Raw potatoes are primarily seen today as a food that must be cooked to be tasty. However, in the past, in Romanian households and beyond, they were considered a true emergency remedy. Although it is not recommended for frequent consumption in raw form due to solanine, a toxic substance mainly found in the skin and green areas, raw potatoes were used both externally and internally in remedies that still spark interest.
8 Old Uses of Raw Potatoes
1. Raw Potato Juice for Stomach Issues
In the past, when gastric burns or stomach pains occurred after heavy meals, women in villages would squeeze some raw potatoes and offer the obtained juice in small quantities. This remedy was used in cures lasting several days to soothe the fire in the belly, as the elders would say.
This action can be explained by the alkalinity of raw potato juice, which neutralizes excess gastric acid. Modern studies have shown that this juice contains starch, vitamin C, potassium, and compounds with anti-inflammatory and healing effects on the gastric mucosa.
2. Raw Potato Slices on the Forehead for Headaches
One of the simplest and quickest remedies for headaches was applying thin slices of raw potato directly to the forehead. This practice was especially common in mountainous areas, where medicinal plants were scarce during winter.
It is believed that the starch in potatoes has a local calming effect, and the cooling sensation can temporarily reduce the intensity of the pain. Even today, many people use this remedy intuitively.
3. Grated Raw Potato for Minor Burns
In cases of minor burns or cuts in the kitchen, grated raw potato was applied to the skin to soothe the pain. This trick was often used by housewives who did not have access to special creams.
Studies show that the starch and juice from potatoes can reduce inflammation and have a mild antiseptic effect, creating a temporary protective barrier on the skin.
4. Raw Potato Poultices for Rheumatism
In areas affected by rheumatic pain or swelling, grated raw potato was used as a base for poultices. It was applied directly to the skin, wrapped in gauze, and left for 1-2 hours.
This remedy was considered useful due to its cooling effect and the potassium and other electrolytes that helped reduce fluid retention.
5. Applying Potato on Puffy Eyes
For puffy eyelids or dark circles, women would use cold slices of raw potato, applied for 10-15 minutes. This trick was popular before events or celebrations, being considered a little beauty secret.
Research has confirmed that the starch and vitamins in potatoes can reduce inflammation and ocular irritation, at least temporarily.
6. Potato Juice for Acne
Another remedy involved applying potato juice directly to the face, especially on areas affected by acne. It was believed to squeeze out the infection and reduce skin inflammation.
Some studies indicate moderate antibacterial and antioxidant effects in potato juice, but frequent use should be done with caution, especially on sensitive skin.
7. Grated Raw Potato for Warts and Moles
Raw potatoes were sometimes rubbed on warts or moles daily for a week or more. It was believed to draw them out.
Although there is no solid evidence for this effect, some researchers have shown that repeated applications can soften the skin and reduce excessive keratin formation.
8. Raw Potato for Sunburned Skin
On hot days, if someone got sunburned, potato slices were applied directly to the skin. The effect was rapid soothing, and the burning sensation would subside for a while.
This use is supported by the emollient effect of potatoes and their ability to hydrate and cool the skin.
What Do Recent Studies Say?
A study published in the International Journal of Molecular Sciences (2022) analyzed the bioactive compounds in raw potato juice and identified the presence of glycoproteins and phenolic compounds that may have anti-inflammatory and antioxidant effects.
However, researchers emphasize that solanine, mainly found in the skin and in green or sprouted potatoes, can become toxic. High doses can lead to digestive disturbances, dizziness, and, in rare cases, severe poisoning. Therefore, raw potatoes should not be consumed frequently, and their internal use should only be done short-term and with caution.
Contraindications and Precautions
- Do not consume raw potatoes that are sprouted or green. They contain high amounts of solanine.
- It is not recommended for children or pregnant women to consume potato juice without a doctor’s approval.
- People with allergies to nightshades (the family that includes potatoes) should avoid applying them to the skin.
- For external use, raw potatoes should not be applied to open wounds.
- Daily use of potato juice long-term is not recommended, even if diluted.
