Drinking water is a good habit. But what can happen if it gets accumulated in different parts of your body? It would increase your body weight, alter the consistency of your blood and electrolytes, and cause other complications. So, how do you get rid of fluid retention? The answer is – Natural diuretics. I can see the question mark on your face. Read to find out more.

What As A Diuretic And How Does It Work?

A diuretic is a drug that increases urine output. It usually alters sodium excretion from the kidneys. The sodium takes water along with it from the blood – thereby increasing urine output.

As the water content in the blood goes down, so does the pressure on the vessel walls – and this lowers your blood pressure. Due to this action, diuretics are also called water pills.

What Are The Types Of Diuretics?

Depending on their modes of action and the targets, diuretics are divided into three classes:

  • Thiazides – reduce fluids and relax blood vessels. E.g.: Chlorothiazide, Metolazone, and Indapamide.
  • Loop diuretics – act on Henle’s loop in kidneys and treat fluid retention that might otherwise cause heart failure. E.g.: Torsemide, Furosemide, and Bumetanide.
  • Potassium-sparing diuretics – reduce fluid retention without the loss of potassium, and this prevents heart problems. E.g.: Amiloride, Triamterene, and Eplerenone.

Well, it’s nice to know these fancy names. But you may not know their effectiveness (and side effects, if any) until you actually use them. Unfortunately, synthetic diuretics are often known to cause side effects. But hey,

I have an alternative for all of you. How about using natural diuretics that have no side effects? Sounds safer, doesn’t it?

Read on to find out more about these natural diuretics.

10 Best And Safe Natural Diuretics

1. Coffee

Caffeinated beverages like coffee and certain types of tea have a diuretic effect on your body. Compounds called methylxanthines in caffeine affect sodium reabsorption in the kidneys – and you end up losing sodium and other solutes along with lots of water.

When taken in the right amounts, coffee helps lower blood pressure and fluid retention in your body.

2. Herbal Teas

One of the numerous benefits of herbal teas is their diuretic property. These teas find their usage in ancient medicine as treatments for digestive and heart disorders.

Their bioactive components like flavonoids, terpenoids, and poly-alcohols give them antioxidative and anti-inflammatory properties – and in some cases, diuretic properties too. A few of the most commonly used and frequently prescribed herbal teas are made from these ingredients –

dandelion, horsetail, hawthorn, parsley, stinging nettle (Urtica dioica), chamomile, hibiscus, alfalfa, burdock root, calendula, and juniper.

Word Of Caution: Diuretics, when taken in higher quantities, can lead to dehydration. So, moderation is key.

3. Asparagus

Simply put, it is arginine (a basic amino acid that most proteins contain) in disguise. That’s why consuming a good amount of asparagus spears will help you flush out the toxins and excess fluid from your body (a condition also called edema). This will lower your blood pressure and body weight and the risk of UTIs. Asparagus can also boost your fiber intake. But yes,

remember to cook it the right way – do not undercook or overcook.

Time to stock them up!

4. Pumpkin

The only time you care to look at pumpkins is before Halloween. But they find a lot more use in medicine.

Pumpkin (Cucurbita maxima) and its seeds have been used to treat urinary tract infections, bladder infection, and even prostate disorders. The seed oil, along with the fruit, has diuretic properties and also can cure urination troubles like nocturia (1).

5. Watermelon

Watermelon is your kidneys’ best friend as it helps in filtration, clarification, and production of urine.

The pulp contains alkanes and steroids that reduce sodium levels in the blood and prevent the formation of calcium and oxalate stones (2).

Watermelon has other bioactive components like cucurbocitrin and citrallin that dilate blood vessels and maintain blood pressure.

Try making a smoothie with it this time!

6. Celery And Seeds

Belonging to the family of onions, garlic, and leeks (Apiaceae), celery and its seeds also can reduce hypertension and increase heart rate – and this can be linked to its diuretic nature (3).

Celery acts like a potassium-sparing diuretic by restoring the balance between sodium and potassium ions in your body.

So, while making your salad this time, use a simple olive oil-celery seed dressing to rope in all its benefits!

7. Black Cumin Seeds

Black cumin seeds or nigella seeds or black caraway (kalonji) are a staple in Middle Eastern and Asian cuisines. They have also been used in traditional Egyptian medicine to treat diabetes, eye infections, indigestion, toothache, etc.

Along with fighting infections, black cumin seeds can also manage hypertension, asthma, edema (fluid retention), swollen joints, and bloating – thanks to their diuretic nature. This boosts the health of the urinary system, including the kidneys (4).

8. Leafy Greens And Beets

Dietary nitrate, abundantly found in leafy greens, can prevent heart diseases, regulate blood pressure, and maintain the vascular and circulatory systems (5).

Greens like spinach, kale, lettuce, cabbage, pak choi (Chinese cabbage), broccoli, and watercress have a high nitrate content that gives them the diuretic property that helps detox your body.

Beetroot and beet leaf are excellent sources of nitrate and potassium – both mediate diuresis, thereby maintaining your blood pressure.

9. Cranberry Juice

Like celery, cranberry juice is a potassium-sparing diuretic that restores potassium levels in your body while eliminating excess fluid.

This juice has antioxidants and vitamin C that fight microbial infections in the urinary tract and protect your kidneys and bladder.

You can try having dried berries or berry supplements if you find the juice non-palatable.

10. Lemon Water

The best way to start your day might be with a cup of coffee, but I say, lemon water. Yes! Lukewarm water with a slice of lemon does wonders to your body, way more than a hot cuppa.

As they are natural reservoirs of vitamin C, lemons contain the best antioxidant you could ever ask for. Besides this, they help flush out excessive salts and fluids from your body. This simple drink can help you lose weight without any side effects.

You can add a lemon slice or squeeze some lemon juice into a glass of either lukewarm or hot water.

Just observe how fresh and light you’d feel when starting your day with this detox drink.

I’m sure that you’d try to make this simple and rejuvenating drink. As a bonus, let me share some fun facts about natural diuretics.


  • Artichokes are edible flowerheads that have one of the highest levels of antioxidants in vegetables. They also are excellent diuretics.
  • Juniper is yet another natural diuretic that not only prevents fluid retention but also treats indigestion, bloating, and loss of appetite.
  • Hibiscus is not only a beautiful flower to look at. Along with its leaves, hibiscus flower is used to treat bladder infections, fluid retention, and constipation.
  • Peach (Prunus persica) works as a laxative and bladder cleanser. It also helps in reducing weight by flushing out excess fluids from your body.
  • Some diuretics are effective when taken on an empty stomach, and some when taken on a full stomach. Choose carefully.
