Dandelion Leaf is generally considered a noxious weed but is actually one of the most useful of all herbs and all the parts can be used.
It is the safest and most active plant diuretic with numerous scientific studies done on its efficacy. In one study it was indicated that dandelion exerted a diuretic activity comparable to that of Furosemide (a pharmaceutical diuretic). However, the benefit of Dandelion is that it contains high levels of potassium which is leached from the body through diuresis (a potential side effect of pharmaceutical diuretics).
