Long before modern chewable tablets, ancestors used a specialized “acid-buffering” trick for gastritis, peptic ulcers, and acid reflux. This involves consuming raw, extracted potato juice—a practice rooted in the belief that “internal heat” must be neutralized by the cooling essence of the earth.

The Raw Potato Alkaline Shield

While many are familiar with potatoes as a hearty starch, ancient herbalists used Solanum tuberosum as a surgical-grade “internal bandage.” By drinking a fresh, raw potato extract, they aimed to “coat the lining” of the stomach and esophagus. This method uses the plant’s unique alkaline salts—which are destroyed by cooking—to provide a direct, chemical neutralization of excess stomach acid without the need for synthetic aluminum or magnesium.

Benefits

• Acid Neutralization: Raw potato juice is highly alkaline, meaning it physically raises the pH of the stomach environment on contact.
• Wound Healing: It contains specific protease inhibitors that have been shown to help heal the delicate mucous membranes of the stomach lining.
• Anti-Spasmodic: The high potassium content in the raw juice helps relax the smooth muscles of the digestive tract, reducing cramping and “reflux” pressure.

Traditional Raw Potato Stomach Buffer

Ingredients

• 2 Medium Red or Yellow Potatoes (avoid any with green skin or sprouts, as these are toxic)
• 1/2 cup Pure Water
• A Fine Grater or a Juicer
• A piece of clean Cheesecloth

Instructions

1. Wash the potatoes thoroughly and remove all the “eyes” or dark spots. Do not peel them, as much of the mineral content is near the skin.
2. Grate the potatoes finely into a bowl using the smallest holes on your grater.
3. Place the grated pulp into a piece of cheesecloth and squeeze it vigorously over a glass to extract the juice. (Alternatively, run the potatoes through a mechanical juicer).
4. Add the 1/2 cup of water to the juice to dilute the earthy taste.
5. Let the juice sit for 2 to 3 minutes; you will see a white sediment (starch) settle at the bottom.
6. Drink the clear/cloudy liquid at the top, leaving the heavy starch at the bottom.
7. Crucial: Drink this on an empty stomach, at least 30 minutes before breakfast or dinner.
8. Consume the juice immediately after making it; if it turns dark brown or black from oxidation, discard it and make a fresh batch.
9. Take 1/2 cup twice daily during a flare-up of heartburn or stomach pain to keep the “internal fire” at bay.
