diuetics definately help to reduce inflamation which can be of generalized or of any sort may be urinary tract but they cannot control infection.This is because diuretics lack antibiotic properties.
diuretics basically produce excessive urine and hence they reduce inflamation which is due to excessive hydration of a tissue.
These diuretics should not be taken without prescription of a good physician.

Diuretic herbs help increase the flow of urine, useful for clearing infections and inflammations from the urinary tract. Diuretics are also useful in other conditions including heart disease, high blood pressure, obesity, PMS, and menopause.
