Raw potato juice is a traditional remedy for dyspepsia, gastritis, heartburn and reflux. Properly prepared from healthy potatoes, with no green portions, it can soothe the stomach lining and support acid balance. Consume it fresh, 100-150 ml, 1-2 times/day, as an adjunct, not in place of medical treatment.
one portion of ~150 ml
🥔 Ancient European remedy - potato juice has been traditionally used in Germany and Russia as a cure for ulcers and heartburn.
🧪 Pilot studies - there is small clinical research that has shown relief of dyspepsia symptoms after regular consumption of fresh potato juice.
🌱 Potatoes contain natural antioxidants such as chlorogenic acid and vitamin C, which are partially lost during cooking, which is why raw juice retains more active compounds.
⚠️ Solanine - the toxic substance in green or sprouted potatoes can cause severe digestive symptoms, which is why never use them.
💡 Morning Cure - traditionally, the juice is consumed on an empty stomach in the morning for a quick calming and alkalizing effect.
🍹 Clever combination - some naturopathic therapists recommend pairing potato juice with carrot or cabbage juice for enhanced digestive effects.
🧊 Impossible to store - raw juice oxidizes quickly; even in the fridge it loses its properties within hours.
📜 In popular culture - in Romanian villages, the grated or mashed raw potato is also applied externally, on burns or minor skin inflammations.
🔍 Nutritional study - raw potato provides ≈425 mg potassium/100 g, making it one of the most accessible sources of potassium.
➡️ Nutrients (e.g. vitamin C) and sensitive compounds degrade rapidly in contact with air and light; eating on the spot is ideal. In addition, raw potato provides ~319 mg potassium/75 g (≈425 mg/100 g).
➡️ It has a "buffering" effect on stomach acidity and soothes the mucosa, but it cannot completely replace antacids.
➡️ Because it works at lower RPMs, produces less foam and oxidation, and retains more active nutrients.
➡️ Yes, by providing potassium and simple carbohydrates it can support electrolyte balance and overall tone.
➡️ It can relieve symptoms (burning, dull pain), but should be seen as an adjuvant, not as the sole therapy.
➡️ Yes, even small green spots or hidden corners may contain solanine, so thorough cleaning is essential.
➡️ It can be diluted with water or combined with neutral juices (e.g. carrot), but avoid citrus fruits which can irritate the stomach.
➡️ It contains phenolic compounds and antioxidant vitamin C, which may help reduce local inflammation.
➡️ Yes, because stress exacerbates heartburn and potato juice quickly soothes irritated mucous membranes.
➡️ Their digestive system is more sensitive and the risk of exposure to glycoalkaloids is higher.
➡️ There are studies on potato-derived preparations with potential, but no firm evidence for eradication.
