Phlegm is a “liquid secreted by the mucous membranes of mammals” that contains lipids, glycoproteins, and immunoglobulins, among others .
It serves several purposes for the body, including keeping tissue surfaces moist to prevent them from drying and cracking .
It also traps bacteria and other harmful invaders before they enter the body and cause infection .
The color of phlegm may also hint at different conditions. For example, if your phlegm is white or grayish, it may signal a sinus or upper respiratory tract infection. Green or dark yellow may reveal bacterial or viral disease.
You need to consult your doctor to diagnose your condition and treatment accurately.
Besides the prescribed medications, you can rely on some home remedies to get rid of phlegm without any risk of side effects.
Home Remedies to Get Rid of Phlegm and Chest Congestion
One of the easiest and simplest ways to expel phlegm is to inhale the steam. It helps to dissolve the sticky substance to make it easier for you to get rid of it.
When it’s no longer sticky, expelling it through the mouth or nose is much easier.
That’s not all that it could do. Steam can also keep the respiratory tract moisturized, which is helpful as a dry environment is a breeding ground for bacteria and viruses.
You can add some volatile oils such as eucalyptus oil or cedar leaf oil to water to improve the efficacy of steam .
But, it’s essential to know that it’s dangerous to use these oils excessively, as they had adverse effects on animal subjects involved in one clinical trial .
If you like, you can use plain water to be safe.
How to take steam to expel phlegm in the throat and chest:
Pour hot boiling water into a basin. Wrap your head with a towel. Move your face close to the bay and inhale the steam. Do this for 10 minutes three times a day.
Another way to loosen phlegm is to take a steam shower twice daily. Turn the battery to full heat. Close the bathroom and stay inside for 10 minutes. Apply lotion on your skin to prevent it from drying out.
If you think steam is the most straightforward remedy for phlegm, wait until you hear about this one.
Water is even simpler, as you don’t have to boil it or turn it into steam to inhale it; you have to drink plenty of water during the day.
Water helps dilute the phlegm, so it’s much easier to expel.
Frequent water intake thins the mucus, so it doesn’t stick to the respiratory tract.
If you don’t like the bland taste of water, try adding slices of fruits. These fruits won’t only improve the flavor but also boost the nutritional content of your beverage.
The most straightforward remedy for phlegm is using water:
Drink eight to 10 glasses of water. To make it more palatable, infuse it with flavor by adding slices of cucumber, lemon, or watermelon into a water pitcher. Let it cool in the refrigerator for at least 30 minutes before drinking. Fluids help soothe an irritated throat and loosen secretions.
A cough caused by viruses or bacteria can cause increased phlegm production in the respiratory tract.
Moreover, honey also works in mild symptoms of another common respiratory ailment called allergic rhinosinusitis, which also causes overproduction of phlegm .
How to use honey for clearing phlegm from the chest and throat:
Combine ¼ tsp of black pepper and one tablespoon of honey. If black pepper is not available, you may use white pepper. Take this mixture twice a day for one to two weeks.
In a glass of warm water, stir in one tsp of honey and lemon juice. Drink solution three times a day for one week.
4. Eucalyptus Oil
The source of this essential oil is the leaves of an evergreen tree from Tasmania and Australia .

Over the years, more and more people have relied on eucalyptus oil as a home remedy for various respiratory ailments, including cough and the common cold.
It is typically added to tablets and syrups and used in vapor baths and inhalation .

5. Lemon Oil
In Ontario, Canada, researchers looked at lemon oil’s role as an expectorant inhalant .
The rabbits had to inhale to assist in the expelling of phlegm that was stuck in their respiratory tract .
The experiment increased phlegm output and, at the same time, reduced the amount of respiratory tract fluid .
Researchers explain that lemon oil’s expectorant properties stimulate the secretory cells in the respiratory airway. As a result, it boosted the volume and concentration of mucus .
An easy way to use lemon oil for phlegm:
Add 2 tsp of lemon juice to a glass of warm water and mix. Pour a drop of lemon oil and 1 tablespoon of honey. Stir well to blend the solution. Drink the solution three times a day for up to one week. After that, it’s better to use warm water instead of cold.

A study conducted in 1970 shows that animal subjects inhaling nutmeg oil had an increased output of respiratory tract fluid. 
This action may be due to the active compound in nutmeg, which is camphene. 
Of course, as with other essential oils, you cannot use nutmeg oil undiluted, as doing so can cause irritation and other adverse effects.
