Something about mucus
Mucus is 95% water, 3% proteins (including mucin and antibodies), 1% salt and other substances. Mucin droplets absorb water and swell several hundred times in volume within three seconds of release from mucus glands. Mucus strands form cross links, producing a sticky, elastic gel.
Mucus-producing tissue lines the mouth , nose, sinuses, throat, lungs and gastrointestinal tract. Mucus acts as a protective blanket over these surfaces, preventing the tissue underneath from drying out.
But mucus is more than just sticky goo. It also contains antibodies that help the body recognize invaders like bacteria and viruses, enzymes that kill the invaders it traps, protein to make the mucus gooey and stringy and very inhospitable, and a variety of cells, among other things.
Bacterial infections often produce lots of green or yellow phlegm (mucous material), while allergic reactions frequently lead to lots of colorless mucus. In disease, excessive production of mucus in the airways is characteristic of illnesses such as chronic bronchitis, usually diagnosed by the large production of phlegm.
Excess nose mucus can occasionally cause nasal swelling and bleeding. It can also cause bad breath as it is high in proteins and is an excellent food source for anaerobic bacteria. Once this nose mucus settles on your nasal and throat lining, it can irritate, causing that constant phlegm in throat feeling, and can trick you into thinking that you may be coming down with a cold.
In the nature we find a lot remedies to get rid of mucus problems or to create the mucus.
Namaste!
