To remove mucus from the back of the throat, try coughing to clear it, advises Native Remedies. This helps to break up and loosen the phlegm to bring it to the surface. Juice and tea with honey also help to thin out the phlegm to make it easier to cough up.
Some over-the-counter drugs also aid in loosening and breaking up mucus in the throat, including ibuprofen, saline nasal spray, antiseptic for gargling and paracetamol. If the phlegm is caused by an infection, prescription medications are available, according to Native Remedies.
There are also some natural remedies to help soothe the throat and loosen the phlegm further, explains Native Remedies. Standing in a hot shower with the water spraying on the chest area helps to loosen the phlegm. Inhaling the steam from a pot of boiling water is also effective. Throughout the day, it is good to drink as much water as possible as it helps to thin out the mucus.
Since phlegm enters the throat from the nose, it is also helpful to blow the nose regularly, states Native Remedies. Other tips include adding eucalyptus oil to a vaporizer, gargling with warm saltwater, avoiding meat and dairy products and drinking hot liquids such as chicken broth or herbal tea. The person with a phlegm problem should also reduce exposure to paint fumes, household cleaners and cigarette smoke. Spicy foods, including chili peppers and horseradish, help with mucus reduction.
