For persistent dry coughs, natural remedies can often provide relief alongside medical guidance. Parents recommend a mixture of mildly heated ajwain leaf and tulsi leaf juice with a little honey, or an 'onion-honey' concoction—layering sliced onion and honey in a jar for 3-4 hours and giving the resulting syrup in small spoonfuls. Additionally, running a humidifier in the sleep area helps combat dryness, and for phlegmy coughs, spending time in a steamy bathroom can help loosen congestion.
