17 Effective Natural Home Remedies for Phlegm Relief

Persistent phlegm can make your day uncomfortable, causing congestion, sore throat, and difficulty breathing. Fortunately, there are many natural home remedies that can help loosen, thin, and expel excess mucus, restoring comfort and supporting overall respiratory health. This guide explores 17 evidence-based remedies to help you manage and minimize phlegm naturally, using simple ingredients and techniques that are accessible to most households.

What Is Phlegm?

Phlegm is a thick, sticky mucus secreted by the respiratory system, primarily as a protective response to infection, irritation, or allergies. While phlegm serves a role in trapping pathogens and debris, a persistent buildup can hinder breathing and become bothersome.

Signs and Symptoms of Excessive Phlegm

The following symptoms often indicate a build-up of excess mucus or phlegm in the respiratory tract:

• Coughing up mucus or persistent coughing
• Chest or nasal congestion
• Runny nose
• Sinus headache
• Sore or congested throat
• Shortness of breath or difficulty breathing

Most cases result from viral or bacterial respiratory infections, allergies, or irritants. Home remedies can often bring relief, especially when integrated early in the course of symptoms.

17 Natural Home Remedies To Remove Phlegm

1. Apple Cider Vinegar

Apple cider vinegar has been valued for its antimicrobial and mucolytic (mucus-thinning) properties. Its slightly acidic nature helps break down phlegm and supports the body’s natural defenses.

• Usage: Mix 1-2 tablespoons of apple cider vinegar in a glass of warm water. For taste and extra soothing properties, add a teaspoon of honey. Drink this mixture daily. Alternatively, gargle the mixture to ease throat congestion.
• Frequency: 2-3 times per day.

2. Essential Oils (Eucalyptus, Peppermint, Tea Tree)

Essential oils like eucalyptus, peppermint, and tea tree contain natural compounds that may help break up congestion, ease breathing, and provide antimicrobial effects.

• How To Use: Add a few drops of an essential oil to a bowl of hot water, cover your head with a towel, and inhale the steam for several minutes. Alternatively, use a diffuser in your room.
• Tip: Always dilute essential oils and avoid direct skin contact. Test for allergies first.

Why It Works: Eucalyptus oil, for example, contains eucalyptol, which acts as a decongestant and can help loosen mucus, while also fighting infection-causing microbes.

3. Salt Water Gargle

Gargling with warm salt water is a classic remedy for soothing an irritated throat and loosening mucus stuck at the back of the throat.

• Usage: Dissolve 1/2 to 3/4 teaspoon of salt in one cup of warm water. Gargle for 30–60 seconds, then spit out. Repeat as needed throughout the day.

Salt acts as a gentle antiseptic and can draw out moisture from swollen tissue lining the throat, reducing inflammation and aiding in expelling phlegm.

4. Ginger

Ginger root is rich in compounds like gingerol and shogaol, which possess powerful anti-inflammatory, antibiotic, and antitussive (cough-suppressing) effects.

• How to Use: Add freshly sliced ginger to boiling water to make tea, or chew a small piece raw. Adding honey and lemon enhances flavor and benefits.
• Frequency: Drink ginger tea 2–3 times daily.

Why It Works: Ginger helps soothe irritated airways, thin mucus secretions, and suppress coughing.

5. Garlic

Garlic contains allicin, a natural compound with broad-spectrum antimicrobial and expectorant effects.

• You will need: 4–5 garlic cloves, 1 cup warm water.
• What to do: Crush and eat the cloves directly with water or add to your daily meals. Alternatively, chew raw garlic cloves.
• Frequency: 3–4 times daily.

Why It Works: Garlic breaks down mucus, making it easier to clear, and combats infection causing respiratory issues.

6. Turmeric and Apple Cider Vinegar

Turmeric’s active component, curcumin, has known antimicrobial, anti-inflammatory, and antiseptic properties. When paired with apple cider vinegar, the effectiveness in thinning and loosening mucus may increase.

• Mix: 1 teaspoon turmeric, 1 tablespoon apple cider vinegar, 1 teaspoon honey, and a glass of warm water. Stir and consume.
• Frequency: Drink or gargle this mixture 2–3 times daily.

Alternatively, brew turmeric tea using 1 teaspoon turmeric powder and 1 cup boiling water. Steep, strain, and add honey if desired. Drink 2–3 times daily.

