Children who take a small amount of buckwheat honey prior to sleeping may experience symptomatic relief from cough, states WebMD. The all-natural product Honey Don't Cough, which contains buckwheat honey, is mild enough for children but also potent enough to treat adult coughs.
As of 2015, the details regarding the mechanism of action of honey in the body remains unexplained, notes Honey Don't Cough. Experts believe that honey's therapeutic effects stem from its demulcent properties, which soothes the throat in cough patients. The compound also has anti-microbial properties and contains a high amount of anti-oxidants that combat harmful substances.
Buckwheat honey also boosts the immune system by stimulating the production of cytokinene cells. It should be noted that honey should not be administered to children under 1 year of age since it can lead to botulism, suggests WebMD.
