Home remedies described by our editors from research: where they come from, what is known, the risks and when to see a doctor.
Peppermint leaf infusion is a traditional remedy for indigestion and bloating, recognized by the EMA based on long-term use rather than clinical studies; however, peppermint may exacerbate heartburn and reflux, and the oil should not be applied to the faces of infants and young children.
Garlic is a popular home remedy for colds, but there is very little research: Cochrane found one study and deemed the evidence insufficient; supplements may increase the risk of bleeding, and raw garlic applied to the skin can cause burns.
Ginger is a traditional remedy for nausea; the EMA recognizes it for motion sickness, but the NCCIH finds the evidence inconclusive, and it may cause heartburn and gastrointestinal discomfort.
Gargling with warm salt water is recommended by the NHS and CDC as a home remedy for sore throat, though there is limited research specifically on salt; the solution should not be swallowed, and children should not attempt this method.
Ice is recommended for fresh sprains and bruises, while heat is suggested for stiffness and muscle pain; the NHS endorses these methods, but research is limited, with primary risks being frostbite and burns from heat packs.
Inhaling steam from hot water during a cold and nasal congestion has not been shown to provide clear benefits, and burns from boiling water occur in both children and adults.

Homemade onion syrup is a traditional remedy without clinical studies confirming its effectiveness for cough; honey-sweetened syrup should not be given to children under 1 year old.
