For years, the potato was the last food I would have associated with the stomach. I thought of it as something to bake, boil, or mash—not something people would turn into a traditional digestive drink.
Then I discovered an old home remedy that appears in several European traditions: fresh potato juice.
People have traditionally used raw potato juice when dealing with burning, acidity, and an uncomfortable stomach. Potatoes contain starch, potassium, vitamin C, and various phenolic compounds, which has led researchers to investigate potato-derived substances for several biological effects.
But there is one crucial distinction: potato juice may be a traditional soothing drink, but it cannot be relied upon to eradicate Helicobacter pylori or permanently cure an ulcer. H. pylori is a bacterial infection, and confirmed infections generally require specific medical treatment.
Why Potatoes Became a Traditional Stomach Remedy
Raw potato is mostly water, carbohydrate, and starch, but it also contains a collection of micronutrients and plant compounds.
When a potato is grated and pressed, the resulting liquid contains dissolved compounds along with suspended starch. It has a surprisingly mild taste when made from a good fresh potato.
Traditionally, people drank small quantities before meals when the stomach felt irritated.
That doesn’t mean the juice coats an ulcer with a permanent protective layer, as some viral explanations claim. But its mild character helps explain why the practice survived in households for generations.
The Helicobacter pylori Connection
This is where things become particularly important.
Helicobacter pylori, usually shortened to H. pylori, is a bacterium capable of colonizing the stomach. Infection can produce chronic inflammation of the stomach lining and is a major cause of peptic ulcers.
Many people with H. pylori don’t initially know they have it.
Others experience burning or aching abdominal discomfort, nausea, bloating, frequent burping, reduced appetite, or symptoms that resemble ordinary indigestion.
Researchers have investigated potato-derived compounds for antimicrobial activity, including against certain bacteria. But laboratory activity isn’t the same as demonstrating that drinking raw potato juice can eradicate H. pylori inside a human stomach.
That’s why a positive H. pylori test changes the situation completely.
Why Eliminating H. pylori Matters
An ulcer isn’t simply a sore stomach.
When H. pylori is responsible, leaving the infection untreated can allow inflammation and ulcers to persist or recur. Long-term infection is also associated with an increased risk of certain stomach cancers.
Fortunately, H. pylori can often be eradicated.
Modern treatment typically uses a combination of acid-suppressing medication and multiple antibiotics, with the exact regimen depending on local antibiotic resistance, previous antibiotic exposure, allergies, and other factors.
After treatment, testing can be used to confirm that the infection is actually gone.
That’s something no homemade drink can reliably establish.
My Simple Fresh Potato Juice Recipe
If I wanted to try the traditional drink simply as a food-based addition to my routine, I would prepare it fresh rather than storing it.
You’ll need:
1 medium fresh potato
About ½ cup water, if needed
Choose a firm potato with normal-colored skin.
Wash and peel it thoroughly.
Never use potatoes that are green, badly sprouted, bitter, or damaged. Green and sprouted potatoes can contain increased concentrations of glycoalkaloids such as solanine, which can cause poisoning.
Cut the potato into pieces and run it through a juicer.
Without a juicer, finely grate the potato, place the pulp into clean cheesecloth, and squeeze the liquid into a glass.
Allow it to settle briefly and drink only a small freshly prepared portion.
I wouldn’t prepare several days’ worth at once.
What About Drinking It on an Empty Stomach?
Traditional recipes frequently recommend potato juice before breakfast or before meals.
There isn’t convincing clinical evidence showing that an empty stomach gives potato juice a special ability to eliminate H. pylori.
If someone enjoys it and tolerates it, a small amount can simply be treated as a food.
But I wouldn’t endure nausea or stomach discomfort because a recipe insists that it must be consumed before eating.
Gastritis Isn’t Always the Same Thing
Another reason the “one drink cures everything” promise doesn’t quite work is that gastritis can have different causes.
H. pylori is one.
Regular use of certain anti-inflammatory medicines can contribute to stomach problems as well. Alcohol, autoimmune conditions, and other factors can also be involved.
That means two people experiencing similar burning sensations may need completely different approaches.
Treating the underlying cause is much more important than simply suppressing the sensation temporarily.
How an Ulcer Actually Heals
This was the part that changed how I thought about stomach remedies.
If an ulcer is associated with H. pylori, successfully eliminating the bacteria allows the stomach or duodenal lining an opportunity to heal, usually alongside acid suppression.
If medication such as an NSAID is contributing to the ulcer, management can be different.
So rather than repeatedly drinking something to quiet the burning while the underlying problem continues, the goal is to identify why the ulcer developed.
The Symptoms I Would Never Treat With Potato Juice Alone
Most indigestion isn’t an emergency, but certain symptoms deserve prompt medical attention.
Vomiting blood, passing black tar-like stools, severe or sudden abdominal pain, fainting, persistent vomiting, unexplained weight loss, or symptoms of significant anemia can indicate bleeding or another serious gastrointestinal problem.
Those aren’t situations for experimenting with a kitchen remedy.
What I Like About the Old Potato Tradition
I still find the recipe fascinating.
A potato is inexpensive, familiar, and nutritionally much more complicated than its plain appearance suggests. The tradition of preparing its juice for an uncomfortable stomach also shows how generations experimented with ordinary foods long before modern gastroenterology existed.
But today we have something those generations didn’t have: the ability to identify H. pylori and specifically eradicate it.
So I would keep the potato drink in its proper place.
Use food for nourishment and comfort. Use testing to discover whether H. pylori is actually present. And when it is, eliminate the infection with a treatment proven to do exactly that.
Because when an ulcer keeps returning, the most valuable remedy isn’t necessarily the liquid that temporarily makes the stomach feel better.
It’s finding—and treating—the reason the stomach became inflamed in the first place.
