Some human trial support for cough (combination products); culinary use is safe.
Limited but encouraging human data for stress and metabolic markers.
Reviews support honey for easing cough, comparable to some OTC options. Medical-grade honey is used on certain wounds.
Yogurt, kefir, sauerkraut, kimchi provide live cultures; emerging evidence links fermented foods to gut-microbiome diversity.
