Dandelion is generally considered safe for most people when consumed in typical food amounts, but it can cause several side effects and interact with certain medications and health conditions[2][5].
Possible side effects of dandelion include:
- Allergic reactions: Dandelion may cause serious allergic reactions in some people, especially those allergic to related plants such as ragweed, daisies, chrysanthemums, marigolds, or chamomile. Symptoms can include hives, difficulty breathing, swelling of the face or throat, contact dermatitis, and mouth sores[1][2][3][6][7].
- Digestive issues: Some people may experience heartburn, increased stomach acid, diarrhea, or general stomach discomfort. Overdose can result in mild diarrhea[1][3][5].
- Skin irritation: Direct contact with dandelion can cause skin irritation or dermatitis, especially in children or people with sensitive skin[1][6].
- Hypoglycemia: Dandelion may lower blood sugar, potentially leading to hypoglycemia, especially when combined with diabetes medications[1][3].
- Electrolyte imbalance: Due to its diuretic effect, dandelion, especially in combination with prescription diuretics, can increase the risk of dehydration and electrolyte imbalance[1][3][5].
- Liver or kidney concerns: Rare reports include acute liver injury and digital necrosis (rare skin tissue death) after excessive dandelion tea consumption in people with pre-existing conditions[1].
Potential drug interactions:
- Dandelion may interact with antidiabetes drugs, anticoagulants, antiplatelet medications, diuretics, lithium, ciprofloxacin, and medications metabolized by the liver such as substrates of CYP1A2, CYP3A4, and UDP-glucuronosyl transferase (UGT). These interactions can increase or decrease the effectiveness and blood levels of certain drugs[1][3][5][6][7].
- The plant may increase the risk of bleeding when used alongside blood thinners like warfarin or aspirin[3].
Precautions:
- Do not use dandelion without medical advice if you are pregnant, breastfeeding, or giving it to children, as safety is not established[2][6].
- People with allergies to related plants or those with medical conditions, especially involving the liver or kidneys, should consult a healthcare professional before use[2][3][6].
