablets, liquid, teas and tinctures from pharmacies and health food shops.

How does RelaxHerb work?

RelaxHerb contains passion flower extract which has been traditionally used to treat anxiety, stress and insomnia.

The mechanism of RelaxHerb is unknown, though some scientists believe that passion flower extract increases the amount of Gamma-Aminobutric acid (GABA) in the brain.

Anxiety and stress are often linked to low GABA levels in the brain, so increasing the amount of this inhibitory neurotransmitter is believed to reduce the amount of neurological activity in the brain and treat anxiety.

It is debated whether GABA taken in tablets is able to cross the blood-brain barrier and effectively bind to GABAA receptors in the brain.

Despite the uncertainty of how it works and it's effectiveness, passion flower has been used historically for anxiety and stress, and has been observed to be effective.

The use of passion flower for anxiety is based on traditional use only. RelaxHerb is certified with a Traditional Herbal Registration (THR) which is overseen by the Medicines and Healthcare products Regulatory Agency (MHRA) in the UK.
