Dandelion root and leaves share many virtues. but in general the leaves are more prized for their diuretic properties. They are as strong as some diuretic drugs, and because they are rich in potassium do not lead to potassium deficiency, which can be a serious side effect of drug therapy.
For anyone suffering from water retention, especially if it is due to heart problems dandelion leaf is worth trying.
The root, on the other hand, is one of the best liver tonics, both stimulating and supportive.
For anyone who has liver or gall-bladder problems, or is recovering from such problems dandelion root is a friend to be relied on.
For anyone in fact, who has had a major illness, or had to take a lot of drugs, or has abused drugs or alcohol dandelion will be a solid support on the road to recovery.
