Brown phlegm is excessive mucus excreted from your breathing passages that is not normally clear but is tinted with various causatives.
The most probable cause for coughing up brown mucus is smoking. Nicotine, tar and resins get into your bronchial and lung passages with every puff you take. Most of these harmful substances settle on the lining of the respiratory system organs causing brown phlegm symptoms. Heavy smokers can be recognized by extreme coughing and brown nails combined with characteristic nicotine odor that is very offensive to people around.
The best remedy against brown color of phlegm is quitting smoking. It may take some individuals up to a year to completely eliminate brown phlegm from their systems.
Another possible brown phlegm cause is old blood streaks being mixed in with throat mucus that is the result of a viral or bacterial infection you body is fighting. In this case, the best remedy is drinking lots of water or herbal teas that will help thin mucus and expel it from the body. Exercise caution with any over the counter cough medications that might suppress cough and lead to stagnant brown phlegm and worsening of your symptoms.
Acid reflux might make you regurgitate some of the food tinting your phlegm brown, especially if you’ve been consuming chocolate, red wine, or coffee. If you develop brown phlegm due to acid indigestion, watch out for bowel mucus which could be a warning sign of Irritable Bowl Syndrome.
Should you even develop bloody phlegm, seek doctor’s attention immediately.
