Do take a spoonful of honey (but beware other herbal remedies)
In general, herbal remedies – such as echinacea, or garlic tablets – fail to deliver the goods. The only one to show any promise is honey. A spoonful, taken straight before bed, was found to soothe a cough in three different studies, and proved better than other sugary drinks and cough syrups. Even so, the remedy has mostly been tested on children (although one study suggested that a combination of honey and coffee could help clear persistent cough in adults.) And the mechanism is far from clear. “But with good research [behind it], I think it’s reasonable to try,” Allan says.
