Natural Diuretics: 14 Amazing Teas for Water Retention

Updated in October 2023
Scientifically proven

Teas are a great way to consume natural diuretics, as they contribute to overall fluid intake which results in an increased production of urine. However, there are some plants that inherently contain a stronger diuretic effect due to the substances in their composition. These teas promote the elimination of accumulated fluid, which helps to relieve swelling, bloating and water retention.

Diuretic teas are also a great, natural way to complement the treatment of many health conditions, like urinary tract infections for example. These teas increase flow through the urinary tract, which helps to clear out bacteria faster.

Ideally, if you are looking to achieve a therapeutic goal (e.g. to help treat a UTI, or to decrease fluid retention), these natural diuretics should only be taken under the monitoring of your doctor. Being open with your doctor can prevent any interactions that the tea may have with prescription medication.

Which teas are naturally diuretic?

Teas that contain natural diuretic properties include:

1. Green tea

Green tea is rich in caffeine, which is a substance that has natural diuretic properties. Even though just one cup of tea does not contain the amount of caffeine necessary for this, having three cups a day can increase your production of urine and help to eliminate excess fluid in the body.

Learn more about the health benefits of green tea and how to consume it.


  • 1 tablespoon of green tea leaves
  • 1 cup of boiling water

How to prepare

Place the leaves in a cup, pour the boiling water over them and allow to soak for three to five minutes. Then strain the tea and let it cool down. Drink three cups of this tea throughout the day. The greater the soaking time, the higher the caffeine content. However, keep in mind that if the tea infuses for a long time, it may taste more bitter. You are advised to allow the leaves to soak for three minutes and then taste the tea every thirty seconds until you achieve your desired flavor. 

Because green tea has caffeine, it should not be taken by children. Additionally, people who have difficulty sleeping should avoid taking it, especially in the evening and at night.

2. Parsley tea

Parsley tea is one of the most popular home remedies to treat water retention. Studies done on animals show that parsley has a diuretic effect on animals, as it increases overall urine production [1].

Also, parsley contains flavonoids which are compounds that can bind to adenosine A1 receptors, as shown in another study [2]. This binding decreases the effect of adenosine, resulting in increased urine production. 


  • 1 bunch or 15 grams of fresh parsley with stems
  • 1/4 lemon
  • 250 ml of boiling water

How to prepare

Wash and chop up the parsley. Add the parsley to a cup with the boiling water and let it soak for five to ten minutes. Then, strain the infusion, let it cool down. You can drink this tea several times a day. 

Ideally, parsley tea should not be taken by pregnant women or by people who take anticoagulants or other types of diuretics. Check out the other health benefits of parsley and how you can use it to complement treatment for other conditions.

3. Dandelion tea

Dandelion is another popular herb used to increase the production of urine and treat water retention. This plant works as a natural diuretic because it is rich in potassium, which is a type of mineral that acts in the kidneys and promotes urine excretion 


  • 15 g dandelion leaves and roots
  • 250 ml of boiling water

How to prepare

Pour the boiling water into a cup and then add the dandelion. Let this soak for 10 minutes. Strain the infusion out and drink the tea two to three times a day. 

This plant should not be used if you are pregnant or if you have a history of gallbladder issues or bowel obstruction.

4. Horsetail tea

Horsetail tea is another natural diuretic that is used a lot in traditional medicine and although there is not much recent research about this plant, a review done in 2017 states that the diuretic effect of horsetail can be compared to hydrochlorothiazide, which is a diuretic produced in the lab. Learn more about the health benefits of horsetail tea as well the possible side effects.


  • 1 teaspoon of horsetail
  • 250 ml of boiling water

How to prepare

Place the horsetail in a cup with boiling water and let it sit for 5 to 10 minutes. Then strain and let the tea cool down. Drink this tea three times a day.

Even though it is not completely established whether horsetail increases the excretion of minerals through urine, we recommend you only ingest this herbal tea for a maximum of 7 consecutive days to prevent mineral imbalances. This tea should not be taken by pregnant or breastfeeding women.

5. Hibiscus tea

Hibiscus tea seems to increase the quantity of urine produced significantly and, according to a study on mice [3]Its effect is similar to that of synthetic diuretics produced in the lab, such as furosemide and hydrochlorothiazide.  

In addition, another study [4] also completed on mice concluded that the composition in anthocyanins, flavonoids, and hibiscus chlorogenic acid seems to regulate the activity of aldosterone, a hormone that controls the production of urine.

How to prepare

Put the hibiscus in the hot water, cover, and let it sit for 10 minutes. Then strain the infusion and drink it throughout the day.
