Dr Sebi Reveals Herbs For Mucus Removal

Mucus is a fluid that the body produces to line moist areas, such as the:
eyes
mouth
nose
sinuses
lungs
throat
stomach
intestines
reproductive organs
Most people only notice mucus when they are ill or exposed to allergens or irritants in the air. But glands in the areas listed above make mucus continually, secreting around 1–2 quarts daily.
Mucus helps with crucial functions, such as:
adding moisture to inhaled air
preventing moist organs from drying out
filtering, trapping, and eliminating inhaled microparticles or microorganisms, such as allergens, dust, smoke, pollution, viruses, bacteria, and fungi
fighting infection
Mucus helps trap microorganisms and microparticles on the surface of the lungs. Tiny hair-like appendages that line the lungs, called cilia, then beat in unison, creating a pulse that moves the entrapped particles up and out of the lungs.
Once the particle-filled mucus reaches the back of the throat, it typically moves down the throat without the person noticing.

After traveling down the throat, the mucus reaches the stomach, where it is digested and eliminated from the body in feces or urine. Mucus in the throat can also be coughed up and spit out.
