Reduce inflammation

When used as a supplement, passion fruit peels' high antioxidant content may provide potent anti-inflammatory benefits. Over four weeks, one modest research looked at the effects of a purple passion fruit peel supplement on asthma symptoms. Wheezing, coughing, and shortness of breath was reduced in the supplement group.

In a different trial, participants with osteoarthritis of the knee who took a purple passion fruit peel extract experienced less joint pain and stiffness than those who did not take the supplement. Overall, further study is required since it is still unknown how antioxidants affect pain and inflammation in people with osteoarthritis.
