Xanthine oxidase reduction by quercetin fascinates me.
Can tea, onions, apples and other foods hold the secret for natural gout cures? Lots of scientists are looking, but extracting the active ingredients is hard.
This is really bugging me! But, could bugs be the answer?
Quercetin is a member of the flavonoid group of compounds. These compounds occur naturally in plants, and have been shown to have properties that are beneficial to health.
Quercetin has been studied in several recent investigations to assess it's ability to inhibit xanthine oxidase (XO). Both allopurinol and febuxostat work by XO inhibition.
Unfortunately, the quercetin studies are largely confined to laboratory experiments with occasional animal tests. Animal tests so far have not shown success, and this appears to be down to solubility of quercetin.
Just as I thought I had finished reviewing relevant research, I spotted a mention of quercetin buried deep in a study of large cabbage white caterpillars. So deep, that I cannot assess if quercetin is actually...
