Oddly, Commission E did not endorse it. I'm inclined to consider buchu helpful. It contains diosphenol, which may have an antibacterial effect. I like the name quackgrass so much that I feel as if I have to endorse it, especially since I know that this herb is a diuretic with a long folk history of use for bladder and kidney stones. This common weedy grass occurs in almost all 50 states.
Dandelion root is a particularly potent diuretic.
Diuretics don't cure bladder infections, but they help flush urine out of the bladder, and some bacteria along with it. Long clinical experience suggests that this action is helpful in treating bladder infections. Scientists aren't really sure. Two groups of chemicals that have been found in the plant, eudesmanolides and germacranolides, appear to play a role. The potassium in dandelion may also contribute to its diuretic effect.
