You’re likely here because you feel like a jagged, miniature asteroid is trying to work its way through your urinary tract. It’s a pain that people often compare to childbirth or being stabbed from the inside out. When that level of agony hits, you start looking for natural ways to cure kidney stones because, honestly, the thought of surgery or a lithotripsy procedure is terrifying.
I’ve seen people try everything from drinking gallons of apple cider vinegar to literally jumping off ledges hoping the impact will shake the stone loose. Some of it is based on solid urological science; some of it is basically just urban legend.
Most kidney stones are calcium oxalate. That’s a fancy way of saying your urine is too concentrated with waste products. When you don't have enough liquid to flush out these minerals, they find each other, bond, and form crystals. Over time, those crystals grow into stones. If you catch them when they’re small—we’re talking under 5mm—you have a decent shot at passing them without a surgeon’s help.
The Hydration Myth vs. The Reality
Everyone tells you to drink water. Obviously. But most people do it wrong.
If you already have a stone stuck in the ureter, chugging three gallons of water in an hour isn't necessarily going to "push" it out like a waterslide. In fact, if the stone is fully obstructing the flow, you’re just going to put massive pressure on your kidney and cause more pain. The trick to natural ways to cure kidney stones is consistent, high-volume hydration over days and weeks.
You need to be pee-ing out about 2 to 2.5 liters of urine a day. To do that, you have to drink more than that. If your urine looks like apple juice, you’re losing. If it looks like water, you’re winning.
Why Lemon Juice is Your Best Friend
Citrate is the secret weapon here. Citric acid binds with calcium in your urine, which prevents it from binding with oxalate. Essentially, it stops the stone from getting bigger and can sometimes help break down the outer layers of existing stones.
According to various studies, including research often cited by the National Kidney Foundation, lemonade therapy can decrease stone formation rates. But don't buy the store-bought stuff loaded with sugar. Sugar actually increases your risk. You want real, squeezed lemons. Mix half a cup of concentrated lemon juice with water throughout the day. It’s sour, it’s intense, but it works.

The Oxalate Trap
You’ve probably been told to eat your greens. Spinach is great, right? Not for stone formers.
Spinach is an oxalate bomb. If you are trying to find natural ways to cure kidney stones, you have to look at your diet with a magnifying glass. Rhubarb, beets, almonds, and even certain types of soy are incredibly high in oxalates.
Here is the weird part: you shouldn't cut out calcium.
It sounds counterintuitive. If your stone is made of calcium, why eat more? Because when you eat calcium and oxalate-rich foods together, they bind in your stomach and intestines before they ever reach your kidneys. This means they leave your body through your stool instead of your urine. If you eat a handful of almonds, have a piece of cheese or a glass of milk with it. It’s a game-changer.
Chanca Piedra: Does the "Stone Breaker" Actually Work?
If you go into any health food store and ask for a way to pass a stone, they’ll point you toward a supplement called Chanca Piedra (Phyllanthus niruri). The name literally translates to "breaks stones."
Does it work? Kind of.
Some clinical trials, particularly those conducted in Brazil and published in journals like International Braz J Urol, suggest that Chanca Piedra may interfere with many stages of stone formation. It helps relax the ureters, which makes it easier for the stone to slide through. It doesn't necessarily "explode" the stone into dust like a magic wand, but it can make the transit much less miserable.

Dandelion Root and Celery Juice
These act as diuretics. They make you pee more.
- Dandelion root increases bile production and waste elimination.
- Celery juice (or seeds) contains potassium and sodium which can help flush out toxins.
Just be careful. If you’re already on blood pressure medication or diuretics prescribed by a doctor, doubling down with natural diuretics can mess with your electrolyte balance. Always check first.
The Roller Coaster Method (Seriously)
This sounds like a joke, but it actually won a Nobel Prize (the Ig Nobel, but still).
Researchers at Michigan State University found that riding a medium-intensity roller coaster—specifically Big Thunder Mountain Railroad at Disney World—helped patients pass small kidney stones. They used a 3D-printed model of a kidney and found that sitting in the back of the coaster resulted in a nearly 64% passage rate.
The G-forces and the vibrations help "jiggle" the stone out of the renal calyces and into the ureter. If you have a small stone and a theme park nearby, it might be the most fun medical treatment you'll ever have.
Magnesium and Vitamin B6
We focus so much on what to take out of our diet that we forget what to put in.
Magnesium deficiency is incredibly common in people who get chronic stones. Magnesium helps prevent the crystallization of calcium oxalate. If you’re looking for natural ways to cure kidney stones for the long term, adding a magnesium citrate supplement (around 200–400mg daily) can be a massive preventative step.

Vitamin B6 also plays a role. It helps lower the amount of oxalate your body produces internally. Most people don't realize your liver actually makes oxalate on its own, regardless of what you eat. B6 keeps that process in check.
When to Stop the Natural Route
I love natural remedies. But I also love not having permanent kidney damage.
If you have a fever or chills, stop. That means you have an infection. If you can't stop vomiting, stop. That means your body is in shock from the pain. If you can't pee at all, get to an ER immediately.
A stone that is too large (usually over 6mm or 7mm) simply might not fit. You can drink all the lemon juice in the world, but if the "pipe" is 3mm and the "rock" is 8mm, you need a doctor.
Apple Cider Vinegar (ACV)
Does it help? Maybe a little.
ACV contains acetic acid, which can help soften or dissolve stones over a long period. But it’s very hard on your tooth enamel and your throat if you drink it straight. If you use it, dilute two tablespoons in 16 ounces of water. It’s not a miracle cure, but it contributes to the overall acidity balance in your body.
Actionable Steps for Passing Your Stone Naturally
If you're currently in the middle of a stone episode, here is your immediate game plan.
- Hydrate, but don't drown. Aim for 8-10 ounces of water every single hour you are awake. Mix in real lemon juice.
- Move your body. Walking, light jogging, or even jumping jacks can use gravity to your advantage.
- Heat is your friend. A heating pad on your back or side can help relax the muscles around the ureter, which might reduce the spasms.
- The "Bump and Jump" technique. Some people swear by drinking a large amount of water, waiting 30 minutes, and then jumping down from a small step onto their heels. The vibration can help dislodge a stuck stone.
- Switch to a low-salt diet immediately. Sodium forces your kidneys to excrete more calcium into your urine. High salt equals more stones. Period.
- Strain your urine. Use a coffee filter or a plastic strainer. You need to catch the stone if it comes out so you can have a lab analyze it. Knowing exactly what it's made of is the only way to prevent the next one.
The reality is that natural ways to cure kidney stones are mostly about patience and chemistry. You are trying to change the chemical makeup of your urine while using physical movement to guide the stone out. It isn't an overnight fix. It's a process of flushing, vibrating, and alkalizing until that tiny pebble finally makes its exit.
Most people find that once they pass one stone, they never want to do it again. The natural prevention methods—specifically the lemon juice and the calcium-with-oxalate trick—are much easier to maintain than trying to pass a stone once it has already formed. Keep your fluids high, keep your salt low, and keep your lemons handy.
