The official journal of the American Academy of Pediatrics has an interesting article published on August 6, 2012. It is about a group of doctors who studied 300 children who had upper respiratory tract infections and nighttime coughs. To treat the coughs, some of the children received eucalyptus honey, some citrus honey, and some labiatae honey, and one group received a placebo. The doctors then evaluated cough frequency, cough severity, bothersome nature of cough, and child and parent sleep quality.
Parents of the children who received any kind of honey rated their sleep as better than the parents of children who received the placebo.
Honey may be a good treatment for cough and sleep difficulty associated with childhood upper respiratory infections.
