Teas made from the silica -rich green tops of the oat plant are said to have a diuretic effect that lowers blood levels of uric acid. If my other natural approaches failed, I'd be sure to try this one. Olive has a reputation as a diuretic dating back to biblical times. In 1993, a Japanese researcher showed that about four cups of olive leaf tea a day for three weeks increased daily urine output by 10 to 15 percent, lowering uric acid levels in the blood and increasing uric acid in the urine. I would not hesitate to try this one myself.
Pineapple contains bromelain , an enzyme that helps break down protein.
Naturopathic physicians often recommend pure bromelain , which can be purchased at health food stores, to reduce inflammation and swelling. Bromelain clearly works if you inject it into swollen tissue, but the effectiveness of the ingested enzyme has been controversial. It's probably worth trying, however. My preferred way to get bromelain is in an occasional glass of pineapple juice. One scientific study showed that stinging nettle increases uric acid secretion, at least in ducks.
