Is cilantro water good for kidneys?


Kidney health is vital for overall wellbeing. The kidneys filter waste and excess fluids from the blood to produce urine. They also help regulate blood pressure, red blood cell production, and maintain electrolyte balance. Kidney disease is a growing health concern, affecting over 30 million American adults. Kidney health depends largely on lifestyle factors like diet, exercise, and managing conditions like diabetes and high blood pressure. This article explores whether drinking cilantro water could benefit kidney health and function.

What is Cilantro Water?

Cilantro, also known as coriander, is an herb popular in many cuisines around the world. It has a bright, citrusy flavor. Cilantro water simply refers to water that has been infused with cilantro. It is made by steeping cilantro leaves and stems in hot or cold water for at least 5 minutes. The water takes on the flavor and potential health benefits of cilantro.

Nutrients and Compounds in Cilantro

Cilantro contains several nutrients and plant compounds that may contribute to kidney health, including:

  • Vitamin C: A potent antioxidant that can protect cells from damage. Also vital for immune health.
  • Vitamin K: Important for blood clotting and bone health. May help regulate calcium in the kidneys.
  • Potassium: Helps control fluid balance. Can help reduce blood pressure.
  • Bioflavonoids: Antioxidants with anti-inflammatory effects in the body.
  • Polyphenols: Powerful plant compounds with antioxidant, anti-inflammatory, and antimicrobial effects.
  • Terpenes: Important constituents of essential oils known to have antioxidant and anti-inflammatory properties.

Many of these nutrients and compounds have specific benefits related to kidney health and function.

Kidney Health Benefits

Research suggests cilantro water may benefit the kidneys in a few key ways:

Improves Kidney Function

Animal studies show cilantro may enhance kidney function by increasing urine output and filtering capacity. The nutrients, antioxidants, and anti-inflammatory compounds in cilantro likely contribute to these kidney-protective effects.

In one study, treating rats with high blood pressure and kidney damage with cilantro extract significantly improved kidney function compared to untreated rats. Human studies are still needed.

Prevents Kidney Damage

Cilantro’s antioxidants, including vitamin C, polyphenols, flavonoids, and terpenes, can prevent kidney damage by neutralizing harmful free radicals.

This helps protect kidney cells and tissues from oxidative stress. Animal studies find cilantro leaf and seed extracts mitigate kidney damage from toxins and high blood sugar.

Lowers Blood Pressure

High blood pressure is one of the leading causes of kidney disease. Cilantro may help lower blood pressure through its diuretic effect and by inhibiting ACE, an enzyme involved in regulating blood pressure.

This blood pressure reducing action can prevent further damage to the kidneys. More human research is warranted.

Removes Toxins and Heavy Metals

Cilantro acts as a gentle diuretic, increasing urine output. This helps flush out toxins and waste from the kidneys. The herb also seems to bind to certain heavy metals in the body, allowing them to be excreted.

Regular cilantro consumption may aid the kidneys’ job of filtering out impurities.

Other Potential Benefits

In addition to the kidneys, cilantro water may also:

  • Boost digestion and relieve bloating
  • Lower blood sugar
  • Improve skin health
  • Promote heart health
  • Have antimicrobial properties to fight infections

So drinking cilantro water can benefit overall health in many ways beyond the kidneys alone.

How to Make Cilantro Water

It’s easy to make refreshing cilantro water at home:


  • 1 cup fresh cilantro leaves and stems, chopped
  • 4 cups filtered water
  • Lemon, lime, or other fruit slices (optional)
  • Sweetener like honey (optional)


  1. Wash cilantro thoroughly and chop roughly.
  2. Add cilantro and water to a pitcher. Stir to combine.
  3. Allow to infuse for at least 5 minutes up to overnight in the fridge.
  4. Strain the cilantro water through a fine mesh sieve into glasses.
  5. Serve chilled over ice. Add lemon slices or sweetener if desired.

You can also simplify the process by adding cilantro to water in a glass and muddling it with a spoon. Let it steep for 5+ minutes before drinking.

How Much to Drink?

There’s no official guidelines on how much cilantro water to drink for kidney health. Since it’s hydrating and low in calories, it’s likely safe to drink up to 2-3 cups per day.

Listen to your body to see how it responds. Start with just 1/2 cup at a time if you’ve never had it before.

Possible Side Effects

Cilantro water is generally safe with very few side effects. Some people dislike the strong flavor. Allergic reactions are also possible but rare.

Drinking large amounts may worsen kidney problems in those with existing kidney disease. As with any herbal water, moderation is key.


Cilantro’s antioxidant and diuretic properties suggest it may aid kidney health and function when consumed as cilantro water. More human research is needed. But adding this fresh, herbal water to your routine is likely safe for most people and provides hydration along with other potential health benefits.

As with any natural remedy, talk to your doctor before trying to manage a kidney condition with cilantro water. But paired with a kidney-friendly diet and lifestyle, it may be a beneficial addition.


In conclusion, early research indicates cilantro water may offer some benefits for kidney health. Cilantro provides antioxidants, polyphenols, and other plant compounds that can protect the kidneys from damage caused by inflammation, toxins, and high blood pressure.

Cilantro water’s mild diuretic effect helps flush the kidneys while supporting normal fluid balance. More human studies are needed, but adding this refreshing herbal water to your diet could be an easy way to support kidney function and overall wellbeing.

Of course, those with kidney disease should check with their doctor before making any major dietary changes like regularly drinking cilantro water. But when paired with proper medical care, it likely has potential as a beneficial complementary therapy.
