Dandelion leaf is a gentle diuretic, choleretic. It is indicated for oedema, oliguria, gout. Taraxacum leaf is a very potent diuretic and is an excellent remedy for water retention and oedema, particularly when it is of cardiac origin, or hepatogenous oedema (ascites). The usual effect of a drug which stimulates kidney function is a loss of potassium from the body, which aggravates any existing cardiovascular problem. A high level of potassium is particularly desirable when digitalis heart drugs are being prescribed, because if potassium levels fall, the drugs will produce irritability of the heart muscle. Luckily, Taraxacum is one of the best natural sources of potassium and therefore is a perfectly balanced and safe diuretic. Taraxacum leaf may be applied to urinary disorders in general, especially where worsened by the presence of oliguria. (1)
