If you enjoy it and it fits your dietary needs, you can consider it a beverage. Plain water remains a suitable everyday choice—you do not need barley water to follow a kidney-stone prevention plan.

What Is Barley Water?

Barley water is the liquid obtained by cooking barley in water, usually followed by straining. Recipes differ in the amount of grain, cooking time and added ingredients.

It is not the same as eating a serving of cooked barley. You should not assume that a strained drink contains the same amount of fibre or other nutrients as the whole grain.

Commercial versions may contain added sugar, flavourings or other ingredients, so check the label.

What Does the Research Show?

Barley is widely used as a traditional stone remedy, but popularity does not demonstrate effectiveness.

A 2024 survey documented the use of barley and other nonmedical remedies. It was a survey of people’s practices, not a controlled test showing that barley water removes stones. The researchers called for clinical studies of effectiveness and safety.

There has also been research on a multi-ingredient herbal formulation containing barley alongside other plant extracts. Results from that formulation cannot establish that homemade barley water alone produces the same effects.

The practical distinction is that drinking fluid and treating an existing stone are different things.

Can Barley Water Dissolve or Flush Out Stones?

There is no established barley-water recipe or dose that reliably dissolves kidney stones.

Some small stones pass naturally. If someone passes a stone after drinking barley water, that timing alone does not prove the drink caused it.

Treatment decisions depend on the stone’s size and location, symptoms, and whether it is causing obstruction or infection. Some stones require medication or a procedure.

Do not use a barley-water routine to postpone recommended treatment or follow-up.

For broader context, read our home-remedies evidence guide.

How to Make Plain Barley Water

The following is a beverage recipe, not a kidney-stone treatment prescription.

Ingredients

• 2 tablespoons of food-grade pearl barley.
• Approximately 750 mL of drinking water.
• An optional squeeze of lemon for flavour.

Method

1. Rinse the barley.
2. Put it in a saucepan with the water.
3. Bring to a boil, then reduce to a gentle simmer.
4. Follow the barley packet’s cooking instructions, adding water if needed.
5. Strain into a clean container and allow it to reach a comfortable drinking temperature.

You can serve it warm or cooled according to preference. There is no established stone-treatment advantage to drinking it warm.

Keep it unsweetened. Adding salt, including pink salt, is unnecessary and increases sodium intake.

How Much Should You Drink?

There is no evidence-based daily dose of barley water for kidney stones.

If you choose to drink it, count it within your total fluid intake, rather than adding several extra cups to an existing target.

Your appropriate fluid intake depends on your health and circumstances. People with a prescribed fluid restriction should follow their care team’s instructions.

Our water-intake guide explains the difference between how much you drink and how much urine you produce.

If you explore the Kidney Stone Removal Report, check any suggested drinking schedule against your own medical advice.

Who Should Avoid or Review Barley Water?

People With Celiac Disease

Barley contains gluten. Homemade barley water should not be considered gluten-free simply because the grain has been strained out.

Choose a suitable alternative, such as plain water, if you need to avoid gluten.

People With a Barley Allergy

Avoid barley-containing drinks if you have a known barley allergy.

People Following a Fluid Restriction

Barley water still counts as fluid. Do not use it to exceed a limit prescribed for a medical condition.

People Monitoring Carbohydrate Intake

Check packaged drinks for added sugar and total carbohydrate. Homemade preparations vary, so avoid assuming that every barley drink has the same nutritional content.

What Helps With Long-Term Prevention?

Adequate fluid intake is one part of prevention. Depending on your stone type, your plan may also include reducing sodium, maintaining appropriate dietary calcium or adjusting particular foods.

Barley water does not replace these measures, prescribed medication or testing.

When to Seek Urgent Help

Seek urgent medical assessment for suspected kidney stone symptoms with:

• Fever or chills.
• An inability to urinate, or only passing a very small amount.
• Severe or uncontrolled pain.
• Persistent vomiting.

Do not respond to these symptoms by repeatedly increasing barley water or other drinks.

Frequently Asked Questions

How many days does barley water take to remove a stone?

There is no proven timeframe. Do not rely on promises that it removes stones within a set number of days.

