Garlic is a popular herbal alternative therapy. Adverse effects of garlic that have been reported with oral ingestion, inhalation, and topical exposure include smelly breath, body odor, flatulence, esophageal and abdominal pain, small intestinal obstruction, contact dermatitis, rhinitis, asthma, bleeding, myocardial infarction, urticaria, angioedema, anaphylaxis, skin blisters, and ulcero-necrotic lesions. Causality of garlic for specific adverse effects is best established for smelly breath, body odor, and allergic reactions; data regarding other adverse effects are primarily based on case reports. The frequency of adverse effects of garlic and whether they vary by particular preparations are not established.
