Contraindications

• Excessive consumption of potatoes may cause flatulence.
• The fruits of Solanum tuberosum are not suitable for consumption because they contain the toxic alkaloid solanine.
• Acharya Charaka considered potatoes as one of the most unwholesome tubers.

Side effects

• Excessive Consumption: May cause flatulence.
• Glycoalkaloids: Potatoes contain glycoalkaloids like solanine, which can be toxic in high amounts, especially in green or sprouted tubers. Symptoms of glycoalkaloid toxicity include gastrointestinal issues (abdominal pain, diarrhea, nausea, vomiting) and, in severe cases, neurological symptoms.
• Blood Sugar: Can increase blood sugar levels due to high carbohydrate content.
• Gastritis: Potatoes might not be suitable for individuals with gastritis due to their fiber, carbohydrate, and potassium content.
• Allergy: Allium tuberosum can cause discomfort when overused. Some users report bloating, nausea, or excessive body heat when consuming large quantities—particularly the raw leaves or concentrated decoctions. Those with known sulfur sensitivity or allergies to other Allium species (like garlic, onion, or leeks) should be cautious. In rare cases, skin contact with the leaf juice may trigger mild dermatitis or itchiness.

Interactions

• Anticoagulants: Allium species can thin the blood and therefore combining with medications like warfarin or aspirin should be approached carefully.
• Diabetes Medications: Due to the potential impact on blood sugar levels, caution is advised for those on diabetic medication.

Active compounds

• Starch
