Potato Juice: Heals Gastritis, Lowers Blood Sugar, Cholesterol, Blood Pressure, Uric Acid, and Excess Weight!
Its wide range of healing powers will amaze you!
Potatoes are delicious in many forms: boiled, baked, steamed. In any case, it’s hard to find someone who doesn’t like potatoes.
But today we are interested in the medicinal uses of potatoes—which unfortunately are not well known among people.
Potatoes are incredibly healthy, if we know how to use them properly.
One of the best ways to use the medicinal potential of potatoes is by drinking their juice.
What is so special about potato juice? Its broad range of healing powers will surprise you!
1. Successfully Treats Gastritis
Potato is alkaline (basic), so its juice helps soothe the gastrointestinal tract and treat excess acidity (heartburn).
To treat gastritis: dissolve 1 tablespoon of fresh potato juice in water, drink it half an hour before breakfast, lunch, and dinner. Improvement is almost immediate.
In pilot studies, using fresh, raw potato juice in patients with dyspeptic symptoms (indigestion, burning, discomfort) resulted in significant improvements.

Also, a spray-dried potato juice preparation in animal studies has shown protective effects on the gastric mucosa (lining of the stomach) and reduction of inflammatory markers when ulcers or damage is induced.
2. Heals Stomach Ulcers
If you drink 50 ml (about 2 tablespoons) of raw potato juice in the morning on an empty stomach, and do the same before other meals, significant improvement in stomach ulcers may be achieved. The juice’s alkaline nature and its components help soothe and heal ulcerated stomach lining. Folk medicine supports this use. (Scientific evidence is more limited, mostly animal studies or mechanistic work.)

3. Diabetes Management
Potato juice is also recommended, according to folk sources, because it helps lower blood glucose levels. Some studies on diets that include potatoes (not necessarily juice) suggest effects on insulin and glucose responses.

However, there are also contrary findings: potato consumption in some forms can cause rapid glucose spikes, depending on how it’s prepared (boiled, fried, etc.). So this benefit (for diabetics) must be approached cautiously.

4. Lung Conditions and Smoking-Related Damage
Do you smoke? If so, regular intake of potato juice is said (in folk medicine) to help cleanse the lungs.
Also, potato juice has anti‑inflammatory properties that can help reduce inflammation in general (including in lungs), and may ameliorate some symptoms of lung damage. Scientific work in vitro (cell culture) and in animal models of inflammation supports that potato components reduce pro‑inflammatory cytokines (e.g. IL‑6, TNF‑α) and protect the mucosal lining.
Additional Claimed Benefits
Reduces Cholesterol: Studies in animals have shown that certain potato preparations (whole potatoes, potato pulp, potato peels) can reduce serum cholesterol and triglyceride levels.
Lowers Blood Pressure: Some human trials (e.g. with potato‑based breads) show small reductions in systolic blood pressure; higher potassium content in potatoes might contribute to this effect.
Antioxidant Effects: Potatoes contain vitamin C, polyphenols and other antioxidant compounds that may help in reducing oxidative stress.

Anti‑Inflammatory: Potato juice (or spray‑dried preparations) has shown capacity to reduce expression of inflammatory markers and protect gut mucosa from inflammation in lab or animal studies.
Weight Management: Some claims suggest that potato juice helps with weight loss—either through appetite suppression, improved metabolism, or by influencing fat and lipid metabolism. But strong clinical evidence is limited.

Reduction of Uric Acid: There are folk claims that potato juice lowers uric acid (which causes gout etc.), though scientific studies specifically on this effect are scarce.
How to Prepare the Juice
To gain the benefits, preparation is important:
Use preferably organic potatoes, to avoid pesticide residues.
Wash and peel them. Remove any green parts or spots (green parts contain higher levels of glycoalkaloids such as solanine, which can be toxic in high quantities).

Grate or cut into pieces. You can use a blender or juicer, or simply grate and squeeze the juice out manually.
You may want to leave some starch in the juice, as folk traditions say the starch has the coating and soothing properties.
Dilute: often one tablespoon of fresh juice in ~150 ml (about ½ cup to 1 cup) of water. Drink immediately for best effect.

It is often recommended to take it on an empty stomach (e.g. first thing in the morning), and/or half an hour before meals.

What if You Dislike the Taste?
If the raw potato juice taste is unpleasant:
Mix it with other juices: apple, carrot, pumpkin, etc.
You can also add mild herbs or greens (if they agree with your digestion).
Some recommend warm water instead of cold, or using a small amount of juice and increasing gradually.
Caveats, Warnings, and Scientific Support
While many of these claims are appealing, it’s important to be realistic and cautious:
Many studies showing benefit are animal studies or in vitro (cells), not large randomized controlled trials in humans.
Some human data exist (e.g. for dyspepsia, functional gastric issues), but for serious diseases like ulcers, diabetes, hypertension, more rigorous trials are needed.

Raw potato juice can cause side effects in some people: stomach discomfort, nausea, diarrhea. People with certain sensitivities or kidney or liver conditions should be especially careful.
Tua Saúde
For diabetics: potato juice may increase blood sugar depending on how much and how you prepare it; there is mixed evidence.

Potatoes contain glycoalkaloids (solanine, chaconine), especially in green or sprouted areas; those parts should be removed to avoid toxicity.

Suggested Protocol (Folk Therapy Style)
Here is a protocol, drawn from folk medicine and limited clinical use, not medical guidelines:
For 3‑7 days, follow a mild diet: avoid spicy foods, fatty or very greasy meals, reduce meat/fish if digestion is uneasy. Emphasize plant‑based, easy‑digested foods.
Each morning on an empty stomach, consume about 50‑100 ml of fresh potato juice diluted in water. Wait about half an hour before eating.
Optionally repeat before lunch and/or dinner if well tolerated.
Continue for several weeks (2‑4 weeks), monitoring how you feel, checking for improvements in stomach pain, reflux, digestion.
If symptoms worsen or new ones appear (e.g. stomach cramps, heavy nausea), stop and consult a doctor.
Scientific Findings & What They Support
Here are some of the scientific findings that partially align with these claims:
A pilot human study where patients with dyspeptic symptoms drank potato juice for a week showed significant improvement in GI symptoms and quality of life.
PubMed
Animal studies using spray‑dried potato juice showed suppression of inflammatory cytokines in gastric mucosa, protection against induced ulcers.
Studies on whole potato diets in rats showed decreased cholesterol and triglycerides, improved antioxidant status when compared to diets high in sucrose.
Some human trials (e.g. with potato‑based or potato‑flour enriched foods) hint at reductions in blood pressure, insulin, or cholesterol, though results are small and context‑dependent.
PubMed
Summary
Potato juice is an old folk remedy with many claimed benefits: calming gastritis, healing ulcers, helping with blood sugar control, lowering cholesterol and possibly aiding in weight management and lowering blood pressure. Some of these claims are backed by animal studies and small human trials. Others are less certain or purely traditional.
If you’re interested, you might try using potato juice in moderation, following safe preparation methods, and monitoring your own response. Always check with healthcare professionals if you have chronic health issues or are taking medication.
