Suffering from Arthritis? New Passion Fruit Extract May Relieve Your Symptoms
A team of researchers from Iran, the USA and New Zealand recently conducted a study which found that an extract made from the peel of purple passion fruit may reduce pain and stiffness among people suffering from knee arthritis. The findings of the study were published in the October 2010 issue of the journal Nutrition Research.
33 participants were recruited for the study. They were randomly assigned to take a supplement containing 150 mg of an extract made from passion fruit peel or a placebo once a day for two months.
At the end of the study, the researchers used a common osteoarthritis index called the Western Ontario and McMaster Universities (WOMAC) index to measure pain and stiffness among the two groups.
The researchers found that participants given the passion fruit extract showed significant improvements in pain and stiffness compared to the placebo group. They also found a nearly 20% improvement in physical function among the group given the passion fruit extract.
The researchers noted that further studies with larger populations will be necessary to confirm these findings but the antioxidant and anti-inflammatory properties of the passion fruit extract may make it an ideal ingredient for relieving arthritis symptoms.
Currently over 20 million Americans suffer from arthritis and it is the second highest cause of work disability for men over 50 years old. Non-steroidal anti-inflammatory drugs (NSAIDs) are currently the most commonly prescribed medication for arthritis. Some NSAIDs have been linked with gastrointestinal toxicity, increased blood pressure and increased risk of cardiovascular disease.
