Salt Water Gargle
This works effectively for adults, teens, and children who know how to gargle. This mixture is simply salt dissolved in warm water. Salt water is potent for expelling phlegm and mucus behind the throat. Phlegm and mucus account for one of the reasons for persistent or recurrent coughs. All you have to do is prepare the mixture and gargle (let the mixture sit at the back of your throat for a while) in your mouth for a few minutes, after which you’d spit it out. This is why this remedy isn’t effective for children, they can’t gargle, and drinking saltwater is dangerous for them.
Probiotics
This is not a direct remedy for coughing. Nonetheless, it is a potent boost for the immune system and balances bacteria in the gut. Research [15] accounts for Lactobacillus (a type of probiotics) as an effective preventive measure against the common cold. Probiotic supplements are a better source of probiotics than food. This is because probiotic food sources [16] may only contain a small amount of probiotics.