Is barley water better than plain water?

There is insufficient clinical evidence that homemade barley water is superior to plain water for stone prevention or passage.

Does adding lemon make it dissolve stones?

No established evidence supports that claim. Lemon can add flavour, but the combination is not equivalent to prescribed stone treatment.

Can barley water treat burning urination?

It should not be used as treatment for unexplained urinary burning. Infection and other causes may need assessment.

Can I drink it every day?

There is no medical need to do so for kidney stones. Whether it fits your routine depends on your dietary needs, tolerance and any fluid restriction.

The post Barley Water for Kidney Stones: Benefits, Evidence and Precautions appeared first on Kidney Stone Removal at Home.

If you’ve searched for natural kidney stone solutions, you’ve probably seen this one: mix lemon juice and olive oil to dissolve the stone.

Some swear by it. Others call it a myth.

So what’s the truth? Let’s break down the science, the tradition, and whether this home remedy deserves a spot in your toolkit.

Explore the full breakdown of home remedies that actually work here

What Is the Lemon + Olive Oil Remedy?

The basic version goes like this:

• Mix 2 tbsp of lemon juice with 2 tbsp of olive oil
• Drink the mix on an empty stomach
• Follow with a full glass of water
• Repeat 1–2x daily for a few days

The idea is that lemon helps break down calcium stones and olive oil lubricates the urinary tract, helping the stone pass more smoothly.

What Lemon Juice Actually Does

Lemon is rich in citrate, a natural compound that:

• Inhibits calcium stone formation
• Binds to calcium, preventing it from forming crystals
• May help dissolve very small stones

BUT: You need consistent intake—1–2 lemons daily—for several days or weeks to see a citrate effect.

What About Olive Oil?

Here’s where the science is less convincing.

• Olive oil is healthy and anti-inflammatory
• But there’s no evidence that it helps dissolve stones
• It may soothe the digestive tract, but doesn’t reach the kidneys

Still, it’s harmless in small amounts—just don’t overdo it (more than 2–3 tbsp/day may upset digestion).

What to Watch Out For

• Too much lemon can erode tooth enamel or upset the stomach
• Too much oil can cause nausea or diarrhea
• If your stone is large or causing severe pain, seek medical attention

This remedy should not replace hydration, movement, or other proven strategies.

How to Use This Remedy Safely

If you want to try it:

1. Mix 2 tbsp fresh lemon juice + 1 tbsp extra virgin olive oil
2. Take it once per day, after a light meal
3. Follow with warm water or herbal tea
4. Continue for 3–5 days, while also drinking 2.5–3L of water daily

Pair it with:

• Walking or gentle stretching
• Lemon or basil water throughout the day
• Heat therapy for pain relief if needed

Better Results With a Full Routine

Instead of relying on one mixture, use multiple home remedies in a structured routine:

• Lemon juice + water (spread across the day)
• Barley water for flushing
• Basil tea to reduce inflammation
• Chanca Piedra or coriander seed tea for support

The post 🍋Lemon Juice and Olive Oil for Kidney Stones – Myth or Miracle? appeared first on Kidney Stone Removal at Home.

Lemon juice deserves a separate discussion: researchers have studied it for preventing recurrent stones. However, possible prevention benefits do not establish that a lemon-and-oil mixture can remove a stone already causing symptoms.

Why Is This Remedy So Popular?

The usual explanation is that lemon juice breaks down the stone while olive oil helps it slide out.

That explanation confuses digestion with the urinary system. Swallowed oil enters the digestive tract and is digested and absorbed. It does not travel as a layer of oil through the ureters—the tubes connecting the kidneys to the bladder.

A person may pass a small stone after trying the mixture, but timing alone does not show that the remedy caused passage.

What Can Lemon Juice Actually Do?

Lemons contain citric acid. Citrate in urine can bind calcium and help inhibit the formation and growth of certain crystals.

However, the effect of drinking lemon juice on urine chemistry varies. Lemon juice is not interchangeable with a prescribed dose of potassium citrate.

The useful question is whether it can contribute to a prevention plan—not whether its acidity will directly “melt” a stone inside the kidney.

