That stubborn lump in your throat. The rattling feeling in your chest. The constant urge to cough, swallow, or clear your voice.
Mucus is not necessarily the enemy—it is part of the body’s natural defense system. It traps dust, allergens, and microorganisms before they can travel deeper into the lungs. Tiny hair-like structures called cilia then move the mucus upward so it can be coughed out or swallowed.
However, colds, allergies, sinus drainage, smoke, dry air, acid reflux, bronchitis, asthma, COPD, and other respiratory conditions can make mucus thicker or cause the body to produce more of it.
Natural remedies may help thin mucus, soothe an irritated throat, and make phlegm easier to clear. They cannot cure pneumonia, asthma, COPD, or another underlying disease, so persistent or severe symptoms still require medical care.
Mucus vs. Phlegm: What Is the Difference?
Mucus is the protective substance produced throughout the nose, sinuses, throat, and airways.
Phlegm is the thicker mucus produced in the lungs and lower respiratory tract, usually in response to irritation, inflammation, or infection. When you have a “wet” or productive cough, your body is trying to move this material out of the airways.
The goal should not be to suppress every productive cough. Instead, support the body in making the mucus thinner and easier to expel.
1. Drink More Fluids to Thin Thick Mucus
One of the simplest remedies is also one of the most useful: proper hydration.
Water helps keep mucus thinner, allowing the cilia and cough reflex to move it more effectively. The American Lung Association recommends staying hydrated and using controlled coughing to help clear excess mucus.
Sip water regularly rather than drinking a large amount all at once. Warm liquids may feel especially comforting when the throat is irritated.
Good options include:
- Warm water
- Unsweetened herbal tea
- Clear vegetable or chicken broth
- Warm lemon water
- Caffeine-free infusions
Alcohol can contribute to dehydration, while excessive caffeine may worsen reflux or throat irritation in sensitive people.
2. Make Ginger, Lemon, and Honey Tea
This warming tea does not “detox” the lungs, but it can hydrate the body, coat an irritated throat, and temporarily calm coughing.
Ingredients
- 1 cup water
- 2–3 thin slices of fresh ginger
- 1 teaspoon honey
- 1–2 teaspoons fresh lemon juice
Instructions
- Bring the water to a gentle boil.
- Add the ginger and simmer for five minutes.
- Remove from the heat and steep for another five minutes.
- Strain and allow the tea to cool until comfortably warm.
- Stir in the honey and lemon.
- Sip slowly.
Drink up to two or three cups throughout the day if tolerated.
Honey has some evidence for reducing cough associated with common colds. However, it must never be given to a child younger than 12 months because of the risk of infant botulism.
People with diabetes should count the honey as added sugar. Ginger can aggravate heartburn or cause digestive discomfort, and concentrated ginger products may interact with medications.
3. Gargle With Warm Salt Water
When mucus collects at the back of the throat because of postnasal drainage, a warm saltwater gargle may loosen secretions and soothe irritated tissue.
Saltwater gargle recipe
- 1 cup warm water
- ½ teaspoon salt
Stir until the salt dissolves. Gargle for 20–30 seconds, then spit it out. Repeat two or three times per session and use up to several times daily.
Do not swallow the solution. Children should only gargle when they are old enough to do so without choking.
A gargle may help the throat, but it cannot reach mucus located deep inside the lungs.
