Passion fruit peel may alleviate symptoms of asthma

Asthma, or airway inflammation and mucus secretion, can cause wheezing, coughing, and dyspnea. According to the HerbClips article "Efficacy of Purple Passion Fruit Peel Extract in Alleviating Asthmatic Symptoms in Adults," about 17 million people in the U.S. have asthma, an increasing number, which has led to increased interest in the use of nutritional protocols to control asthma.

Purple passion fruit Passiflora edulis peel (PFP) has a history of use with health challenges. In South American folk medicine, extracts of the peel have been used with anxiety, insomnia, asthma, and bronchitis. The extract contains three antioxidants (cyanidin-3O-glucoside, quercetin-3O-glucoside, and edulilic acid) and was "shown to modulate nitric oxide in hypertensive rats."

In a 2008 study with 42 subjects, all participants showed wheeze symptoms at baseline, but only 19.1 % of subjects who took PFP and 78.9% of participants in the placebo group showed symptoms at the end of the study. In addition, "of the approximately 90% and 79% of subjects in the PFP and placebo groups, respectively, with shortness of breath at baseline, approximately 10% and 37%, respectively, had symptoms after treatment. Of the nearly 100% of subjects with cough at baseline, approximately 20% and 50% of subjects in the PFP and placebo groups, respectively, had symptoms after treatment."

These results show that passion fruit peel extract significantly improves asthmatic symptoms after four weeks of usage without adverse effects. The authors of the study concluded that: "PFP extract may be safely offered to asthmatic subjects as an alternative treatment option to reduce clinical symptoms."