7. Humidifier or Vaporizer

Dry air can make mucus thicker and harder to expel. A humidifier or vaporizer adds moisture to the air, helping keep mucus thinner and naturally easier to clear out.

• Tip: Use a cool-mist humidifier, clean it daily, and keep it near your sleeping area to ease nighttime symptoms.

8. Honey

Honey is a traditional demulcent—meaning it coats and soothes mucous membranes. It also exhibits antibacterial and antiviral activity, reducing the source of infection that causes excessive phlegm.

• How to use: Take a tablespoon of pure honey directly, or dissolve in hot water or herbal tea. Adding lemon juice can boost effect and taste.
• Frequency: 2–3 times per day.

9. Onion

Onion is a natural expectorant and contains quercetin, which has anti-inflammatory and antimicrobial properties. Onion juice mixed with honey can help break up congestion.

• Suggestion: Grate a small onion, mix with honey, and consume. Alternatively, include more onions in your meals.

10. Lemon Juice

Lemon, high in vitamin C and citrus bioflavonoids, not only thins mucus but also boosts immune response.

• How to take: Mix fresh lemon juice with warm water and honey to drink as needed throughout the day.

The citric acid and vitamin C content help break down mucus and reduce inflammation.

11. Herbal Teas

Herbal teas made from chamomile, thyme, licorice root, peppermint, or mullein are excellent for soothing irritated throats and supporting mucus clearance.

• Suggestion: Brew herbal tea as directed. Drink 2-4 cups per day. Add honey and/or lemon for greater effect.

Herbal teas also promote hydration, which is important for thinning phlegm.

12. Cayenne Pepper

Cayenne pepper contains capsaicin, a compound that helps clear nasal and chest congestion, supporting mucus expulsion with its warming, spicy effect.

• You need: 1/4 teaspoon cayenne pepper powder, 1 tablespoon honey, 2 tablespoons water
• What to do: Mix ingredients into a paste and consume 1–2 times per day.

Spicy foods can help clear sinuses and break down thick secretions.

13. Jaggery

Jaggery is a traditional, unrefined sweetener believed to help clear lung passages and reduce allergy-related symptoms.

• You need: A slice of jaggery and 1/2 onion, chopped
• How to use: Mix chopped onion with jaggery and chew this combination 2–3 times a day.

Jaggery’s anti-allergic action may help reduce congestion and expel particulate matter from the respiratory tract.

14. Pineapple Juice

Pineapple juice contains bromelain, an enzyme mix with anti-inflammatory and mucolytic effects, helping to break down and loosen mucus.

• Usage: Drink one glass of fresh pineapple juice daily. For a targeted remedy, mix with honey and a pinch of salt.

15. Oil Pulling

Oil pulling is an ancient remedy in which oil is swished inside the mouth to reduce toxins and oral pathogens that can contribute to throat inflammation and excess mucus.

• How to do: Take one tablespoon of coconut or sesame oil and swish in your mouth for 10–15 minutes. Do not swallow; spit it out, then brush your teeth.
• How often: Once daily, preferably in the morning.

16. Orange Juice

Orange juice is high in vitamin C and may help thin mucus while strengthening immunity.

• How to use: Drink freshly squeezed orange juice once or twice per day.

17. Soups and Warm Fluids

Drinking warm soups, broths, and fluids can thin mucus, hydrate tissues, and calm throat irritation.

• Tip: Clear chicken soup, bone broth, or vegetable broth are especially effective. Hot herbal teas also count.

Staying hydrated is fundamental for defending against thick mucus.

Important Tips for Managing Phlegm

• Stay Hydrated: Drinking enough water keeps mucus thin and easier to expel.
• Avoid Dairy (if sensitive): Some find dairy thickens mucus, though evidence is mixed.
• Avoid Smoking and Irritants: Tobacco smoke and pollutants worsen symptoms.
• Rest: Give your body time to heal, especially when fighting infections.
• Elevate Your Head: Sleeping with an extra pillow may reduce nighttime congestion.

When to See a Doctor

While most cases of excess phlegm resolve with home care, seek medical advice if you notice:

• Phlegm persists for more than three weeks
• Colored phlegm (yellow, green, brown, or bloody)
• Associated high fever, chest pain, or shortness of breath
• Wheezing or signs of asthma

These could indicate more serious conditions requiring professional treatment.
