Diuretic Teas

Diuretic teas can definitely lower blood pressure.

Western medical protocols for treating elevated blood pressure include the prescription of a number of prescription diuretics. Diuretics lower blood pressure by causing the body to excrete excess fluid through the kidneys. Decreasing the fluid in the body tissues lowers the pressure on the blood vessels, thus lowering hypertension.

It is the diuretic effects of certain ingredients in ‘tea’ that contribute to lowering blood pressure. Most of these ingredients are either herbs or spices which have a diuretic effect. Sometimes these herbs and spices are brewed as single ingredient teas or tisanes. Sometimes a group of these spices is combined for a blended tisane. And sometimes these ingredients are added to leaves from tea bushes to produce a real tea blend.

Here are some of the herbs and spices that have a diuretic effect:


In one study, hawthorn extract was found to be effective for hypertension in people with type 2 diabetes who were also taking prescribed medicines. Participants took 1,200 mg hawthorn extract daily or placebo for 16 weeks. Those taking hawthorn had lower blood pressure than those taking the placebo. Read more about this study here.


Fennel seeds are a gentle and natural diuretic. Fennel seeds make a tasty tea all by themselves, but they are better enjoyed as part of a blended tea where they add complex flavor and aroma notes. One such tea is Ayurvedic Vata Tea.

Parsley Tea

Parsley is a well known herb that is diuretic. Consider adding a bit of parsley to your morning cup of tea. If you mix the flavors artfully, you will get delicious tea plus the blood pressure lowering benefits of parsley.

Other diuretic herbs and spices:

blackberry, black currant, marshmallow, rosemary, sassafras and many more.
