Some herbs and dietary supplements have diuretic properties and may help with sodium and water retention. Examples include dandelion, ginger, parsley, hawthorn and juniper.
But proceed with caution before taking any products that have a diuretic effect. Because fluid retention can be caused by a number of medical conditions and some medications, it’s important to talk with your health care provider about possible causes before you try to treat it yourself. Also, some herbs and supplements can worsen medical problems or interact with medications.
