10 home remedies that help to reduce phlegm from your chest & throat
8) Warm compress
Try soaking a washcloth in hot water and laying it over the affected areas of your body—the warmth will heat up and liquify the mucus.
9) Essential oils

Natural Living Ideas suggests making use of a diffuser to waft the aroma of essential oils throughout your room. Eucalyptus, peppermint, and rosemary are all essential oils with decongestant properties that help to open the airways.
10) Hot drinks

You might have noticed a common thread throughout these remedies—many of them include a glass of warm water. Natural Living Ideas emphasizes the importance of drinking hot drinks while you’re under the weather. They’re comforting and keep you hydrated, but they’re also effective in loosening mucus from your throat and chest. You can have warm water with lemon, herbal teas, or even a cup of chicken broth. This isn’t an old wive’s tale—researchers have tested the effects of hot and cold drinks on people suffering from the flu, and found that those who were given a hot drink experienced instant and prolonged relief from their flu symptoms.
Stubborn phlegm in your chest and throat is frustrating, and prolonged coughing in an attempt to get it out can irritate the walls of your throat and hurt your chest and ribs. Try these natural home remedies instead to warm and soften the mucus, allowing it to travel more easily through your airways and out of your body.