What Did a Clinical Trial Find?

A randomised trial involving 203 people with recurrent calcium oxalate stones compared a standard diet with or without fresh lemon juice supplementation.

Over two years, stones recurred in 21 of 100 participants assigned lemon juice and 32 of 103 assigned no supplementation. The difference did not reach statistical significance at the main two-year endpoint.

Adherence to lemon juice declined over time, and gastrointestinal problems were more frequent in the lemon-juice group.

The findings leave uncertainty about the size of any prevention benefit. Crucially, this trial did not test an olive-oil mixture or treatment of an acute stone attack.

Does Lemon Juice Dissolve Calcium Stones?

Lemon juice is not an established treatment for dissolving existing calcium oxalate stones.

Some uric acid stones can be dissolved by medically supervised treatment that changes urine pH. That requires identifying the likely stone type, choosing appropriate medication and monitoring the response.

It should not be confused with drinking lemon juice or following a home “flush.”

Read more about uric acid kidney stones and calcium oxalate stones.

Does Adding Olive Oil Help?

There is no established clinical benefit from adding olive oil to lemon juice to remove a kidney stone.

Olive oil can be used normally in meals, but taking it as a medicinal “shot” has no proven stone-passage dose or treatment schedule.

Instructions to take the mixture on an empty stomach, repeat it for several days or increase the amount if nothing happens are not validated kidney-stone protocols.

You do not need to add oil to water or lemon water for hydration.

If you explore the Kidney Stone Removal Report, discuss any suggested remedy routine with your clinician before changing your treatment.

Can You Drink Lemon Water Instead?

If you enjoy it and tolerate it, unsweetened lemon water can make regular drinking more appealing. Adding fresh lemon juice to water is included in some stone-prevention guidance.

Treat it as an optional part of your drinking routine. Do not assume that more lemon produces better results or that it replaces prescribed citrate.

Practical considerations include:

• Dilute lemon juice rather than drinking concentrated shots.
• Avoid routinely adding sugar.
• Count the drink within your total fluid allowance.
• Reduce or stop it if it causes digestive discomfort.
• Discuss persistent tooth sensitivity with your dentist.

Frequent exposure to acidic drinks can erode tooth enamel. Avoid holding or swishing the drink around your mouth, and rinse with plain water afterward.

For fluid targets and restrictions, see how much water to drink for kidney stones.

What Should You Do if You Currently Have a Stone?

Ask your treating clinician whether observation is appropriate and how you should manage symptoms.

The plan depends on the stone’s size and location, your symptoms, and whether infection or obstruction is present. Some small stones pass without a procedure; others require medication or removal.

Useful questions include:

1. Is it safe for me to wait for this stone to pass?
2. What pain treatment should I use?
3. Should I collect the stone for analysis?
4. When do I need follow-up?
5. Which symptoms mean I should seek urgent care?

Our kidney stone pain-relief guide explains supportive care and its limits.

When to Seek Urgent Medical Help

Seek urgent assessment for suspected kidney stone symptoms with:

• Fever or chills.
• An inability to urinate, or only passing a very small amount.
• Severe or uncontrolled pain.
• Persistent vomiting.

Do not delay care while trying lemon juice, olive oil or another home mixture.

Frequently Asked Questions

How much lemon juice and olive oil should I take?

There is no established treatment dose for the mixture. Internet recipes should not be treated as medical instructions.

How quickly will the mixture work?

There is no proven time to stone passage. Promises of results within hours or a few days are not reliable.

Is extra-virgin olive oil more effective?

No clinical evidence establishes extra-virgin olive oil as an effective kidney-stone treatment.

Can lemon water replace potassium citrate?

Do not make that substitution yourself. Your prescribed treatment may have a specific urine-chemistry goal that lemon water does not reliably achieve.

Does passing a stone afterward prove the remedy worked?

No. Small stones sometimes pass naturally. A personal experience cannot establish whether the mixture caused that outcome.

Should I avoid lemon and olive oil in food?

There is no need to avoid normal culinary use solely because the combination is not a proven stone remedy. Food use and treatment claims are different questions.
