Mucus in the throat can be uncomfortable, especially when you have a cold, respiratory infection, allergies, or postnasal drip. Viral posts often promote a simple two-ingredient remedy and claim that it can “clear mucus from your lungs.”
The reality is a little more nuanced: no simple two-ingredient drink has been proven to literally clean mucus out of the lungs. However, some home remedies may help soothe an irritated throat and make a cough more comfortable.
Why Does Your Body Produce Mucus?
Mucus is a normal part of the respiratory system. It helps trap particles and microorganisms and protects the lining of the airways.
When you have a respiratory infection, allergies, or irritation, your body may produce more mucus. You may then experience coughing, throat clearing, congestion, or phlegm. nhs.uk
Importantly, mucus isn’t necessarily something that needs to be “removed.” Coughing is one of the body’s natural ways of clearing mucus from the airways.
Can a Homemade Drink Help?
A warm drink can be soothing, and drinking enough fluids is useful when you’re dealing with respiratory symptoms.
The NHS recommends drinking plenty of water during respiratory infections because fluids can help loosen mucus and make it easier to cough up. nhs.uk
One commonly suggested combination is:
Warm Lemon and Honey
Ingredients:
- 1/2 lemon
- 1–2 teaspoons of honey
- A mug of warm water
Method:
- Squeeze the lemon into a mug.
- Add the honey.
- Fill with warm water and stir.
- Sip slowly while warm.
The NHS notes that hot lemon and honey may have a similar soothing effect to cough syrup, although the evidence that it helps cough is limited. nhs.uk
Does Honey Actually Help With Coughing?
There is some evidence that honey can reduce cough symptoms, particularly in children over one year old with an acute cough. A Cochrane review found that honey probably provides some short-term relief compared with no treatment or placebo, although the evidence has limitations. Cochrane
That doesn’t mean honey removes mucus from the lungs. Its potential benefit is primarily soothing cough and throat irritation.
Important: Never Give Honey to Babies Under 1 Year
Honey should not be given to infants younger than 12 months because of the risk of infant botulism. Cochrane
What About “Detoxing” the Lungs?
Be careful with claims that a drink can “detox” or completely clean the lungs.
Healthy lungs have their own mechanisms for removing mucus and particles. A homemade drink cannot physically wash mucus out of the lungs.
If you have excessive phlegm, the important question is why you’re producing it. Causes can include respiratory infections, allergies, smoking, acid reflux, asthma, or mucus draining from the nose into the throat. nhs.uk
Simple Ways to Feel More Comfortable
If you’re experiencing ordinary cold or respiratory-infection symptoms, you can try:
- Drinking plenty of fluids
- Having warm drinks
- Resting
- Avoiding cigarette smoke
- Using honey in a warm drink if appropriate
- Keeping the air comfortably humidified
- Gently clearing mucus rather than repeatedly forcing a cough
Most uncomplicated respiratory infections improve on their own. nhs.uk
When Mucus and Cough Need Medical Attention
Don’t rely on a home remedy if symptoms are severe or persistent.
Seek medical advice if your cough lasts more than three weeks, keeps getting worse, or is accompanied by unexplained weight loss or other concerning symptoms. nhs.uk
Get urgent medical help if you have:
- Difficulty breathing
- Chest pain
- Coughing up blood
- A very severe or rapidly worsening cough
- Feeling seriously unwell nhs.uk
The Bottom Line
A two-ingredient drink may soothe your throat and help you stay hydrated, but there is no good evidence that a particular recipe can literally “clear your lungs of mucus.”
For ordinary coughs and respiratory infections, fluids can help loosen mucus, while honey may provide some short-term cough relief. If mucus production is persistent, severe, or accompanied by breathing problems or chest pain, the underlying cause should be evaluated rather than treated only with a home remedy. Cochrane
