Natural and Medicinal Ways to Get Rid of Phlegm

Phlegm is caused by a viral infection. People usually contract phlegm when they are young and healthy. The virus enters the body through the nose, mouth, or eye.

The most common symptom of phlegm is a hacking, rattling cough that produces thick yellow phlegm. Other common symptoms include fever, sore throat, runny nose, and body aches.

Some people also experience fatigue and pain in the chest. The main cause of these symptoms is a mild upper respiratory tract infection.

Phlegm is sticky and thick, so it doesn’t usually come out easily. It can be hard to cough it up, too!

You might need extra help to cough out phlegm.

How to Treat Phlegm?

Phlegm is a thick, mucus-like substance that can build up in your throat and nasal passages. It’s often caused by allergies, sinus infections, or nasal congestion.

It is not difficult to get rid of phlegm. The first thing you need to do is make sure that you are taking care of yourself.

If you’re having trouble getting rid of phlegm and cough, try the following remedies:


  • You should drink more water and eat more fruits and vegetables to help your body get rid of the phlegm.
  • You should also take a bath or shower every day so that you can cleanse your body and remove the excess mucus that has built up inside your body.


Drink lots of water, hot liquids, soups, and tea with honey. These will make the mucus thin and allow it to pass.

Gargling With Salt Water

Saltwater is great for your throat because it helps remove germs and bacteria from your throat and nasal passages.

When you gargle with salt water, its cleaning ability makes sure that all the bad stuff gets flushed out of your nose and mouth so that you feel better as soon as possible.

Some people believe that using too much or too often will damage your throat or cause other health issues like soreness or irritation in your mouth or throat.

Over the Counter Medications

It can be hard to get rid of, but there are over-the-counter medications that can help.

Take an antihistamine (such as Benadry).

The most common over-the-counter medication used to treat phlegm is chlorpheniramine/phenylephrine (or Chlor-Trimeton).

This medication contains two active ingredients: phenylephrine and chlorpheniramine.

Each of these ingredients has different effects on the body and works together to treat a variety of symptoms associated with colds and other respiratory conditions.

Phenylephrine works by constricting blood vessels in the lungs, while chlorpheniramine acts as an antihistamine to block histamine receptors in the brain.

These two ingredients work together to reduce inflammation in your nasal passages, which helps relieve congestion and makes breathing easier for you.

Chlorpheniramine/phenylephrine comes in several forms: chewable tablets, liquid solution (concentrate), gel caplets, syrup (10 mg/5 mL), and syrup (2 mg/mL).

Cough syrup: Expectorants

These are usually very safe for adults, but be sure to check with your doctor first if you have any conditions that might be more sensitive to certain medications.

Guaifenesin (Mucinex) helps thin phlegm, making it easier to blow out or cough up.

Decongestant pills or syrup: Sudafed or Robitussin DM.

These should only be used when symptoms persist after trying over-the-counter remedies and home remedies, so talk with your doctor before taking these if you have any concerns about side effects or allergic reactions. Decongestants have pseudoephedrine.

Vapor Rubs

These are used to treat chest congestion and ease coughs.

Cough it up!

Well, don’t worry! There’s an easy solution: cough it up. If you’re coughing up phlegm, then you’re doing it right! But it’s important to keep at it until the phlegm comes out completely. Don’t stop until there’s nothing left in your throat or chest.

But if you keep trying, eventually it will come out. When it does, don’t forget to breathe through your mouth for a few seconds after each cough before you breathe in again.

This will help get rid of any excess mucus that might be lingering around in your throat.

If these methods do not work for you, then you should see your doctor about how they can help you with this problem.

Prescription Medicines

If you’re like most people, you know that the best way to get rid of phlegm is to just let it run its course.

But what if that’s not an option? What if you need to get rid of phlegm fast? Prescription decongestants can help you get rid of that stuffy, phlegmy feeling fast.

Just be sure to read the label and make sure that the medication is right for you.

Diprospan (diphenhydramine) is a medicine that helps thin out mucous so that it can be coughed out more easily.

Caffeine and Alcoholic Beverages

Avoid drinking alcohol or consuming caffeine after noon if possible; both of these can affect the quality of mucus in your throat and cause problems like coughing spells or worse breathing.

Both can cause dehydration and reduce the water content of mucus.

Blowing Out and Clearing Nasal Passages

You can use a tissue or a handkerchief to blow it out. This will clear the nasal passages and reduce sinus pressure.

Eucalyptus Oil

Eucalyptus is one of the most effective natural remedies for removing phlegm from your body and lungs. The oil has an antiseptic effect on the mucous membranes, which makes it ideal for this purpose.

It also has antipyretic and anti-inflammatory properties that help soothe irritation and inflammation inside your body.

The oil helps prevent congestion by opening up airways in your nose and throat so you can breathe more easily.

How to use eucalyptus oil:

You can use eucalyptus oil in several ways to treat your phlegm problem:

Massage eucalyptus oil into your chest, stomach, and throat area. This helps loosen up phlegm buildup in these areas.

Take a few drops of eucalyptus oil with a few drops of water and gargle. This helps loosen up mucus and debris in your mouth as well as prevent more buildup elsewhere around your sinuses or throat.

Add a few drops of eucalyptus oil to warm water every morning before brushing your teeth. This will help prevent plaque buildup in the nasal passages.

Quit Smoking

Smoking cigarettes can cause a lot of bad things, including phlegm.

If you smoke, it’s important to know that it will help to build phlegm. Smoking will cause excess mucus production and it tends to accumulate in the airways.

Elevation of the Head End

This will help you breathe easier. You can keep a few mattresses on the head end to elevate the head end.

Extra Tips!

  • Take a bath with lemon juice.
  • Try Eating More Garlic or Onions.
  • Add food rich in zinc and vitamin C to your menus.
  • Try to avoid smoking and drinking alcohol.

When to See the Doctor

  • You have a fever of over 101 degrees Fahrenheit.
  • You have a high-grade fever and you have a cough or any other symptoms of pneumonia (such as shortness of breath).
  • You have an ear infection that has caused a fluid buildup in your eardrum.

Phlegm is a mucus-like discharge that can be caused by some different things. It can be a sign that your body is working overtime to wash itself out, but in some cases, it indicates a more serious health condition.
