Phlegm, a thick substance produced by the respiratory system, helps capture allergens, dust, and germs. However, excessive mucus can result from colds, allergies, or infections.

To reduce mucus naturally, stay hydrated, gargle with salt water, inhale steam, apply a warm compress, or use honey and lemon in tea. A humidifier and nasal irrigation can also help. Avoid irritants like smoke and chemicals, as well as dairy and excessive sugar. Consult a doctor if symptoms persist or worsen despite these remedies.
